Bone conduction redefines audio with cutting-edge technology. No in-ear insertionโsound transmits directly through skull bones, keeping you aware of surroundings for safety. Lightweight and secure, it stays stable during workouts without discomfort. Clear sound, ergonomic design, perfect for commuting, sports, and the office. A smart blend of innovation and comfort, unlocking a freer way to listen.
True excellent sound quality never comes from the solitary efforts of a single driver, but rather from the harmonious coexistence of different drivers, such as dynamic, moving iron, and electrostatic, which combine to create an auditory feast beyond imagination. The dynamic driver delivers a warm, mellow sound, capturing the fullness and atmosphere of low frequencies. Every dive of the low frequencies is steady and powerful, restoring the most authentic warmth of the sound. The moving iron driver is precise and delicate, unlocking the clarity and resolution of mid-to-high frequencies. The breath of vocals and the overtones of instruments are clearly distinguishable, bidding farewell to blurriness and turbidity. The electrostatic driver brings out every detail, fully extending the high frequencies, creating an ethereal and transparent sound that is not harsh, allowing every sound detail to be gently captured.


Dual Conduction
UM h6as embraced a philosophy of relentless innovation and ongoing advancement ever since its inception. Devoting significant resources and effort to technology and research and development, we have dedicated nearly a decade to perfecting our IEM bone conduction technology. The result is a dual-conduction system meticulously engineered to deliver unparalleled sound quality
4EST+4Balanced Armature Drivers+1Dynamic Driver+1 UM patent Silver-Palladium Alloy Piezoelectric Bone Conduction Driver With the MEST MKIII CF, youโll discover a fusion of four distinct driver types. Low frequencies are handled by a dynamic driver, while mid and high BA drivers deliver frequencies.

Silver-Palladium Alloy Piezoelectric Bone Conduction Driver
With the MEST MKIII CF, you’ll discover a fusion of four distinct driver types. Low frequencies are handled by a dynamic driver, while mid and high frequencies are delivered by BA drivers. Ultra-high frequencies are taken care of by an electrostatic driver, and the silver-palladium alloy piezoelectric bone conduction ensures complete frequency compensation. The outcome is exceptional layering and separation, delivering holographic imaging and captivating 3D presentation. Experience the profound resonance of impactful bass, the rich texture of the mid range, and the vivid brilliance of beautiful treble, reflected with precision and clarity. The MEST MKIII CF stands as a groundbreaking achievement in the realm of IEMs, captivating listeners with its flawless tuning and innovative driver configuration. At the core of its cohesiveness lies the silver-palladium alloy piezoelectric bone conduction driver, harnessing the bone conduction effect across the entire frequency spectrum. This integration results in a precisely balanced and immersive sound, offering a comprehensive and remarkable audio experience.

By opting for an electrostatic driver, we enhance both the frequency response range and treble extension. This choice empowers the ear to capture intricate details of sounds that are typically imperceptible. Equipped with four electrostatic drivers, the MEST MKIII CF delivers elevated sensitivity, minimal distortion, intricate detailing, and an enhanced perception of spaciousness.
Through its emphasis on bass details and quantity, the MEST MKIII CF accentuates critical nuances and imparts a vibrant and energetically rich sound. The MEST MKIII CF employs bone conduction technology, harnessing the lateral vibrations of the cavity to directly transmit sound to the inner ear through
contact with the skull, bypassing the traditional nozzle pathway. With an exceptional frequency response
range spanning from 20Hz to 70kHz, the MEST MKIII CF exhibits remarkable versatility. The dynamic and
BA drivers handle the 20Hz to 20kHz range, while the electrostatic drivers excel in the 10kHz to 70kHz
range. The silver palladium alloy bone conduction system provides full frequency compensation between
500Hz to 16kHz. Through the harmonious interplay of air transmission and vibration transmission, the MEST MKIII CF delivers an entirely new dimension of sound quality. With its innovative and competitive features, the MEST MKIII CF stands out as a true audio marvel.
The silver-palladium alloy piezoelectric bone conduction unit comprises 27 ceramic coatings, each measuring 23-25ฮผm in thickness. To ensure optimal product performance, each bone conduction unit undergoes rigorous testing for capacitance, dielectric loss, displacement, and resonant frequency. The utilisation of a high-temperature resistant conductive
palladium paste allows for ceramics to be sintered at 980ยฐC, ensuring exceptional performance and reliability. In contrast to the double vibrating bone conduction with 14 ceramic coatings, the silver-palladium alloy piezoelectric bone conduction driver offers multiple layers and increased thickness, enhancing the vibrational efficacy of bone conduction and delivering a distinct and superior sound experience.

Integrating all dividers on a gold-plated PCB board, the MEST MKIII CF achieves excellent stability and consistency while enhancing conductivity with its gold-plated surface. The circuit board incorporates high-precision components to ensure remarkable
sound quality and robust stability.

Available in both red and blue colour ways, the metal frame of the MEST MKIII CF showcases carbon fibre shells and fruitwood faceplates. The blue variant emanates tranquillity and elegance, while
the red variant exudes passion and liveliness. Each colour possesses its own distinct qualities, evoking a sense of serenity or dynamism, relaxation or intensity.
The MEST MKIII CF is offered in two variations: a universal fit and a custom fit. The custom fit option provides the freedom to choose colours from the UM colour plate and personalise the IEMs with a custom
logo. Additionally, it is also possible to customise the style and colour to match that of the universal fit version.
The MEST MKIII CF incorporates newly designed cobalt blue and melon red shielding cables. These cables are crafted with a pure 4-core OCC copper construction, featuring a nylon sleeve and an environmentally friendly soft PVC coating. With a 26AWG gauge, these cables offer ultra-low resistance and minimal distortion, resulting in the utmost clarity and a remarkably clean audio backdrop. Terminals are available in 2.5mm, 3.5mm, 4.4mm.

Crafted from a silicone material akin to that of baby pacifiers, UM Transparent Ear Tips are exquisitely
soft and elastic, providing a snug fit close to the ear. These ear tips are available in two variants: the perforated Open Tips and the non-perforated Petal Tips, allowing for personalised replacements based on individual preferences. The Open Tips feature six edge holes, ensuring breathability and alleviating pressure. With their remarkable comfort, these ear tips can be worn for extended periods while still maintaining awareness of ambient sounds
