NEW TECHNIQUE OF BONE CONDUCTION

MEXT, a new high-performance product developed by UM, is being launched by the company after years of technical research. New bone conduction technology provides a revolutionary breathtaking experience. Due to its dynamic, balanced armature, and OBC coil bone conduction drivers, this IEM can deliver sound both through air transmission and bone conduction, creating a sensation of space and vibration all around. From single or dual sides bone conduction to the currently patented OBC technology, UM is always a leader in the audio industry. Techniques such as these can be imitated, but the sound produced by UM cannot be matched.

1 COIL BONE CONDUCTION + 1DYNAMIC +4 BALANCE ARMATURE

A MEXT driver consists of one coil Original Bone Conduction, one dynamic and four Balance Armature drivers. In addition to a smooth transition and rich sound, the OBC driver is able to reach up to 200Hz to 7000Hz in sound frequency with its highest sensitivity at 400Hz, 79m·N. The MEXT's sound delivers an impressive punch and is more impactful at low frequencies thanks to the OBC driver. Along with the perfect performance of the combination of dynamic and balanced armature drivers, the MEXT can lend itself to be exacting and precise or smooth and gentle when the music calls for it.

THE ORIGINAL SONIC WAVE SYSTEM BY UNIQUE MELODY

OBC, namely Original Bone Conduction, is known as coil bone conduction driver. From the first generation of the MEST, UM is the first audio company who applies the technology of bone conduction to high-end in ear headphones by combining air conduction with bone conduction to achieve a unique sound experience and quality.

ILLUSTRATION OF OBC DRIVERS

This IEM Consisted of high magnetic N52 neodymium magnet and high toughness vibrating steel sheet and high purity copper coil, the OBC driver is made using the technology of low-temperature welding. High quality neodymium magnet is produced by continuous debugging and sifting. The coil bone conduction driver is lightweight, wear-resistant and offers excellent conduction, indicated by its incredibly high yield rate, stability, and accuracy. UM has a keen eye for detail, so each OBC is excellently finished off.

ERGONOMIC DESIGN

Deeper is the OBC driver placed inside the headphone, close to the ear bone. Giving MEXT the advantage to instantaneously sense the vibration of sound wave. Moderate in physical vibration, it’s comfortable even for long time wearing. Small in size, comfort in wearing, MEXT has an ergonomic design to make it easier to suit different types of customers.

CUSTOM EARPHONE CABLE

MEXT is paired with UM Copper M1 custom cable manufactured by PW Audio. It is soft and exquisite. The black shells of MEXT and the black shield of M1 complement each other perfectly, exuding a concise appearance. Using OFHC copper wires create a natural and smooth sound. Partnered with the instant vibration of an OBC driver, the MEXT sounds like mild, fine, and smooth.
