Versatile wireless features from a super-compact speaker
Looking for a great-sounding speaker for your nightstand or bookshelf? The compact Yamaha MusicCast 20 gives you lots of ways to listen.

And the MusicCast 20 can connect to your home Wi-Fi network to give you access to internet radio, podcasts, and more.
Clear sound and intuitive controls

MusicCast: simple multi-room audio
You can combine up to 10 MusicCast speakers and components in a whole-house system, and control them all with Yamaha's excellent MusicCast mobile app. Play your digital music library, internet radio stations, and popular streaming services. There's support for Pandora® and SiriusXM. If you're a Spotify® Premium subscriber, Spotify Connect lets you access all your favorite albums and playlists.

Wireless surround sound? Yes, please.
