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.
Balanced Armature
Westone’s balanced armature drivers are significantly more compact and eficient than traditional dynamic drivers. By 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 solutions.
EPIC Replaceable 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. The replaceable audiophile connector makes this solution conveniently user-removable and replaceable.
