The new Westone UM1 uses a specially-tuned proprietary, balanced-armature driver to deliver extraordinary detail and clarity. The full-range balanced-armature driver delivers a dynamic and articulate soundstage, with all the detail and clarity musicians have come to expect from a professional in-ear monitor, all at a price that is accessible to aspiring musicians and music lovers alike. The Westone UM1 incorporates all the innovations and expertise that Westone has developed in over 60 years of designing and manufacturing products for the human ear. The compact, low-profile, ergonomic design is comfortable, and can be worn for hours and hours. Westone’s proprietary silicone and comfort foam ear-tips are provided in 5 different sizes, and enhance the performance of our In-Ear Musicians’ Monitors by providing superior noise isolation and ensuring a superb fit. Ambient sound levels are reduced an average of 25 dB, which makes the UM1 ideal for use onstage or in other noisy environments.
