The wire coming from the left ear cup contains an in-line volume adjuster that allows you to separately tune each audio channel. From here you can connect an Xbox 360 controller (with an included wire) and then adjust the microphone volume as desired. When you're ready to fire off orders, unveil the hidden, noise-canceling mic boom to strategize clearly with team members. Adjust audio levels using in-line volume and mic-mute controls. For starters the speakers are not placed in the ear cups. The speakers are placed above your head in the bridge of the headphone.
