Audioengine B1 Bluetooth Audio order Receiver

Product Name: Audioengine B1 Bluetooth Audio order Receiver
Bought new 6 months ago for $100. It's been used for much of that time, but it still looks and works like new. Comes with everything from the original package, including RCA cable, power adapter and cable, manual, product catalog, and strangely enough, microfiber carrying pouch (??) I'm also throwing in the optical order cable that I used with it. (If you're using it with a nice stereo, the optical connection sounds very noticeably better.) Like most Bluetooth devices, it only maintains one connection at a time, and switching is often a manual process, which can be annoying. Otherwise, it works and sounds great.
