Westone Custom-Fit Technology
Fully custom earpieces are cast, sculpted, and polished by hand from actual impressions of your ears, resulting in the best fit and acoustic seal possible.
Westone’s balanced armature driver is significantly more compact and efficient than a traditional dynamic driver. Westone monitors provide enhanced sonic detail and frequency range that extends well beyond typical in-ear solutions.
A body temperature-reactive, semisoft earpiece canal additive that stays firm at room temperature for ease of insertion and then softens at body temperature, allowing increased comfort and acoustic seal for incredible noise isolation.
Cold Pour Acrylic
Earpiece housings are cold-poured in acrylic for a thicker, more resilient acoustic enclosure. Expect increased durability, a more controlled response, and a lustrous appearance from this Westone technology.
With Westone’s Dual Bore technology, high and low frequency sound components are channeled through separate passages in the sound port and sum within your ear canal instead of the earpiece. The result is audibly more natural and provides a more convincing transition between frequency ranges.
EPIC Replaceable Cable
Westone’s robust EPIC cable is constructed of bifurcated, high-flex, ultra-low resistance tinsel wire, reinforced with a special aramid fiber, and braided for ultimate durability, acoustic transparency, and isolation from mechanical cable noise. The MMCX Audio™ connector makes this solution conveniently user replaceable.
