Klipsch announced their new ProMedia 2.1 speakers today. Designed for use with a laptop system in mind, these THX-certified speakers are
totally mostly wireless.
So by mostly wireless, I mean that you still need to provide power. The subwoofer and speakers will need to be plugged in to work, just not into your computer. You will need to stick a dongle into your USB port however. This sounds ideal for a laptop user or college student, since you can bring your computer back to the speakers and not have to worry about the cables.
The Klipsch ProMedia 2.1 wireless speakers sell for $199, and are only available from the Klipsch website, and only in the U.S.
