Belkin Bluetooth Music Receiver
You shouldn't have to buy an all-new setup just to wirelessly stream music from your phone or music player to your existing audio equipment, and with the Belkin Bluetooth Music Receiver ($50), you don't have to. This small black dongle includes 3.5mm to RCA and 3.5mm to 3.5mm cables to connect to nearly any piece of audio equipment, and uses Bluetooth 2.0 EDR and A2DP to deliver quality sound from up to 33 feet away.
