Sonos Era 300
The Era 300 turns a single wireless speaker into a room-filling spatial audio experience, casting detailed vocals, taut bass and convincing Dolby Atmos height well beyond its compact cabinet. What Hi-Fi? applauds its immense scale and cohesive dynamics, while Trueplay adds welcome focus and balance. Bluetooth, AirPlay 2 and Sonos multi-room polish complete an exceptionally immersive smart-speaker package.

Pros
Exceptionally expansive, immersive Dolby Atmos presentation with convincing height and sound extending far beyond the cabinet.
Detailed, cohesive sound combines clear vocals, fluid dynamics and punchy, deep bass.
Trueplay room tuning substantially improves focus, vocal clarity and bass balance.
Strong streaming and smart-home versatility, including Wi-Fi, Bluetooth, AirPlay 2 and responsive app controls.
Cons
Premium price is high for a single speaker, and expanding to stereo or surround raises the investment substantially.
Default tuning can be bass-heavy and obscure vocals until Trueplay or EQ adjustments are applied.
Wired line-in requires a separately purchased adapter, and Tidal Dolby Atmos is unsupported.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 90/100
The Era 300 is widely praised for unusually expansive, room-filling sound from a compact all-in-one speaker, particularly with Dolby Atmos material. Trueplay is repeatedly recommended: it improves focus and vocal clarity while reducing the default bass heaviness, and the strongest results come from well-recorded or spatial-audio content.
Bass
88/100
Reviewers hear deep, punchy and rhythmically capable bass for a speaker of this size, with What Hi-Fi praising its grunt, impact and textured low-end delivery. The default Loudness setting can make the bass bloated, while very deep synth-heavy tracks may sound somewhat hollow or tame; Trueplay or disabling Loudness produces a more balanced result.
Mid
88/100
Vocals are generally clear, expressive and well projected into the room, with reviewers praising neutral midrange balance and convincing vocal presence. Some listening found the midrange a little weak or the upper mids slightly edgy, especially at higher volume or before room tuning.
Treble
89/100
The treble is widely described as airy, finely resolved and more refined than earlier Sonos speakers. It avoids sounding clinical or oppressive, although one reviewer noted some roll-off in the uppermost frequencies and another found the top end slightly shy.
Soundstage Imaging
95/100
Its spacious, enveloping presentation is the Era 300's defining strength. Multiple reviewers describe sound extending far beyond the cabinet, including convincing height effects and a large three-dimensional field with Dolby Atmos; a stereo pair adds more precise placement, though the single speaker's centre image can become diffuse or bunch up off-axis.
Dynamics
91/100
Reviewers consistently find the Era 300 punchy, fluid and able to play loudly without obvious strain. It handles both large-scale impact and smaller dynamic shifts impressively, although output limiters eventually constrain a stereo pair at higher levels.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
88/100
The all-metal enclosure is described as sturdy, compact and weighty, with reviewers also praising the design and careful presentation. Commentary concentrates on initial fit and feel rather than long-term durability, but the physical construction inspires confidence.
Value for Money
88/100
At $449 / €499 / £449, reviewers acknowledge that the Era 300 is a relatively expensive single wireless speaker, and building a stereo or surround system raises the investment further. Against close smart-speaker peers, Tech Reviews found its soundstage notably wider and more three-dimensional than Apple's HomePod, while Andrew Robinson called it the outright value winner; the price is therefore best justified by its unusually capable spatial presentation, room correction and Sonos ecosystem.
