Sonos Era 300 Review: Sound, Reimagined

For years, the smart speaker race has been about getting louder, smarter, and smaller. With the Era 300, Sonos is changing the direction of the race entirely—sideways, upwards, and all around. This isn’t just another speaker; it’s a statement of intent and a vessel for the next wave of audio consumption: spatial audio. Billed as a ground-up redesign to master Dolby Atmos Music, the Era 300 aims to place you in the center of your favorite tracks, not just in front of them. But in a world where content is king, can this futuristic speaker deliver on its promise today? Let’s dive in.
Performance: The Spatial Audio Revolution
The entire reason for the Era 300’s existence is spatial audio, and when you feed it a proper Dolby Atmos track from a supported service like Apple Music or Amazon Music, the results are nothing short of breathtaking. The speaker’s complex array of six drivers—including an upward-firing tweeter to bounce sound off your ceiling and side-firing tweeters for width—works in harmony to create a truly immersive, room-filling soundscape. Instead of a simple left-right stereo image, music is deconstructed and projected around you. Vocals hang in the center of the room, instruments seem to emanate from distinct points in space, and ambient effects wash over you. It’s an experience that a traditional stereo speaker simply cannot replicate.

Of course, the vast majority of music is still in stereo. Here, the Era 300 performs admirably, but with a different character. It processes stereo tracks to create an impressively wide and expansive soundstage. However, this focus on dispersion means it can lack the sharp, direct focus of a more traditional bookshelf speaker. It’s a trade-off: you sacrifice a bit of pinpoint imaging on standard tracks for the magical immersion of spatial audio. For home theater enthusiasts, two Era 300s used as rear surrounds with a Sonos Arc soundbar is a game-changing upgrade, delivering the most convincing and enveloping Atmos movie experience Sonos has ever offered.

Design and Connectivity: A New Era for Sonos
The Era 300’s design is as unique as its sound profile. Its cinched, hourglass-like shape is dictated by the precise angles required for its drivers. It’s a bold look that won’t blend in as seamlessly as a Sonos One, but its matte finish and excellent build quality feel decidedly premium. Sonos has also continued its commitment to sustainability, constructing the speaker from post-consumer recycled plastics. On top, a new indented volume slider offers more intuitive tactile control than the previous generation’s tap-to-adjust buttons.
More significantly, the Era 300 finally addresses long-standing criticisms of the Sonos ecosystem. It not only features Wi-Fi 6 for robust streaming but also adds Bluetooth 5.0, allowing for quick, direct playback from any device without needing the Sonos app. Around the back, a USB-C port provides a line-in option for connecting external sources like a turntable—a huge win for versatility. The only caveat is that this requires a separate, proprietary adapter from Sonos, which feels like an unnecessary extra purchase.

Features and Value
Beyond the hardware, the Sonos software experience remains a key selling point. The app is polished, and setup is a breeze. Trueplay, Sonos’s acoustic room-tuning technology, is now available in two tiers. iOS users can still use the advanced tuning method that uses the phone’s microphone to map the room, while a new “Quick Tune” option uses the speaker’s own microphones, finally bringing a version of the feature to Android users. Voice control is also flexible, with support for Amazon Alexa and Sonos’s own privacy-focused Sonos Voice Control.
At its price point, the Era 300 is a significant investment. It’s more expensive than competitors like the Apple HomePod, which also offers compelling spatial audio. However, the Era 300’s value proposition is tied to its flexibility. It’s a fantastic standalone spatial audio speaker, a capable stereo smart speaker, and a phenomenal home theater surround speaker all in one. The addition of Bluetooth and line-in capabilities makes it the most open and versatile speaker Sonos has ever produced.
The Verdict
The Sonos Era 300 is a forward-thinking and exceptionally engineered speaker. It’s an audacious bet on the future of music, and when conditions are right, it delivers an experience that is genuinely new and exciting. While its performance with standard stereo can feel slightly less direct than its predecessors, its spatial audio prowess is undeniable.
This speaker is for the audio enthusiast who is excited about the potential of Dolby Atmos Music and wants the best-in-class hardware to experience it. It’s also the definitive upgrade for Sonos users looking to build the ultimate Atmos home theater. If you’re invested in the future of sound and value platform flexibility, the Era 300 is not just a great speaker—it’s a glimpse of what’s to come.
