Thanks so much for your help![/QUOTE]
If you do get the mixamp, you plug it into the USB of your Ps3. Then you plug the optical cable into the mixamp. Then you can plug any headphone with a 3.5 mm plug into a Y adapter ( two 3.5 mm jacks to one 3.5 mm plug ) with a clip on mic into the other 3.5 mm jack. This Y adapter then plugs into the headphone jack of the mixamp.
