The Coby CSP95 allows you to listen to music, movies, and more in places where running wires was too much of a hassle.  Just plug the base transmitter into any 3.5mm stereo out plug, get the wireless speakers powered with either the included AC plugs or 8 C batteries each (yes, 8 each, these aren't weak speakers), set them on the right channels and go!  Each speaker has it's own volume channel, and on off controls.  Great for use in the kitchen, deck, patio, greenhouse, garden, garage, etc.
