Small enough to fit in the palm of your hand, yet powerful enough to fill a room with music via Bluetooth technology. The Mini Bluetooth Speaker provides a convenient way to wirelessly amplify your digital music. Using Bluetooth technology, it connects to your device within a range of about 30 feet. It even lets you answer phone calls through the speaker! The aluminum body design is sleek and inconspicuous, as well as sturdy and durable. An internal lithium battery can be recharged to keep the speaker running without wasting money on disposable batteries. What's more, a built-in MicroSD card reader lets you play a library of music without the need for a Bluetooth device. The included u-mount bracket mounts to round tubing up to 3/4", ideal for microphone stands or boom arms.
