    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.

    One of my favorites

    The only problem i have is that the nozzle is a little big on the IEMS but i managed to find eartips that fit well, once that was taken care of, i could enjoy them to the fullest, one of the best head-fi items i have in my collection, also the support was great 10/10!

    My MEST is Best

    With the purchase of the Mest I believe I have reached my end game. The sound is superb better then I had hoped for leaving me no reason to purchase additional ear gear.

    My endgame

    Having tried literally hundreds of different IEMs, this is the one I don't think I could be without.

    My search is over!

    After thinking my Fearless Audio S8Freedom would be my end game, thought I would research what others consider possible TOTL iem’s. Spent the last 6 months researching a select half dozen I would consider purchasing, reading everything I could find on them, discarding those that mor3 than likely would ultimately nor fit my sound preference, and finally came up with two I liked the best given all info found. Decided to take a chance on the UM MEST as bone conduction intrigued me. I am so happy I did and am totally satisfied. No regrets on purchasing others on my list quite a bit more expensive. Blown away by the details and imaging particularly. Never really liked an IEM with a dynamic driver, or just got used to all BA driver iem’s, but am loving the bass on my MEST. Mids are more pronounced than anything I’ve heard before. And especially for my ears it seems, no issues with higher frequencies. Need to do more research on this bone conduction. They do fit my ears, which are somewhat on the smaller side, rather well. Have found, as others, that tip preference is very important to a sound one prefers, but no problem really. Will be thoroughly enjoying going through my entire music library once again, but I believe my search for an end game IEM is over, finally.
