Westone True-Fit Technology

Fifty years experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece with optimum ergonomics and fit. The True-Fit sound port delivers maximum comfort and in-ear coupling for dynamic transfer of sound.

Balanced Armature Drivers

Operating on different functional principles than traditional dynamic, moving coil drivers, balanced armature drivers are significantly more compact and efficient, allowing for a more comfortable, electronically sensitive, and sonically accurate end result.

Acoustic Symmetry

The Westone W40 in-ear monitors feature left and right earpiece responses that are matched to an extraordinarily tight +/- 2dB tolerance. These tight responses deliver unparalleled balance and accuracy of sound-stage reproduction giving you the best sound quality possible.

EPIC MICS Cable

For the active user or mobile professional, Westone's MICS (Microphone In Control System) gives simple, one-button control for music playback plus answer/end call, voice control, and communication on most smartphones.
