Mars by Crazybaby without a doubt is one of the coolest wireless speakers we have seen. The Mars is a levitating satellite speaker that hovers, via magnets, just above its subwoofer base. It also sound pretty good, for its small size.
When levitating over the base it takes on the appearance of a UFO flying saucer. That will definitely impress your friends.
The saucer-shaped design provides for 360-degree sound, so that you can centrally position the device in a room and everyone can hear it. The subwoofer base, which contains a large battery, has USB ports you can use to plug in your smartphones and tablets for on-the-go charging.
The Mars is made of aircraft aluminum with solid build quality. It is portable, with eight hours of playback time per full charge. It can also be used as a wireless speakerphone, and is waterproof at up to 3 feet submerged. Available in 3 colors, silver, black and white.
At its price point, there are better sounding wireless speakers available, but nothing that comes close to its gadgetry cool factor.
