UM Pro 50 Earphones Features

Westone True-Fit Technology
50+ years' experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece which delivers maximum comfort and in-ear coupling for dynamic transfer of sound.

Five Balanced Armature Drivers
Westone's proprietary balanced armature drivers are significantly more compact and efficient than traditional dynamic drivers. As the pioneers in combining multiple balanced armature drivers with sophisticated crossover networks, Westone monitors provide enhanced sonic detail and frequency range that extends well beyond typical in-ear monitors.

MMCX Audio Twisted Cable
Westone's robust replaceable cable is constructed of bifurcated, high-flex, ultra-low resistance tensile wire, reinforced with a special aramid fiber, and braided for ultimate durability, acoustic transparency, and isolation from mechanical cable noise. Equipped with Westone's proprietary, high tolerance MMCX connectors ensure a reliable connection every time.

Acoustic Symmetry
Left and right earpiece responses are matched to an extremely tight 3dB tolerance.
