There are hundreds of Bluetooth enabled speakers on the market these days. They can be small enough to fit in your pocket, loud enough to compete with an in-house sound system, or versatile enough to take with you into the shower. To stand out in the market, developers really have to start getting creative with their products.
The OM/ONE is just such a speaker. Not only does it let you play music from your iOS device more than 30 feet away, but it levitates like the orb in Phantasm, only not so deadly.
