I want a Mest mk1 but could the Mest mk2 or mk3 be eq'd to sound like the mk1. Let me know if you have tried this.

Hello headfiers! I've seek for a thread about (good) bone conduction earphones and can't find any.

This isn't about single bone conduction driver sport earbuds or wtv, it's about hybrid, tribrid and quad drivers IEM with bone conduction.

I feel we are into a momentum right now and that 2024 will bring use more bone conduction configuration tech.

And yes, CHifi might take a big part in this.

Let's begin by my humble collection, i own 4 IEMs with BC.

Unique Melody Mest MK3 (!DD+4BA+4EST+1 wide band BC)
(my end game IEM and no1 reason of my BC obsession)
https://www.head-fi.org/showcase/unique-melody-mest-mkiii-cf.26526/reviews#review-31285

Pros:
-superhuman resolution
-ultra precise next level imaging
-holographic multi layered soundstage
-fast punchy textured bass with excellent definition
-excellent sub and mid bass layering and resolution
-vast open mids with fully covered sound info
-fowards vocal, piano and main instrument
-rich in details texture yet transparent enough too
-edgy definition, no contour blur
-fast snappy ultra controlled attack
-infinite number of micro details: effortless way
-treble sparkle-brillance and long clean natural resonance
-even silence have resolution info
-can deal and even refresh any music you throw at
-neutral with slight bass boost, lively and crisp way
-non fatiguing tx to BC driver
-small and light housing is very comfortable
-intense noise isolation
-strange to say but: good sound value even at this price!

Cons:
-those who love thick colored mids timbre might find it slightly thin
-at VERY high volume we can have extra fuzzy resonance in upper mids with soprano singer loud passage
-the bass impact isn't vast in headroom and not super weighty or chunky (not for basshead)
-treble info might be overwhelming for some
-cable is absurdly bulky

UM Mext (1DD+4BA+1 coil BC)
https://www.head-fi.org/showcase/un...of-bone-conduction.25639/reviews#review-28827

Pros:
-Smooth crisp and immersive musicality
-Exceptional resolution
-Organically Cohesive tribrid tuning
-Richly detailed mid-range with focused presence
-Fast snappy treble with tremendous micro-details amount
-Nice transparency
-3D spatiality with fully present center stage
-Great imaging-layering
-Realist timbre
-Excellent all-arounder (even including gaming and movie watching)
-authoritative bass with tactile weight
-their nothing that sound like the Mext
-more musical than Mest MK2 (subjective)
-good cable, nice case and very welcome Azla eartips

Cons:
-bass is a bit warm in definition and resolution compared to mids-treble
-lows are mid bass focus, lacking deep linear extension
-timbre is a hint compressed in density
-lack of air in overall spatiality
-capricious fitting to achieve supreme sound experience
-overly tight 2pin connector with rounded edge

BQEYZ Winter (1DD+1piezo BC for treble)
https://www.head-fi.org/showcase/bqeyz-winter.26039/reviews

Bright neutral with vivid yet non fatiguing upper treble, very snappy and clean in micro details with extra layering from BC. Mids aren't the most pleasant and sub bass is roll off.

BQEYZ Wind (1 coil BC for bass-mids+10mm dual cavity DD)
https://www.head-fi.org/showcase/bqeyz-wind.26715/reviews#review-31923

Ok, i do adore those quite alot and its the go too for plain mid centric BC hybrid, in that regard, it surpass UM MK3 which have a bit more ''noisy'' less colored with appealing warmth timbre....its the most lush and musical IEM of the bunch here to my ears....your drowning into mids sweetness and bass line are delivered in uniquely layered way, super smooth yet rich in texture. everything is mellow and immersive with those and the price is so competitive....yet, the trade off is in uppe treble and sparkle as well as clean air, the BC do add a macro dynamic warmth and smoothen bass impact roundness. anyway, these are a must have for vocal and mid range lover, it's ultra HD mids here, non bright harsh way....

Pros:
-Unique mid centric tonality
-excellent bass layering
-deep vibrant dense sub bass
-round dynamic mid bass
-incredible mid range resolution with full presence
-organic cohesion between bone conduction and dynamic driver
-end game vocal specialist
-numerous micro details and sound layers extraction from BC that wasn't perceivable with normal hearing
-warm overall macro dynamic
-nothing sound like the Wind its GREAT
-excellent craftmanship
-great 4.4 balanced cable
-good accessories
-good sound value (like having a darker mid centric UM Mext for 1/4 of the price)

Cons:
-power hungry
-bass separation isn't crisp or clean, it's all about layering
-treble lack sparkle and air and isn't extracting as much details as mid range
-half open back mean sound leakage





So, the goal of the thread is to share impressions and news as well as our though about bone conduction tech. I do feel it open new doors in acoustic experience that only this kind of IEM can achieve, mixing air and bone vibration transmission can bypass compromise of air transmission....in fact i would need to do drawing to explain the psychoacoustic experience these deliver...its near esoteric!

Right now my eye is one the BGVP DMA, its the very first sub-1000$ tribrid with BC i think, but it's a ''sonion bc vibator'', different from those above.



i think its this one:https://www.sonion.com/wp-content/uploads/37AAX007_A-3019972.pdf

its not a wide range BC, more a mid range that top around 2-4khz....

the big deal is the price: 300$

if well tuned, this might offer incredible sound value.

Do you have good bone conduction on all these iems?

I have awakened from a long headfi slumber to join this thread. Blind bought the BQEYZ Wind a few months ago and feel like there is no going back.

Is the Bgvp DMA worth it if I have the wind? I might just have to blind buy them since I absolutely love the Wind and am. trying to keep an eye on any new BC (preferably low/mid bc or full range) on the horizon.

 

[Tamizhan]

I can see quite a few here liking Wind. I'm very much considering it, but there are few negative reviews out there who say it's poor and terrible.



Even then, I'll be going ahead with the wind. If you guys can check these and tell that if it's done in poor taste or not.

The Wind is tricky - the DD is tuned quite bright, making it potentially fatiguing if you turn up the volume enough to get the most from the BC. But the texture and sense of space really make it an interesting IEM.

Unless you like a lot of spice in your treble, you might want to put an audio filter over the Wind’s nozzles. I use quite a thick one (500 grade) as I prefer soft treble, but 200-300 should do for most people. I believe the nozzles are 4.8mm in diameter, and the filters should only be a few dollars (or try the filters included with some IEMs such as the Tanya, Olina or Sonus). With the mod, I really enjoy the Wind.

 

[SciOC]

Bright? I don't get bright at all from the wind but then again I'm saying that as a BQEYZ set. My other BQEYZ are all brighter than the wind.

You do need to listen loud. The wind seems like it'd be pretty pointless if you listen at lower volumes. I don't pretend to know what reviewers are thinking or doing nor do I put any faith in random reviews. I own a lot of sets, and the wind is currently my favorite going on several months now. If you're looking for the technical best sound quality the wind probably isn't it, but the bone conductor adds a level of impact you can't really get anywhere else aside from maybe the bgvp DMA. It's a bit like 5 channel surround sound for the first time if You've been used to 2 channel. It's just different with an obvious superiority in some respects.

Do you guys actually hear a difference with the bone conducting driver? I have a mest 2 and while its an amazing iem, it doesnt really sound that different from other I have. Is there something special I need to hear or is it just me?

I remember watching a mext video where they said Mext was easier to differentiate the BC as opposed to Mest which was harder to hear it

It was a paul wasabii video I think and he recommended a song from it that shook the BC weirdly

Hi guys, here is my review of the BQEYZ Wind that I just published:



I also have a written review over on the Head-Fi showcase: https://www.head-fi.org/showcase/bqeyz-wind.26715/reviews#review-33247

Also, I want to mention that I don't really think the BC driver makes much of a difference on the Wind. Just something to keep in mind when you buy it.

 

[MidnightSun]

I wanted to ask you guys who heard the Wind: Compared to its FR graph, how different is their actual reproduction? I wouldn't pay a cent for a too early 10dB ear gain, but if the BC driver indeed puts some meat on the bone in the lows, it might be a more forgiving experience. Similarly, the MEST series might be great with the BC, but not my cup of tea without -- on paper.

initial impression while auditioning at canjam was it’s bright and hash.
some will like this type of sound.
change wind to use OCC and everything else calms down. u can try this.

I didn't realize the kinera celest plutus beast existed. 1 low end BC, 1 ba, 1 mini planar. Blind ordered them. Hard to pass at $90. Anyone tried these?

Edit:I see in the thread now.... Sounds like it might be neat but probably inferior to the wind. Guess I'll find out. Variety is the spice of life.

Plutus beast:

8 kHz is a coupler artefact peak



Pros:
Generously accessorized
Elegant shells
Decent comfort
Easily driven
Unique head-bopping bombastic signature
One for bassheads
Non-fatiguing treble

Cons:
Low impedance may make source pairing tricky
Slight driver flex
Average resolution
Occasional shoutiness at upper mids if used at louder volumes (Fletcher Munson curve)
Big bass may not suit some music genres


3 - 3.5/5, nothing special IMO.

Just got my set, burning in as we speak. Listened for a second and the bass is pretty head rattling with the MSEB/EQ settings I've been using on the wind.


I don't really have initial impressions of the sound outside of that and that they're very sensitive and much easier to drive than the wind.

Definitely good accessories and case for sub $100 set, with the huge exception of the crap cable. Oh well, at least it came with a 4.4mm cable, a crappy 4.4mm cable is more useful to me than a nice 3.5mm cable.

Do we know what drivers are covering the bass regions? I'd suspect it's the mini planar and BC, overlapping, but I've not seen definitive info anywhere about the cutoffs.

Yeah it is quite basshead.

Supposedly the square planar driver is marketed to be full range according to their site, with some contribution from the BC: https://www.kineraaudio.com/product/celest-plutus-beast
