How do i hook up a bluetooth to a ps3 to play online?

May be...

from the beginning thanks

I'm going to try this from the top of my head. Go to Settings, Accessory Settings, and look for either Sync Bluetooth Devices or Headset Settings. Then before you do anything else next, have your bluetooth headset in pair mode. Press and hold the power button on your headset for about 10-15 seconds. Depending on your headset, you should either get a solid colored light letting you know it's in pair mode. Then just hit the sync button and enter your password (it's 0000 ).

Go to Accessory Setting, go to manage Bluetooth. and click new and search make sure your bluetooth are in pairing mode. Once you find the bluetooth name click on it. and when it ask for the code write in 0000. that all

Then go back then go to audio device i think and put input and output whatever is on the list. like i think the bluetooth would say bluetooth. But mine say Wireless Headset, and change the Mic Level to 3 or 2 so they can hear you
