Plug this Star Wars R2-D2 Bluetooth Speakerphone into a USB port, and itll charge up. When its charged, either pair the speaker with your Bluetooth-enabled phone or plug your audio device into Artoos standard 3.5mm audio jack. Artoo will light up, literally, including the familiar indicator light and some new funky blue "underdome" lighting hes had installed. Since hes Bluetooth, you can even make calls on him when you have your phone paired up. But his raison detre is to play music for you.
