Overinflate these Cebop Pop speakers and you give new meaning to the term "pop music." The idea here is that when deflated they're nice and small, fitting into your bag so you can take them on the road, but when you inflate them to their full 8.5-inch height, theoretically you'll get the bigger sound of larger-sized speakers.
The speakers work differently from garden-variety boom boxes, using what the company calls an "NXT Exciter" to rock sound waves across the entire plastic skin, spewing sound in all directions. They're cheap, at $49.50, and they look cheap, too. Sounds like a lot of hooey.
