Pros: They work! And well too. I was able to hook them up to my Windows 7 PC and the drivers installed in seconds. But was disappointed to learn that Windows 7 won't allow 2 types of speaker outputs at the same time (it was either my Bose desktop speaker OR the Blue Auras, therefore I couldn't use them to expand upon my PC stereo set up, only replace.) So I ran the PC signal through my home stereo, and hooked up the transmitter to my stereo receiver, and it works fantastic.

Cons: Sucks that you can't expand on your current PC stereo with these, but I guess that's more of a Windows 7 issue. Could be different on MAC OS.

Overall Review: Know that you need to use the remote control to get the speakers to power on and work. My speakers are about 25-30 feet from the transmitter and on the other side of a wall.
