Westone UM PRO 30 Universal-Fit In-Ear Earphone - Clear

  • New and improved triple balanced armature driver universal-fit in-ear monitors

  • Increased sonic detail and clarity with powerful lows, articulate mids and crystal-clear highs

  • Superior performance in a compact, lightweight package

  • Left and right earpiece responses matched to tight tolerance

  • Sound-isolating Star and True-Fit tips in multiple sizes ensure a comfortable custom fit



The new and improved UM Pro 30 features three proprietary balanced-armature drivers and a three-way passive crossover in an even more ergonomic and durable form factor. Each driver is designed to reproduce a specific part of the frequency range: lows, mids and highs. The UM Pro 30 was developed specifically to increase sonic detail and clarity, as the soundstage features powerful lows, articulate mids and crystal-clear highs that produce a performance, power and output perfect for any stage or venue.

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.

Three 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.
