This is the Bluetooth stereo speaker that is only slightly larger than a casino die. It’s small enough to attach to a keychain with the included lanyard and stores unobtrusively in a pocket yet produces surprisingly crisp, clear sound. Connecting to an iOS or Android device from up to 30' away, it enables one to stream music or a podcast without having to wear earbuds or be tethered to an outlet. With a magnetic backing for adhering to a toolbox or refrigerator and included micro-USB charging cable. A 45-minute charge provides three hours of power. Includes two 1 1/4" cu. speakers for stereo sound.
