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, you’ll discover a fusion of four distinct driver types. Low frequencies are handled by a dynamic driver, while mid and high BA drivers deliver frequencies.
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 23-25μm in thickness. To ensure optimal product performance, each bone conduction unit undergoes rigorous testing for capacitance, dielectric loss, displacement, and resonant frequency. The utilization 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.
Available in both red and blue color ways, 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 color 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 colors from the UM color plate and personalize the IEMs with a custom
logo. Additionally, it is also possible to customize the style and color 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 personalized 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
