A:
sadly yes BUT!!!!! the G230's are the same one, they don't include the usb sound card adapter. So if you have a sound card that supports 5.1 or 7.1 emulation ( Razer surround, Dolby headphone, CMS 3D creative SB )
they will perform the same function and quality.
if you use onboard audio, you can team the G230's with razer surround software to get 7.1, and the basic 7.1 mode is free.
