Custom fit, cold-pour acrylic delivers amazing fit with dual-driver design. The AC Series breaks new ground in performance, quality, and value. Handcrafted in the same custom lab alongside the revered Westone ES Series, the AC Series uses balanced armature drivers to accurately reproduce your live performance. The “cold pour” acrylic body with the EPIC replaceable cable is exceptionally comfortable, provides up to 25dB of ambient noise reduction, and is quite stealthy on stage. Recommended for emerging artists and worship teams.
