MixAmp 5.8 turns any wired headset into a wireless surround sound system

Being wired for sound to a games console can be a somewhat restricting experience, especially if you're trying to release your inner rock star with games like Rock Band 3. Astro Gaming has taken its pro-gaming MixAmp audio technology and made it both wireless and home-friendly. Users of the MixAmp 5.8 system can plug in just about any pair of wired headphones to the wireless receiver and benefit from 7.1-channel Dolby Surround Sound and a virtually interference-free wireless connection to the transmitter.

The MixAmp 5.8 has a recommended usable range of 100 feet (30.5 meters), although the system can transmit its wireless signal for quite a bit more.
The transmitter also has a couple of USB ports thrown into the mix, for which Astro plans to develop accessories, and that can currently be used as a power source for the receiver unit when the included batteries run out of juice.
The MixAmp 5.8 system is available now for a special introductory price of US$99.95, with various options also on offer. The product is shipped with a set of AAA-sized batteries and belt clip for the receiver, an AC adapter for the transmitter, an optical audio cable, Xbox Live Chat cable and a USB play/charge cable.
It's worth repeating that the only audio input available on the MixAmp 5.8 is a TOSLink Optical port, so if your games console doesn't have optical input, then this is not the solution for you.
