Can any pair of USB Headsets work on ps2, or only the ps2 USB Headset?

May be...

Cause i bought a usb headset, but its not the ps2 one. And it doesn't seem to work..... If it helps, its not for online gaming, its just for Nascar 06 Voice Command?

unfortunatlyit has to be ps2 but if you will use it alot try the ps3 bluetooth

No it doesnt work you have to use the ps2 headset
