You can have instant access to your entire digital music collection, including all your playlists, from anywhere in your home: inside or out. That's because the Sonos Controller uses Sonosnet, our secure wireless mesh network that extends the range of your Controller throughout your entire home. Which means you don't have to run to your PC every time you want to turn on, change or turn off your music. And, you can control everything from volume to music selection in any room from anywhere.
