I have an older headset from the PC version of Battlefield 2, but it has those mini-RCA type jacks that go into the older soundcards.

Is there an adaptor of some sort that would be a USB cable on one side and that mini-RCA connection on the other?

I am trying not to buy a new USB headset if I don't have to. Thanks

If there was some sort of adapter like that, it would probably cost as much as a new USB headset.
