Chromecast Audio is a small streaming device that simply plugs into the AUX input of your speaker. This makes your speakers Wi-Fi capable. After setup, you can easily stream your favorite music to the speakers using your iPhone, iPad, Android smartphone or tablet, Mac or Windows laptop, or Chromebook.

Just tap the Cast icon in your music app to stream to your speakers. You can then control the speakers from anywhere in your home with your smartphone, allowing you to find, play, pause your favorite songs, or create a playlist. Of course, you can also adjust the volume directly from your smartphone.
