With its thunderous lows combined with a detailed midrange and articulate highs in a balanced and harmonious presentation, the UM Pro 50 meets the demands of the most discerning musician or music lover.

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.

Designed and Engineered in Colorado, USA: Meticulously designed by a staff of dedicated artisans and lab techs based in the USA.
