Belkin today added a Bluetooth Music Receiver to its lineup for short-range wireless streaming. The adapter takes audio from any Bluetooth device that supports the A2DP stereo format, including many cellphones (such as the iPhone) as well as portable media players that recognize the standard, such as the second- and third-generation iPod touch. Range is limited to the Bluetooth standard's 33 feet but should be enough for wireless music in the same room.
