Dual Conduction
UM has 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.
Four distinct exquisitely collocated drivers
4EST + 4 Balanced Armature Drivers + 1 Dynamic Driver+ 1 UM patent 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 midrange, 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.
Static enhancement, tuning optimisation
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.
UM patent Silver-Palladium Alloy Piezoelectric Bone Conduction Driver
The silver-palladium alloy piezoelectric bone conduction unit comprises 27 ceramic coatings, each measuring 23-25μm 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 980°C, 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.
Colour Selection
Available in both red and blue colourways, the metal frame of the MEST MKIII CF showcases carbon fiber shells and fruitwood faceplates. The blue variant emanates tranquility 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.
