Levitating Bluetooth Orb Speaker
This isn't the droid you're looking for. But it is a speaker that sort of looks like the droid you might be looking for. Set the Levitating Bluetooth Orb Speaker on its magnetic platform and connect it to the right device and it will even light up, spin its head 'round and 'round, and beep-boop-boop-bee-boop for you.
I don't think these blue-and-white floating speakers--which also come in blue-and-black--were designed to look like R2-D2, but what a happy coincidence for Star Wars fans who also happen to like amplified jams and things that defy gravity that they do. The Bluetooth speaker system consists of the spherical floating Orb on top and a stationary support Base/charging dock underneath. It has 360-degree sound, with the portable Orb functioning both while "sitting" on the Base or sitting next to you on its own in the hammock. The base on its own can also charge your phone.
