Google Chromecast Audio: Stream your favorite music with Google Chromecast Audio. Simply plug into your speaker's auxiliary input and connect to your Wi-Fi network. Then just tap the Cast button from your favorite apps on your phone, tablet or computer to cast songs, radio stations and podcasts to your speaker.
This is my second Google Chromecast Audio. Both work like a charm with my Plex media server and deliver music where and when I want it. Best value in wifi audio.
