Westone AC20 Balanced 2-Driver Musicians' Custom In-Ear Monitor

  • Dual Balanced Armature Drivers design

  • Isolation of up to 25dB ambient noise reduction

  • Specialized Cold Pour Acrylic technique for thicker and tougher shell

  • Removable Westone EPIC cable 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” clear acrylic body with the EPIC removable cable is exceptionally comfortable, provides up to 25dB of ambient noise reduction and is quite stealthy on stage.
