Sonos Era 300 Speaker
The Sonos Era 300 is a premium wireless speaker designed around spatial audio playback, including Dolby Atmos Music, sitting at the upper end of Sonos's home speaker lineup.
### Overview
The Era 300 is Sonos' first upward-firing Dolby Atmos smart speaker, designed to bring a genuinely immersive listening experience to a single room without a full surround sound setup. Its focal point is spatial audio playback, achieved through a carefully considered but unusual arrangement of drivers and amplification that fires sound in all directions. Priced at $379, it sits at the premium end of the smart speaker market and is best appreciated by listeners who stream Dolby Atmos Music content.

### Standout Features
- **Dolby Atmos spatial audio:** Six drivers — four tweeters and two woofers — are complemented by custom waveguides that help direct sound forwards, upwards, left, and right to surround you with music. - **Six dedicated amplifiers:** Each of the six drivers is powered by its own Class D amplifier, ensuring precise, independent control over every channel. - **Trueplay room calibration:** Trueplay measures the room's acoustics to maximize audio quality, guided by the Sonos app, which has you wave your phone around the room for a few minutes to calibrate the speaker. - **Wi-Fi 6 and Bluetooth:** The Era 300 supports both Wi-Fi 6 and Bluetooth — the first time Bluetooth has been included in Sonos's mains-powered speakers. - **Multiple voice assistants:** You can set it up with Amazon Alexa or Siri, and it also has Sonos Voice Control, which can perform specific functions like grouping and ungrouping Sonos devices. - **Versatile as surrounds:** When paired with a Sonos Arc or Beam Gen 2 soundbar, two Era 300s can deliver multichannel surround sound.

### Who It's For
This speaker is ideal for music lovers who subscribe to services offering Dolby Atmos Music tracks — such as Apple Music or Amazon Music Unlimited — and want a meaningful spatial audio upgrade without wiring a full surround system. It works well as a standalone room speaker or as a stereo pair in the same room for a 3D soundstage. It's also a strong choice for existing Sonos households looking to add immersive rear channels to a soundbar setup.

### Important Considerations
- **Spatial audio content dependency:** The immersive effect is most pronounced with Dolby Atmos Music tracks; it's also a capable speaker for non-spatial audio tracks — crisp, clear, and capable of getting very loud — but the premium price is harder to justify if you don't regularly stream Atmos content. - **Apple ecosystem note:** HomeKit is supported for music control, but there are some reported issues with Apple AirPlay functionality worth being aware of, particularly with certain streaming apps. - **Occasional software quirks:** Some users report connection glitches when directly connecting to Spotify, where the app doesn't always track playback — a minor but notable flaw. - **Not portable:** Unlike the Sonos Roam or Move, the Era 300 is a mains-powered home speaker with no battery, so placement is tied to a power outlet.

The Era 300 is built for the spatial audio era — if your library supports it, the difference is audible.
What stands out
- Designed specifically for Dolby Atmos Music, with drivers angled to project sound upward and to the sides for a genuinely immersive effect
- Apple HomeKit support allows voice and app-based control within an Apple smart home setup
- Integrates into the broader Sonos multi-room ecosystem, keeping it compatible with a wide range of existing Sonos hardware
- Supports a wide range of streaming services and can be paired as a stereo pair for home theatre use
What to weigh
- Spatial audio content is still relatively limited across streaming catalogues, so the headline feature won't always be in play
- Premium pricing places it above most competing single-room wireless speakers
- Dolby Atmos Music benefits are most apparent in a treated or well-proportioned room — open-plan or acoustically busy spaces may reduce the effect
Great fit if
- Listeners who stream Dolby Atmos Music on services like Apple Music and want to hear it as intended
- Existing Sonos households looking to add a high-performance room speaker
- Apple HomeKit users who want a speaker that integrates cleanly with their smart home setup
Skip it if
- Shoppers whose streaming service doesn't offer spatial audio content, as the core differentiator won't apply
- Those seeking a budget-conscious wireless speaker — the Era 300 is a premium outlay
- Listeners in very small rooms where wide sound dispersion may feel excessive
