No more running cables or tripping over speaker wires. Logitech unveiled the world´s first THX-certified 5.1 speaker system with digital wireless dual rear speakers.

Oregon Scientific has announced the iBall, a wireless speaker that's the size and shape of a bowling ball (think ten-pin bowling, not pensioners on manicured lawns). Plug your iPod into the transmitter dock, which also acts as a charging station, and your music flows wirelessly to the iBall, which can be up to 30m away. You can leave your iPod in the living room and listen to your tunes to the kitchen, the bedroom or even the garden, without the hassle of stringing cables around the house.

Logitech today introduced the Logitech® Wireless Music System for iPod®, which allows people, in a matter of minutes, to wirelessly connect their iPod or MP3 player to a stereo or speaker system, share their digital music out loud, and control the music using their player as a remote control.

Recent studies on consumer behavior unveiled that people using a home theater system rarely install the rear speakers, because of the hassle of laying those long wires.
