Chromecast Audio is a small device for streaming music through Wi-Fi. It connects to virtually any stereo system, bookshelf speaker, table-top radio, or desktop speaker, allowing users to listen to their favourite music via smartphone, laptop or PC on any speaker in the house. The round, puck-shaped design with delicate grooves, reminiscent of vinyl, provides easy handling. It comes with a 3.5 mm auxiliary cable that lies flat around the device and headphones.
