General Information
Dual conduction system (air conduction + bone conduction)
Continuous growth in innovation has been the philosophy that UM has followed since its establishment. UM has invested a lot of money and energy in technology and research and development. As early as ten years ago, we began to study the use of bone conduction in IEM, so that the dual conduction system can play a better sound quality performance. This is a process of continuous exploration, and the MEST series is a successful proof.
Four units, exquisite collocation
4 kinds of unit combinations, moving coil is responsible for low frequency, moving iron is responsible for medium and high frequency, static is responsible for ultra high frequency, and silver palladium alloy piezoelectric bone conduction provides full frequency compensation. Superb layering and separation, from holographic imaging to 3D presentation, fully embodies every impactful bass, textured midrange, and beautiful treble. MEST MKIII CF is a milestone progress of IEM. Its impeccable tuning and collocation, high-level imaging, amazing hearing. Silver-palladium alloy piezoelectric bone conduction is the key to bringing cohesion. Benefiting from the impact of bone conduction on all frequency bands, MEST MKIII CF forms just the right thickness and density of sound, allowing you to experience a comfortable rhythm and wonderful sound quality in all directions.
Electrostatic enhancement, tuning optimization
The electrostatic unit is selected to increase the frequency response range and expand the treble, so that the ear can capture the sound details that cannot be felt normally.
4 electrostatic units make the sound of MEST MKIII CF more sensitive, with low distortion rate, richer details and stronger sense of air.
On the basis of the original tuning, more attention is paid to the sense of low-frequency volume and details, and the sensitive points are highlighted to make the sound richer and full of inspiration.
MEST MKIII CF uses bone conduction to vibrate the sound from the inside of the cavity, and directly transmits the sound to the inner ear by contacting the skull without going through the sound outlet. The frequency response range of MEST MKIII CF can reach 20Hz to 70kHz, ultra-wide frequency response. Among them, the moving coil and moving iron are responsible for 20Hz to 20kHz, the electrostatic unit is responsible for 10kHz to 70kHz, and the silver-palladium alloy bone conduction is responsible for full-frequency compensation of 500Hz to 16kHz. Air conduction and bone conduction interact to create a new sound quality, MEST MKIII CF is uniquely innovative and competitive.
UM patent silver-palladium alloy piezoelectric bone conduction
The silver-palladium alloy piezoelectric bone conduction unit has a total of 27 layers of ceramic coating, and each layer of ceramic is 23-25 μm.
Each bone conduction unit has been strictly tested for capacitance value, dielectric loss, displacement and resonance frequency. The use of high temperature resistant conductive palladium paste enables ceramics to be sintered at 980°, which fully guarantees product performance. Compared with the 14-layer ceramic coating with double vibration bone conduction, silver-palladium alloy piezoelectric bone conduction has the characteristics of more layers and higher thickness, which improves the bone conduction vibration effect with high quality and makes the sound effect more distinctive.
MEST MKIII CF adds a gold-plated PCB version, which integrates all frequency dividers on the circuit board, with good stability and consistency, and gold-plated for better conductivity. High-precision components are used on the circuit board to ensure good sound quality and strong stability.
Red and blue optional
Available in red and blue colors, the metal middle frame is inlaid with a carbon fiber cavity and a fruit wood panel. Blue, quiet and elegant, red, enthusiasm and vitality. One static and one movement, one piece and one relaxation, each has its own characteristics.
MEST MKIII CF has two types: male model and custom model. The custom model can be freely matched with the colors on the UM color board and customized personalized logo. You can also customize the same style and color as the male model.
