Wireless Bluetooth speaker with FM radio and MicroSD card slot<br>The Sound Science Metallic LED Bluetooth Speaker is a highly versatile little wireless speaker that can follow the party no matter where it goes. Bluetooth technology allows it to connect to smartphones, tablets, laptop computers and other devices from up to 10m away. 52 mm neodymium drivers pump out rumbling bass and high-quality sound. Its compact size fits easily into a bag or backpack. Whats even better is that it doesnt need to be connected via Bluetooth for you to enjoy your music. Plug a Micro-SD memory card into the back and use the built-in MP3 player to rock out. Or, you can connect a 3.5 mm stereo cable (included) to your audio device, then plug the other end into the audio jack on the back of the speaker for wired audio playback. If those cool features werent enough, you can listen to the radio without an internet connection with the FM mode.
