I purchased the above dongle from ebay. It is a little usb dongle used to add a mic and headphone jack to just about any PC or Mac. The key thing is that it is driverless and so will be supported by the PS3. The main benefit is in playing a multiplayer game like Uncharted 2, that you have a clear headset and that it’s battery doesn’t run out. I used it with a really nice headset I got for a birthday a few years back. I don’t use the headphone jack, instead I use the headphone out on my 5.1 receiver.
