Instructions
Xbox 360
Connect your headset's cord into the headphone input on the Xbox controller.
Turn on the Xbox 360 with the Call of Duty 4 game disc in it.
Access the game and start playing. The headset should connect automatically once the match starts.
Speak into the microphone to talk to other players. Your headphones will allow you to hear what other players are saying.
PlayStation 3 Bluetooth Headset
Hold your Bluetooth's "Pairing" button down for several seconds until it begins blinking.
Access "Settings > Accessory Settings > Manage Bluetooth Devices" from the XMB home menu.
Select "Yes" when the PS3 asks you if you want to register the Bluetooth device.
Select "Start Scanning" for your PS3 to find your Bluetooth headset. Choose your headset when the PS3 finds it. If it asks you to enter a device key, type in "0000," as this is the default Bluetooth pairing code.
Navigate to the Call of Duty 4 game from your PS3 menu. When the game starts, you can speak to other players and hear what they're saying through your Bluetooth headset.
