Introduction

Westone is one of the biggest brands in the earphone industry. Their latest set of in-ears is an upgraded version of their highly acclaimed Westone 4 in-ears. Dubbed the Westone 4R this new version comes with a user replaceable cable system and has more tightly matched drivers. The model will be introduced at $50 more than the original 4s, meaning you have to be willing to spend $499 plus shipping for a set of these earphones. The 4Rs use the same driver setup as the old 4s (two bass, one mid, one treble driver). Nothing has changed on the cross-over side so it is pretty much the same internals as the original 4s, besides the better matched drivers.

The replaceable cable allows you to upgrade to one that suits your purpose best. There will be versions with podded microphone and remote for i-devices. You could also opt to fit the Westone 4Rs with a higher quality aftermarket cable or simply one that is longer than the normal cable. In this review we focus on the performance with the regular cable and we see how the 4Rs' performance scales when run in balanced mode through a Whiplash Audio TWAg v2 cable.
