Cons — Lean and somewhat bright in the vocals department; top-end transients a bit fast.

Executive Summary

The LETSHUOER S12 is a well executed planar magnetic iem with all the traits adherent to this technology (low distortion, tight bass response, easy to drive, better sense of imaging, deeper stage, great bass extension).

Introduction

Planar magnetic headphones are popular because of their characteristic sound, but they have been traditionally overpriced and underperforming. They have therefore largely enjoyed a life in the shade.

That until a YouTuber started a hype putting the $220 7Hz Timeless ahead of its $1000 siblings, which attracted the attention of bargain hunters. Whilst this was a bit of a deception (the “other” $200 competition was not mentioned), it started a vivid and fruitful discussion all over the forums.

LETSHUOER (formerly known as Shuoer), a company from Shenzhen, China, jumped quickly on that bandwagon and released their S12 at $50-70 lower than the Timeless. They are mainly an OEM manufacturer who came on the scene with their ambitious $850 EJ07 that received a rather lukewarm reception by analysts (it was updated to the much improved EJ07M, which I am currently analyzing). LETSHUOER also did not impress with their budget fare such as the Shuoer Tape.

To take it away, the LETSHUOER S12 is a very good iem and a keeper for me. But can it prevail against the pricier 7Hz Timeless? You may be surprised…

Planar Magnetic Drivers – What do We expect?

The main purpose of a planar magnetic driver was to optimize bass response. In the earlier days, planar magnetic headphones reached down to 20 Hz whereas dynamic drivers only to 50 Hz. On the other hand, a dynamic driver has more punch and slam.

This has changed as slam in the planar magnetics has improved. Further advantages of planar magnetic drivers are: low distortion, tight bass response, easy to drive, better sense of imaging, deeper stage, and great bass extension.

LETSHUOER S12 Specifications

Physical Things and Usability

In the box are the earpieces, a silver-plated monocrystalline copper cable, 2 sets of LETSHUOER’s standard eartips (S/M/L), a container with foams, a much too small carrying case, and the usual paperwork.

The earpieces are of CNC machined aluminium, their build is rock solid. And they are relatively small, a characteristic also of the EJ07M. Small usually means comfortable, and that’s certainly the case here. Fit is also good for me – much better than the 7Hz Timeless with their larger “footprint”. The translucent stock eartips work well for me, but the seal is average for me (but also better than the Timeless).

The cable is somewhat unusual as it has a rather thick PVC coating, reminiscent of my mum’s clothlines. Well, it is not quite as thick but has a comparable tension/stiffness – and that without being heavy. It is funky to me, I quite like it. And it shows minimal microphonics when wiggled. The storage case is small so that I have not yet tried to squeeze the assembly into it.

In summary, the overall haptic is great and everything works right out of the box.

Sonic Characterization of the 7Hz Timeless

Equipment used: MacBook Air, Khadas Tone2 Pro/4.4 mm BAL & 3.5 mm SE or Earstudio HUD 100/high gain + JitterBug FMJ + ifi Audio iPower X; 4.4 mm stock cable with or without Cayin 4.4 mm to 3.5 mm adapter; Shuoer S12 stock eartips (translucent ones…the loaner came without eartips).

The 7Hz Timeless has been discussed in all details by the usual protagonists, including our own. Find the reviews of Alberto here and Durwood there, and Kazi’s elsewhere. And I have the Timeless on private loan while writing this.

The big schtick in the discussion, as mentioned before, is that planar magnetic iems have been underperforming and overpriced in the past and the 7Hz Timeless constitutes a much better value. At $220, a sweet spot for many, it has to prevail against an army of other models crammed in there. And, to give it away, I think the price is adequate but not sensationally low.

The 7Hz Timeless is all about bass. While it still lacks slam for many (a feature of planar magnetics) there is much bass. The extension is great, but mid-bass can be a bit much for me. It is soft, fuzzy, and occasionally boomy, and pounds mercilessly against my eardrums. I find this overwhelming and tiresome, but that’s subjective. Many may actually like that. For my personal taste, the midbass lacks composure, tightness, and spice.

Replacing the Shuoer S12’s stock ears tips with the JVC Spiral Dots took mitigated the “problem” to some extent, but did not entirely eliminate it.

Mid-bass appears to be up front on the soundstage in some tracks and covers up the whole image like a curtain, which makes for a shallow stage. And it provides for a very abrupt transition into the lower midrange up to bright, female voices. The lower midrange is naturally rather lean (another feature of planar magnetics) and vocals can be partially masked by the bass. Because of the lean and bright nature of the midrange, there can be shoutiness in some tracks.

But even in bass-less tracks vocals lack body and richness although they are articulate, very well sculptured, and natural. There is some brightness in female vocals, but they are “more lean than bright”. There is very good midrange clarity. All of these appear to be the result of the planar magnetic driver’s low distortion.

Treble is another mixed bag. Extension is great, treble resolution is good, upper transients are fast to oversharpened (“tizziness”), there is good air but also the occasional metallic sheen to it.

Technicalities are great. Timbre is ok, resolution and separation are good. Please check the big body of reviews for further details.

LETSHUOER S12 Tonality and Technicalities

Equipment used: Questyle QP1R on med. gain, Sony NW-A55; MacBook Air with Apogee Groove, AudioQuest DragonFly Cobalt, Khadas Tone2 Pro/4.4 mm BAL & 3.5 mm SE or Earstudio HUD 100/high gain + JitterBug FMJ + ifi Audio iPower X; stock cable or CEMA 6N OCC + OCC silver-plated 2.5 mm balance cable with or without the ddHiFi DJ44A adapter; stock eartips (translucent ones).

The LETSHUOER S12 carries most of the characteristics expected from a planar magnetic driver: low distortion resoling in good clarity, tight bass, deep bass extension, easy to drive, good staging…but, but but…

The S12’s bass is tight while digging deep. Midbass is well composed and focused, notes are not as rounded and soft (as in the Timeless), there is a crisp attack…and that’s the biggest different to the Timeless. A smaller but better focused kick.

This may have a few reasons, for example, the different housing shapes and the Timeless’ bigger contact area inside the concha (“bigger in-ear resonance”) and also the S12’s relatively higher frequency response above 2 kHz (which itself may be related to the housings).

The S12’s better mid-bass composure may trigger a chain effect in that the midrange is not masked and therefore clearer. Its transition from bass to lower midrange is much smoother compared the abrupt change in the Timeless…which results in a much more cohesive, balanced sound…which is the dealmaker/breaker for me.

Female voice remain articulate and lean, but are more forward and intimate, and a tad brighter, livelier, and spicier than in the Timeless. Vocals have a perceived higher energy in the S12, which plays them softer and therefore with lesser note definition. They are more prone to sibilance and shoutiness with unfavourable sources in the S12, but this has not been a problem for me.

Treble is also a mixed bad with the S12. Whilst extension and resolution are great, the transients are a bit fast up there and occasionally also yield that metallic sheen (“tizziness”) as in the Timeless.

As to technicalities. Staging is rather average, but tall, and reasonably deep (much deeper than in the Timeless). I find the staging adequate. Timbre is ok but benefits from a warm source such as the DragonFly Cobalt or Apogee Groove. Separation and instrument placement are ok. Resolution is absolutely superb and dwarves the Timeless’.

The Timeless, overall, sound a bit darker and less dynamic, more laid back but less composed than the more forward S12, which runs more into danger of being shouty. S12’s attack is crisper, Timeless have the softer transients. Note weight in the midrange is about even and could be better in both models.

When compared to a photo, the Timeless is more blurred and the S12 is sharper…but some may find the S12 overpixelated.

In summary, the S12 has the better composed bass, crisper attack, deeper stage, and better resolution than the Timeless. Everything is tighter in the S2. Compared to a car’s suspension, the Timeless is a comfortable SUV and the S12 is a sporty BMW.

In the end, it comes down to personal taste: pick your poison!

LETSHUOER S12 Driver = 7Hz Timeless Driver?

There are voices that speculate that both models have the same planar magnetic driver. After all, both models graph identically up to 2 kHz, and the differences above are just minor variations, possibly caused by the different housings. And some of the sonically perceived differences can be the product of the interactions between housings and our conchas.

We have also insider information that points to this as well as indirect evidence from upper harmonics measurements. Apparently, this OEM driver has been catching dust on the market for quite some time.

LETSHUOER, upon my request, are evasive and dwell on numbers: the Timeless has a 14.2 mm, the S12 a 14.8 mm driver – so they are different. Or one is a variation of the other? Stop, it all depends how (accurately) you measure them (e.g. front, back…).

The question is why nobody wants to admit to it? The answer is easy: to keep peaceful coexistence of companies as one could sue the other for “copycatting”. This could be a huge issue if one company’s model costs $$ and the competitor’s model (with the same driver) costs $$$$. Examples exist but are not widely publicized to protect the lucrative “kilobuck” markets.

So, unless somebody has cracked both models open, the driver question will be shrouded in mystery. At least for you :).

More LETSHUOER S12 Comparisons

We are in for some surprises. The S12 killed my beloved Final E5000 with my Questyle QP1R reference dap in these aspects: staging, transparency, really good transients, and upper extension. I hope I just had a bad morning when testing these two. The Final has a narrower stage lesser upper extension, less clarity…but more bass quantity.

The KBEAR TRI I3 Pro Pro is less cohesive than the S12 with a narrower stage, lesser resolution, and less midrange clarity. The I3 Pro is less balanced. Resolution is much better in the S12, which also has the crisper attack with more pizazz.

The Moondrop KATO offers a narrower stage because of early treble rolloff. It is slimmer in the bass and the upper midrange but still comes across as not less shouty. It also lacks richness in the lower midrange, a full orchestra’s crescendo comes across as somewhat lean in comparison. The S12 excels in resolution. It is much more bass dominated without overbearing midbass. Higher notes in horn sections as not as incisive as in the Kato, which is a bit scratchy in the upper mids in comparison.

The $600 LETSHUOER EJ07M shows better carved out vocals, is less bassy, has a narrower and deeper soundstage, better dynamics, and better resolution. Its presentation is lean(er) but never on the analytical side.

Concluding Remarks

I absolutely love the LETSHUOER S12. It is reasonably priced and I have yet to find a competitor in this price category that sounds as good. I also prefer the LETSHUOER S12 over the Timeless for five main reasons: better fit, tighter bass, deeper stage, better resolution, and a lower price.

LETSHUOER, ey! Never judge a book by its covers.

Until next time…keep on listening!

Executive Summary

The ddHiFi MFi06 and TC03 are digital cables that are well conducting, well insulated, built rugged and priced right. And they add optical appeal to our devices.

Introduction

ddHiFi have been favourites of our blog for quite some time. They produce very well designed, functional AND optically appealing audio accessories and even earphones.

I have tested their TC25i and TC28i adapters, their Carrying Case C-2020 as well as their Janus E2020A and Janus E2020B earphones. And I purchased a few of their audio adapters. For their accessories, the whole company is attached to our Wall of Excellence.

In this article, I am analyzing the MFi06 and TC03, two USB cables in the broadest sense. Both have a USB-C connector on one and, the MFi06 has a lightning plug on the other, and the TC03 a micro USB plug.

And all USB cables are equal, right? Zeros and ones transfer the sound, the stock cable is as good as the snake oil ones at $$$.

Erm, stop. Not always. The signal carried by the cable is not only zeros and ones (which are actually transmitted as voltage fluctuations), there may be some noise riding along the lines that affects sound quality. Two kinds of noise exist, “Electromagentic Interference” (EMI) and “Radio-Frequency Interference” (RFI).

If the data line is not effectively shielded, nearby electrical components (e.g., switching power supplies, other fluctuating electrical/magnetic fields from computer circuitry) can contribute to EMI that might pollute the USB data.”

Running power and data lines (from a phone or computer) through a single USB cable can cause additional interference and exacerbate the issue. Decrapifiers such as the AudioQuest JitterBug FMJ act as filters to reduce such pollution, but a “good” USB cable adds to this effect, too.

“Good” does not refer to the wire (that’s where the snake oil is) but to the insulation of the power and data lines against each other. In other words, a quality cable does not add anything, it makes sure that nothing is taken away from the signal quality.

A well-known example of the positive effects of insulation is the EarMen Sparrow dongle, that, when operated with a phone, can show strong interference in the shape of intermittent buzzing and clicking (subsides when switching the phone function off). The culprit is the stock cable, and a good third-party cable strongly reduces (but might not completely eliminate) the problem.

One measure of the shielding effectiveness of different cables, the resistance of shield terminations, was investigated in this thread.

Good-quality, well-shielded USB cables do not have to be expensive. USB audio pioneer Gordon Rankin reported very poor $$$ USB cables to me. It is all about the cable’s design, not the price.

ddHiFi are a company that offer a large range of imaginative, well designed, and well built accessories….and even a couple of earphones.

Physical Things

Both cables are 8 cm long. Wire material is high-purity silver-plated OCC copper.

Four strands of separately insulated wire serve as conductor. The inner insulation is teflon. The outer insulation is thermoplastic polyurethane imported from Germany. The aluminum alloy connector are cased in stainless steel to minimize external interference.

Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.

As it appears, these cables are technically sound. They feature good conductors and sufficient internal and external insulation. Sonically, they are indistinguishable from the OEOTG cable and one other brand of which I could not identify (see photo at the bottom of this article).

Haptically, the MFi06 and TC03 are vastly superior over the typical stock cables and the Apple Camera Adapter. The connectors feel rugged, the cable is flexible and the shiny, pearly white TPU is dirt and grease resistant.

And, let’s face it, these cables also add a jewelry effect to our gear. Yep, they don’t just feel good between the fingers, they also look good.

All good so far, only one worry remains: the MFi06’s battery consumption.

MFi06’s Battery Consumption

The MFi06’s lightning connector features a decoding chip which draws current from the phone. The question is how much it contributes to the phone’s battery drain.

I measured battery consumption of different dongles (AudioQuest DragonFly Red, Shanling UA2 single ended, Hidisz S9 Pro single ended) with the Apple Camera Adapter vs. the MFi06. I then repeated these tests with two other Lightning to USB-C cables (OEOTG and an unknown brand) for comparison purposes. All tests were performed under identical conditions. The absolute values are meaningless, what is important are the relative values.

.

Results:

1) The Apple Camera Adapter has by far the lowest power consumption.

2) In my 3 h tests, the 3rd-party MFi chip in the ddHiFi MFi06 cable consumed between 130 and 220 mAh (23%-36%) more (for my specific test parameters) than the one in the Apple Camera Adapter.

3) All three tested 3rd-party cables appear to have the same MFi chip (approx. same battery consumption with Shanling UA2).

4) Battery consumption of the ddHiFi MFi06 cable varies vastly between dongles. It is much lower for the DragonFly Red that consumes by far the least battery with the Apple Camera Adapter.

In summary, the MFi06’s power consumption is acceptable for today’s ever increasing phone battery capacities.

Concluding Remarks

The ddHiFi TC03 and MFi cables do what they are supposed to do: they work as promised while adding appeal to our devices. And they don’t break our piggy banks.

Until next time…keep on listening!

Gear of the Year: 2021 marks the blog’s third year and the second with 8 contributors. We collectively published almost 200 articles, mainly product reviews, but also technical information. Apart from receiving review units from manufacturers and sellers, we also purchased a lot…and we borrowed from audiophile friends and colleagues.

We are a heterogeneous bunch not pressed into templates by commercialism. Each of us enjoys maximum freedom. None of us gets paid. And it is this variety that makes this blog interesting. Two of us, Baskingshark and Kazi, have been drafted to also write for Headphonesty, which gives them more exposure and also access to very interesting gear.

We are currently experimenting with generic advertisements to recover our operating cost (Paypal does not work at all)…any money raised will go back into the blog. We remain non commercial.

Our main focus has traditionally been on earphones – we have reviewed almost 300 – but particularly DACs and amps also caught our attention this year.

As at the end of the previous years, we list our our personal favourites of 2021 – the portable audio we personally enjoyed most. There are no rules, we just tell you what we like. After all, the gear we use most is our best. And we attached some of this gear to our newly created Wall of Excellence, which averages all our opinions.

Enjoy this read and we wish you a happy and successful 2023!

Alberto Pittaluga…Bologna, ITALY

I’ve come accross quite a few interesting pieces of gear in 2021, mixed / hidden amongst piles of shameful crap. Nothing new, is it ? I’ll try to make a succint list of the most significant stuff I auditioned here. Most of these devices are also now part of my operative audio gear.

IEMS

Dunu ZEN (discountinued, was $ 699,00) : beyond spectacular microdynamics, resolution, layering and technicalities in general. A masterpiece.

iBasso IT07 ($899) : the sole real “direct upgrade” to Ikko OH10 I encountered as of yet. Same presentation, twice the refinement, at more than four times the price.

Oriolus Isabellae ($ 599) : somewhat “more V-shaped” alternative to Zen, delivering very similar technical prowess.

Ikko OH1S ($143) : a potential new join into the our World of Excellence roster as a sub-200$ allrounder

Headphones

Final Sonorous-II  (€ 300) : arguably by far the best neutral-tuned closebacks in their price category, staging and imaging easily compete with many lower tier openback alternatives.

Sennheiser HD600 (€ 310) : not a novelty for anybody but me, I’m sure. Quite simply: I got my first HD600 pair in 2021 and that’s why I’m listing it here. I presume no one needs a description. Do you?

Earbuds

Rose Mojito ($259) : superbly neutral-tuned high end earbuds with strong bilateral extention, beyond spectacular mids and vivid, refined highs in a fully holographic stage, with plenty of resolution and dynamics.

K’s Earphone Bell-LBS (€ 59,25) : mid centric buds delivering superbly organic vocals – both male and female – and very good trebles

K’s Earphone K300 (€ 28,59) : unreal sub-bass extension for an earbud, they deliver a very nice V shaped presentation while drawing an incredibly sizeable 3D stage. Presentation remembers a bit Ikko OH10, but in earbud form.

DAC/AMPs

Ifi Micro iDSD Signature (€ 749) : top sub-$1K mobile dac-amp. Very high quality DAC reconstruction paired with superbly transparent amping stage with power to spare for the most demanding planars and power deflation options to optimise low impedance IEM biasing. Truly a full step ahead of the competitors’ pack.

DAPs

Cowon Plenue 2 MK-I (€ 835) : hopped on this recently when I found a impossible to turndown openbox deal. Starting from my direct experience proving that there’s pretty much no game between proprietary-OS DAPs vs commercial-OS (read Android) DAPs, the former being in by far better position to achieve superior output sound quality, Plenue 2 represents a great companion to my QP1R offering a different / alternative optimal pairing opportunity for a few of my preferred IEM drivers.

DAC/AMP Dongles

This year’s experience proved to me that exclusively higher-tier (and price) dongles are able to deliver sound qualities worth the comparison with battery-equipped alternatives. Simply put: pretty much nothing until an Apogee Groove ($200) is really worth the price difference compared to the super-cheap Apple Dongle ($9), and even on the Groove some caveats apply (power needs, amp stage competibility).  That said, I really had pick one device “in the midfield” I’d pick the :

Questyle M12 ($139,99): while still not worth an inclusion on our Wall of Excellence, yet M12 runs circles around pretty much all similar or lower priced competitors I assessed in terms of extension, note weight, clarity and technicalities.

Biodegraded…Vancouver, CANADA

Doesn’t have anything to report this year.

Durwood…Chicago, USA

Shozy Form 1.4 has still been my go to earphone due to it’s warm inviting nature, great technical abilities and it feels great in my ears.

7Hz Timeless is another good buy late in the year for me, it’s a little more sub-bass plus analytical counterpart to the Shozy that has nudged the BQEYZ Spring 2 out of the way. A more detailed review is coming.

I rediscovered the Senfer UES for a quick throw around set, was hoping the Senfer DT9 was a slight improvement, but alas the Senfer UES sticks around instead. Sony MH755 is also perfect for quick on the go usage where I don’t need the universal fit in-ears.

Tempotec impressed me enough to consider the Sonata E35 for when good phone DAP’s are finally dead. Other than that, dongles are not my thing, and I have issues with some of Sony’s GUI decisions on the NW-A55 mainly related to playlist creation and long text support.

Lastly, the Questyle CMA Twelve would be an awesome DAC/amp combo to have, but my needs are more mobile. Perhaps when life slows down, but there are other bucket list items such as the Burson Playmate 2, RebelAmp, the Ruebert Neve RNHP, or RME ADI-2 that look interesting as well. Maybe someone will loan me one in 2022?

Jürgen Kraus…Calgary, CANADA

Earphones have traditionally been our main trade and there’s not many that stuck with me this year. First and foremost, I was impressed by the immersive and engaging sound of the single DD Dunu Zen that further excel in microdynamics. They are still very popular within our team.

Moondrop finally got it right with their tuning in the smooth and very pleasant sounding Moondrop KATO single dynamic driver. This model is generally well received. The JVC HA-FDX1 are still my standard iems for equipment testing, and an honourable mention goes to the Unique Melody 3DT for the clean implementation of 3 (!) dynamic drivers.

Another iem that fascinated me is the Japanese Final E5000. On the market since 2018, and very source demanding, this iem can produce a bass texture beyond belief. I have become a bit of a Final fanboy, as their products are unpretentious and natural sounding…and they fit my ears very well. I also purchased the Final E1000, E3000, and A3000…which get a lot of usage. No surprise that our Wall of Excellence is decorated like a Christmas tree by quite a few of these Japanese earphones and headphones.

Expanding my horizon into other devices, the Sony NW-A55 is a user-friendly digital audio player with great sonic characteristics and signature-altering 3rd party firmware options. But, most of all, it updates its music library within a minute or two. For the ultimate portable enjoyment, I discovered the Questyle QP1R dap...sounds simply amazing with the Final E5000. Found the dap on Canuck Audio Mart.

Dongles, battery-less headphone DAC/amps that turn any cheap phone into a decent music player, were big in 2021. Around since 2016, the market caught on to these devices. But out of the mass of dongles tested, the 2019 AudioQuest DragonFly Cobalt was the most musical to my ears. I also like the AudioQuest DragonFly Red and the EarMen Eagle (replacing the EarMen Sparrow which I sent to Biodegraded). For earphone testing (and bigger cans), I still use the excellent Earstudio HUD100.

For my full-sized headphone needs with my notebook, I discovered the powerful Apogee Groove, a current-hungry dongle DAC/amp that has been around since 2015. I am even portable around the house. As to headphones themselves, I am still happy with the Sennheiser HD 600 and HD 25, but also with the Koss Porta Pro.

For my desktop setup, I identified the EarMen Tradutto as being a fantastic DAC in combination with the Burson Funk amp. Currently testing the Tradutto with my big stereo system.

In summary, I learnt a lot in 2021…

My Take Home this Year

• The latest is barely the greatest…many old brooms get better into the corners
• Influencers are not always right (…to say it nicely)
• Measurements are overrated
• Timbre (degree of naturalness of sound) is underrated
• Source is super important and also underrated
• Group pressure through hype may become a sobering experience
• That groomed YouTube stuff is boring

Kazi Mahbub Mutakabbir…Munich, GERMANY

This year was very educational for me when it came to audiophilia. I got the chance to try out truly summit-fi setups and realized how good a system can sound. This also resulted in a sense of yearning where you keep comparing the gears you own with the ones you cannot own, at least not yet. Nonetheless, without further ado.

Headphones: The one headphone that has stuck with me throughout the year is the Hifiman Susvara. They won’t flatter anyone with the build quality but when paired with the right amp they sound astonishing. One of the most natural sounding headphones out there with exceptional timbre. A must listen.

Honorable mention goes to the Final D8000. Supreme bass that’s pretty much unmatched. On the budget side, I really liked the Final Sonorous-III. They are underrated and under-appreciated.

IEMs: When it comes to in-ear monitors, I have a hard time picking any single one of them as all of them fall short in one area or another. Nonetheless, the one IEM I’ve used the most throughout the year is the Dunu Zen. There is something truly addicting about their sound that makes me come back to them time and again.

However, the Zen is not the best IEM that I have heard throughout the year. That would probably be the Sony IER-Z1R or the 64Audio U12t. In the relatively budget realm, the 7Hz Timeless took me by surprise with their planar speed and excellent bass slam.

Source: Instead of going with separate sections for amps, DACs and such, I will just consolidate them into one.

Best desktop amp I’ve tried: Accuphase E380. One of those rare speaker amps that sound great with headphones.

Best portable amp I’ve tried: Cayin C9. It is the only review loaner in the past year that I have wanted to buy with my own money. I probably will, soon, budget permitting.

Best DAP: Lotoo PAW 6000, even though it can’t power difficult loads.

Best dongle: L&P W2. The only dongle that I found to be good enough to replace some DAPs.

Best DAC: Holo May L2. The price is extremely high but so is the sound quality. Exceptionally natural and neutral tuning. Another must listen.

And that’s a wrap. Have a great Christmas, and see you on the other side!

Gear of the Year (and other Favorite Things)

SMSL SU-9 DAC/Preamp—one of those pieces that makes you seriously question why anyone would spend more. A seriously good DAC which is even better as digital preamp.

Hidisz S3 Pro DAC/Dongle—lacks the juice to power challenging loads, but has an uncanny knack for enlivening and improving more efficient phones. Very refined, with impeccable bass control.

Cambridge Melomania TWS—ancient by TWS standards, and its rivals have more features and tech, but this may still be the best-sounding TWS you can buy.

Shozy Rouge IEM—like a really hot girl you get smitten by the beauty before you even delve into the substance. Properly driven, however, these sound just as good as they look, with estimable staging and clarity.

The Beatles, “Get Back” Documentary—as probably the only person on earth who hasn’t seen Lord of the Rings I was gobsmacked by how brilliant this film looked and sounded. The real surprise for me, however, was how natural  a musician John was—unburdened by technique, but soulful and  exploratory.  Poor George invokes your pity—a good writer forced to compete with two great ones– while Ringo wins the award for Best Attitude.

Bob Dylan, “Desolation Row”—I always found the lyrics impenetrable and a bit sophomoric, but the Spanish-influenced lead guitar part is incredible, with scarcely a phrase repeated throughout the full 11 minutes. I’d always assumed it was Mike Bloomfield, but it’s actually the harmonica virtuoso Charlie McCoy, who also plays the trumpet part of “Rainy Day Women”.

Reds, Pinks and Purples, “Uncommon Weather” In hope of finding something genuinely fresh I dutifully listened to the most-touted 2021 releases before fixating on this one, which (predictably) sounds exactly like 80s Flying Nun and Sarah bands.

More drama ahead? I published me take on the $5 VE Monk Pro earbud. They finally got the impedance down from 64 ohm to 32 ohm to present a truly “portable” earbud. I think my writeup is reasonably entertaining.

This “drama” over this Facebook post generated quite some outrage. What some people did not understand was that I don’t see a relationship between the hype and the quality of this iem. If you read between the lines, you’ll see my subtle criticism of peer pressure and compulsive buying triggered by pied pipers. 8000 views: goal achieved :).

Received the Fearless Barcelona recently for review. It is the cheapest Fearless IEM till now and the design belies the price tag. I love how they’ve designed the face-plate here.

Sadly, they sound horrible. Not recommended at all. Too much bass, highly recessed mids, zero treble extension. Get something else this holiday.

21-11-12 Alberto

Yesterday I received my new/old Cowon Plenue 2 and of course the very first impression is imprinted over my experience with QP1R. At first listen the P2 on its balanced output is quite nice, nicely extended and with a very good note weight. While less clean / revealing / detailed compared to the QP1R (whose single ended output is a quite good proof of why balanced is more a marketing name for decent quality output than anything else) on the other hand it offers a huge host of sound finetuning options, commencing from selectable reconstruction filters, to a very good “tweakable” graphical EQ module (not a true PEQ but close) and some further DSPs. Connectivity options are null / nil / zero – like QP1R. There’s not even BT – and that’s perfectly fine

Singles day is over…as the name implies, I didn’t buy a single thing. Our blog stats are surprising: 70% of our traffic stems from Google searches, and only 15% from Facebook. It is therefore not worth posting across FB groups…which is uncool anyway.

21-11-11 Jürgen

Today is 11/11 Asian Singles day. Not many exciting deals as far as I can see…but our blog experiences lots of views. In the meantime we published reviews of the FIIL CC2 and Oneodio Pro C reviews.

Finally got the Shanling UA1 review published. It is currently in Biodegraded’s hands for a 2nd review. Will have to finish the NiceHCK T2 EVO next week, and work on the Astell & Kern PEE51 dongle.

21-10-30 Alberto

Got my Hip Dac 2 review loaner unit in yesterday. First thing I noticed it came equipped with firmware 7.3 installed. The odd part is that on IFI’s website the 7.3 firmware is not listed under Hip Dac 2’s eligible downloads. Which means I could not recupe any “release info” about what’s different in 7.3 vs 7.2

While I was there, I also checked under Micro iDSD Signature’s section, and apparently firmware version 7.x has been removed from there too. Odd, at least. I put a question into IFI to get more info.

21-10-29 Jürgen

Published my Venture Electronics BIE Pro review on the blog. Submitted link to VE Clan Facebook group, where it got stuck in censorship, but was eventually posted after approval. That was only intermittent, I think I was tacitly expelled from that group after mentioning censorship. Be prepared that VE Clan Facebook group is manipulative as it presents cherry-picked information.

On another note, Loomis Johnson submitted his review of the Sennheiser CX-400BT True Wireless Earphones for publication.

21-10-28 Kazi

Received KZ ZEX. Their naming convention is making me go bad. Graphed it and labeled the graph wrong because these names all sound similar (ZAX/ZEX/ZSX). Either way, not too impressed with the sound. Kinda peaky in the mid-treble. Graphs show that as well.

21-10-27 Jürgen

21-10-25 Jürgen’s 10 Day Roundup

In the last 2 weeks, we published reviews of 2 totally underrated Final Audio headphones (Sonorous II+III) including some update earpads.

We identified some good TWS iems for the office in the Elevoc Clear.

We further think the Moondrop Kato is a winner (but need a second set for our European crew).

And we had a couple of second opinions of the GeekWold GK10, Tforce Yuan Li, SeeAudio Bravery, and Tanchjim Tanya.

We currently offer 281 earphone reviews.

21-10-25 Kazi

Received the iFi Hip DAC2 today, and the copper colorway will surely steal some glances. The sound isn’t changed much from the original Hip DAC (if at all) but it didn’t need to since the OG was one of the best DAC/Amps out there under $200. Full review in the works.

21-10-25 Jürgen

Worked on search engine optimization “SEO” all weekend after some trouble with Google. Also subscribed to webmaster tools of Bing and Yandex search engines. You can analyze the SEO of your own site here: https://rankmath.com/tools/seo-analyzer/

21-10-24 Kazi

Slow weekend, nice weather. Went out mostly to enjoy the fall colors. Also did some random photoshoot for the upcoming reviews. Also received the VE Monk SM recently. Not a fan. Shrill, sharp sound and technicalities are middling even for the $20 price bracket. At least it looks and feels nice in hand.

In other news, A&K released the SR25 mk. 2. Not a fan of the design at all. The tilted makes no usability sense. Also it’s basically the original SR25 with just a 4.4mm jack added. Meh.

The ongoing power crisis in China has led to increased operating costs as well as to price hikes of raw materials. Expect delays and price increases for your Christmas shopping.

Have not heard of 11/11 deals this year…strange.

21-10-22 Jürgen

Coming next on the blog (tonight my time) is Baskingshark’s review of the SeeAudio Bravery. We have a few more ready ones such as a tech article on “System on Chip” (SoC), that is dac and amp on the same chip. Another tech post will be an elaboration on the 1/8 rule on the example of the Apogee Groove.

Alberto will be offering reviews of the iBasso IT04, the Kinera Leyding earphone cable, and the Tanchjim Tanya in the very near future. These are ready. He is still working on a couple of Fearless models among others.

Also almost ready to go are reviews of the Shanling UA1 dongle, the VE Bonus Pro iem, and the VE Monk Go.

21-10-21 Biodegraded

Behind in evaluating various dongles sent by Jürgen for second opinions: Helm Bolt, Shanling UA 1, Earmen Sparrow, Tempotec Sonata BHD. So far, I’m surprised by the contrast between the Bolt and UA 1 (both use the same ESS DAC/Amp chip but yes, they sound a lot different) and by the bal vs SE contrast from the Sparrow. Comparisons will be made to the Audioquest DragonFly Black and ifi nano iDSD Black Label.

I’m also considering a winter project building this Pass Labs class A solid-state headphone amp to complement my tube hybrid and little USB- or battery-powered desktop/portable things. Much swearing will no doubt ensue. Right now though, have to clean the scratchies from the volume pot of an integrated amp that needs to be moved on.

2021-10-21 Kazi

Have had quite a hectic October, so couldn’t manage to publish anything. However, look forward to the “Review Extravaganza” over the coming two weeks or so. At least four articles are in the works and shall be published withing quick succession including:

• FIIL CC2 (a pretty good TWS)
• Moondrop Quarks
• Campfire Audio Holocene
• Campfire Audio Honeydew
• Final A4000
• Shanling Q1
• Cayin Fantasy

And just to close out, one of the photos I shot today (I think it came out pretty good). See you on the other side.

2021-10-21 Jürgen

Sitting currently on review units of Burson Funk amp and two Allo power supplies that may take some time. Almost ready is a review of the Unique Melody 3DT iem whereas the IKKO OH10 still needs some work. Overdue are reviews of several VE Electronics items as well as some ddHiFi accessories.

That famous Hidizs S9 Pro Copper edition dongle (limited to 500 copies) has been on its way from Calgary to Bologna for a good week now. Let’s see how fast Air Mail is.

Currently looking for a second Moondrop Kato review unit for our European chapter. After all, a single opinion is not sufficient for an item to qualify for our Wall of Excellence.

Cons — Included “Spring Tips” too small for big ear canals.

Executive Summary

The Moondrop KATO か と is a well-balanced, smooth sounding single DD earphone that sets a new standard in the $200 region.

Introduction

In the Japanese syllabary of Hiragana, か と stands for “ka to” or Kato, which is the 10th most Japanese surname. I struggled with these characters in my Japanese class at university during the mid 1990s…in order to end up in China later – many times. And yes, it was Chengdu, Sichuan, the home of Moondrop. C’est la vie. But we digress.

The 10 also stands for the number of Moondrop iems I have reviewed, following the company’s odyssey of tunings, always with micropore tape on standby to tame the iems’ upper midrange.

But, to my absolute delight, there is no more tape needed for the か と, pardon “KATO”. It is as smooth as silk. I said it weeks earlier in the SBAF forum, Moondrop are raising the <$200 bar with this model.

Now, before you pull the trigger on your order, please read on. The fact that this iem is astounding still does not mean everybody will love it. There are some strange listeners out there, after all.

The か と, erm…well…you know…is a further development of the $190 KXXS, which was a modification of the $190 KPE (Kanas Pro Edition). I don’t know the KXXS but found the KPE incoherent in that it was warm and thick at the low end and overly lean and neutral in the midrange. I did not like it.

The $110 Moondrop Starfield was said to be very similar sounding as the KXXS (although some disagree), but they are somewhat “loose” at the low end compared to the Kato.

The $90 Aria has recently rolled up the Moondrop field from underneath for being coherent, articulate, but it is also a bit peaky, which nevertheless made it my favourite Moondrop model so far…until now. Spoiler alert: the KATO is even better in that it is smoother and richer. Everything in the KATO is bigger compared to the leaner Aria. It is like a cappuccino with generous whipped cream vs. a strong cup of black tea.

Specifications

Physical Things and Usability

In the (rather big) box are the two earpieces, 2 sets of screw-on tuning nozzles (steel and brass), a carrying bag and a carrying case, a set of foams and a set of Moondrop’s own “Spring Tips”, the earphone cable, and the unavoidable paperwork. Generous!

The steel earpieces are virtually identical with the KPE’s and KXXS’ from the outside, but inside they host a new Ultra-Linear Technology driver for improved dynamics and resolution (info on product page). All these earpieces have the same comfortable fit.

The cable is bordering on spectacular – and you know I usually don’t care much about those. It is of medium weight and intermediate stiffness with fantastic haptic and no microphonics.

The in-house developed “Spring Eartips” also feel superb: they have a rather thin membrane and feel extremely grippy. Unfortunately, they are rather small so that even the largest pair does not fit my ear canals. In contrast, the foams are of generous sizes. And since foams generally do not do it for me, I have good results with the Final E tips (clear version). With those, isolation is ok.

The Moondrop KATO can be driven with a phone, but they get more life when amplified.

Tonality and Technicalities

Equipment used: Sony NW-A55, MacBook Air + Audioquest DragonFly Red/Earstudio HUD100/EarMen Eagle + AudioQuest JitterBug FMJ; steel and brass stock nozzles; Final E tips (clear version).

Sonically, the Moondrop KATO has no sharp corners or other sonic vulgarities, everything is well measured and well composed. To achieve this, low end and midrange have been dialled back compared to previous models.

Despite lesser quantity, the low end is digging deep down into the lowest frequencies with the bass climaxing at the transition to the sub-bass. This avoids a thumpy midbass. The low end is weighty with enough rumble, and the mid bass has a good punch, but both are well dosed and not overwhelming – and rather smooth and subtle. Decay is realistic and there is no bleed into the lower midrange. The bass adds some colour to the mix.

In contrast to its predecessors such as the KPE, the KATOs’s midrange also has some colour which harmonizes much better with the low end. The KATO’s midrange is fuller bodied with well rounded notes and a good weight but also offers great clarity, transparency, and spatial cues.

New is the lack of an upper midrange (and treble) peak which attenuated and sharpened vocals in the Starfield or, to a lesser extent, in the Aria. Nothing aggressive in the KATO. Hurrah, Moondrop finally did it and I can retire my micropore tape I used to stick onto so many Moondrop nozzles to tame the upper midrange.

Treble has better extension than (many) previous Moondrop single DD models but always remains sweet, composed, and well resolving, contibuting to KATO’s overall cohesion.

Staging and imaging are outstanding. Soundstage has good depth and height at average width. There is no congestion, great three-dimensionality, very good separation and layering. Transients are realistic, which adds to the smoothness.

I summary, the Moondrop KATO is one of (if not) the smoothest and most homogenous iems I have tested.

All of the above was determined with the steel nozzle. The brass nozzle adds body to the sound but also removes clarity. I therefore prefer the steel nozzle, which was also used for the comparisons below.

Moondrop KATO compared

Since Moondrop have pursued their VDSF target in their recent single DD models, their frequency responses are all rather similar – but not their sound. The biggest difference is probably between the KATO and the $800 Moondrop Illumination in that the latter has a much more boosted upper midrange, which made it somewhat shouty to my ears. I much prefer the much cheaper KATO.

In comparison, the Moondrop Aria has more bass and a prominent treble peak, which makes it overall more aggressive sounding. The Aria is also leaner, cooler, and edgier sounding with inferior imaging. So yes, the KATO is a worthy upgrade.

The Moondrop Starfield is looser and less measured across the frequency spectrum with earlier treble rolloff and a narrow stage. It is also behind the KATO in terms of technicalities and I even prefer the Aria over the Starfield.

The $250 single DD JVC HA-FDX1 (on our Wall of Exellence “WoE”) have been a very highly regarded standard staple for the last 2 years, mainly because of their rather accurate tonality at a very reasonable price. The JVCs are more neutral and crisper in their attack compared to the warmer, smoother and more immersive KATO, which lack the JVC’s upper midrange glare.

The JVCs have a flatter stage, the perfect bass, they are harder to drive, but they are tonally very accurate and are even cleaner sounding than the KATO. It is a bit silly to compare these as both are superb in their own way.

The IKKO OH10, also on our WoE, has a more pronounced V-shape than the KATO with a thicker, boomier, more impactful/more satisfying bass and more recessed leaner and sharper, that is more energetic midrange. This results in a huge soundstage. Again, the IKKO OH10 are a different beast and not exchangeable for the Kato.

Finally ddHiFi Janus2 (taped) is shouty and thinner (in the midrange) sounding than the KATO. It also has less bass. The Janus2 is not remotely as smooth and cohesive as the KATO.

Concluding Remarks

Moondrop finally got it 100% right. Their KATO is a super smooth performer with a superb overall presentation. It is technically and tonally good enough to please both analytical and recreational listeners. You cannot do better at this price, as simple as that. Just bo and guy it. What…?

Until next time…keep on listening!

Cons — Voices rather lean (easily fixable).

Executive Summary

The ddHifi Janus2 (model 2020B) is a moderately warm and technically very capable single DD earphone with a bright tilt in the midrange. It is sonically completely different from the Janus1 (2020A).

Introduction

In the previous article we had a look at ddHifi’s first earphone, the Janus (2020A or Janus1). This is my analysis of the Janus2 (2020B) which replaces it. As it appears, some early adopters of the 2020A may have decried a lack of sub-bass extension so that ddHifi modelled their follow-up according to some frequency response model curve (I speculate).

Janus1 sound(ed) great to me as the tuning is matching the driver. Other examples of great-sounding iems with “unusual” frequency responses are the Dunu Zen, the Final Audio E3000/E5000, and Meze RAI Solo, to name just a few. There are, on the other hand, iems that sound meh because they were squeezed into a model curve. The SeeAudio Yume comes to mind.

What this tells us is that quantity (“frequency responses”) does not always translate to quality (“sound”). In fact, it never really does, but some frequency responses may ring alarm bells.

One thing up front, the newly designed Janus2 has sonically little in common with the Janus1: it is bassier, brighter, and faster. Whether this means is it more balanced than the Janus1, we will work out as follows.

Optically, not much has changed, there is more steel (and less “transparency”) in the earpieces, but there is a new, “faster” driver with high-speed tweeter inside.

Specifications

Physical Things and Usability

In the box are the two earpieces, the C80A PU leather storage case ($25) with magnetic lock, the BC110A silver plated ofc cable with MMCX connectors ($46) and the C10A magnetic cable clip ($8), 2 sets of silicone eartips (red-stemmed “bass type” bulbous narrow-bores, and black-stemmed “treble type” short wide-bores), 10 MMCX hole dust covers, and the usual paperwork. As you see, you can purchase some of the included accessories individually, and they add up to almost $80.

The earpieces preserve the Janus1′ innovative shape and still feature the dual connectors (2 pin, 0.78 mm and MMCX).

The cable’s wires are a combination of OFC (oxygen-free copper, for grounding) and silver-plated OFC (for data transmission) that comes with MMCX connectors and a 3.5 mm plug. The MMCX connection is the tighest fitting I have experienced. Cable’s outer material is medium hard PVC, which gives the cable just the right elasticity and keeps it free from microphonics.

The cable is devoid of (constricting) earhooks so that the earpieces can be worn over and under ear. In summary, an excellent one.

The case is still stain and fading resistant, lined with microfibre, and with a magnetic lock, but the material is now PU leather, which is smoother than the Janus1’s cowhide leather (but lacks that natural smell).

The reversible magnetic cable clips is strong enough to hold the Janus2 on the fridge door (a first step to our Wall of Excellence?) and on my jacket.

And like the Janus1, the Janus2 are very comfortable whilst isolation is soso. The included wide-bores worked again best for me. With its higher sensitivity, the Janus2 is easier to drive than the Janus1.

As with the Janus1, the whole assembly, that is earpieces and cable, is extremely light and small, and fit in the smallest shirt pocket.

Tonality and Technicalities

Equipment used: MacBook Air, iPhone SE (1st gen.); AudioQuest Dragonfly Red/Earstudio HUD100 w. JitterBug FMJ, AudioQuest DragonFly Cobalt, EarMen Eagle; Astell & Kern PEE51; both sets of stock tips (red-stemmed “bass type” bulbous narrow-bore, and black-stemmed “treble type” short wide-bores); 200 hours of break in.

ddHifi have tuned the new 10 mm high-speed driver of the Janus2 completely differently compared to the original Janus1 by adding bass and upper midrange (for balance) but the treble (rolloff) remains approximately the same.

In the big picture, this results in a well-tempered DD sound, big staging, lushious spatial cues, good dynamics and excellent note definition, but a leaner midrange (compared to the Janus1) with grain at higher volumes and the occasional sibilance. In my testing, the Janus2 sounded best with a warm, organic source such as the two DragonFlys or the slightly cooler EarMen Eagle.

Sub-bass extension is (now) adequate, you get a good rumble at the low end, but it is still not record breaking deeply rooted. Mid bass is punchy and dynamic with a satisfying kick. There is good speed and texturing…it is on the faster side of the dynamic drivers I have tested. And yes, there are more than enough bass and impact, way more than in the Janus1.

Male and female are natural and well sculptured, with very good note definition and articulation, but they are also lean and frequently sharp, which can get fatiguing. A bit more body would have done them well. Read on…

That boosted upper midrange may help with the perceived technicalities and provide for a clean and transparent midrange, but it makes the lower midrange thin and breathy. And yes, the midrange is shouty at higher volumes and high violin notes can be grainy, but it is well resolving and clean at lower volumes. But…

As always with peaky iems, I put a strip of micropore tape over the nozzles (80-90% of the screens covered), which calms the upper midrange down (results vary between earphones). In this case, it removes most of the shoutiness and adds body to the vocals – and brings the bass out.

After this reversible fix, voices are not aggressive anymore and the richness of the vocals are now acceptable. Problem solved. ddHifi should have not boosted the 4-6 kHz that much, and they should have implemented the pinna gain between 1 and 2 kHz (instead of 3 kHz).

Note definition is very good across the midrange right into the well-resolving lower treble: high piano notes are well defined with cymbals, although somewhat back, are crisp. The recession in the lower midrange from 6 kHz progresses right into the upper midrange above 10 kHz which moves the vocals ahead of the high notes.

Some of the very high notes are tizzy, probably related to the 15 kHz spike, which definitely adds fake resolution, air, and sparkle to the midrange. The lower treble is largely similar to the Janus1’s, that is sweet and polite – and therefore pleasant on the ear.

Soundstage is rather wide with decent depth and height. Imagining, spatial cues, and 3D transparency are very good and so is separation. All better than in Janus1. The driver speed makes this possible and is also responsible for the excellent dynamics and attack. There is no smearing going on.

Timbre is organic with that bit of brightness added. Get yourself some micropore tape and make it darker…

Janus2 Compared

The $199 IKKO Gems OH1S 1 DD +1 BA has a much lesser bass and treble extension and is therefore less V-shaped. OH1S’s vocals are more forward and richer, but also with a tendency toward brightness.

The original Janus1 lacks the low-end extension, and vocals sound thicker owing to the more contained upper midrange. To me the Janus1 has a tad too little upper midrange and the Janus2 has too much. This also results in a narrower stage in the Janus1. The midrange of the Janus1 is somewhat reminiscent of the Sennheiser IE 500 PRO. It can also not compete with Janus2 in terms of dynamics.

The frequency responses of the Janus2 and the very well resolving NF NM2+ look similar, but the latter is much hotter in my perception – and way more analytical. Too hot to handle for me.

Concluding Remarks

ddHifi have produced a very good sophomore iem, but with a caveat: 2 steps forward and 1 step back. They implemented a faster dynamic driver and tuned it according a model curve as it seems. Out came a more dynamic, better resolving, better imaging, better staging iem (than Janus1 2020A).

However, the Janus2 falls short in the vocals department by an overdone upper midrange boost. Luckily, this can be fixed by very simple means. If ddHifi had tuned it slightly better, the Janus2 could be considered being fantastic.

If you own the Janus1, should you…? Erm…I don’t know but the Janus2 is a completely different beast.

The Janus2 is as innovative and classy as the rest of ddHifi’s offerings, it truly is a good sounding work of art and deserves a design award.

Until next time…keep on listening!

The post ddHiFi Janus2 (E2020B) Review – Second Coming appeared first on Audio Reviews.

Cons — Poor bottom end extension.

Executive Summary

The ddHifi Janus (also referred to as Janus1 or E2020A) is a well-accessorized, mid-centric, articulate iem that is very well suited for listening just with a phone. It has been superseded by Janus2.

Introduction

ddHiFi have been bringing us innovation + functionality + design since 2017. Their products work well, look good, and it is no surprise that the whole company made it onto our Wall of Excellence. Most recently, the company added a new category to their portfolio: earphones. And the Janus is their first iem release. As you can see from the images, the Janus follows the design ideas of some of the ddHifi adapters, which makes it optically distinct from any other iem on the market.

Specifications

Physical Things and Usability

In the box are the earpieces and accessories worth >$90 when purchased individually: the $60 BC120A (Forest) Air Series Earphone Cable, the $25 C80B Genuine Leather Storage Case, an $8 C10B Magnetic Cable Clip, 2 sets of eartips (red-stemmed “bass type” bulbous narrower-bore, and black-stemmed “treble type” short widebores), and 10 MMCX port covers. The whole assembly, that is earpieces and cable, are extremely light and small, and fit in the smallest shirt pocket.

The earpieces contain a flexible printed circuit board that contributes to their lightweight. They feature two different connectors on opposite ends, one 2pin/0.78mm, and an MMCX. That’s the reference to Janus, the Roman god of beginnings, gates, transitions, time, duality, doorways, passages, frames, and endings…an obviously very flexible deity. He is commonly represented by a double-faced head (frequently on antique coins).

The very light Forest cable comes with with MMCX connectors and a 2.5 mm balanced CNC machined alloy plug. It contains 4 conductors made of 6N OCC copper (that is 99.9999% purity) mixed with kevlar fibre. The outer material is interesting as it looks and feels waxy (= dirt resistant) like Twizzler candy, made of thermoelastic elastomer. The cable is free of microphonics. A truly superb cable.

The case is made from cowhide leather and coated to be stain and fading resistent. It smells nice. The interior is lined with microfibre and the lock is magnetic. Also interesting is the double-sided magnetic cable clip that adheres to the case, if not needed, but can also be used to attach the cable to a coat or bag when used on the road. See the Gallery section at the end.

The earpieces are extremely comfortable and can be worn over and under ear as the cable does not have any earhooks. The wide-bore tips worked best for me. The Janus are reasonably easy to drive (despite their 93 DB sensitivity) and some rare earphones that do not substantially benefit from amplifying. They sound great with my iPhone.

Tonality and Technicalities

Equipment used: MacBook Air, iPhone SE (1st gen.); AudioQuest Dragonfly Red/Earstudio HUD100 w. JitterBug FMJ, AudioQuest DragonFly Cobalt, both sets of stock tips (red-stemmed bass type, and black-stemmed treble type); 200 hours of break in.

O dear, that graph looks more like of an earbud than of an iem, some “graphologists” may say. The low end is already rolling off in the lower midrange and the upper midrange is rolled back. One would expect the Janus1 is vocal centric with a wide stage and no congestions by a bass bleeding into the lower midrange. And yes, that’s right. And the obvious absence of a 2-4 kHz peak could mean it is not shouty and fatiguing. Yes, you are right.

But, most of all, the Janus1 does actually sounds darn good to my ears. So good that I have used it a lot in the last few weeks, particularly before going to sleep. As said, it sounds great just with my iPhone, no amplification needed. Another case of tuning that fits the driver (and not the other way round)?

The overal sonic signature is marginally warm with the smallest tinge of brightness. Presentation is relaxed, cohesive, and imo well suited for chilling.

Now from graphology to the cumbersome listening business: you think there is no bass extension? Actually not quite. The extension is principally there, it is just “a bit hesitant” and not very strong and the rumble is very subtle. But the (relatively) nimble driver makes somewhat up for the lack of quantity. The lowest frequencies remain well composed and are not fuzzy. Bass remains subtle and relatively tight. Punch and dynamics are there, too, but also subtle.

Vocals, male and female, are intimate and forward, which is probably the Janus1′ biggest asset. They are natural, of medium weight, and with good (note) definition and excellent articulation. There is no sharpness, rather the notes appear to be coated by a thin film of silk. Very pleasant and relaxed on my ears. The subtle bass also keeps the midrange transparent and clean. All this makes for great speech intelligibility.

The Janus1 has therefore become my go-to for listening to talk radio as it brings out voices without congestion (from the low end). If you think most iems are good for talk radio, think again.

Lower treble is back, and treble below 15 kHz is sweet and polite. No hint of stridency, just pleasant. Cymbals are lined up behind the vocals, but, like the vocals they are well defined. No smearing. The downside is limited air and sparkle, which again benefits the voice reproduction. Can’t have it all.

Stage is wide but not deep. Nevertheless, spatial cues and placement on stage are good, however the stage can get crowded. Dynamics are good to my ears and there is decent articulation. Yes, there is enough slam for me, but it may be too polite for others. What did I say, chilling? Timbre is excellent, spot on realistic.

The Janus1 is so unique in its design, sonic signature, and accessories, that it is pointless to compare it to other iems. And even more so as it has been discontinued.

Fun Fact: Other examples of great-sounding iems with “unusual” frequency responses are the Dunu Zen, the Final Audio E3000/E5000, and Meze RAI Solo, to name just a few. 

Concluding Remarks

In summary, the Janus1 (2020a) is a vocal-centric, organic sounding earphone with an extra portion of silk, giving a relaxed presentation, which makes for a chilling and civilized listening sensation. It is not an adrenaline pump or a bass canon, but rather a well measured set that even works well with a simple source such as a phone.

Once you get your ears into its sonic signature, you can’t let go for hours. The Janus1, just like so many other product by ddHifi, are from the category “and now something completely different”.

The Janus1 has been discontinued and replaced by the Janus2, which is a totally different beast. You will find the Janus2 review (with Janus1 comparison) in this article.

Executive Summary

The ddHiFi Carrying Case C-2020 is a well-made textile-leather carrying case for personal audio gear. It is roomy enough to hold a couple of daps or portable headphone amplifiers plus accessories.

Introduction

I started this blog over 2 years ago, focusing on earphone reviews. This didn’t change much even when we became more authors. But we eventually diversified into esoteric things such as earpads, eartips, earphone cables, even microphones and after-market strain reliefs. We found ways to separate the good from the bad in every possible genre.

When I first talked to Lily at ddHifi, we could not find an item to review. I simply did not see any application for their products. This changed rapidly when I needed an adapter for connecting 2.5 mm balanced cables to a single-ended 3.5 mm socket. I ended up ordering three different ones and was so happy with them that I finally reviewed these two adapters for ddHifi.

And I started liking their stuff. Very much so. Everything by ddHiFi I have touched has turned out to be superb in terms of both functionality and quality. The C-2020 case is no different.

I see the C-2020 carrying case as a challenge for me as a reviewer. Not so much for the written account – other than perhaps conveying the message as compact as the case itself is. No, I was really keen on doing a video on something as exciting as a case – and make the video actually really exciting. You can see the result here:

Specifications

• Dimensions: 24*17*8 cm
• Weight: 410 g (excluding strap)
• Outer Material: bifilar fabric and Italian cowhide leather
• Inner Lining: polyester and elastics
• Zippers: dual, 2-way
• Straps: 2 (hand and shoulder)
• Tested at: $57
• Product Page: ddHiFi
• Purchase Link: dd Official Store

Physicalities and Functionality

Workmanship is top notch: outer shell material is sturdy and appears to be water repellent, and it is nicely alternating with leather pieces that make the whole case smell good. Really good.

The double zippers appear to be rugged and sturdy. And the inner polyester lining is standard quality. The case can be worn over the shoulder or on the wrist. Wrist strap and shoulder strap are included.

There are two main compartments, a deeper upper one and a slimmer lower one. See images below. From now on I recommend watching the accompanying video as writing the obvious can become a boring read.

UPPER “DEEP” COMPARTMENT: for two bulkier items such as daps/headphone amplifiers and 2 iPod classic shaped devices/phones. The compartment can be subdivided by two dividers attached by velcro to fit any device. Rubber straps attached to the bottom offer additional hold.

LOWER “SHALLOW” COMPARTMENT: for SD cards, cables, dongles, adapters, earphones.

You see the case in action in the Gallery at the bottom of this article.

What My Wife Says

That’s the real test. Somebody hanging out at the Coach outlet store in Las Vegas should know. My wife says about the C-2020 case: attractive; good quality, great stitching, good leather, nice compartments, practical…if this was from Fossil, it would be way above $100. Well, she does not see a reason for carrying strap.

ddHifi C-2020 Case Compared

Oh, these silly comparisons. Louis Vuitton does not offer an audio gear case. And if he, did, we could not afford it. But let’s face it, the amazon basics polyester-padded cardboard box I had before was a piece of junk.

Concluding Remarks

Whatever ddHiFi releases appears to be well thought out, beautifully designed, functional, and built well. The C-2020 carrying case fits this bill. I have been using it to store my portable amps since the day of arrival. For the price of yet another Chi-Fi earphone, I’d rather treat myself to a nice case.

Until next time…keep on listening!

I thank ddHifi very much for providing this case for the sole purpose of making a funny video – which nobody watches. Thank you very much indeed.

EXECUTIVE SUMMARY

The EarMen TR-Amp is a powerful neutral but not sterile of generic sounding integrated headphone amp (dac/pre-amp) that drives headphones up to 300 Ω) with ease. Made in Europe.

INTRODUCTION

EarMen recently appeared big on our radar out of nowhere, with their two models the TR-Amp (“transportable amp”) and the Sparrow dongle. The company is a subdivision of premium manufacturer  Auris Audio. Earmen is registered in the US, where most of its stakeholders are from. The new Chicago warehouse has its focus on the North American market. The production is currently in Krusavec, Serbia [video of production facilities]. EarMen is “Made in Europe”.

I have used the EarMen TR-amp for 4-5 months, mainly with the 300 Ω Sennheiser HD 600 headphones. This worked so well and the TR-amp so so easy to operate that I had real problems writing an actual review other than telling you that it “works well and is really good”.

I apologize to EarMen that it took me so long to write this article.

Product page: https://earmen-shop.com/products/tr-amp

PHYSICAL THINGS

In the box are:

• TR-amp
• USB-C to USB-A cable, 1 m
• rubber ring (for strapping TR-amp to phone)
• storage meshbag
• manual/warranty card

The case is of sturdy aluminum, knob and switch are metal, there is nothing plastic. Rubber feet on the bottom prevent the metal chassis from being scratched/scratching the underlying surface such as a smartphone. The build is so sturdy that you can probably use it in self-defence – and it will still work thereafter.

The EarMen TR-amp features the TOTL ES9038Q2M SABRE dac chip and the Texas Instruments TPA6120 headphone amplifier chip. 

FUNCTIONALITY

The EarMen TR-amp connects to smartphones vial plug ‘n’ play, it needs a driver for Windows (download) and none for the Mac.

WHAT IT DOES

• Can be connected to phone or Windows/Mac computers or Android/iOS sources
• Works as a pre-amplifier or dac when connected to a dedicated headphone amplifier
• Plays two earphones/headphones simultaneously through its two outputs (3.5 mm/6.3 mm)
• Drives small loudspeakers through its RCA outputs
• Plays and charges simultaneously through its two USB-C ports (5V power supply/charger)
• …Or runs on its built-in 3700 mAh battery
• Handles even power-hungry headphones well, imo up to 300 Ω

WHAT IT DOES NOT

• There is no choice of different digital filters
• It has no gain switch
• The output impedance is fixed
• Cannot be used as an amp only as it has no analog inputs

The EarMen TR-amp is a rather large for use on the road – I’d store it in my pocket rather than strapping it onto my phone. I like using it in bed with my phone, where size does not matter…at least amp size does not.

OPERATION

Operation is straight forward. “The music plays” – as they say – in the front and back panels…

Front Panel

The front panel of the EarMen TR-Amp features 2 outputs: a 3.5 mm and a 6.3 mm, which points to its particular suitability for full-sized headphones. The “On-Off/Volume” is nicely protruding out and therefore convenient to handle. That little LED serves mainly as an audio format indicator, and less so than a battery indicator: EarMen TR-amp is on (“white”), connected/PCM (“green”), MQA (“magenta”), DSD (cyan), charging (“flashing blue”), and low battery (“flashing red”). It is well visible while inconspicuous.

Rear Panel

The back panel sports two USB-C ports, a Pre Out/Direct switch, and RCA outputs.

One of the UBS-C outputs is used for charging, the other for data transfer. Both can be deployed simultaneously. When the EarMen TR-amp is connected to a computer, it is running on battery by default. You have to connect the other USB-C port to a USB-charger or external battery pack for charging.

The EarMen TR-amp’s amplifier function can be bypassed when connecting it to a (more powerful desktop) amplifier through the 2 RCA outputs. The switch serves the purpose of specifying the volume control. in the “Direct” position, the EarMen TR-amp’s volume knob is being disabled and the full-strength signal is being transferred through the”Line Out” into the external amp, which requires its own volume control. In the “Pre Out” position, the TR-amp’s volume control is activated.

Independent of the switch position both headphone outputs are always operative and two people can listen simultaneously.

AMPLIFICATION

The EarMen TR-amp works well with the Sennheiser HD 300 Ω impedance headphone (and therefore most on the market), but its 350 mW into 32 Ω would probably not drive more exotic 600 Ω headphones well. Power details in the specs above.

POWER CONSUMPTION/PLAY TIME

Ear Men claims up to 10 hrs of play time but does not give you specifics on the setup. I tested with the power-hungry Sennheiser HD 600 and iPhone 5S at a “normal” but pretty healthy volume level. After 6 h and 15 minutes, the indicator light started blinking, which means the the battery level and dropped below 20%. This points to 7-8 h playtime with this setting.

I value this as being in line with the manufacturer’s claims.

SOUND

My tonal preference and testing practice

My test tracks explained

Equipment used: EarMen TR-amp; Macbook Air, iPhone SE 1st gen.; Apple camera adapter, ddHifi TC28i adapter; Schiit Magni 2U headphone amplifier with Audioquest Forest and Snake Oil Taipan RCA interconnects; 300 Ω Sennheiser HD 600 headphone, 16 Ω Sennheiser IE 300 earphone.

The “ingredients” of the EarMen TR-amp are top notch, but how good is the “cooked meal”? Such a device works well with your phone on the go (if you like strapping it around it), but it can also be deployed as a desktop amp, and it can also be used as pre-amp or dac, when connected to a “bigger” dedicated headphone amplifier.

I tested the TR-amp in these scenarios:

1. …as dac-amp with MacBook plus headphones/earphones
2. …as dac-amp with phone
3. …as dac AND pre-amp with Schiit Magni 2 Uber, sourced by MacBook

The EarMen TR-amp, just like the Sparrow, produces a neutral sound with a tinge of warmth added to spare us from a clinical, lifeless, or overwhelming sonic reproduction. Straddling that thin line, it allows for harmonizing with both, neutral and warm headphones/earphones.

Extension towards both ends is very good and so are headroom, sense of space, and dynamics. The punch is natural and works with electronic, rock, and acoustic music such as symphony or jazz. The image has a good volume and body, it does neither sound lean or syrupy thick. The TR-amp preserves the music’s midrange clarity and brings vocals out intimately.

I also could never hear any noticeable hiss, not even with the sensitive 16 Ω Sennheiser IE 300. But it brought out the bassy side of these naturally bassy iems without muddying or congesting the sound.

It is really boring to report the sound of an amp that does not alter music and reproduces it as should be. The EarMen TR-amp simply works and has been for quite some time for me.

Using the EarMen TR-amp with as a pre-amp (“Pre-Out”) and dac (“Direct”) with the warmer Schiit amp adds a bit of colour and results in added power and heft. This is only valid for this particular setup . Sonic results will vary with different amps connected.

What I’d like to see is a gain switch for easier volume fine adjustments with sensitive earphones.

EARMEN TR-AMP COMPARED

I can only offer the $199 British nano iDSD Black Label (“BL”), which is a bit smaller and less powerful (285 mW vs. 350 mW @ 32Ω) – both feature a 3700 mAh battery. The BL does not drive the Sennheiser HD 600 as well as the TR-amp, but it has two 3.5 mm outputs, one of which (“IE Match“) offers increased output impedance for sensitive iems. The more powerful TR-amp is rather designed towards full-sized cans with its 6.3 mm output – whereas the BL caters more to the less power hungry peripherals…although both play both well.

The BL is warmer sounding and therefore more limited to the more neutral headphones/earphones, it may sound muffled with warm earphones/headphones. The EarMen TR-amp is more versatile in this respect. The BL has the choice of two audio filters, the TR-Amp does not. And the BL has a pseudo 3.5 mm balanced circuit.

In terms of connectivity, the EarMen TR-amp has a L and R line out, the BL has a single 3.5 mm line out. Both can be used as dacs, and only the EarMen as pre-amp. The TR-amp, with its separate UBC-C ports for charging and data can be charged while playing, the BL with its USB-A port can draw power from the source (“computer”) or run on battery, but it cannot play and charge simultaneously.

CONCLUDING REMARKS

The Earmen TR-amp has been playing everything I threw at it in the last few months, from sensitive iems to the 300 Ω Sennheiser HD 600. And it played them all very well. It is a robust classic design that feels and sounds good, that is powerful enough for almost anything, and that is reasonably priced. It simply works for me and don’t want to miss it.

What else can I say?

Until next time…keep on listening!

EXECUTIVE SUMMARY

The Khadas Tone2 Pro is an innovative miniature desktop dac with integrated headphone amplifier that offers a ton of functionality qualifying it as a competent “Jack of All Trades”.

INTRODUCTION

Khadas is a Shenzen company run by a team of audio enthusiasts. Their first release was the infamous “Toneboard”, a $99 dac/amp that came “naked” without housing. Much of the company’s inventory caters to electronics junkies with soldering skills.

DISTINCTIVE FEATURES OF THE KHADAS TONE2 PRO

The Khadas Ton2 ProPro is a miniature integrated dac-amp that works with Window and Mac computers as well as with Android and iOS devices. It shares certain features with traditional dongles such as the EarMen Sparrow or DragonFly Cobalt in that it is connected to a phone or computer via USB. But a dongle relies entirely on the power of its source and only outputs into 2.5 mm/3.5 mm/4.4 mm audio. The Khadas Tone2 Pro can be powered by its audio source or independently, and has more output options/possibilities than a dongle. It shows, however, less flexibility when connected to a phone because it needs an external power supply in this setup.

The Khadas Tone2 Pro’s distinctive features are:

• Unique encoder knob
• Flexible power supply options (source device or linear power supply)
• Balanced RCA connectors (cable available from Khadas; backwards compatible for connecting a single-ended headphone amp)
• Reversible S/PDIF coaxial input/output (for connecting a CD player or use as USB to coax converter)
• 4.4 mm balanced headphone socket (plus single-ended 3.5 mm socket)
• Add-on bluetooth module (still being developed)

SPECIFICATIONS

Khadas lists the Tone2 Pro’s full specs in every detail; they can be downloaded here. The most important ones are:

DAC chipset: ESS ES9038Q2M 32-Bit Stereo Mobile Audio DAC
Amplifier chipsets: I/V Stage: TI OPA1612 x2, LPF Stage: TI OPA1612 x2, Buffer Stage: RT6863D x3
Output Impedance: <0.3 Ω
SNR: 119-121 dB (depending on output)
Up to 32bit 384KHz sample rate, bit-perfect DSD512, and -118dB THD+N (line-out).
MQA decoding
Compatibility: Windows/Mac, Android, iOS

Maximum output, single-ended circuit (3.5 mm socket):

• 35.3 mW @ 150 Ω (2.0 Vrms)
• 125 mW @ 32 Ω (2.3 Vrms)
• 114 mW @ 16 Ω (1.35 Vrms)

Maximum output, balanced circuit (4.4 mm socket):

• 83 mW @ 300 Ω (5.0 Vrms)

PHYSICAL THINGS AND FUNCTIONALITY

In the box are the actual device, a USB-C to USB-C cable, and the manual. The very small Khadas Tone2 Pro ‘s enclosure and the encoder knob are made of aircraft grade aluminium, with a polycarbonate bottom cover on a soft silicone pad – in order not to scratch the underlying surface.

The manual is pretty confusing when it comes to setup with a computer (Mac is not mentioned at all but it worked just upon plugin), firmware update, and operation, but there are excellent videos available that offer all necessary solutions.

CONNECTIVITY: THE SKY’S YOUR LIMIT

The Khadas Tone2 Pro offers a variety of connections – and therefore a variety of usages.

Inputs: USB-C (computer/phone/raspberry-type single-board computer), I2S (linear power supply, bluetooth module), coaxial (CD-player).

Outputs: 3.5 mm and .4 mm “balanced” headphone sockets (can be used simultaneously), balanced RCA (backward compatible), and the coaxial can be reversed with a firmware change.

INTRODUCING BALANCED RCA

Khadas developed “balanced” RCA connectors which they implemented in their Tone2 Pro. You can connect balanced RCA cables and stream to a balanced amp. While this is a great idea, such cables do not exist yet, and other manufacturers have yet to embrace the balanced RCA technology (but Kadhas sell you a $40 balanced RCA to XLR adapter). No third-party amp with balanced RCA connectors exists presently. Good that these connectors are backward compatible – you can use your old RCA cables.

However, balance amps exist and in order to connete them with the Tone2 Pro, Khadas are selling RCA to XLR adapter. Problem solved…for now. But other manufacturers will have to embrace the balanced RCA technology for the technology to survive.

THE CRAZY VOLUME KNOB IS ALSO A JOYSTICK

Khadas introduce a hybrid digital/analog volume control knob that works like both a normal rotary knob and joystick.

You can turn it like a standard volume knob but also push it sideways…but you need to hold the light device with the other hand during operation…awkward when it is sitting on an amp. Typically each two lateral pushes cycle you through the different modes from volume through track forward/backward, gain, input selection, and digital filter. Here the overview of all modes (from the user manual):

In each mode, you rotate the knob to change the functions as indicated in this graphic. Any setting is visualized by a colour combination in the RGB ring light at the base of the knob. While it is painful to read is, you just watch these two videos to get the details:

PRACTICAL USE OF THE KHADAS TONE2 PRO

In real life, you can use the Khadas Tone2 Pro as follows, for example:

CD player/streamer/computer/tablet/phone –> Khadas Tone2 Pro –> headphone

CD player/streamer/computer/tablet/phone –> Khadas Tone2 Pro –> headphone amp –> headphone

CD player/streamer/computer/table/phone –> Khadas Tone2 Pro –> stereo amp –> loudspeakers

To give you some idea: I first connected the Khadas Tone2 Pro to my computer via USB-C and also used the computer as power source. This was just fine for listening to iems and even the 300 ohm Sennheiser HD 600. I then added power by connecting the Schiit Magni 2 Uber headphone amp via RCA cables. The Khadas Tone2 Pro now served as pre-amp.

I then moved to my stereo system and connected the Khadas Tone2 Pro to my CD player via coaxial RCA. I also connected my phone to the Khadas Tone2 Pro’s USB-C port…and had two music input sources to choose from. I switched between the sources using the rotary function of the dial after having it set to “Input” mode….and listened to CDs with my Sennheiser HD 600 connected to the Khadas Tone2 Pro 3.5 mm socket. I now had to option to use the RCA out to connect the Khadas Tone2 Pro either to a headphone amp or to the stereo’s power amp.

Streaming music from your phone to the Khadas Tone2 Pro via Bluetooth would be an interesting asset. This functionality has not been implemented yet – a add-on Bluetooth module is presently being developed.

SUPPLIED POWER VS POWER SUPPLY

The Khadas Tone2 Pro is driven from the USB-port of your computer without problems. I was told that a notebook is an electrical firestorm and that there is some electrical noise associated with Mains power at 20, 60, and 180 Hz on laptop USB.

The Khadas Tone2 Pro features a second USB-C port (labelled I2S), designed for input from a Linear [Voltage] Power Supply (“LPS”). An LPS supplies a constant current, which minimizes electrical noise and generates ultra-clean signal-to-noise ratios. But I was warned that the “wrong” LPS could make the Khadas Tone2 Pro (and similare devices) “dull and uninspiring” sounding. When in use, I2S prioritizes the LPS over the USB source. Separating data flow and power, and supplying power from a “clean” LPS serves the purpose of improving sound quality. This is particularly important when the Khadas Tone2 Pro is used as dac. Any distortion/impurity in the signal will be exaggerated by the attached power amplifier.

And while an LPS may feed the Khadas Tone2 Pro with “clean” power, this also opens a can or worms.

First, an LPS is expensive. At a minimum, you spend 40% of the Khadas Tone2 Pro’s purchasing price – when you live in North America. In Europe, a quality LPS sets you back 120 EUR. And even if you convert your old microwave into an LPS, it takes $50 in parts. This is cost prohibitive.

Second, these LPS are bulky and heavy, which is contradicting the idea of the Khadas Tone2 Pro’s lightweight and small dimensions. This is less of an issue when don’t locate the LPS on your desk but use it as a kick plate underneath.

Third, the music coming out of the computer’s USB port will still carry impurities.

Khadas failed to design an affordable LPS as an add-on, which I consider a flaw considering all the good ideas that went into the Tone2 Pro. After all, the buyer wants a perfectly functional device out of the box.

So, what are the alternatives? After all, any dac or amp comes with its own power supply – and you don’t have to worry about it – and therefore not pay extra through your nose. I tested a $15 powerbank (stable power supply), Apple stock 5 V chargers for iPhone and ipad (all switched-mode power supplies but of good quality), and two low-noise power supplies provided by ifi Audio (for a separate review). The potential issue with switching currents is electrical noise being introduced to the signal.

First of all, all of the above principally powered the Khadas Tone2 Pro. So the question is whether LPSs are overkill. We will answer this question below.

SOUND IN DIFFERENT APPLICATIONS

My tonal preference and testing practice

My test tracks explained

Equipment used: MacBook Air, iPhone SE (first generation), Marantz SACD8005; Khadas Tone2 Pro, Schiit Magni 2U; KBEAR TRI I3, Shozy Form 1.4, Sennheiser HD 25 and HD 600; ddHifi adapters DJ35AG/DJ44AG; diverse power supplies (ifi Audio iPower & iPower X, Apple iPad 12 W switching power supply, Tzumi 10,000 mAh power bank); Snake Oil Taipan and Radio Shack RCA interconnects; Amazon basics coaxial RCA cable.

Setup 1: Khadas Tone2 Pro with MacBook Air and TRI3 and Shozy Form 1.4 earphones with DJ35AG/DJ44AG adapters

This test served the purpose of comparing the single-ended and balanced circuits using 2.5 mm balanced cables and the DJ35AG/DJ44AG adapters. I used the easily driven Shozy Form 1.4 and the harder-to-drive planar magnetic TRI3 earphones, both on low gain.

The balanced circuit was much superior over the single-ended one in that the sonic experience was much more three dimensional and atmospheric, with a much better spatial cues, more note weight…and it was simply louder. The technicalities were all quite good with one downside: the timbre was rather digital and a bit edgy for the cello sonatas I had started my test off with…and the sound was lively and crisp with rock music, though the bass could have been a bit meatier.

I mentioned it above: both outputs work simultaneously…two can listen.

Setup 2: MacBookAir with Khadas Tone2 Pro and Sennheiser HD 600 headphones

I could only test the “weaker” 3.5 mm single-ended output with the 300 Ω Sennheiser HD 600 headphones…and I was pushing the Khadas Tone2 PRO’s limits (on high gain). I achieved an astounding headroom considering this small device, although the dynamics stayed on the “polite” side. This combination principally worked, but it had reached its limit. I would not push any harder-to-drive headphones.

Setup 3: Marantz SACD8005 with Khadas Tone2 Pro and Sennheiser HD 600 headphone

This experiment served testing the coaxial input from the CD player with uncompressed music. I used a $12 CAD amazon basics coaxial cable that is surprisingly well made. The SACD has its own integrated headphone amplifier so I could A/B from the same source.

This combination sounded quite impressive with lots of headroom and transparency. In comparison, the integrated Marantz headphone amplifier (with unknown but probably high output impedance) sounded somewhat muffled with less extension.

Setup 4: MacBook Air with Khadas Pro into Schiit Magni 2 Uber and Sennheiser HD 600/HD25 headphones

In this setup, the Khadas Tone2 Pro was only used as a dac, with the Schiit as the amp. And it literally rocked. The punch returned to the Senns and so did naturalness. Yes, this combination sounded more natural than the Khadas’s integrated amplifier. Switching from the 300 Ω HD 600 to the 70 Ω HD 25 added some lightness and ease…but this probably has to do with the Schiit’s limited output rather than the T2 Pro.

I also played with cables and compared the sturdy Snake Oil Taipan interconnects (with their German Sommer wire) with some 20-year-old Radio Shack ones. And, compared to the Radio Shack ones, the Snake Oil added…no, not snake oil, but bass, as if a subwoofer had been added. Which one is better comes down to personal taste.

I then replaced the Khadas Tone2 Pro with the Dragonfly Cobalt as dac, which also sounded great but slightly less substantial. This probably lies in the quality of Khadas’s dedicated RCA outputs.

And what did the different power supplies contribute?

I tested the Khadas Pro with the different power supplies (ifi Audio iPower/iPower X, Apple iPad 12W switching supply, Tzumi power bank, Macbook’s USB power), musically sourced by the MacBook. Since the Khadas prioritizes the I2P port (it switches automatically when an external power source is connected), A/B-ing was easy.

What did I expect between Mac power and external power? From discussions and company advertisements/claims, the electric noises should should have been decreased – and the sonic impact should have increased with an external low-noise supply.

What differences did I hear? Absolutely none, zero, zilch. This relates to the Mac as the music source while using the Khadas as amp and as dac in combination with the Schiit amp. I would have expected this for integrated amp, but additionally amplifying the signal with the Schiit should also have further amplified the noise.

I also alternated the external power supplies when playing music from the Marantz SACD player…and could also not hear any differences between them. But I noticed an excellent clarity and headroom, which probably reflected the uncompressed nature of the music compared to the compressed formats on the Mac.

In the end, there were too many unknowns to allow for a conclusive answer on the LPS question other than that an external power supply likely does not make the world or a difference. The cheap compromise would be the power bank.

Talking to audio engineer Amir from Audio Science Reviews (who had also reviewed the Khadas Tone2 Pro), he told me that different power supplies can make a small measurable difference, which are not significant enough to justify their purchase. The Khadas Tone2 Pro’s performance is superb without.

I don’t object.

CONCLUDING REMARKS

The Khadas Tone2 Pro is not only a “Jack of all trades”, it is also a master of many. It incorporates a lot interesting concepts and innovations – and it works by itself or in combination with essentially anything. It has come a long way from the original “naked” Toneboard for the DIY person to this turnkey device that will provide users with lots of fun…after an initial learning curve. A unique product that is uniquely good.

INTRODUCTION

I love adapters. Yes, you are reading correctly. I have boxes of them…see photo at the bottom. But when I recently received a couple of German premium earphone review loaners with a combined worth exceeding $5000, they came with an adapter. And guess wh

at, it was a ddHifi branded one. A Chinese adapter on a German premium earphone cable? Must be of good quality. And it was. In fact it worked so well that I purchased three versions of it way before I received the actual two units for this review.

One of them, the ddHifi TC25i let’s one connect a 2.5 mm mm balanced cable to an iPhone’s lightning port. The other one, ddHifi TCI28i, turns the iPhone’s lightning adapter into a USB-C port. I will explain the practicality of these devices in the following – also get some idea from the images throughout and at the bottom of this article.

SPECIFICATIONS TC28i

• Input: Lighting

• Material: Aluminum alloy
• Dimensions: 0.7 x 0.4 x 0.5 in (18.5 x 9.5 x 13.5 mm)
• Tested at: $30
• Product page: ddHifi

PHYSICAL THINGS AND USABILITY/FEATURES

The TC25i and TC28i are robust, sturdy, small, and light – and made of metal. Build and haptic are excellent.

What do these adapter do? I’ll discuss this as follows. Note: the reviewed versions will only work with iPhones and iPads, even if these devices are mantled with the thickest possible cases. And – in order to give you some idea what these adapters can be used for, I appended a set of images of my own applications below.

TC25i Lightning to 2.5mm Headphone Adapter: is essentially the equivalent to the Apple lightning audio adapter (which I reviewed in great detail), but with a 2.5 mm output. Although all 2.5 mm cables are “balanced”, the TCi25 is not. Its sister adapter TC35i features a 3.5 mm adapter and serves the same purpose as the Apple lightning adapter.

The TCi25i/TC35i have a lot of technology packed into that small enclosure: a microscopic stereo digital-to-analog converter (DAC), a stereo headphone amplifier, a microphone preamplifier, and monophonic analog-to-digital converter (ADC) – and power converters to run this all.

Considering that any connector is a sonic bottleneck and that the wire in the Apple Audio adapter is the limiting factor for any premium cable, cable aficionados are better off with the TCi25.

TC28i Lightning to USB Type C Adapter: is simply a connector for dongles. It essentially serves the purpose of the Apple lightning camera adapter. When connecting your iPhone to a dongle via the Apple adapter, you create a rather long chain. The TC28i shortens this “snake” and makes it more portable.

There is a big difference, however, between Apple and ddHifi in that the former has the traditional USB-A connector whereas the ddHifi TC28i features the smaller USB-C connector.

This is no problem as most dongles come with either connectivity. And if everything fails, there are cheap USB-C to USB-A connectors.

TONALITY AND TECHNICALITIES OF THE TCI25i

First test of the ddHifi TC25i lightning to 2.5 mm adapter against the iPhone 5S’s internal dac/amp (which is essentially identical to the Apple audio adapter for later iPhones).

The iPhone 5S is a formidable audio player: https://www.kenrockwell.com/…/iphone-5s-audio-quality.htm. Result: no noticeable difference found in terms of sound quality and amplification power.

So what does the TC25i sound like? I agree with the Headphone Collector also analyzed the Apple audio adapter [here]…as said, the ddHifi TC25i sounds essentially identical . He writes: “…Neutral, clear, clean and very precise. Basically as audibly transparent, good-sounding and clean-sounding to my ears as it gets. Precise and tight bass reproduction with sensitive multi-BA in-ears.

VALUE

TC25i Lightning to 2.5mm Headphone Adapter, although identical sounding as the Apple Lightning Adapter, may appear expensive at four times the price.

But: Apple does not offer a 2.5 mm adapter and their dongle is plastic/rubber with a cable that is prone to fray. The TC25i is made of metal (and has therefore the much better haptic and durability), is much less conspicuous because of its smaller size, and is extremely practical as you don’t have to earphone change cables when switching between devices.

It is also classy compared to the Apple. And it is particularly useful when deploying cables with the unreliable MMCX connectors. It may save you money in the long run by not ripping your MMCX connectors apart.

The TC28i Lightning to Type C Adapter costs about the same as the Apple camera adapter. Again, the ddHifi product is smaller, more rugged, and has the better haptic. The difference between the two – that is USB-A for the Apples and USB-C for the ddHifi – is somewhat unimportant as most peripherals come with both-type cables – and if not, there are cheap quality adapters, the best from UGREEN.

CONCLUDING REMARKS

I love adapters and the ddHifi adapters are on top of my list. They are high-quality and therefore good enough to be used with the most premium equipment, they look and feel good, they are priced right, and they are extremely practical.

While these two units had been provided by dHifi, I purchased other ddHifi adapters for my pleasure so impressed was I. You will see ddHifi adapters all over this blog. Check it out for yourself:

EXECUTIVE SUMMARY

The Tempotec Sonata BHD is a neutral, sleek, crisp, and transparent sounding 2.5 mm balanced dac/amp that offers a substantial sonic update over phone/computer dacs/amps when used with iems. One of my favourite products in 2021. A personal favourite.

NOTE

I did not test the Sonata BHD with headphones owing to the lack of a balanced cable. Considering its power, the Sonata BHD is much better suited for iems. I also did not test DSD and MQA, as I do not have the required subscriptions. And I think the Sonata BHD is more tailored towards mobile units than towards computers.

INTRODUCTION

Chinese manufacturer Tempotec made quite a dent with their Sonata HD Pro in 2019. At $40, it comes with all possible adapters and you can connect it to essentially everything: Android devices, Apple devices, and computers. Not bad at the price of essentially an Apple lightning adapter. Unsurprisingly, the Sonata HD Pro has been a favourite in terms of audioreviews.org blog views since, made it into my “Gear of the Year 2020“, and remains highly recommended.

The Tempotec Sonata HD Pro features a single-ended output, whereas, in the meantime, companies like Earmen offer two outputs in their Sparrow dongle: 3.5 mm single-ended, and 2.5 mm balanced. And while I thought “balanced” was just another gimmick, it is truly not: everything sounds bigger and clearer with balanced in a direct comparison. But the Earmen Sparrow comes at a price of $200. Tempotec responded to the market’s demand for “balanced” output with their Sonata BHD, a sleek and powerful dongle at $70.

To answer you burning questions right away: does the Sonata BHD sound better than the Sonata HD Pro? Yes, it does. Does it sound as good as the Earmen Sparrow? No, not quite, but it still sounds impressive.

THE IDEA OF BALANCED AUDIO

Balanced audio is a method of connecting audio equipment using balanced lines [Wikipedia]. Such lines reduce susceptibility to external noise caused by electromagnetic interference. This is particularly beneficial for recording studios, which use kilometres of lines. For our purpose of portable audio, reduced interference results in a clearer, cleaner signal. Headphonesty compared “balanced and unbalanced” audio connections in this article.

PHYSICAL THINGS AND USABILITY

The Sonata BHD comes with a fixed USB-C cable, a USB-C female to USB-A adapter, and a pleather case. It does not feature the detachable cables of the Tempotec Sonata HD and is aiming to be connected to USB-C and USB-A devices such as Android phones, and Windows and Mac computers. It can be connected to iPhones/iPads using either the Apple camera adapter or the much sleeker ddHifi TC28i adapter. Therefore, adding a third-party adapter makes the Sonata BHD as versatile as the Sonata HD Pro with source devices.

In terms of dimensions, the Sonata BHD is slimmer and higher than most dongles. And like the Sonata HD Pro, the housing is made of metal with rather sharp corners. Tempotec increased the often criticized spacing between the two volume buttons compared to the Sonata HD Pro – what they have not addressed is the volume steps when pushing the buttons (which are identical to the source’s volume buttons). The button mechanism is exquisite and precise – with a great soft rebound – so that is is almost fun pushing them. All connections and connectors work precisely, too.

Internally, the Sonata BHD features the same chip as the Sonata HD Pro, however TWO of them (one for each line), which explains the price difference.

FUNCTIONALITY

The Tempotec Sonata BHD has no internal battery and is driven by the music source. This is great in that there is no planned obsolescence (the device will still work in, let’s say, 10 years), but it drains your mobile source faster. As to the drain rate, I did not explicitly test it – but battery consumption appeared to be within reason.

The Sonata BHD is plug ‘n’ play with phones and tablets, and it requires selecting the device in my Mac’s sound panel (probably similar in Windows).

When playing, the Sonata BHD relies on the source volume. I typically set the computer/phone volume at 80%, although I am not sure whether I can turn it up to 100% without (more) distortion. After removing the Sonata BHD from my phone, it recognizes the volume setting upon reconnecting.

AMPLIFICATION

There is a paradox: a balanced output is typically more powerful than a single-ended output – and iems, on average, require less power than headphones: however balanced cables for headphones are harder to get and more expensive than for earphones. As a rule of thumb, external amplification is needed for headphones/iems with an impedance above 50 Ω. While most headphones exceed this number, most iems run at 32 Ω or lower. Iems above 50 Ω typically feature electrostatic or piezoelectric drivers. I don’t have any balanced-headphone cables but could test the Sonata BHD with power-hungry iems such as the Vision Ears Elysium, Triaudio I3, and NiceHCK NX7 Mk3. And they were all driven very well by the Sonata BHD.

I could not test the Sonata BHD with headphones – I don’t have one with a 2.5 mm cable – but was told it is not that powerful. I would therefore be careful with any headphone above an impedance of 70 Ω.

As to specs, the Sonata BHD delivers 120 mW into 32 Ω (and 20 mW into 600 Ω). This is twice as much as the original Sonata HD Pro offers.

TONALITY AND TECHNICALITIES

My tonal preference and testing practice

My test tracks explained

Equipment used: iPhone SE (1st generation) and MacBook Air; various earphones, mainly the Shozy Form 1.4.

The Tempotec Sonata BHD is a strictly neutral and sleek but never sterile or over-analytical sounding dac/amp that enhances the sound characteristics of the attached earphone/headphone. It is not only useful for running power-hungry earphone/headphones, it also improves the sound of easy-to-drive iems. Let’s take, for example, the excellent sounding, well reviewed Apple Audio Adapter that works well with my 16 Ω Shozy Form 1.4 iems. The Tempotec Sonata BHD simply adds midrange clarity and definition, opens up the soundstage, and increases headroom. And it adds pizaz to the sound…yep, it is rather punchy. These improvements over my phone are quite pronounced – and much bigger than with the Tempotec Sonata HD Pro.

Replacing the Tempotec HD Pro with the Tempotec Sonata BHD is like adding sour cream to your gravy: smoother, better balance, much bigger stage, better three-dimensionality, the sound is simply more appealing. Connecting my >50 Ω earphones added body, cleanliness, and smoothness on top of power.

WHO NEEDS THE SONATA BHD?

IMO, the Sonata BHD serves two specific purposes:

• Play power hungry iems (such with an impedance of > 50 ohm)
• Improve the sound quality of any iem, even at low volumes

First, there should be no problem playing a, let’s say, 70 Ω headphone such as the Sennheiser HD 25 with the Sonata, however it may be cost prohibitive to get a 2.5 mm balanced cable for headphones. Second, the Sonata BHD is not an ornament as so many other dongles. Any earphone sounds better on my iphone with the Sonata BHD compared to the Apple Audio Adapter or the ddHifi TC25i adapter (which is technically and sonically essentially identical with the Apple Audio Adapter). In comparison, the Sonata BHD adds clarity and definition, slims down the sound, and opens up the stage including headroom.

But I doubt that you will be able to drive full-sized 300 Ω cans with the Sonata BHD well.

TEMPOTEC SONATA BHD COMPARED

As said before, the Tempotec Sonata BHD upgrades the sound of the Apple Audio Adapter as well as their own Tempotec Sonata HD single-ended dongle. It does, however, not live up to the balanced circuit of the $200 EarMen Sparrow that excels in its more analog, fuller sound with an even better headroom. Nevertheless do I like both for their merits and one cannot replace the other. Similar to the different models in my earphone collection, both dongles hits different moods of the listener and I really enjoy them both very much.

CONCLUDING REMARKS

The Sonata BHD provides a huge sonic upgrade to your phone and is another winner from Tempotec. Is sounds better and is more powerful than their famous Sonata HD Pro, but is a bit more limited by its ootb connectivity. Adding a second dac chip has increased the price, which benefits the sound greatly. The Sonata BHD is not only good for amplification but also for improved the sound quality of easy-to-drive earphones and headphones. It is not an ornament as so many others. Once again, a superb device and great bang for your buck. As simple as that…I said it before.

Until next time…keep on listening!

The post Tempotec Sonata BHD Headphone Amplifier (Dual CS43131 Balanced Output) Review – Snakebite appeared first on Audio Reviews.

EXECUTIVE SUMMARY

The EarMen Sparrow is a $200 battery-less warm-neutral sounding dac/amp with dual output: single ended 3.5mm and the more powerful 2.5 mm balanced. It is class leading in terms of both power and sound quality. The EarMen Sparrow supports playback from iPhones, Android smartphones, MacOS and Windows computers. It also plays all 32bit/384kHz formats: PCM, DoP, DSD64, DSD128 and MQA. It is the best dongle I have come across (in the $200 category) and was on my personal favourite gear list of 2020.

INTRODUCTION

Do all dongles sound equal? Are most dongles just ornaments? Should we rather go for a desktop dac/amp instead to get more value for money? All of the above have been mentioned in discussions lately. For years I have had a single dongle dac/amp, the Audioquest Dragonfly Black. I mainly used it with my iPhone and life was good. Until…

To make this clear a priori: the EarMen Sparrow is the best-sounding dongle I have tested too far…but also the most expensive one. And it is not an ornament.

EarMen is a company registered in in the US, where most of its stakeholders are located – and from where they focus on the North American market. EarMen are a subdivision of premium audio gear producer Auris Audio. The production is in Krusavec, Serbia [video of production facilities]: Made in Europe.

SPECIFICATIONS

Dimensions: 42*22*8 mm

Purchase Link: EarMen Shop

PHYSICAL THINGS AND USABILITY

In the box is the EarMen Sparrow, the warranty card, and two cables: USB-C to USB-C, and USB-C to USB-A. This allows the Sparrow to connect to Android phones/tablets, and any Windows/Mac computer. It features the ESS Sabre ES9281PRO dac chip – which is well implemented.

The EarMen Sparrow also works with iOS devices but requires the Apple Camera Adapter, which adds to a “monster snake”. The $30 ddHifi TC28i adapter offers the same funcionality but cuts the snake’s length enormously.

The actual EarMen Sparrow is a sturdy and filigree CnC machined aluminium construction with top and bottom covered by glass…although I wished it had come with a sheath to protect it from being scratched.

In contrast to most other dongles does the EarMen Sparrow offers two different circuits and sockets: a single-ended output through a standard 3.5 mm socket and a balanced output through a 2.5 mm socket. Both outputs/sockets work simultaneously. And it is the balanced output that makes the EarMen Sparrow particularly attractive.

THE IDEA OF BALANCED AUDIO 

Balanced audio is a method of connecting audio equipment using balanced lines [Wikipedia]. Such lines reduce susceptibility to external noise caused by electromagnetic interference. This is particularly beneficial for recording studios, which use kilometres of lines. For our purpose of portable audio, reduced interference results in a clearer, cleaner signal. Headphonesty compared “balanced and unbalanced” audio connections in this article. And yes, it works.

FUNCTIONALITY

The EarMen Sparrow contains no battery and is powered by the source device. It works plug ‘n’ play with computers, tablets, and phones (Windows/Mac/Android/iOS). And it requires adjusting the respective sound panel settings in Mac and Windows computers. Volume is controlled from the source device – there are no buttons on the EarMen Sparrow. It is as easy as that. The EarMen Sparrow decodes all 32bit/384kHz formats: PCM, DoP, DSD64, DSD128 and MQA. 

AMPLIFICATION

The EarMen Sparrow is one of the most powerful dongle dac/amps on the market according to AudioScienceReviews.com. Its 2.5 mm balanced output delivers 2.0 Vrms into 32 Ω and 4.0 Vrms into 600 Ω. This results in a power of 125 mW and 20 mW, respectively. The 3.5 mm single-ended output is 1.4 Vrms into 32 Ω and 2.0 Vrms into 600 Ω, which translates to 61 mW and 7 mW, respectively.

I don’t have a balanced cable for my 300 Ω Sennheiser HD 600 Pro, however the single-ended output drives them “ok”. The balanced circuit delivers enough power to drive the 70 Ω Sennheiser HD 25 on my Mac, which indicates that this is good enough for any iem. In fact, imo the EarMen Sparrow drives even the most power-hungry earphones very well with my Mac.

A bit of an enigma is the dependency of the EarMen Sparrow on my sources: it provides way more power when sourced by my Mac, but appears to be throttled by my iPhones 5s and SE (1st generation). I speculate this is caused by the Sparrow’s power consumption. Sound quality is not compromised and power-hungry earphones such as the TRI I3 are still driven sufficiently well. Newer phones and Android devices may not throttle the EarMen Sparrow’s power. The Sparrow, like most powerful dongles, appears to be a bit of a battery drain on phones.

UPDATE June 2021: Power Consumption Test: Parameters and Raw Results

I tested the power consumption of several portable headphone amps connected to my iPhone 5S. The conditions were as identical as possible: 3 h test, volume calibrated to 85 dB  ± 0.5 dB white noise with Dayton microphone, no sim card, BT off, no other apps open; network on, 32 ohm Blon BL-03 iem, Genesis’s Supper’s Ready (from the Seconds Out album) played in an endless loop.

The iPhone’s battery was fully charged at the start of the test and the remaining charge was measured thereafter. The result is shown in the table below. Since the tests were performed at different times and considering the ongoing battery deterioration, the results have to be seen with a grain of salt.

TONALITY AND TECHNICALITIES

My tonal preference and testing practice

My test tracks explained

The EarMen Sparrow is a neutral-warm sounding dac/amp (more neutral than warm), and therefore offers the best of both worlds. Whereas a warm dac/amp (such as ifi Audio products) harmonizes best with neutral earphones/headphones (e.g. JVC HA-FDX1, neutral amps (e.g. Earstudio HUD 100) pair best with warm iems (e.g. Sennheiser IE PRO series). Neutral amp with neutral iem may sound like metal on metal – and warm with warm may come across as thick and syrupy lacking clarity and transparency. The EarMen Sparrow appears to strike the right temperature balance to harmonize with most kinds of earphones. The other trait is its good extension in both directions and its full body and natural dynamics. The Sparrow has this quasi-analog sound.

And while the sound through the single-ended output is good, it is fantastic through the balanced output. The difference in sound quality is mindboggling (I A/B-ed a balanced cable between both sockets – with a 2.5 mm female to 3.5 mm male adapter for single ended). Apart from the power gain in the balanced circuit, headroom and clarity opens up substantially…the midrange comes out nicely…this worked even for the ~$3000 Vision Ears Elysium. After several months of using the EarMen Sparrow on my Mac, I conclude that the balanced output is as good as a desktop amp for iems – on a computer.

EARMEN SPARROW COMPARED

The neutral sounding $70 Tempotec Sonata BHD dac/amp with its balanced output is an impressive sounding device. The EarMen Sparrow, however, offers a richer, more analog sound, a larger headroom, and more power. It is also more versatile with its additional 3.5 mm single-ended output. The less powerful Sonata BHD has a leaner, sleeker but less creamy/soft/weighty sound with more clarity.

VALUE – IS THE EARMEN SPARROW FOR YOU?

Is the EarMen Sparrow worth its $200? Any answer has to be subjective. For people who regularly deal with >$300 earphones without blinking: yes, no questions asked. Simply makes them sound better.

For the rest of us: yes, but for any or all of these three specific purposes – from my perspective: for the balanced output that sets the EarMen Sparrow sonically and power wise apart from its competition. Second, it is best used with iems or less power-demanding headphones. And third, for use mainly with a computer, where the Sparrow flexes its muscles best.

CONCLUDING REMARKS

I have used the EarMen Sparrow for a few months now. It took me so long to publish my review because I didn’t know what to write – it just worked great for me, and I used it a lot for earphone testing. The Sparrow is the best sounding dongle I have listened to so far (up to $200), albeit also the most expensive.

What sets it apart from the competition are sound quality and power of its balanced circuit. I don’t think one needs anything “bigger” to drive earphones – it was good enough for the $3000 Vision Ears Elysium. And since it does not have a battery, there is no planned obsolescence – the Sparrow will last for a long long time.

It is the balanced output that makes the Sparrow fly high: first it opens up the headroom and then it makes it a most powerful dongle – ahead of the competition. The EarMen Sparrow is just a very fine dac/amp. One of my favourite devices of 2020…and likely 2021, also. Basta!

Until next time…keep on listening!

Earphones

$300 – 500 USD:
LZ A7. Provides a mind boggling 10 tuning configs (or more with aftermarket tuning nozzles). It has excellent technicalities, good fit, good isolation, and the best part that surprised me is that the LZ A7 has very natural timbre for a BA/piezo containing tribid (other than the higher treble frequencies handled by the piezo). Most folks would find an ideal sound signature with it, maybe except diehard bassheads. 

$200 – 300 USD:
Audiosense T800. It has good technicalities, is “fun sounding” and excellent isolation nearing 30 dB. Even though it contains a BA bass, it sounds like a DD bass due to a vented subwoofer. The T800 may be a bit on the bright side, so it isn’t the best option for treble sensitive folks, but you can use knowles filters, warm sources or eartips to tame the treble.

@ $100 – 200 USD:
TRI I3. Smooth, balanced, grand and coherent despite the weird 1 planar + 1 BA + 1 DD config. It needs amping though, the planars handling the mids are quite power hungry. It has one of the best soundstages at the $100ish region when amped, with sweet planar mids. Treble is safe, bordering on darkish, so maybe not for trebleheads.

KBEAR BElieve. “Bearly believable” for a full beryllium set at this price? The KBEAR BElieve sports a smooth and refined U shaped tuning, great technical chops in the mids and treble areas for a single DD. It has good timbre for acoustic instruments but is very hard to drive, as per the 98 dB sensitivity. It sounds muddy, congested and slow in the bass with a low powered source, but scales beautifully when optimally amped, so those that don’t intend to get an amp best look elsewhere. With power, the KBEAR BElieve does hit about 70% of the technical performance of the famed DUNU LUNA, at 10% of the price! 

@ Sub $100 USD:
HZSound Heart Mirror. Nice mirror like shells, as per its namesake, it is a neutralish bright set, excellent timbre for acoustic instruments. I like how it manages to get a forward upper mids without going into harsh or shouty territory, a very fine line to balance. The Heart Mirror has good transients and speed on the driver. Note weight is thin and soundstage is not the best though, and it needs amping to shine, sounds meh from a smartphone. Good set for vocal lovers and timbre lovers, but maybe not so all rounded due to the lack of bass, but it takes to EQ in the bass like a champ.

Favourite earbud for the year:
SMABAT ST105 Black Gold. Neutralish set with subbass and upper mids boost. If you have always looked down on earbuds for not having subbass, think again. The SMABAT ST10S Black Gold has the best subass quantity and extension I’ve ever heard in a bud. It has excellent technicalities, is MMCX
detachable and can be worn over ears or cable down. It needs amping though, as per the 150 ohm impedance. Not to be mixed up with the SMABAT ST10S Black Silver, which is tuned differently (and has lower impedance).

Best lucky bag/Fukubukuro/Mystery bag:
Urbanfun YBF-ISS014 – it is extremely exciting to see whether u get a beryllium vs “noble metal” driver. Or a working versus wonky mmcx. Even newer batches of the Urbanfun have been reported to have QC problems in the audio forums.The Urbanfun can be summed up in this statement by Forrest Gump: “My Mom Always Said Life Was Like A Box Of Urbanfuns. You Never Know What You’re Gonna Get.”

Best price to peformance joke IEM of the year:
TRN golden ears $14,750.00 USD IEM paired with $3400 USD xiaofan ortiz “king of the gods” cable. Mere mortals cannot hope to use these gear if not you’ll be struck down by lightning! I hope the Bellsing BAs inside are also made of gold!

Biodegraded…Vancouver, Canada

Sorry, from me you get stuff that mostly hasn’t been reviewed. In no particular order; and most aren’t new this year.

Digital transports:
Pi2Design Pi2AES (+ Raspberry Pi)
For streaming (via wifi or Ethernet cable) digital music from your computer, you could go cheap and crap like a Chromecast or Airport, brutally expensive like an all-in-one streamer from Naim or PS Audio, or this $US 149 HAT for a Raspberry Pi which will produce excellent quality AES or S/PDIF digital audio to feed into your audiophile DAC. DIY aesthetic & philosophy, audiophile quality, fantastic convenience once you figure out how to set it up (variety of OS solutions, some better than others).

Amps/Preamps:
Ifi Audio Zen Phono RIAA phono preamp
$US 149 for excellent resolution and transients and the ability to work with a wide range of cartridges. Might benefit from an improved power supply such as Ifi’s own iPower, but my jury remains out on that. Audioreviews summary here.

Amp accessories:
GE JAN 5670W vacuum tube
Cheap and widely available true new-old-stock military-surplus tube that works really well as a 6DJ8/6922 preamp tube substitute (great in the Schiit Vali 2).  Nice tight lows, smooth but detailed mids, sparkly highs. 6922 to 5670 adapter required to translate the I/O pin pattern so nothing blows up.

Headphone accessories:
Yaxi pads for Porta Pro / KSC75 / PX-100
Tastefully boost bass and treble while (on the Kosses) lowering the prominent 5kHz peak. And they’re comfortable! Audioreviews summary here.

IEMs:
Drop/JVC HA-FDX1
Champion single-dynamic earphone with great DD timbre and almost BA-fast transients. Slightly boosted in the uppermost mids, heavy in the ears, intermittent availability, but huge bang-for-buck. Audioreviews summaries here and here (note that Loomis isn’t their greatest fan).

Headphones:
Fostex T50RP Mk3 with cheap angled pads and other mods
Closed or semi-open (depending on how much you stuff the cups) planar magnetic phones that with a little effort (see eg here for ideas) can be made both neutral and extended while retaining deep bass and technicalities. Need amp power to perform.

Players:
USB Audio Player Pro
Gets better with every update. Neutron is more configurable, but unnecessarily so. Put this on your Android phone, plug in a USB DAC/amp, and enjoy great lossless sound quality on the go. Equalizer plugins available. Android only though.

Durwood…Chicago, USA

CCA this year might as well been a lump of coal, it’s only two letters shy of selling your soul. If you want to talk to your boring Uncle Bob, (no offense Bob’s of the world) get yourself an iBasso IT00 or Tin Hifi T2 Plus you knob. Your uncle Bob is the guy who has lots of interesting things to say, but leaves you wondering what did you just listen to today. My only favorites this year were TRN STM who is the punk that your family doesn’t like to talk about and the Shozy Rouge as your killer looking date that likes to party but not shout. Waiting to see if Shozy Form 1.4 is in good form, only thing I decided to buy during the holiday sales storm. BQEYZ Spring 2 was a nice lively upgrade to the BQEYZ Spring 1, but fix that bass man, maybe take some lessons from the Nicehck NX7 Daniel son. Some of my friends from last year are still good folks to have around, Sony MH755, BLON BL03 for sleeping, and TinHifi T4 (I just wish you would hang in my ear longer than a few minutes of sound). Simgot EN700 is a carry over as well. I like a mild V if you can see.

Jürgen Kraus…Calgary, Canada

Blon BL-05s: These are very articulate playing single DDs also appeal to me through their hideous colour. Probably my most used items of the year (together with the JVCs and Shozy Form 1.4 below). Following the footsteps of the popular Blon Bl-03 – the Blon Bl-05s disappeared fast in the big black hole of anti-hype. And for a good reason: they look like the Bl-05, smell like the Bl-05, measure like the Bl-05, but the Bl-05 had been thrown on the market prematurely, and they sucked. The more distinguished audience may have realized that Bl-05 and Bl-05s have different drivers and sound completely different.

Drop JVC HA-FDX01: Hailed as arguably the best single DD on the market until Dunu Luna and Final Audio A8000 took over, this labour of love was originally only available 665 times….which has extended to above 2000 by now while the price dropped to $200. Carryover from 2019. Still my best earphones because of their organic timbre and great resolution.

TRI I3: Planar magnetic. Something totally different. Big and bold sounding yet soothing. Nothing offensive, nothing dull.

Sennheiser IE 400 PRO ($349): The best of their PRO series. Classic Sennheiser quality midrange. Super ergonomics. Nobody will dislike this one.

Shozy Form 1.4 ($199): The Shozy team somehow got their tuning 100% right. The Form 1.4 simply sound appealing to my ears…warm and fuzzy.

Guilty Pleasure: I pull the $70 FiiO FD1 out for the road: nice’n’punchy.

Vision Ears Elysium in the Endgame category. At 2500 EUR hand made by elfs and some Rhine mermaids in Cologne, out of reach for longer than a week (borrowed). Produce vocals better than real life but also melts credit cards. Cymbals as crisp as Swedish bread…

Perversions and Subversions: the Moondrop Spaceship at $20 beats the Moondrop SSR and SSP…less accurate but the better “junk food” for my ears. Moondrop have a history of undercutting their own mid-tier earphones with their budget offerings…we remember the $30 Crescent and the $180 KPE.

Inasmile Cable Protector: Discovery of the year. 20 cents that protect my fraying Apple cables from total breakage.

I still use the Koss PortaPro headphones with Yaxi earpads for video conferencing and listening when I need comfort around my ears. Also great are the Koss KSC75. Grab all of them when you can, they are affordable standard staples. And my standard full-sized cans are still the Sennheiser HD 600.

Tempotec Sonata HD Pro dac/amp dongle ($40): comes at the price of an adapter – but with all possible adapters to connect this little rascal to anything, including iPhones. Good enough to drive any iem. The very best dongles are the $199 EarMen Sparrow run on their balanced output, and the $120 Earstudio HUD100. In terms of larger portable dacs/amps (with integrated battery), I like the $199 ifi Audio Nano BL, the $149 ifi Audio hip-dac, and the $249 EarMen TR-amp. And I don’t think I need a bigger desktop amp.

Question mark of the year: The KBEAR Believe with their Japan sourced Beryllium drivers were too cheap to be true…which was underlined by some competing cheater Be-less Beryllium earphones and doubt seeded by the Dunu competitor. Hey, but the Luna have that Chi-Fi peak…

Personal Disappointment of the year: the continuing Chi-Fi peak between 2 and 4 kHz that kills western eardrums…TRN are leading the charge…the TRN BA8 cuts steel like butter.

Kazi Mahbub Mutakabbir…Munich, Germany

I’ve tried and reviewed more stuff this year than ever, and part of it (actually, most of it) is due to the awful home-arrest that we’ve all succumbed too. Hope things get normal soon, sigh.

IEMs: 

Final E500 ($20): This otherwise “cheap/beater” IEM does one thing better than *anything* under $100 – binaural tracks and gaming. At least it did so until its brethren VR3000 came out, but I’m yet to hear that and that’s got a 4x price tag attached to it. People call the Sony MH755 the best value IEMs, for me it’s the Final E500.

Dunu Studio SA6 ($550): This is a great all-rounder IEM. Great bass for an all-BA IEM, the lower-mids are full and organic whereas upper-mids tread the fine line between forwardness and shoutiness. The treble has good amount of sparkle and air. Great design and accessory pack. Really, hard to pick a fault.

Honorable mentions: Final E5000, Samsung Galaxy Buds, Moondrop Blessing 2, Sony IER-M9, Final FI-BA-SS, Dunu Luna

Headphones:

Koss PortaPro X + Yaxi Pads ($40): Just buy one. Don’t be stingy. Thank me later. 

Sennheiser HD650 ($300): The once and forever king. The HD6XX esp is a no-brainer. Scales better than any headphone I’ve tried.

Honorable Mentions: Hifiman Sundara, Focal Clear, Final D8000

DAPs:

Sony NW-A55 ($200): If your primary need is to run efficient IEMs, look no further. Great ergonomics, actually usable UI, good display, fantastic battery life, and then there’s the MrWalkman mod to turn it even more awesome. The only “budget” DAP I recommend. 

Questyle QP1R ($600): Questyle made the QP1R 6 years ago. It’s still one of the best DAPs out there when it comes to overall dynamics.

Honorable mentions: Cowon Plenue V, iBasso DX160, Sony ZX300

Desktop sources:

YULONG Canary II ($230): One of the best budget all-in-ones I’ve come across. Criminally underrated too which is a royal shame.

Questyle CMA-400i ($800): The all-in-one system I ended up with after countless trials and tribulations. Perfectly aligned to my tastes.

Honorable Mentions: iFi Zen Can, Headamp GSX-Mini

And that’s a wrap. Hopefully 2021 brings us better times.

KopiOkaya…Singapore

This year there are 8 of us, thus there are more choices for our readers to choose from.

This year also marked the year of COVID-19…. Meaning, people are staying home longer and more often, thus they can listen to their gears on desktop systems other than portable music players and phones. Fortunately, desktop gears are much better and more affordable now.

Desktop DACs:

Denafrips Ares II (US$700): I don’t own one but my friend do. If you like natural, organic sound with a huge, deep, tall soundstage and don’t mind its higher price tag, look no further… This is it! 

Topping E30 (US$130): A nice warm-neutral DAC. It doesn’t sound as natural, as organic or has a huge soundstage like the Ares II but it offers great audio at an affordable price.

Note: Extremely sensitive to the quality of power supply used. Make sure you power it with something decent like the iFi iPower X.

Desktop Amps:

Yulong Canary II (US$250): This is actually a DAC/Amp with a Class A amplification stage. It posseses a warm-neutral sound signature with lots of low-end drive thanks to the Class A topography. Very good value and performance consider this is both a DAC and an amp! 

Topping L30 (US$140): My current reference amp… If you have noticed, so far I don’t have any balanced amp in my list. When I tune earphones, I never tune them in balanced, simply because if it sounds good in single-ended, it should sound even better in balanced… Well, this is usually the case! The L30 is great (for me) because it has a gain REDUCTION switch for IEMs with high sensitivity… Not many headphone amps have such feature. This is a very neutral, clean and transparent amp that doesn’t colour the sound of the source. That’s all I ask for when tuning earphones.

Portable DAC-Amps:

FiiO BTR5 / Shanling UP4 / EarStudio ES100 MK2 / Qudelix 5K (US$120 or less): I don’t want to decide which is better. To me, each has its pros and cons but my point is… acceptable Bluetooth quality listening is finally here! Almost everybody owns a smartphone these days, so why not use it as a music player? Some of you despise this idea but c’mon… A TOTL DAP still runs slower than my $150 Android phone operating on Android 10.

Earphones:

Etymotic ER4XR (US$350): My reference for tuning hybrid earphones. If you are familiar with Etys you should know their earphones have a near-neutral Diffuse Field Target tuning. The “XR” version has slightly more bass. 

Etymotic ER2XR (US$100): Similar to the ER4XR except this uses a single dynamic instead of balanced armature, thus my reference when I tune dynamic earphones. The ER2XR has more natural timbre and punchier bass than ER4XR. You can forget about Moondrop SSR/SSP if you plan to buy one. This is better.

Note: Etymotic earphones are to be worn deep inside the ear canals touching the bone… #Etyheads call “deep insertion”. This can cause discomfort to first time Etymotic users but you will get used to it eventually… I used to hate it but I am OK with it now.

Headphones:

Singapore is too damn warm for headphones, unless using air-conditioning while listening to music… Sorry, I am too cheap for that. Electricity is expensive here.

Loomis Johnson…Chicago, USA

TRN STM–$20 wunderkind is not, as Durwood aptly states, a purist’s earphone, and it veers towards sounding over-pixilated and artificial. However, it has that certain toe-tapping rightness that keeps me reaching for it over much pricier “audiophile-tuned” pieces. Did I mention it’s $20?

KBEAR Diamond—you can spend a lot more and get a bigger stage or a richer timbre, but this smooth, highly-resolving single DD is awfully refined for the price, with class-leading coherence and premium aesthetics and build.

Cambridge Melomania TWS—they don’t have ANC, EQ customizability or the bells and whistles of their Apple/Samsung peers, and microphone is sub-standard. However, they sound damn good for wireless buds—and are surprisingly good value at <$99. 9 hour battery life a plus.

Honorable Mentions: Shozy Rouge, Shuoer Tape.

Slater…Cincinnati, USA

Slater is short for “See Ya Later”…and you will see him later…
