sorry if this has been asked before, but couldn't find this specifically in search. i just got a ps3 and want to play car games like gt5, etc. against friends. up until now, i was an xbox user who used the xbox mic for voice chatting during games. i have a dedicated theater setup so i want all my sound coming from the 7.1 speakers. i only want to use a headset i already have (sennheiser pc 230 with built-in boom mic) to chat. i don't want any surround/game sounds to come out of the headset. so how do i do this exactly? i can go wired and i already have a usb to l/r audio converter from a corsair headset lying around if thats whats needed.
Not sure I follow exactly what you're looking for, but the easiest 'chat only' piece would be a bluetooth headset like what you use for a cellphone. Either the in-ear style, or I guess you can find a bigger type like the XBox communicator.
You have everything you need already (headset and USB converter). If you have game sounds coming out of the headset, you may have to adjust settings in your PS3.
