Product Description:
Turtle Beach Audio Advantage Micro - This USB home theater audio device gives you a realistic 5.1 surround sound experience on a standard set of headphones! You don't even need surround sound audio to begin with either. Even stereo music gets the surround sound treatment with the Audio Advantage. There's even a built-in S/PDIF output for pass-through of Dolby Digital & DTS sound to digital speaker systems or home theater A/V receivers. Audio Control Center software included

Rating : - Use caution the first time.
The good news is that the tiny USB Turtle Beach Voyetra Sound card and its software work fine with my laptop running Windows Vista Home Premium. The bad news is that I was hoping it would also work on my Mac Mini running OS X and on my portable running Linux but it doesn't. It does what it says it will do but I was hoping for more. The manufacturer never promised that they had hired a Linux or Mac programmer but I was hoping they had.

Caution: Do NOT use headphones the first time you plug it in. I seldom read instructions until after a disaster and this little sound card was set at maximum volume at the factory. Fortunately I had it plugged in to a stereo system and not directly to my ears. I only rattled a few windows.
