Our Take
The Sonos Era 300 is a premium wireless smart speaker designed specifically around spatial and Dolby Atmos audio. It's aimed at music enthusiasts who want a genuinely immersive listening experience without a full surround-sound setup. Sitting at the higher end of the standalone smart speaker market, it competes with high-end single-unit speakers rather than budget streaming options.
Key Features
Six-driver array (four tweeters, two woofers) arranged to project sound upward and outward for spatial effect
Dolby Atmos decoding built in, playing Atmos-mixed tracks from compatible streaming services including Apple Music and Amazon Music
Wi-Fi and Bluetooth 5.0 connectivity, with Bluetooth usable without a network connection
Line-in via USB-C adaptor, allowing wired sources (adaptor sold separately)
Amazon Alexa voice assistant built in; works within the Sonos ecosystem with other Sonos speakers
Pairs as a stereo pair or as rear surrounds with a Sonos Arc soundbar
Our Verdict
The Era 300 is worth serious consideration for anyone already invested in the Sonos ecosystem or committed to spatial audio. If you subscribe to Apple Music or Amazon Music and want room-filling sound without separates, it delivers. Budget-conscious buyers or those outside the Sonos ecosystem will find it harder to justify the outlay.
