World’s first levitating Bluetooth speaker? That’s what the OM/ONE hopes to be with a little help from some crowdfunding. The baseball-size wireless speaker from Om Audio LLC magnetically floats an inch above its base. The 1.3-pound orb ($179 for early backers) has a 75mm driver, a microphone, a 15-hour battery and can be used as a speakerphone. The OM/ONE can also be used as a portable speaker without the base and two units can be paired into a stereo speaker system.
