Sonos Era 300 review: A big bet on spatial audio

If you pay attention to the music industry, you’ve probably heard about spatial audio. The promise is that music will envelop the user from all directions without needing a room full of speakers to achieve the effect. Apple has pushed it a lot in the last few years, in Apple Music, its line of AirPods headphones and the latest HomePod speaker. Amazon’s streaming service also offers spatial audio, and its Echo Studio speaker can play back compatible tracks.
