Of course, there's no timetable for that. It's assumed that when it eventually rolls out its lossless streaming service, Spotify HiFi, that it'll also roll out support for Dolby Atmos, too. Spotify doesn't support Dolby Atmos or spatial audio right now. (Previously, Amazon Music Unlimited was the only major music streaming service to support an entire catalog of Dolby Atmos content.) This means that Apple Music subscribers will be able to get the most of the Era 300 and its new immersive sound. Along with the announcement of the Sonos Era 300, it was announced that Apple Music is going to roll out support for Dolby Atmos on March 28th. Neither Spotify or Apple Music support Dolby Atmos - but that's about to change. We'll likely have to wait for Spotify to roll out support for Dolby Atmos and spatial audio (more on this below), which it could package with Spotify HiFi and then justify a higher-priced tier. Apparently, there's no longer the financial incentive to launch it right now.

According to the latest reports by The Verge, Spotify HiFi has been ready to launch for over a year, but Apple's decision to roll out lossless audio has caused Spotify to stall. Spotify claims to be launching its own lossless streaming service, Spotify HiFi, but it's not here yet even though Spotify originally claimed it would launch by the end of 2021 - that means it's almost a year-and-a-half late. The kicker: to listen to these lossless tracks, subscribers just have to pay the same $10/month charge as before. In May 2021, it added a lossless tier that allows any paying subscriber to listen to CD-quality (16-bit/44.1 kHz) and Hi-Res Lossless (up to 24-bit/192 kHz) audio tracks.

The biggest difference between the two streaming services is Apple Music actually allows you to listen to lossless tracks.
