MEST Bone Conduction Technology
Diagram 1: MEST Exploded Views
Diagram 2:The faceplates of the headphones are specially designed according to the structure of the bone conduction drivers. Bone conduction driver delivers signals by vibrating the faceplate. Then the signals are passed to the carbon fiber shell and finally delivered to your inner ear.
Diagram 3: The bone conduction drivers are made by metal vibration pieces that are covered by piezoelectric ceramics. The ceramic layers will bend the metal vibration pieces to make micro-vibrations according to the changes of input alternating voltage.
Diagram 4: The frequency curve of the bone conduction driver along with the shell on HATS.
Pros: Wide, deep, tall soundstage. Rich, layered bass. Detailed, extended, smooth highs. Comfortable fit. Accurate timbre, rich texture and tone. Big, bold sound with tons of detail, layering and slam. Rich, detailed, layered mids.
Cons: Need to be comfortable with W sound signature, tho brain burn may win you over! Mids can 'possibly' be too forward, but very dependent on tips and cable!
This IEM Is one of the best I have heard! The details and layering and sound stage is Fantastic!
I think the title says it all. The MEST is my favorite IEM and I own some IEMs that cost more than this, namely, Sony IER-Z1R and Empire Ears Legend X. I am selling off my IER-Z1R because I see no point in keeping it when I have the MEST, which says a lot about this IEM. This is indeed my first tribrid and I have never heard anything this resolving and clean. The bass is exactly on point - not obscenely exaggerated, nor anemic in any way - it's just perfect. I love it. In many TOTL IEMs you'll find a thin and recessed mid range - not here. I am not sure how the bone conduction driver does this but it is magic. Full bodied and clear. This is like listening to the singer in an great stage (which is waay better than having the vocalist signing right in front of you). That is another way of saying, the soundstage is expansive. The "air" and the treble definition is what makes the MEST the most special IEM in my collection. I think this is the best IEM in the $1200 to $3000 range. I just cannot say enough good things about it. You really need to hear this even if you have all the big and shiny CA earphones and other TOTLs. This is a game-changer!
This sound like a terrific IEM
What is the best DAP to pair the MEST with?
Would it work with a Shanling M6 or Fiio M11 PRO?
First off Andrew at MusicTek is extremely helpful and familiar with many products. The MEST sounds Fantastic, an open spacious sound is to be expected. Lots of detail going on that one might not notice before prior to these bad boys. These are very musical and are a welcome to my small collection, in the top three easily in terms of pure Musical enjoyment!. build quality is on par with some of the very best and pricier IEMs. You can pay more and surely get Less. I don’t want to get caught up in the technicalities I rather spend my time listening to these MEST !! Endgame for many.
Listened to a lot (a whole lot) of IEM's at Can Jam- kept coming back to listen to these. Low end is tight and deep, Mid range is buttery and high end is to die for. Beautiful sound stage, isolate external noise extremely well and they fit me great to boot. I listen through my Ibasso DX220 AMP1 mk2. Pure Heaven. Thanks to Andrew for getting them to me so quickly.
