Sonos Controller CR100 

The Sonos Controller gives you instant, wireless access to all your music and all your rooms. SonosNet ensures that every Controller works wirelessly, all over the house, so you don’t have to run back and forth to your computer. Instead, you can choose exactly what to play and where to play it from anywhere — sitting on the couch or cooking in the kitchen. With the Controller in hand you can find and play music from your personal music collection, Internet radio and the most popular online music services. And using the Controller couldn’t be easier. Just pick a room, pick a song and hit play. Use search to find your favorites, and quickly link and unlink zones to play the same song in every room or different songs in different rooms. Controllers aren’t tied to a specific ZonePlayer, so you can use any Controller to control the music — and the volume — in any or all rooms. And there’s practically no limit to how many Controllers you can have — one for every room, floor or music lover in your house.
