We have covered plenty of fancy speakers here in the past. Mars by crazybaby is quite special though. It is a levitating Bluetooth speaker with a UFO shaped craft that floats above the base. It provides you with 360-degree sound experience. The craft lands slowly on the base when it runs out of battery. It charges wirelessly.
The Mars Craft is portable and waterproof to 3 feet deep. It is magnetic, so you can attach it to your bike. The speaker connects to your smartphone via Bluetooth from 33 feet away.
