Our Take
The Sonos Era 300 is a premium wireless speaker designed specifically for spatial audio, capable of decoding Dolby Atmos music. Aimed at serious listeners who want immersive, room-filling sound without a full home cinema setup, it sits at the top of Sonos's standalone speaker range and pairs with a second unit for true surround use.
Key Features
Supports Dolby Atmos music playback via Apple Music, Amazon Music, and Tidal
Six-driver array including upward-firing and side-firing tweeters for spatial audio projection
Bluetooth 5.0 connectivity added alongside Wi-Fi streaming
Compatible with Sonos app, Apple AirPlay 2, and voice assistants (Amazon Alexa, with support for others)
Can be used as a rear surround speaker paired with a Sonos Arc soundbar
Trident-shaped acoustic design with a dedicated upward-angling channel to bounce sound off the ceiling
Our Verdict
The Era 300 is best suited to committed Sonos users who stream from Atmos-enabled services and want genuinely immersive music listening. Those new to Sonos, working with a tighter budget, or unconvinced by spatial audio for music should consider the more straightforward and affordable Era 100 instead.
