Sony says their new DR-GA500 headphones have "7.1 channel digital surround sound for first person shooters." I really don't care much about first person shooters, but I can't resist their fantastic design, straight from the set of Tron Legacy.
The headphones have an external audio processor that supports Dolby Pro Logic IIx and simulates sound immersion in game environments with only two 40mm drivers. It also comes with a boom mic to chat. For now, it's Europe only, sadly. [Sony]
