Hi-Fi IEMs

Going a step above typical dynamic transducers, Westone is known for using balanced armature drivers to deliver Hi-Fi quality sound. These W40 IEMs open up a whole new world of audio precision and boast an impressive frequency range. Plus, they come with three interchangeable faceplates in black, blue, and red, so you can mix and match the aesthetic depending on your mood.

Note: This drop is limited to 19 units.

Sound Quality & Design

Inside the comfortable, lightweight housing, the W40 comes equipped with four balanced armature drivers that offer a level of clarity and noise isolation unheard of in most lower-priced IEMs. With the capability to fully support tunes that dip into a low range of 10 Hz all the way up to 18 kHz, the W40 gives you a unique listening experience that you’re sure to enjoy.
