Sonos Era 300 review: smart speaker in black

Sonos Era 300

Quick verdict from our Sonos Era 300 review: the Era 300 is Sonos’s speaker for spatial audio. It sends sound forward, sideways and up, so Dolby Atmos music sounds wide and room-filling. With regular stereo music it’s still very good, but you’re paying a premium for spatial audio, so it makes most sense if you listen on Apple Music or Amazon Music.

How we put this review together: written by Md. Enamul Arafath for TopSmartGear, using Sonos’s official Era 300 specs, independent expert reviews and verified owner feedback. This is a research-based review, not a hands-on test. Read how we review.

Who Should Buy This

The Era 300 suits music lovers who stream spatial audio and want one speaker that sounds far bigger than its size, or Sonos soundbar owners who want premium rear speakers.

Skip it if you mostly listen to regular stereo playlists or podcasts: the Sonos Era 100 costs much less and sounds excellent. Note that it plugs into the wall; it isn’t portable.

What to Expect Day to Day

You set it up in the Sonos app, and Trueplay tunes it to your room.

Alexa covers music, timers and smart home control; Sonos Voice Control only handles music but keeps voice data on the device.

What Owners Say

  • Owners praise the immersive sound with Dolby Atmos music.
  • Many use a pair as rear speakers with a Sonos soundbar.
  • Common complaints: the price, and occasional Wi-Fi or app issues.

Is It Worth the Price?

The Era 300 is a premium speaker, and Sonos has changed its price over time, so check the current price and watch for Black Friday deals. It’s worth it if you listen to a lot of spatial audio; otherwise the Era 100 is better value.

Final Verdict

The Sonos Era 300 is one of the best speakers for spatial audio at home. For most other listeners, the Sonos Era 100 gives excellent stereo sound for much less, and our best smart speakers under $100 covers cheaper picks.
