Through its 360 by Deezer app, the streaming service is adopting Sony's 360 Reality audio format, supporting the company's 360-enabled SRS-RA5000 and RA3000 models. These Chromecast-enabled speakers are getting a new casting feature that offers that immersive audio. You'll need to subscribe to Deezer's premium HiFi tier and use the app to get this feature working.
Once you do, pick a track on the 360 by Deezer app, then select the "cast" button on the top right corner. This format will allow you to hear different parts of the song as separate, independent sound "objects" with vocals and instruments "placed in positions in a virtual auditorium to create a truly immersive experience for the listener." Deezer joins the likes of Amazon Music and Tidal to get support for Sony's surround sound tech.
