The 3.5mm audio cable plugs into your device and leverages the Cloud II's enhanced bass reproduction to deliver an intense audio experience. When used with the included USB-A advanced audio control box, you can initiate 7.1-channel virtual surround sound for an authentic and immersive gaming experience. An adjustable, noise-canceling microphone prevents distracting sounds from carrying through to your team, giving you a clean sounding vocal experience. If you feel like relaxing or if you are playing solo, detach the boom mic for headphone-only operation.
