Hidizs’ new MM2 earphone features 2 drivers, a dynamic and a magneto-static one. It features three different screw-in outer vents to vary bass response. (you find the physical principles here). I have not had much testing time yet so I cannot yet comment on the sound.

Here you have the opportunity to check out the MM2’s physical features.

The BQEYZ Autumn remidies all previous issues and is the best and most mature sounding iem of the series. In fact it is a very good and enjoyable single DD iem. And it is flexible, sonically, as you can adjust the bass response with the three included front vents.

Before you read my Autumn review, you have the opportunity to check out the Autumn’s physical features. Is the nozzle length right for you, will the shell fit your ears well? Sound quality is only one aspect of an iem’s functionality. And the best iem is the one we use most. Don’t you agree?

This is a visual intro to the IKKO OH2 Opal. IKKO have been a company offering a small but fine selection of iems. That has changed lately as they have expanded into electronics. We at audioreviews.org have followed their iems since their OH1. The $199 IKKO OH10 made it even onto our Wall of Excellence.

The OH10 have a very safe, likeable V-shaped tuning with no peaks or pierces and huge stage. They are a first taste of the premium segment at a mid-tier price…and therefore a rare example of justifying the otherwise hollow marketing term “entry level” (with respect to premium).

The smaller $159 IKKO OH1S shows a completely different tuning with a strictly linear bottom shelf and a rather “vivid” treble that caused some confusion with the reviewers. The rumour arose that the OH1S don’t have “enough” bass and to much spice in the upper registers. In fact, their bass response is just fine and the treble extension may be a matter of taste.

What was also unusual is their oval nozzles for which I had issues finding third-party tips suiting my ears. On the other hand, the included IKKO foams work well in that they provide a good seal and help with the bass.

IKKO responded to the criticism of the OH1S with the new IKKO OH2. They are a tad larger than the OH1S and have the same accessories – at a much lower price. The biggest difference is in the tuning: while the bass shelf was kept the same, upper OH2’s midrange was somewhat reduced, and much of that treble extension was shaved off. The result is a more generally appealing sound.

The SeeAudio Yume is a 1DD + 2BA earphone in the mid tier. Its dynamic driver “DD” features a rare liquid silicone diaphragm. The Yume is known for its spotless tonality with a frequency response fitting the Harman Target curve almost perfectly. Unfortunately, one earpiece had a a manufacturing flaw (possibly glue in the DD) so that proper auditioning and therefore a real review was impossible. So, please read the reviews of others while looking at the technical photos below.

Steve Tong, CEO of SeeAudio, responded rather quickly over Facebook Messenger and offered to re-imburse import fees and expenses. Excellent customer service. The SeeAudio Yume was kindly provided by HifiGo and I thank them for that.

The SeeAudio Yume comes with a quality 5N occ copper cable I know from the iBasso IT01, two sets of eartips, stickers, paperwork, and a metal storage case. The earpieces, although not the smallest, are light and comfortable. Isolation is good. The eartips are large enough for my ears canals. Everything works out of the box…other than the sound :).

The $300 Sennheiser IE 300 (above left) is the company’s latest mid-price iem to be released in the Americas and Europe in March 2021 (out in Asia since mid January 2021). It is based sonically on the $350 Sennheiser IE 400 PRO, the best of their PRO series imo…which is evident from their superimposed frequency responses graphs. Both are single-dynamic-driver earphones.

This photo series focuses on comparing the physical properties of both models’ earpieces. The PRO series has a proprietary connector whereas the new Sennheiser IE 300 features a recessed MMCX connector.

My detailed analysis and full review of the Sennheiser IE 300 to follow. You find my in-depth Sennheiser IE 400 PRO review here.

The Sennheiser IE 300 was kindly provided by Sennheiser USA/Canada for my review. Thank you very much.

The Moondrop Illumination is a single dynamic-driver earphone in the premium segment that is optically characterized by its gold coating. At an impedance of 25 Ω and a sensitivity of 124 dB/mW, the Moondrop Illumination is driven easily with any phone – but benefits greatly from a healthy source.

The Whizzer Kylin HE01 is a single dynamic-driver earphone with a rather particular rose-gold design that may polarize tastes. At an impedance is 18 Ω and a sensitivity of 112 dB/mW, the Whizzer Kylin HE01 is driven easily by any phone or dap. It comes with a fancy 5N OFC oxygen-free copper cable and 2 different sets of tips (“vocals” and “reference”). The Whizzer Kylin HE01 was provided unsolicited by the Whizzer Official Store and I think them for that. My full review:

The $159 KBEAR Believe is a technologically advanced single-dynamic-driver earphone. It joins the much more expensive Dunu Luna and Final Audio A8000 premium earphones with its pure Beryllium diaphragm. Beryllium is probably the stiffest diaphragm material that provides for the fastest possible driver.

At an impedance is 17 Ω and a sensitivity of 98 dB/mW, the KBEAR Believe can be driven with a phone but it probably benefits from amplifying. Here some technical photography showing the earphone’s physical features…which are essentially identical with the KBEAR Diamond. At the time of writing this, I had not listened to the KBEAR Believe yet. My full review is here.. Review unit of the KBEAR Believe was supplied by KBEAR Official Store – and I thank them very much.

The Moondrop SSP is the “sister spaceship” of the Moondrop SSR. Both are single-dynamic-driver earphones that share their tuning from the lower midrange up. The Moondrop SSP are obviously designed for people who found the Moondrop SSR too bright/aggressive sounding. Both earphones also share their physical features except the powder coating, which appears to be a bit more refined in the Moondrop SSP.

Here some technical photography showing the Moondrop SSP’s physical features. My full written review is here. The unit of the Moondrop SSP was supplied by Moondrop for my analysis – and I thank them very much.

The Knowledge Zenith KZ ASX is a 10 BA earphone in the $100 segment and KZ’s biggest gun so far in the ongoing budget driver war…literally…these earpieces are big oshis, although quite light.

Things that are interesting in the CCA CA16:

• Large body but smaller nozzles maybe there are people out there with large ears but small canals that will appreciate a nozzle not trying to enlarge your ear canals.
• The eartips are an uncommon U shape over a more V type, and bring the nozzle nearly flush to the end of the tip.

Spring 2 physical changes compared to the Spring 1:

• The nozzle angle is changed and feels more comfortable. Points forward more and less downward angle.
• The nozzle position is moved inward towards the center of the body by a millimeter or so. Hard to measure so a best guest.
• The nozzle screen holes are more open, less holes but larger openings
• The nozzle appears to be slightly shorter
• Body has a slight protrusion
• Cable is more pliable picture of Spring1, Spring 2 and a standard KZ/CCA cable.
