MEST MKII

7 Traditional Acoustic Drivers + 1 dBC-s Dual Sides Bone Conduction System

In the year 2020, we have experienced too much, more than we can bear. We are delighted that the release of MEST could be a shining star breaks through the darkness for many audiophiles. At that time, we believed MEST is the finest quadbrid IEMs we can deliver to the community. Shortly afterward, MEST has become one of the most popular IEMs in the community. We are amazed by all the compliments we have received worldwide. However, we also generated some advice and some criticizes from our customers and the reviewers we have worked with.

In 2020, not very long after MEST was released. We built a text mining model, scraped the information from online reviews, and recorded every word from the video reviews to analyze the PROs and CONs of MEST. We also generated data from our customers among the Western community about their favorite music genres. Collected data from our distributors about the return cases and classified them by reasons... We have found some key points that we can improve on the MEST. There is only one goal for us--to design a perfect quadbrid IEMs, as close as it could be, and here is what we did on the MEST's successor-- MEST MKII.


  1. Brand New dBC-s Dual Sides Bone Conduction System with Newly Developed B2 Bone Conduction Driver-- A full range refinement provides fuller and bolder sounds in the lower frequency than the MEST. Further extended frequency response range from 20Hz to 70KHz.
  2. Upgraded Shell Design--3D printed semi-custom shells, one-piece carbon fiber material, lighter in weight, smaller in size, and more comfortable fit.
  3. Retuned towards Western Audiophiles' Tastes--With genres like Rock, Metal, Jazz, POP, EDM, Classical in mind, MEST MKII will provide a denser and fuller sound than the original MEST.
  4. Upgraded Stock Cable-- 4 cores, 24 AWG golden ratio upper purity OCC customized cable is comparable to most of the premium cables in the market.
  5. AZLA Sednaearfit Xelastec Ear Tips-- MEST MKII is the first IEMs with the AZLA Sednaearfit Xelastec ear tips in the stock package. Sednaearfit Xelastec is known as the most advanced PVC ear tips in the market; The data also reflected that it is the most recommended ear tip for the original MEST.
  6. Upgraded Packaging and Accessories-- Newly designed ESP gift box, MEC cable storage device...

MEST
World First 4-Way Quadbrid IEMS

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


MINI MEST

Open Air Balanced Armature Drivers X Bone Conduction Driver HIFI IEMs​



Technology

Bone Conduction Sonic Engine


Mini MEST succeed the bone conduction technology in the original MEST to embellish the mid and vocal performance.

Unlike the traditional tuning approach, bone conduction technology is able to transfer certain sound frequencies directly to your inner ears through the bones of the skull, processed by the inner shell vibration. The sonic path like this: Sonic signal—Bone conduction vibrator—bones of the skull—cochlea-- auditory nerve.

Knowles Custom-made Open-air Tubeless Balanced Armature Drivers

Mini MEST applied the custom-made open-air balanced armature drivers that are made by Knowles. These BA drivers have widely open front cavities that allow them to deliver sound without the inner tunnel (tubeless). The sound signature of open-air BA drivers is similar to dynamic drivers. It sounds more natural and forgiving than traditional BA drivers.

Exterior

High precision DLP shell printing: We applied dark blue resin shells on Mini MEST which make Mini MEST aesthetically beautiful and practically comfortable.

Two-color handmade carbon fiber faceplate: We used the classic carbon fiber faceplates on Mini MEST that were used on our flagships Mason V3+, Mentor V3+ and the original MEST.

Suitable Genres

We made some tuning adjustments on Mini MEST according to the customers' reviews of the original MEST. Mini MEST suits best for the following genres:

ACG/OST

Pop/Soul/Jazz/Blues/Rock

Acoustic/Classic

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..

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.
