Check out the levitating Bluetooth speakers in the photos on this page (via Engadget). They were made by ASWY, and are called Floating Bluetooth Speakers. Currently there isn’t much info about the levitating Bluetooth speakers on the ASWY website. But according to Engadget, the speakers feature three watts of output, five hours of battery life, Bluetooth 4.0 support, 3.5mm input jack, integrated microphone, and a USB port. The speaker includes a powered base to keep it in the air, but the speaker will still work without the base if you don’t need it to levitate.
