Westone UM Pro 50

The new and improved five-driver UM Pro 50 features five proprietary balanced-armature drivers with a three-way passive crossover and is the flagship IEM in Westone's line of universal-fit in-ear monitors. The sound stage of the UM Pro 50 is totally immersive, and delivers sonic detail that has to be heard to be believed.

Westone’s proprietary balanced armature drivers are significantly more compact and efficient than traditional dynamic drivers. Westone UM Pro 50 in-ear monitors provide enhanced sonic detail and frequency range that extends well beyond typical in-ear solutions and have become the gold standard in the industry.

Westone’s robust replaceable cable is 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.

True to sound.

Three Balanced Armature Drivers
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.

The high-tolerance fully reworked MMCX connectors ensure a reliable connection.
