Love it so handy and amazing quality sound. . . . . .

Chromecast Audio has transformed my hi-fi system by giving me high quality music streaming and I wanted the same benefits in a portable speaker. I know there are Bluetooth speakers that provide better sound reproduction for the money, but the convenience of Chromecast Built-in sets this speaker apart. Bluetooth is very simple and convenient, but sound quality its limited by restricted bandwidth. Chromecast will give you the best quality feed available to it, so when using streaming services such as Google Play Music, the sound is CD-quality. Even challenging albums such as Eris Prydz's Opus sound fantastic The Music Center app is pretty easy to use and automatically selects the most appropriate connection (i.e. network or Bluetooth) according to what the app will allow.

This has a big sound from a small portable speaker
