Description

10-DRIVER CONFIGURATION & HYBRID BONE CONDUCTION TECHNOLOGY

MEST Jet Black uses a hybrid 10-driver configuration built
around Unique Melody’s Hybrid Bone Conduction System and Bone Conduction Crossover Technology. The complete setup consists of 1 Dynamic Driver, 4 Balanced Armature Drivers, 2 Electrostatic Tweeters, 2 Composite Balanced Armature Bone Conduction Drivers and 1 Piezoelectric Bone Conduction Driver

Rather than functioning as separate layers, each driver
system is integrated through a dedicated crossover architecture designed to improve coherence, spatial presentation and tonal balance across the entire frequency range.

The dynamic driver is responsible for low frequencies,
delivering deep sub-bass extension with controlled impact and physical presence. The balanced armature drivers handle the midrange and upper frequencies, focusing on vocal clarity, detail retrieval and instrument separation.

For the upper treble region, the dual electrostatic
tweeters provide additional air, openness, and extension, helping create the spacious presentation the MEST series is known for.

HYBRID BONE CONDUCTION DRIVER ARCHITECTURE

The Hybrid Bone Conduction System combines two composite
balanced armature bone conduction drivers with a dedicated piezoelectric bone conduction driver. Together, they enhance texture, staging, imaging, and dimensional depth by transmitting vibrations across different frequency ranges through the shell structure itself. Instead of artificially boosting detail, the system is designed to create a more natural and holographic listening
experience.

MASTERFULLY TUNED FOR BALANCE AND IMMERSION

MEST Jet Black was developed with a more balanced and
versatile tuning philosophy while preserving the expansive presentation that defines the MEST series.

The bass response is deep and authoritative while remaining
controlled and articulate. The midrange is positioned naturally with strong vocal presence and accurate timbre, allowing instruments and vocals to sound detailed without becoming overly analytical.

Treble remains airy and extended through the dual
electrostatic tweeters, adding openness and separation while maintaining a smooth overall presentation. Combined with the hybrid bone conduction system, the sound feels spacious, layered and highly immersive.

BLACK CERAMIC SHELLS WITH A REFINED JET BLACKFINISH

MEST Jet Black features a black ceramic shell construction
designed for durability, acoustic stability, and long-term comfort. The polished ceramic finish gives the monitor a clean and understated appearancewhile maintaining the premium craftsmanship associated with Unique Melody’s flagship designs. The shell incorporates a smooth ergonomic shape along with a
long-spout nozzle design for improved insertion depth, fit stability and passive isolation. Gold petal-style vent detailing is integrated into the shell while preserving the minimal and monochromatic Jet Black aesthetic.

UM JET LINK CUSTOM CABLE IN 4.4MM BALANCEDTERMINATION

This IEM comes exclusively with the UM Jet Link Custom
Cable in a 4.4mm balanced termination.

The Jet Link cable uses a 4-wire 26AWG OCC copper
configuration with a seven-core twisted structure designed to complement the spacious and resolving presentation of the MEST Jet Black.

Its lightweight construction improves flexibility and
long-term comfort during extended listening sessions, while the OCC copper conductor design helps maintain clarity, separation, and tonal balance throughout the frequency range.

Finished with a glossy PVC jacket and a 4.4mm balanced
termination, the Jet Link cable completes the MEST Jet Black as a fully integrated flagship setup
