Would you pay $40 to make your headphones sound like simulated dts Surround? How about if the device to do it looked like a cool vacuum tube? $40 isn't a ton of money (at least not in this business) and IOGEAR is betting that consumers will want to spring for a new way to listen to 5.1 audio with headphones.

The idea is that you connect the USB device to a computer's USB 2.0 port, and you get a simulated surround sound experience on stereo headphones or even speakers. How does it do it? Well, we don't know the exact special sauce, but it's a combination of isolating and enhancing certain frequencies, varying the volume intensity and messing with time delay - pretty much all at the same time.\n\n\nDiscuss "IOGEAR USB Theater Sound Xperience (GUADT51) Preview" here.
