Cy-Fi - Mobile tunes for your bike

http://www.mycyfi.com/index.asp

I saw an ad for this in the latest Chicago Athlete magazine. The speaker weighs four ounces, mounts to your bike (or whatever) and connects wirelessly to your iPod or bluetooth device. Both options give you some remote control from the speaker. You can also sync to up to four other cy-fi speakers within range.

Not cheap at $130-150, I'm curious about the sound quality (claims to be 100% lossless, CD quality) and available volume output.
