Ear Force P21 gaming headset using mute

Hey StanClan,

The red/white splitter cable enables you to control the volume of the television and the headset independent of one another. If you turn down the volume on the television, you will still be able to hear the game sound through the headset. When using a headset, the TV volume typically only controls the headset volume if its connected using a 3.5mm cable through a headphone jack on the television itself.
