If regular portable speakers don’t appeal, try the Lyrix Axis. It levitates, charges wirelessly, and pumps out great sound. You can currently grab one for $140 shipped via 9to5Toys Specials.
The speaker part of the Lyrix is the floating orb, which is kept hovering by the electromagnetic base. The base also provides wireless power, although the orb has a rechargeable battery, meaning it can be used independently for hours of playback. Along with impressive Bluetooth audio quality, the orb has physical controls and an LED belt that provides a colorful display. The lack of sound distortion is particularly noticeable; because the orb is levitating, it does not make other surfaces vibrate. When the base isn’t being used to charge the speaker, it can also charge other USB devices via the in-built port.
If you are trying to find a gift for the person who has everything, this is definitely a good option. The current deal takes 30% off the regular price, and shipping is free to the Continental US.
