Wireless metallic LED Bluetooth speaker - Have a blast this summer. The Manhattan metallic LED Bluetooth speaker 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 10 m (30 feet) away. Its compact size fits easily into a bag or backpack. Bluetooth is not a must for you to enjoy your music – plug a Micro-SD memory card or USB flash drive into the back and use the built-in MP3 player to rock out. Or, connect a 3.5mm stereo cable (not included) to the headphone jack of 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 weren’t enough, the speaker has an internal microphone for making and taking calls, a rechargeable battery that will last for up to 5 hours when connected wirelessly, and Bluetooth media controls that will let you pause, play, and switch tracks on your connected device.
