Remember the Om/One levitating speaker? It now has a UFO-shaped competitor fittingly called the Mars levitating speaker. Mars is promised to provide 360-degree sound projection due to its shape and levitating nature. A subwoofer charging station is positioned below the floating speaker -- called the "craft" -- and is complemented by an integrated microphone for taking calls. Perhaps with a hint of humor, the maker notes its Mars speaker is made with aircraft-grade aluminum.
