The new and improved dual driver, UM Pro 20 features two proprietary balanced-armature drivers, with a two-way passive crossover in an even more ergonomic and durable form factor. Developed to reproduce a large and enveloping sound, the UM Pro 20 has the range and output for any stage condition. The dual balanced-armature driver design delivers robust low end and crystal clear highs, with all the detail and nuance that professional musicians have come to expect from a Westone in-ear monitor.
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.
Two 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.
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.
