This is the gravity defying wireless speaker that floats in mid-air above its base, and it is only available from Hammacher Schlemmer. A magnet inside the spellbinding sphere is repelled by electromagnetic coils in the base, a powerful opposing force that causes the speaker to levitate. More than a mere novelty, the speaker delivers impressively robust audio from its full-range 2-watt driver when paired with a Bluetooth-enabled device up to 30' away. Volume is controlled from your device and red or blue lighted rings on the base and speaker add a mystical glow. Less awe-inspiring than levitating but extraordinary nonetheless, the speaker also magnetically grips to horizontal metal surfaces such as a shelf or refrigerator. Its Li-ion battery provides up to five hours of playing time on a three-hour charge via USB (cable included). Blue. Base plugs into AC. Speaker: 3 3/4" H x 3 3/4" W x 3 3/4" D. Base: 1" H x 5 3/4" diam. (1 1/2 lbs.)
