]]>

In a sort of Nigel Tufnel/David St. Hubbins fire/ice schism my learned colleagues Alberto and Durwood have offered completely different takes on the 7Hz Timeless, with Alberto finding them lacking microdetail and unrefined in the treble, while Durwood praised their transparency and resolution.

I lean closer to Durwood on this one—with sufficient power, they epitomize the best qualities of planars—speedy transients, tight (if lean-textured) bass, energetic big-sounding midrange and highly resolving high end which captures the little nuances of acoustic guitars as well as anything I’ve heard at this price point.

I do agree with Alberto that some midbass oomph is missing and that they’re prone to a slight shoutiness/steeliness on some higher frequencies—saxes and female vox can occasionally sound overbright.

The 7Hz Timeless are also a poor match for mobile phones or less powerful sources. However, feed ‘em right and they are damn good and well worth the $200.

SMSL SU-6 DAC and SH-6 Headphone Amplifier/Preamp Review (1) – Bargain… https://www.audioreviews.org/smsl-su-6-smsl-sh-6-review-lj/ https://www.audioreviews.org/smsl-su-6-smsl-sh-6-review-lj/#respond Tue, 26 Apr 2022 22:24:35 +0000 https://www.audioreviews.org/?p=55503 Much more than a beginner's setup...

The post SMSL SU-6 DAC and SH-6 Headphone Amplifier/Preamp Review (1) – Bargain… appeared first on Audio Reviews.

]]>
SMSL SU-6 and SMSL SH-6: One can’t help but be impressed by the build quality and the feature set packed into this sub-$300 duo—bluetooth, preamp functionality, remote volume control and input switching, adjustable digital filters, gain settings, etc.

Granted, there’s some evidence of cost cutting—no balanced outs, and the front panel switches and volume knob on the headphone amp seem a bit flimsy, but work as intended. Little of this would, of course, matter unless the SU-6/SH-6 sounded good, but fortunately they do.

As a headphone amp, the SH-6 isn’t a powerhouse (it hits its limits with my  250 ohm Beyers), but immediately impresses with its low end impact and control—slightly boomy IEMs like the Moondrop Kanas Pro  sound tighter, while more balanced pieces like the Whizzer Kylin HE03D or the 7Hz Timeless show palpably more low end depth and presence.

Other than juicing up the bass, the SH-6 is quite neutral in tone—neither bright nor warm–and added very little coloration across the spectrum. Compared to my trusty (tube) Aune T1 MK2, the SH-6 played louder, had the more expansive soundstage and presented a lot more high end detail; the Aune had the more analog, organic timbre, with the SH-6 sounding a bit leaner and more processed, albeit more resolving.

My ($150)  Project Head Box S2 actually was a close match tonally for the SH-6, with a comparable level of high-end detail, but lacked the bass thwack and speed  of the SH-6.

Moving to the headphone section of the pricier Chord Mojo gets you a richer, fuller-bodied sound, with noticeably better loud/soft dynamics and a wider stage. However I actually thought the bass on the SH-6 was crisper and extended deeper than the Mojo’s, which sounded smoother and not as sculpted.

The SH-6 likewise functions very serviceably as a digital preamp, again maintaining its neutral tone and tight bottom end, although careful pairing with sources/speakers is necessary, as the SH-6, in high-gain mode, can get a tad shrill with higher output devices or very sensitive speakers. 

The SU-6 DAC was initially the more intriguing of the pair, largely because of its lineage from the genuinely great ($450) SU-9, with which it shares a variant of the ES9038 chip. While I usually avoid measurements and graphs (which often skew my impressions on how a piece actually sounds), I cheated on this one and checked out Audioscience Review, which showed extremely good measured performance, including very high SINAD. In fact, the SU-6 was dead quiet, with no audible distortion.

As a standalone DAC (decoupled from the SH-6), the SU-6 sounded slightly bright, with a taut note texture and mostly balanced throughout the spectrum, with an etched, slightly sharp-sounding high end which can sound a little intense on amplified instruments (note that the adjustable digital filters have a small but audible effect on mitigating the intensity).

Microdetails are very present (you can clearly hear the difference between 32/768 files and lower rez stuff), though Bluetooth streaming sounded like typical Bluetooth—compressed and somewhat rolled off at the high end.

Paired with the SH-6, the SU-6 takes on the bassy-but-not-bloated character of the amp, while retaining its slight harshness at the highest frequencies. It’s a good combo nonetheless, with a high level of resolution and good PRAT. The 3x pricier SH-9/SU-9 combo, at least from memory, is more powerful and refined at the high-end, though the qualitative differences are incremental. 

Most of the other reviews I’ve read have labelled the SH-6/SU-6 a good “beginner setup”, and like anything else you can certainly spend more and get better. Frankly, unless you’re driving 600 oHm planars I wouldn’t feel a lot of compulsion to upgrade from this little stack—it does many things well and its bass quality trumps a lot of pricier pieces. Bargain.

RHA CL2 Review – Hands Down The Best Planar Yet https://www.audioreviews.org/rha-cl2-review/ https://www.audioreviews.org/rha-cl2-review/#respond Fri, 22 Apr 2022 20:11:30 +0000 https://www.audioreviews.org/?p=54544 They deliver an incredibly refined clear and lifelike presentation...

The post RHA CL2 Review – Hands Down The Best Planar Yet appeared first on Audio Reviews.

]]>
I never fell in love with the planar timbre, neither in the end I did this time. It’s just not precisely my cup of tea. Yet this time it was a much closer call, really. What I heard is no doubt a full class above any other chifi planar I auditioned to date.

This piece is to report my experience with a glorious piece of old world technology, Scottish RHA’s CL2 planar IEMs. A privately owned sample was sent to me by an audiophile friend for assessment, and I now understand his love and jealousy for the item indeed.

Currently discontinued, these IEMs were marketed for around €900 back in their day (some 2-3 years ago).

Test setup

Apogee Groove+Burson FUN / E1DA 9038SG3-3000 – final E clear eartips – lossless 16-24/44.1-192 FLAC tracks.

Signature analysis

Tonality

RHA CL2’s tuning as it comes out of the box is – simply put – just flawed. Based on a somewhat wide-v general shape, highmid frequencies (2-4Khz) are ununderstandably over excited which inevitably stirs the presentation into a bad sort of shout party. Sub-bass could also do with some more body physicality, but that’s minor in comparison. Highmids, as is, are just undefendable.

That’s bad, but that’s at least as bad as it gets. The great news instead is that RHA’s driver’s elasticity vs even important equalization corrections is close to divine. Using an ordinary PEQ you can push and pull frequencies as you please and CL2 will follow you pretty much into the tonality you exactly want.

The general timbre is that of a (high end) planar driver, so clear, defined and neat, therefore don’t expect what you can’t possibly get, e.g. DD-style attack in the bass, but within that you are free to think to CL2 as a blackboard to draw the tonality curve you prefer on, and that will be nibly delivered.

For my taste fast drivers (like planars) strictly relate to acoustic music like bebop or classical, and that’s why I shaped a sort of mild Vshape, with elevated high mids within the classical DF boundaries on one end, leaving the existing midbass where they are. More on this here below.

Sub-Bass

Sub bass is extended but less prominent than midbass. Especially for acoustic jazz application, a nudge up is really beneficial to standup bass and similar key instruments. A low shelf of +2 / +3dB is recommended.

Mid Bass

CL2 midbass is just great within its planar category. It has pretty much everything you can dream of: speed, definition, texture, detail retrieval – with the sole important limitation of gutt-felt attack which is of course technologically offlimits. Forget any distortion, barred of course that coming from your source so – beware! – CL2 are totally unforgiving on that. Use a clean source, or be ready to hear how dirty your source is. Musically speaking don’t feed them with Pink Floyd, just don’t. Feed them with Andrew Cyrille.

Mids

As previously mentioned, the first thing to do here is removing that elephant from the room: high mids need to be tamed down. I’m putting -3dB around 2.5/3Khz and another -4dB around 4Khz. Then we can talk: mids are now clear, defined, engaging, very detailed and somewhat lean.

Vocals

Vocals are a bit lighter than organic, both male and female although in slightly different ways. An (optional) way to add a bit more body to lower mids vocals in particular is by adding a +3dB high shelf hinged at around 7/800Hz. In such case of course the previous negative bell values at 3 and 4Khz need to be negatively increased by the same quantity. Don’t take notes here, I’ll add an EQ suggestions recap at the end 

Highs

CL2’s trebles are very good, sparkly, detailed, while making sure to stay on unoffensive territory. Even too much. Too much christiandemocrat, if the term makes sense to you. Beyond sonic preference, this is another example where CL’s agility vs equalization offers you an experimentation liberty that’s simply missing elsewhere: go head, adventure into pumping air trebles and last octave up … until you like or can bear. Just push: CL2 will follow, no distortion.

Equalization Recs recap

OptionalHigh Shelf 6200hz [+6dB] Q:0.9
or [+3dB] in case the lowmids correction is in place
Play with the +dB value to find your ideal airness

Technicalities

Soundstage

CL2 offer very good space sizing both accross and in depth. Not the “most huge” room I heard yet in line with expectation on this price level, and vis-a-vis the other high quality technicalities on the product.

Imaging

Macrodynamics are very good, instrument placement is correctly executed in all occasions and casting on the stage comes accross as credible an fully natural

Details

Detail retrieval on highmids and trebles is finely granular and inoffensive / unfatiguing at the same time – an extremely difficult and therefore rare balance to achieve per my experience. Very good detail extraction also happens from mids and bass, with the sole already mentioned caveat regarding planar timbre necessarily keeping bass just a shiff south of truly organic, which also impacts on the realism of their details of course.

Instrument separation

Separation and layering are beyond beautiful; precision and definition are really outstanding and fully worth the price tag and much beyond.

Driveability

CL2 are extremely demanding in terms of amplification. They require a “high minimum” in terms of current delivery, and furtherly positively scale with the amp’s qualities. Amongst the multiple and diverse sources I have available in the end only desktop gear gave CL2 some serious glory, with the sole notable exception of E1DA’s 9038SG3 and 9039D. Pretty much everything else I have at hand right now doesn’t “open” them up appropriately due to scarse current delivery.

CL2 also easily pick hiss up from the source (in my case: Burson Fun), while on the other hand they prove quite resilient to FR skewage even when the amp pair offers a sub-idel damping factor (again for my case: Burson Fun).

Physicals

Build

Ceramic shells following the classical RHA shape are at the same time solid, resistant and – for my taste – greatly stylish to look at

Fit

CL2 fit rather well into my outer ears, although they tend to stay not perfectly still especially vs mandibular movements.

Comfort

Comfort is ok once fitted. The shape is not 100% ideal to me, but its rounded surface helps minimising pain points and such. Above average anyway.

Isolation

Passive isolation is rather average.

Cable

The privately owned unit I borrowed came with a third party cable so can’t comment on stock one(s).

Comparisons

7Hz Timeless

An unfair comparison looking at price tags: €200 for this chifi thingie, €900 for the scottish one – the latter better be really good ! Dual unfair insofar as per my previous piece on Timeless I don’t find those particularly brilliant even in their own price class. I’m mentioning them mainly due to their recent hype.

Similarly to CL2, ootb Timeless presentation also comes accross as flawed: a major distortion point at 9300Hz introduces a nigh-ridiculous, very invasive artificial tint to the timbre, which must be eliminated or the product is just unaudible, to me at least. Timeless also can benefit of some further sub-bass elevation, again like CL2 does. End of the similarities.

Timeless’ driver is very obviously less refined than CL2’s (heck! at 1/4th the price…) and this results in a much more pronounced, and unpleasant, “inevitably planar” timbre in the first place, and a dramatic lack of texture and detail in the bass line which is dull, uninspiring.

Timeless’ highmids are less shouty than CL2’s out of the box, but they still need EQ correction. No problem, if not for the fact that when downtamed Timeless’s high mids become dull, while CL2’s stay fully vivid, and extremely pleasant.

Even more importantly than all that precedes, Timeless’ technicalities are a joke compared to CL2’s: instrument separation is underwhelming at the very least on Timeless (even vs some non-planars by the way), microdynamics and detail retrieval are nothing more than average un the highs, inexistant from the bass, and soundstage depth is MIA (as in: Missing in Action), whereas CL2 ticks all those boxes with great competence, with a sole sub-top remark reserved to microdynamics which could be even better weren’t for the superfast driver nature of course.

Campfire Andromeda [2020]

Based on a totally different driver setup (5 x BA vs 1 x Planar) comparing Andromeda with CL2 is significant on 2 counts: their sonic presentation (speed, detail, timbre) and their prices categories (€900 vs €1100) are close enough.

You may read my take in detail on my earlier piece about Andromeda [2020], here let me go straight to the point: beyond their differences, Andromeda and CL2 share an almost magically spot-on balance between detail retrieval and control, resulting in smoothness all accross the board.

Neither are my exact cup if tea in terms of timbre: both is too fast, too technical for me. Of the two, CL2’s planar timbre is less pronounced than the (in itself decently moderately at the very least) Andromeda’s BA. What’s totally stunning on Andromeda, and even more so when directly compared to a single-driver product like CL2, is their tonal and timbral coherence across the entire spectrum, and the 5 different drivers working under the hood.

Conversely, and correspondingly, CL2’s single driver needs not pay any toll to the 5 (say: five) different drivers employed inside Andromeda in terms of bilateral extension, articulation, detail retrieval.

Both on my scoreboard excel on the same macro points: the already mentioned resolution/smoothness balance and timbre cleanness and clarity line up in both cases with superb treble delivery, and beyond good imaging, separation and layering. Again, both show their limits on bass texturing and microdynamics in general – which is of course inherent to the very nature of the driver technology of choice in either case.

Andromeda are much less elastic to heavy eq compare to CL2, on the other hand they require much less as their presentation is way more than viable already out of the box. They require much less “power” to be driven, but not a much “cheaper” source anyway: dealing with their very high sensitivity and very low impedance without turning into hiss or distortion in general is not easy.

Considerations & conclusions

RHA CL2 are just spectacular IEMs and they would still be worth every single cent of their price tag if they hadn’t been discontinued as a part of RHA’s disengagement from the higher segments of the audio market. The sole possibility is now finding a good preloved unit.

They deliver an incredibly refined clear and lifelike presentation – a mixture that’s as desireable as rare to effectively find. They can (and must) be freely equalised to have their tonality shaped precisely as per the user taste, and deliver a nothing short of stunning level of technicalities.

Sincere thanks to Simone Fil for the loan and assessment opportunity.

The post Xumee USB-C DAC Dongle Review – A View From The Cheap Seats appeared first on Audio Reviews.

]]>
To allay my grief over the loss of my beloved, headphone jack-equipped LG V50 (which no longer works on T-Mobile’s 5G network) I went out and bought some new dongles, of which the diminutive, $13 Xumee was the first to arrive.

Even allowing for some recency bias, the Xumee immediately registers as a real find, with a full-bodied, crisp attack, good driving power and notable dynamics and bass impact. It synergized surprisingly well with my new crush, the difficult-to-drive 7Hz Timeless, which sounded louder and more  expansive with the Xumee than they did unamped.

Likewise, the 60 oHm Koss KSC75 took on a palpable physicality with the Xumee, sounding bassier and more like full-sized cans. The Xumee did run out of steam on my 250 ohm Beyer DT 990, which had sufficient volume but sounded wimpy and bloomy at the low end.

On more sensitive (<32 ohm) IEMs, the ($13) Conexant CX31993 sounded more transparent and presented more high end detail, but lacked the energy and low end control of the Xumee, while my current budget fave,  the $23 Meizu Master, matched the Xumee for output power and impact, but sounded a bit coarse in comparison, with a bit of graininess at the high end.  

Moving up the food chain to the $70 Hidisz S3, however, demonstrated the Xumee’s budget roots—while the Xumee played louder and had more low-end presence, the S3 was clearly the more refined, with more lifelike, less artificially bright timbre and a smoother (though still quite detailed) high end. However, the Xumee was a better match for brighter IEMs like the Blon A8 and Whizzer Kylin HD03D than the $75 Audirect Atom 2. So much for price/performace.

While my personal donglequest will undoubtedly continue, I’d venture that among the current flood of barely-distinguishable cheap dacs the Xumee is likely the best.  I’m glad I bought it instead of that fifth of Jim Beam.

On a somewhat related note, I also sampled the surprisingly cheap ($9) Apple USB-C audio adapter, which Jürgen has reviewed favorably here. Simply stated, the Apple does not play well with any Android or Fire devices, producing very low volume and a rolled-off high end.  

The lightning version, OTOH, works perfectly well with my wife’s iPhone, with more than adequate output and a very clean, uncolored presentation. I’m not sure what Apple’s reasoning is here, but if it don’t work it ain’t a bargain.

Non-disclaimer: bought it myself . You find it at amazon.

KBEAR Aurora (Review 2) – Elegant Color Remix https://www.audioreviews.org/kbear-aurora-review-2/ https://www.audioreviews.org/kbear-aurora-review-2/#respond Sat, 12 Mar 2022 18:49:25 +0000 https://www.audioreviews.org/?p=53413 The color refresh of the KBEAR Aurora is much more elegant than the original shiny launch color scheme...

The post KBEAR Aurora (Review 2) – Elegant Color Remix appeared first on Audio Reviews.

INTRO

Lately there seems to be an overwhelming desire for budget brands to break into the mid-tier market. There was not a lot of room to wow and differentiate in the budget class and now it seems we are seeing the same happen in what I consider the mid-tier $100-200.

While there is a whole wide range of offerings way upwards of that price range, they are more dangerous to your wallet as it starts reaching bragging rights and earning style points. Those I consider niche products.

The KBEAR Aurora was released an eternity ago in terms of fast fashion IEM’s and the only reason this comes to me now is a color refresh. One of our past reviewers Baskingshark had his go at them. We have some pretty strong $200ish contenders with recent hits such as the 7Hz Timeless now being challenged by the less expensive LETSHUOER S12, and the brilliant Moondrop Kato at $190.

Before that, people were singing the praises of the Drop JVC HA-FDX1 which runs between $200-250. The great thing is that all 3 of those have completely different strengths and tunings. So with value out the window, the KBear Aurora has to stand on it’s own and hope it doesn’t get lost in the sea of choices. I realize these have been out for 6 months and have already been forgotten. Just another NFAudio NM2+ perhaps, but in a better way.

Disclaimer: These were sent gratis via Keephifi and I hadn’t realized they were already released 5-6 months ago. Warm fuzzies were not exchanged until right now while I thank them for sending a pair to check out. I did not pimp my soul to promote these.

GOOD TRAITS

  • Good universal fit and solid construction
  • Good accessories
  • Full sounding bass
  • Perfectly sized carrying case
  • No sibilance which should be standard for anything trying to sell for over $70. A low bar to clear in my opinion.

NEEDS IMPROVEMENT

  • Low value
  • Treble lacking in resolution and extension

PACKAGE CONTENTS

As with most Earphones over the $100 mark, the KBEAR Aurora comes packed into an easy open larger package that failed to keep the ears in place during shipment. I don’t typically care, but these are metal earphones so bouncing around in packaging is not a good thing given they can easily leave marks on the housings given the sharp edges on the faceplate.

The matte antique bronze color is definitely classier looking than the gaudy 1980’s neon chrome fingerprint magnet trend of the blue/chrome color. I think they should have released it solely in the matte brown first.

The braided gray snake skin looking cable is highly flexible and microphonic free. I notice the 2 pin connectors fit semi loose into the plugs however. The chrome/blue version sported a blue colored cable of the same style.

Two different sets of eartips, S/M/L of a standard widebore with a normal thickness stem, and 5 sizes of the main set that includes a widebore thick stem the same length of the outer tip.

SOUND

Right away it is easy to pick up the eastern style midrange boost that presents as a very in your face forward vocal. Snares are snappy as they should be. This hot upper midrange is preceded by the medium blend boosted bass that barely tickles the seismic region while going full bore into midbass territory with snappy and articulated fullness. Feels perfectly damped and well balanced with rest of the frequency range if you prefer stew over soup.

The treble on the KBEAR Aurora is the least noticeable asset. Inoffensive, bland and just one of those jobs you have to do but don’t put much effort to complete. The problem with this style of tuning is the upper midrange is so over-powering the treble doesn’t really get a chance to showcase what it can do.

For me the treble gives me the sensation of having stayed too long at the discotheque and consumed too many adult beverages. It is not particularly well defined. This was the same problem I had with the recently reviewed Whizzer Kylin HE03D. I have been ruined by the precision and air of the 7Hz Timeless and the control of the luscious Moondrop Kato.

TECHNICALITIES

The KBEAR Aurora sounds expansive, but lacks in depth. Clarity is only average with some cloudiness in the treble mucking things up. No real issues with the timbre until you get past the lower treble, it’s a single driver tuned in a typical +10db pinna gain in the upper midrange. It is driven easily by a smart phone, and has medium isolation.

COMPARISONS

Earlier there were hints at maybe a NFAudio NM2+ ($159) clone because to my poor memory I thought they were tuned similarly. Upon a review, the NFAudio NM2+ is a really hot intense listen, the Kbear gives my ears a break in comparison. Bass is very similar with the KBEAR Aurora recognizing lower extension is important.

The treble is still a bit chewed up sounding on the Aurora, but the NFAudio has so much upper treble my ears just give up looking for the upper end extension. Point goes to Kbear. Width and spacing sound more balanced on the Kbear Aurora. Fitment and isolation are similar.

The BQEYZ Spring 2 ($169) is another good comparison given the price bracket. The BQEYZ suffers from the droning bass tendencies again showing the KBEAR bass is tuned to be midbass centric as well with subbass only having a minor supporting role. Switching back and forth the BQEYZ Spring 2 can actually sound tiring due to this. Vocals sound smoother and treble is cleaner on the BQEYZ Spring 2, but the KBEAR Aurora seems to present more width in the staging aspect although lacking some treble resolution and extension.

When this was previously released the Moondrop Kato ($189) was just on the horizon, but now it’s available for only $20 more than the KBEAR Aurora. The Moondrop kato is more delicate sounding with a much lighter presentation than the Aurora.

The lower midrange/midbass boost give the KBEAR Aurora a more intimate smaller room presentation, but the treble lacks the resolution and clarity of the Kato. The Moondrop Kato has better resolution, more depth and a lighter airy feeling in comparison as if listening in a concert hall. Width feels comparable.

Also check Baskingshark’s review of the KBEAR Aurora.
And that’s what Loomis has to say about the KBEAR Aurora.

FINAL REMARKS

The color refresh of the KBEAR Aurora is much more elegant than the original shiny launch color scheme, however other brands have encroached on the pricing territory. It is a capable sounding IEM, I just have trouble recommending it based on value and a cloudy treble region. On the plus it is not a screamer or ear-piercer with most of the focus on the low to middle region, with good build and an above average accessory package.

The post LETSHUOER S12 Review – Compared to 7Hz Timeless appeared first on Audio Reviews.

]]>
Pros — Articulate bass and very good treble extension, great note definition and cohesion, superb resolution (!!!); very good build and fit; great cable; value.

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.

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.

Specifications of the 7Hz Timeless
  • Plug Options when ordering 3.5mm or 4.4mm
  • Impedance: 14.8 ohm.
  • Sensitivity: 104dB.
  • THD+N: <0.2%.
  • Frequency Response: 5Hz-40kHz.
  • Product Weight: 5.5g/single earbud
  • MMCX

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).

LETSHUOER S12
The LETSHUOER S12’s rather wiggly frequency response is typical for planar magnetic drivers.

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.

LETSHUOER S12 and 7Hz Timeless

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!

INTRO

Lately there seems to be more and more flat driver tech infiltrating the in ear headphone market. Flat drivers differ in how they produce sound in comparison to dynamic drivers. Flat diaphragm driver like planars rely on the bending characteristics of the material itself to produce sound waves, whereas in direct opposite the dynamic driver tries to maintain it’s shape through various geometries and materials to stiffen it up so that it can act as a piston and minimize bending waves. These two concepts are transverse (planar bending) and longitudinal waves (dynamic piston).

This year I had considered the PMV PP flat planar but then 7hz exploded onto the scene with the 7Hz Timeless 14.2mm flat planar IEM with much fanfare. I succumbed to the temptation and bought a pair to see if this hype was warranted. By now this is probably the 101th review of these, so I took my time to get on board. 7Hz Timeless dazzles with it’s resolving sub-bass infused Harman tuning or U signature, with analytic grace.

Disclaimer: I had some Amazon gift cards burning a hole in my pocket so I purchased during the 11.11 weekend sale from Hifigo on Amazon. We buy our own stuff sometimes believe it or not.

GOOD TRAITS

  • Generous eartip selection
  • Clarity, Resolution
  • Above average isolation
  • Lightweight

NEEDS IMPROVEMENT

  • Bass is tuned very low, the transient speed does not match
  • Not the prettiest of the bunch
  • Channel matching throughout the treble
  • Needs more than a smart phone to shine.
  • Missing holographic elements

PHYSICAL / PACKAGE

The shape is interesting, the flat round faceplate hides a rather simple shell. The flatness and grooves provide a simple and painless way to insert them into your ears. With rounded shells, I find myself fiddling and losing my grip sometimes.

An unassuming silver twist detachable cable with a simple earhook comes with the 7Hz Timeless. It coils well, and does a good job of avoiding microphonics. They took my favorite qualities except for one, the mmcx connection. Cable snobs will find it boring looking.

The carrying box seems overly large and heavy, looks awesome sitting on my desk and could be used as a defense mechanism in a pinch by chucking at ones head. Surprisingly it doesn’t appear much larger than the Moondrop Kato case and will definitely allow you to know if you forgot to put it into your pocket.

PACKAGE CONTENTS

  • Detachable MMCX Silver cable
  • Metal carrying case
  • 3 sets of S/M/L eartips -Medium Bore, Small Bore, Bowl shaped medium bore with carrying cases
7Hz Timeless
Moondrop Kato vs 7Hz Timeless

SOUND

Tested with LG G8, Sony NW-A55 and Liquid Spark DAC+JDS Labs Atom

First the very noticeable sub-bass is front and center and the fact it goes so low and is boosted causes some speed issue for me given the rest of the quick and precise nature of the 7hz Timeless. The lift in the bottom end really lets upright bass and bass drums fill your head with extreme lows, but not in the basshead ear tickling ways. Since the slight boost is pushed so low, there is no bass bleed into the lower midrange.

Velvety smooth vocals complement the rise into the upper midrange, there is excellent darkness that allows the midrange to feel the space or environment of the recording. Horns and present flare and sharpness that provides realism, these are not for relaxed listening but instead for enjoying the nuances of the music and deep listening sessions.

Acoustic guitar plucks are rendered with such resolution as to not get lost in the macro details. Snares, cymbals crash through with sharp well defined precision. Sibilance is non-existent unless purposely in the recording, and there is plenty of airiness to make these a lively set.

TECHNICALITIES

Resolution and transparency is outstanding for the 7Hz Timeless. Width and depth are equally balanced and height information comes through as well. It is really hard to find any faults other than they need some power to extract their full potential. On the sensitivity topic, the LG G8 did just ok but I found myself at the higher volume range.

The Sony NW-A55 was a better fit so this is probably one of the bigger shortcomings given IEM’s are normally geared for mobile use. Given their extreme analytic qualities, I find longer listening sessions can be fatiguing because the 7Hz Timeless really demands your attention.

Also check Loomis’ take on the 7Hz Timeless.

COMPARISONS

Shozy Form 1.4 ($180) vs 7Hz Timeless ($180-$220)

Warmer bass, damped treble, thicker vocals is what stands out when swapping to the Shozy Form 1.4, my go to IEM these days. It offers a more relaxed presentation for nights when I want to wind down. The 7Hz Timeless instead offers a thinner lower midrange with deeper bass registers and more sparkle and more cymbal shimmer. The Timeless invites a more critical listening experience due to the flat soundstage. The Shozy Form 1.4 shell feels more premium, and might add a subliminal cue despite being near the same price bracket.

BQEYZ Spring 2 ($140-170)

Presence region is enhanced on the 7Hz Timeless, just more shimmer and air compared the BQEYZ Spring 2. The Spring 2 sounds warmer with fuller vocals due to the higher frequency bass hump veering towards midbass, it lacks the control of the Timeless as well. The treble enhancement on the 7Hz Timeless gives the appearance of more resolution and clarity but both are solid performers. Transient speed is quicker on the Timeless.

Moondrop Kato ($190)

7Hz Timeless has a flatter soundstage and a U shaped signature vs VSDF signature on the Kato. Bass on the Kato has a 2 channel stereo large tower vibe while the Timeless is rocking a 2 channel system with an audible subwoofer. The Moondrop Kato is more forward and brighter, while the Timeless has an enhanced cymbal linger. Weight is also a factor, both the cable and shell of the Moondrop Kato offer a more premium feel due to the heft factor, but it is also more noticeable compared to the lighter and nimble 7Hz Timeless. The cable on the Kato is approaching lamp cord thickness boundaries. The eartips on Moondrop Kato are superior and have that Alza Xelastec stickiness feel, while the Timeless offers a generous pick of off the shelf tips. Read up on Jurgen Kraus’s detailed review of the Moondrop Kato for more info.

7Hz Timeless

WRAP UP

Given the many glowing reviews for the 7Hz Timeless I have to agree the praise is real for available planer IEM options despite it’s flat sounding 2D staging. Another purchase I whole heartily feel was “worth it” and “nice to have”. For those that enjoy squeezing out extra resolution from the first and last octaves or U shaped signature, put these on your short list.

Finally a planar IEM that we have been waiting and hoping for. In comparison to value, there are better options if non-planar IEM’s are factored in, such as the Moondrop Kato that provides better technical abilities and an overall whole premium package. By the time this is published another planar follows very closely in the footsteps of the 7Hz Timeless, so they did something right.

Coblogger Kazi forwarded this pair of 7Hz Timeless to me for assessment and I spent some time listening and playing with them. As many already know 7Hz Timeless are based on a single quite sizeable (14.2mm) planar driver, which of course already sets the expectations in a sense. They come with a not totally insignificant retail price tag ($219,99), and can be purchased here for a bit less than that.

At-a-glance Card

PROsCONs
Engaging U-shaped presentation. Artificial nuances in the timbre.
Good sub-bass. Untextured, undetailed midbass.
Nicely wide soundstage.Unrefined, moderately shouty and fatiguing trebles.
Lightweight and comfortable.Dramatic lack of stage depth.
Nice stock cable.Scarce midrodynamics and detail retrieval.
Unsatisfactory instrument separation.
Tip sentitive.

Signature analysis

TonalityGeneral presentation is a quite evident U-shape with important bass and trebles but still unrecessed mids and vocals. Midbass although authoritative doesnt succeed in adequately balancing the tonality which can be defined as moderately bright. The timbre is quite evidently planar-lean, with some unwelcome artificial tint especially on the high-mid and high registers.
Sub-Bass7Hz Timeless offer a quite elevate, fast sub bass with good rumble and nice precision.
Mid BassMidbass is as quite elevated in quantity, as much disappointing it is in quality. While overall speedy as one normally expects from a planar driver, midbass notes feature somewhat “frayed” transients resulting in quite messy resolution, and severe lack of texture.
MidsMids are unrecessed and quite enjoyable, although more on the high end then on the lower end where they do lack some body and warmth
Male Vocals7Hz Timeless render male vocals reasonably well. Occasionally, some more body would be welcome, and some more warmth too.
Female VocalsBetter than male, female vocals are clear, detailed and quite bodied. Only very rarely they inherit some of the trebles’s timbre artificiality.
Highs7Hz Timeless treble is quite airy, vivid and reasonably detailed. On the down side, treble is mostly responsible for the quite evident “artificial” timbre tint often emerging. Furthermore a definite tendence to shoutyness is there, and carefully selecting the source pair doesn’t seem to cure that, resulting in generally unrefined notes delivery, and a certain degreee of fatigueness.

Technicalities

Soundstage7Hz Timeless draws a reasonably wide and quite high stage, with almost absolute lack of depth.
Imaging7Hz Timeless imaging (macro-dynamics) is above average, or I should say even “good”. Too bad that due to the lack of depth instruments are all basically cast on the same line.
DetailsMicrodetails are virtually inexistent on the low end, and below average on the highmids and trebles where they get lost in the general lack of refinement
Instrument separationWithin the limits of very limited microdynamics and detail retrieval, instrument separation is good on 7Hz Timeless on non-crowded passaged, whereas it goes down the drain on crowded situations where bass’s lack of texture, treble’s lack of refinement and 2D imaging all negatively contribute to deliver an unclean result.
DriveabilityWhile not demanding in terms of current as much as many other planar drivers on the market, 7Hz Timeless do require a bit of pairing attention to try and limitate some of its shortcomings. A source with outstanding bass control is first of all strongly recommended. A warm source is also welcome due to Timeless’ relative dryness in that sense.

Physicals

BuildI did not witness any of the QC issues that I’ve read reported by other users. The housings appear solid and well assembled. MMCX connectors are of apparent good quality and stock cable connectors plug in with a convincing click.
FitTip selection is very critical. Either foams, or soft silicon tips strongly recommended to help with midbass definition.
ComfortOn my ears 7Hz Timeless are quite easy to fit and stay firm, once the right tip size is selected.
IsolationIn spite of their shape and quite important outer size 7Hz Timeless don’t offer particularly outstanding passive isolation, which I would call just above average actually
Cable7Hz Timeless’ 2-core stock cable is well built, soft and apparently solid. Kudos to the company for offering users the chance to easily order the IEMs equipped with a 3.5, 2.5 or 4.4-terminated cable at purchase time.

Selected comparisons

Vs Tin P1 ($169,00)

P1’s uber-neutral tonality sounds obviously sterile compared to Timeless, which at first impact come accross more engaging and vivid, especially due to the ostensibly more elevated bass line. That said, P1 are significantly better in terms of resolving power, midbass texturing (quite terrible on Timeless), instrument separation and organic timbre.

Both are quite underwhelming in regards to stage drawing, with Timeless a bit better in terms of width, and P1 easily better in terms of depth (easy win there). Both are tip-capricious, P1 more of the two. P1 require higher amping power.

Vs Ikko OH10 ($199,00)

This comparison seems particularly meaningful to me due to very close pricing, and very similar presentation tuning on the two products, based on totally different technologies: single planar for Timeless vs hybrid DD+BA for OH10.

OH10’s sub bass is more extended, more elevated, while still very clean. OH10’s midbass is waaaay better in terms of resolution and texturing, so much so as to not sound offensive let alone invasive in spite of its even higher elevation. OH10’s mids are more recessed – V shape for OH10, U shape for Timeless – yet male vocals in particular sound roughly on par vis-a-vis Timeless’ (relatively) leaner note body there.

OH10’s high-mids and presence trebles are fuller, sparklier, more organic and most of all way more refined than those coming out of the Timeless. Unlike Timeless’, OH10’s timbre never scants into artificial. In spite of their hybrid driver structure OH10 do not loose points in terms of horizontal coherence vs Timeless – if something it’s actually the other way around, due to Timeless midbass’ lack of refinement facing their often shouty, somewhat artificial timbred trebles.

OH10 are no soundstage size monsters, yet they still draw a bit bigger space than Timeless, definitely deeper, while they excel hands down in terms of imaging and most of all instrument separation. Neither IEM require huge amping power.

Also check out Durwood’s take of the 7Hz Timeless.

Considerations & conclusions

I remember when I was a young IT enthusiast playing with my Apple II, back in the 80ies. I was so in love with technology that I just “assumed” that pretty much everything was going to be automatically “better” for the very sole reason of being processed in such innovative ways.

Sadly – or not even sadly, actually – of course my assumption was wrong. There were very selected tasks for which my Apple II was unbelievably brilliant, while quite a few if not most of the other things I insisted on doing with it would arguably have been much better, easier, and faster done “the traditional way”. Woe to those who dared pointing this out to me though! I would promptly call them ignorant, obscurantists, or both. The more so if they had my mother’s face, of course 😉

Technology is still enthrilling 40-something years later, more and more so indeed, and legions of people (not necessarily youngsters …) fall into the same pithole everyday that I was in back then. There’s a new piece of technology. There’s a couple of really brilliant products / application based on that. Ergo: all products based on such technology will be superior. No, it’s indeed a non sequitur.

I’ve yet to hear a really outstanding planar magnetic IEM below $500 which is worth its money. To clarify, by “worth its money” I mean “producing sensibly better results than similar priced products based on alternative technologies”.

7Hz Timeless IEMs are no exception.

Sure they deliver a vivid and engaging presentation, departing from other too algid same-tech competitors.

Yet, simply put they are technically lacking when compared with similarly priced non-planar alternatives: mid bass lacks texture, timbre has a slight but annoying artificial tint, and trebles are too often shouty and fatiguing. Good intent, lacking realization. Maybe we should long for a future iteration ?

In the meanwhile, it all comes down to the purpose of the game as always. Die-hard technology enthusiasts should give Timeless a spin, no doubt: depending on their tastes, their musical preferences, and their gear they will probably find it better, or even much better than other “inexpensive” planar alternatives. Music lovers looking for they highest quality IEMs in the $200-ish region, instead, should keep referring to our Wall of Excellence.

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.

This is work in progress. Please keep checking back…

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!

Not created by a single analyst but by 8 of them…

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!

KopiOkaya…SINGAPORE

Loomis Johnson…Chicago, USA

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.
