Sonos Era 300 Review: Spatial Audio Excellence with Dolby Atmos

The Sonos Era 300 represents a bold leap into the future of home audio. With its unconventional design and Dolby Atmos support, this speaker promises to transform how you experience music by surrounding you with sound from every direction. After extensive testing, I can confirm it largely delivers on that ambitious promise.

This isn't just another smart speaker—it's an audio experience that needs to be heard to be believed.

Design: Form Follows Function

The Era 300's distinctive hourglass shape isn't just for aesthetics—every curve serves the acoustic engineering. The sculpted form houses six precisely positioned drivers: front-facing, side-firing, and upward-firing speakers that work together to create a three-dimensional soundstage.

Available in Black and White, the speaker has a premium feel with its soft-touch finish and minimalist control surface. It's larger than you might expect from photos, but the footprint is reasonable for desk or shelf placement.

Sound Quality: The Main Event

This is where the Era 300 truly shines. The spatial audio experience is nothing short of remarkable. When playing Dolby Atmos tracks, the sound doesn't just come at you—it surrounds you. Custom waveguides disperse audio right, left, forward, and above, creating a sensationally spacious soundstage that fills the entire room.

The bass response is powerful without being overwhelming—one tester noted it "booms through walls." The six drivers deliver crystal-clear mids and highs while maintaining that room-filling low end. Whether you're listening to orchestral pieces, hip-hop, or podcasts, the Era 300 handles everything with finesse.

Even with standard stereo content, the Era 300 creates impressive separation and depth. The listening experience is extraordinary regardless of where you're positioned in the room.

Home Theater Integration

Pair two Era 300 speakers with a Sonos Arc or Beam (Gen 2) soundbar, and you've got a seriously impressive home theater setup. The lateral and overhead channels in each speaker create an all-encompassing soundstage that rivals dedicated surround sound systems.

Supercharged by Dolby Atmos, movie watching becomes genuinely immersive. Raindrops fall from above, helicopters pan across the room, and dialogue stays anchored to the screen. It's the kind of audio experience that makes you want to rewatch your favorite films.

Connectivity and Smart Features

The Era 300 offers versatile connectivity options. Stream from all your favorite services over WiFi for the highest quality audio. Need quick pairing? Bluetooth is available with a single button press. You can even connect a turntable or other audio source using the Sonos Line-In Adapter (sold separately).

Sonos Voice Control provides hands-free operation with a focus on privacy—your voice commands are processed on-device rather than sent to the cloud. Amazon Alexa integration is also built-in for those who prefer it. Sonos Radio gives you free access to curated stations and original content.

The App Experience

This is where the Era 300 experience stumbles. The Sonos app has been widely criticized by users, and those complaints are valid. The interface can be unintuitive, and some users describe it as frustrating to navigate. While setup is generally straightforward, day-to-day app usage could be smoother.

Sonos does push regular software updates that add new features and improvements, so there's hope the app experience will improve over time. For now, it's a genuine weak point in an otherwise excellent product.

Value Proposition

At its premium price point, the Era 300 isn't for everyone. Casual listeners may find it hard to justify the cost compared to more affordable smart speakers. However, for audio enthusiasts and home theater builders, the spatial audio capabilities and build quality make it a worthwhile investment.

Those who appreciate the difference Dolby Atmos makes will find the Era 300 delivers genuine value. It's the kind of speaker that reveals new details in music you've heard hundreds of times.

Final Verdict

The Sonos Era 300 is a remarkable achievement in speaker design. Its spatial audio capabilities are genuinely impressive, creating an immersive listening experience that few competitors can match. The six-driver system delivers exceptional sound from wall to wall and floor to ceiling.

The app frustrations are real, and the premium price will give some buyers pause. But for those who prioritize audio quality and want to experience music in a new dimension, the Era 300 delivers. Pair two with a Sonos soundbar, and you have a home theater setup that punches well above its weight.
