If you mean a ps3 wireless headset, then i could help you.
Goto acseesory setting ( spelling ) and goto install Bluetooth device. At first this could be very annoying ( trust me ) It'll ask you if you want to start scanning... Make sure the device is offline!!! When you start scanning, hold down the power button until its done scanning. It'll ask you if you want it, click yes.. It will then ask you for a pin code.
My lil' bro did this, im not sure if its on the box you opened it from or you make your own. MAKE SURE TO REMEMBER IT! If it goes defective ( my does every week or so ) Then you must repeat the process with the same pin code! REMEMBER!
Ok, after words it will tell you that its registerd, keep searching the acsesorys section util you find a button that says wireless headset with a blue dot next to it. I think its sound or something. Theres 2 option, change the 1st one to the one of the blue dot. Then just turn ur mic on and ur set.
