Instructions
Flip the game controller on its back, with the bottom of the device facing you.
Locate the small 3.5-millimeter jack on the bottom of the controller. This will correspond to the 3.5-millimeter plug on the headset.
Slide the 3.5-millimeter plug into the corresponding jack on the controller. Make sure the headset's plug seats fully into the jack.
Turn on the headset with the switch on the plug. Adjust the volume as needed to hear voices ad chat, using the volume slider on the plug.
