As for unsightly wires, the Audyssey Wireless Speakers have two: the unavoidable power cord (with a chunky power supply) as well as a thin black-and-red cable that connects the left and right channels. (You may want to replace this with more discreet, clear speaker wire if you can't hide it somehow.) Both make the speakers better suited to a permanent set-up than on-the-go listening.
