Terratec’s Headset Master 5.1 USB headphones claims to offer true surround sound, something which is pretty difficult to pull off considering the fact that all the speakers are located so close to one another. Most of the time, such headphones are great for gaming purposes, but when movies are involved, what you get is basically stereo sound. This USB-powered headset does away with the need for any external power adapter or sound card which is always a good thing.
