Audioengine describes their product in one sentence perfectly: "Transfer music wirelessly from any audio device or computer to your Audioengine powered speakers, surround receiver, or powered subwoofer."

It's crazy simple, plug one gum sized device into the source, be it iPod, computer, CD player, or what have you, and the other one into a power socket, and a receiver or powered speakers. Presto, you have a wireless connection and uncompressed (or no additionally compression anyway) audio up to 100 feet away.

If all your music is on your computer in your den, this would let you play it back on your home theater system, without extensive networking options or running lots of wires. Simple, cheap, and a handy gadget. Sign me up.
