Mest Jet Black

Mest Jet Black is a product from the UM MEST series. It continues the series' signature four-driver hybrid configuration while making significant breakthroughs in driver technology and tuning. For the first time, it features a ceramic shell and the newly developed Hybrid Bone Conduction system, along with an innovative bone conduction crossover technology. Listening to the Mest Jet Black is an experience of solemn power and unparalleled sensation.

Innovative Material Selection

Following the philosophy of ultimate pursuit and meticulous craftsmanship, we chose a black ceramic shell for the Mest Jet Black. The ceramic shell is delicate, with a smooth, jade-like texture, earning it the name "Black Jade".

The manufacturing process for the ceramic shell and faceplate is extremely complex. It begins with zirconia powder processing, followed by sintering at 1600°C and multiple intricate procedures. The final product undergoes precise manual refinement and high-precision machining to achieve its stunningly refined texture. During the sintering process, the earphone size shrinks by approximately one-third, requiring rigorous verification and testing of design tolerances and final dimensions. Due to the high hardness of ceramic, diamond-tipped tools are necessary for milling, making the final processing stage highly challenging.

Reasons for Choosing a Ceramic Shell:

• Enhanced Acoustic Performance – The high density of ceramic provides Mest Jet Black with superior acoustic properties, ensuring more stable sound transmission while reducing distortion and unwanted noise.
• Excellent Sound Isolation – The ceramic shell effectively blocks external noise, allowing for a pure and immersive listening experience.
• Exceptional Durability and Scratch Resistance – The material maintains its pristine appearance even after prolonged use.
• Strong Antibacterial Properties – Compared to traditional materials, ceramic is environmentally friendly, recyclable, and hygienic.
• Smooth, Comfortable Texture – The warm and refined feel of ceramic enhances wearing comfort.
