MEST is our first hybrid headphones that use four different types of drivers-- bone conduction, EST, balanced armature, and dynamic.

There are many fun features the MEST, the newly designed bone conduction driver is definitely one of them. We spent four years in developing, configuring and tuning this uniquely designed bone conduction driver. The priority function of the bone conduction driver is to embellish the mid and treble. In the development phases, we found the bone conduction driver works remarkably well with EST and BA drivers in upper-mid and treble. The bone conduction driver with carbon fiber shell efficiently reduced the sharpness of EST drivers in treble without affecting transparency and treble energy. It also added a touch of sweetness in mid and smooth out the transition from mid to treble. With this bone conduction driver, MEST is able to deliver one of the most transparent and balanced sounds among our productions.

To know more about the bond conduction technology, here is an introduction:

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.

According to the frequency features of bone conduction driver, it can be used to embellish the vocals and instruments in mid and treble.

As a summary, MEST bone conduction technology has the following features:
  • No standalone sound tunnels for bone conduction drivers.
  • Sound can be heard by touching any parts of the shell.
  • Low-Voltage driving bone conduction driver
  • Resistant to treble noises
  • Low distortion
  • Smart fit and easy to be assembled
We will have a demo unit of MEST at 2020 CanJam NYC.

Drivers Configuration (per side):
1x Bone conduction driver to embellish the mid and treble.
2x EST drivers serve ultra-high frequency
2x High BA drivers.
2x Mid-high BA drivers.
1x Dynamic driver serves mid and bass.

Estimated MSRP:
$1399 for a universal fit
$1699 for a customized fit
Due to the special structure of MEST, we do not offer interchangeable reshell services between universal-fit and custom-fit. Making a customized MEST requires much more workforces than a universal MEST, thus we have to charge this $300 as a premium to cover additional costs. The custom-fit generally offers a larger touching area to your skin than universal-fit, thus the custom-fit helps the bone conduction driver to optimize its performance.
MEST is soon available at: https://shop.musicteck.com/collections/um-unique-melody

Subbed. Availability date? I assume MusicTeck will be carrying these. Might take a chance on a universal. Please post more pics soon. Even without the bone conduction driver there is a lot of tech crammed into these, curious about the size of the universal.

OH, It will be available after CanJam NYC at MusicTeck, there will be a demo unit at MusicTeck's show desk during the show as well! Sorry, I forgot to mention that in the content, thanks for the reminder.

I imagine the vibrations are so small as not to be felt.. What an interesting idea. I've heard a demo of the bone conducting running earphones by Aftershox at the running store and it's pretty wild how they work..

Wow, I have to admit I didn't see this one coming! Very curious indeed.

Man... you guys should be applauded for the boldness in research real new technology in this world of copy cats and all the same. Well done! :clap:

Seriously, even in a present period of a lot of innovation going on with IEM companies, you've managed to raise the bar again!
I salute you and the team! Very excited to hear more about this IEM (and hopefully actually hear it too, haha) :D

What's the expected frequency response of the treble for these?

I imagine the FR graphs for these will inevitably be deceptive, since the measuring hardware only mimics an air chamber, and has no mechanism to mimic the bone conduction.
True, though I am just curious about the treble region. Since crinacle started his crusade against the Sonion electret drivefs.
