When you want to make any moment fun, Party Ball USB is the way to go. This miniature dome flashes colorful red, green and blue lights on the walls and ceilings, creating an instant party in any setting.It’s powered by simply plugging it into any USB port—no messy AC cord and adapter required. Plug it into the back of your TV to set a compelling mood. Add it to your laptop and put an end to ordinary computer time forever. Connect it to your powered speaker (like ION’s Block Rocker) for a system with great sound and exciting visual effects. Party Ball USB has a built-in mic that synchronizes the lights to sounds in the room and its bendable gooseneck arm means you can position it exactly where you want it.
