If you've found the official PlayStation 3 Bluetooth headset
a little too monaural
(or small) for your liking, listen to this. Sony will be releasing the PS3 Wireless Stereo Headset this September, offering one more audio channel and a much larger, over-the-ear form factor for a cool $100.
It's not actually a Bluetooth device -- the headset comes with a USB dongle needed to make it work, so getting that USB hub you've been thinking about would be a good idea if you want these cans. In addition to delivering "virtual" 7.1 surround sound and a fold-away boom mic, the rather hefty-looking accessory appears to include a PS2 Slim console over either ear. Weird, right?
