Overview
A compact, two cable Sonos soundbar with Dolby Atmos support, Sonos app control, Trueplay room tuning, and AirPlay 2 streaming, sized more for bedrooms and secondary rooms than large living rooms.
- Dolby Atmos support added over the original Sonos Beam
- Trueplay tuning calibrates sound to the room through the Sonos app
- Streams music, radio, podcasts and audiobooks independent of the TV
- Setup with two cables, expandable into a full Sonos multiroom system
Who it's for
Works well for a bedroom, office or apartment living room, and for anyone who wants a soundbar that also functions as a standalone music speaker through the Sonos app. Not the pick for a large living room expecting room filling volume, where the bigger Sonos Arc fits better.
What buyers say
From Amazon customer reviews.
Buyers consistently praised the clear dialogue, quick app based setup and surprisingly wide soundstage for its size, with several noting that running Trueplay tuning made a noticeable difference to the bass. The recurring caveat is that it's sized for a bedroom or office, and while one reviewer said it works fine in a living room, another felt it lacked the room filling presence expected from a main living room system, pointing toward the larger Sonos Arc for that use.
Strengths and trade-offs
Drawn from this product's published specifications.
- Clear dialogue and wide soundstage for its size
- Quick app based setup
- Plays music standalone via app, AirPlay or voice
- Expands into a full Sonos system
- Not room filling enough for a large living room
- Tied to the Sonos app ecosystem
Performance notes
Trueplay uses the Sonos app and a phone's microphone to measure how sound bounces around the room and adjusts the tuning accordingly, and several reviewers said running it made a noticeable difference to the bass. Dolby Atmos height cues come from angled internal drivers rather than physical up firing speakers, which reviewers describe as convincing for a soundbar this size. Because it runs through the Sonos app and ecosystem rather than a universal remote setup, it also stays standalone capable, playing music, radio or podcasts through the same speaker when the TV is off.
