Upon first glance, these In2uit Filo portable Bluetooth speakers might seem more style than substance. Nope. The svelte profile is a direct result of function. The Filo uses electrostatic speakers instead of fat, magnetic drivers.

The wee boombox is only 2.5 inches thick and just 1.5 pounds. Uncannily thin. Combine that with a 10-hour battery life, and you're ready to hit the backyard BBQ circuit. As far as sound quality goes, electrostatic speaker technology is more commonly found in more high-end applications so there's a good chance that this super model can sing too. (CNet said that the audio quality "seemed fine") The Filo hits store shelves next month for $250. [In2uit via CNet]
