Westone, the leader in high performance audio and in-ear monitoring technology, will be demonstrating the Signature Series UM Pro 50 for the first time at NAMM (National Association of Music Merchants trade show.) The UM Pro Series 50 is the first signature model of the acclaimed Westone UM Series. The Signature Series brings superior sound for the stage or studio. Each unit is individually handcrafted in Colorado Springs, USA. The UM Pro 50 is the first professional universal-fit headphone from Westone with five balanced armature drivers per unit, delivering reference level sound and isolation for the stage or studio.

The UM Pro 50 combines five balanced armature drivers with a sophisticated three-way passive crossover network, providing enhanced sonic detail and a frequency range that extend well beyond typical in-ear solutions. Like every UM Pro Series model, the UM Pro 50 features Westone's robust EPIC replaceable cable, constructed of 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. The new audiophile connector makes this cable solution conveniently user-removable, upgradeable and replaceable with a number of new and current Westone cable solutions.With Westone True-Fit technology, Westone combines 55 years of experience with in-ear applications that yield a low-profile, lightweight, universal earpiece which delivers maximum comfort and in-ear coupling for dynamic music monitoring.
