Sonos Era 300 Review: Is the Dolby Atmos Speaker Worth £499?
The Era 300 is the speaker that fires sound up at your ceiling as well as across the room. Testers love what it does with Dolby Atmos music. The catch is which apps can feed it that music in the UK — and the price, which has gone up since launch rather than down.
Where the reviews line up
We built this from three places: T3, whose editor-in-chief tested it and gave it a Platinum Award; the Sonos Community forum, where owners argue about what the speaker can and cannot play; and John Lewis, where 38 buyers rate it 4.6 out of 5. All three agree the sound is the reason to buy it.
The praise is consistent. It sounds bigger than its size — T3 found it more immersive than the larger, older Sonos Five, with deep bass that does not distort. Atmos music genuinely spreads out around and above you when the track is mixed for it. And it fits a Sonos system neatly, as a stereo pair or as rear speakers behind a Sonos soundbar.
The limits are just as consistent. Atmos music only comes from certain apps. In the UK that means Apple Music and Amazon Music through the Sonos app. Spotify does not do it, and AirPlay from an iPhone does not carry Atmos to the Era 300 — owners on the forum were still asking for it in 2025. There is no 3.5 mm socket: a turntable or CD player needs Sonos's USB-C Line-In Adapter, and wired internet needs a separate adapter too.
Price is the other sticking point. It launched at £449; Sonos, John Lewis and Richer Sounds all list it at £499 today. In past sales it has dropped as low as £329, so unless you need it now, wait for a sale.
The three reviews this summary is built from
- T3Hands-on editorial test by Mat Gallagher, T3 Platinum Award. Updated June 2024.
- Sonos CommunityOwners' forum thread on Atmos over AirPlay, 19 replies, March 2025. Where the real-world limits show up.
- John Lewis4.6/5 from 38 buyer reviews, checked 10 October 2026. A small sample — US Best Buy has 1,564 for comparison.
Before the review: which apps actually play Dolby Atmos
The upward-firing tweeter only earns its keep with music mixed in Dolby Atmos. In the UK that means Apple Music and Amazon Music Unlimited, played through the Sonos app. Smart Home Sounds, a Sonos dealer, confirmed in October 2026 that Spotify still has no spatial audio. AirPlay from an iPhone plays the music in ordinary stereo, not Atmos. Your TV can send Atmos to a pair of Era 300s, but only through a Sonos Arc, Arc Ultra or Beam (Gen 2) soundbar on an HDMI eARC or ARC socket. If you mostly use Spotify, much of what you pay for here will go unused.

T3
Who they are: Mat Gallagher is T3’s editor-in-chief; his T3 profile says he began on photography magazines, worked at Time Out Beijing from 2012 and joined T3 in 2021, so this verdict carries the title’s most senior editorial sign-off.
T3 calls it “the best speaker for the money right now”. The reviewer did not expect a smaller speaker to beat the Sonos Five, but it did: the sound was bigger and more immersive, and the bass was deep and solid without distorting. On Atmos tracks, instruments are pulled apart and placed around you. He admits some purists dislike that effect, but he found it works on most music. He also rates it above Apple’s HomePod (2nd gen) for sound, although a pair of HomePods matches it for volume.
His complaints are practical. The hourglass shape will not suit every shelf, and it can only stand one way up. There is no ordinary 3.5 mm input, just a USB-C port that needs an adapter. At 4.47 kg it is awkward to move around. Trueplay’s Advanced Tuning, which now works on Android phones as well as iPhones, was fussier about background noise than on the Five and sometimes asked him to try again. One point to treat with care: T3 talks about Apple Music Atmos over AirPlay 2, but owners report that AirPlay plays in ordinary stereo — see the next source.

Who they are: Sonos Community is the brand-hosted support forum where Sonos owners report problems and staff sometimes reply; posts are unverified owner experience and skew towards people with faults, so we look for recurring issues rather than read it as typical.
This is the official Sonos owners’ forum, and this thread is where the Atmos marketing meets daily use. The original poster bought the Era 300 as “the Spatial Audio speaker with Dolby atmos” and found that playing music from an iPhone over AirPlay does not give Atmos. Sonos’s position, as he relays it, is that Apple has not let other makers’ speakers take Atmos over AirPlay 2. Other owners disagree on whether that is still true since iOS 18. One regular points out bluntly that Sonos never promised the feature, and others say Sonos does not comment on future plans.
What it means if you are buying in the UK: to hear Atmos, play Apple Music or Amazon Music inside the Sonos app, not from your phone’s music app. If you stream from Spotify or YouTube, or over Bluetooth, you get a very good stereo speaker — but not the spatial effect that costs the extra money. Only about half of the 19 replies were visible to us, and this is a forum, not a test, so read it as a list of owners’ frustrations rather than a measured verdict.

Who they are: John Lewis ratings come from its customers and are moderated by a third party, PowerReviews, before publication; free-product and syndicated brand-site reviews are labelled but counted in averages, and each review enters a £100 prize draw, so check the labels.
John Lewis is the best-known UK shop where buyers rate the Era 300, but 38 reviews is a small sample, and the page we fetched showed the score without any review text. So we can give you the number, not what people said. For a larger sample of owners, the US retailer Best Buy has 1,564 ratings on the black model. 1,366 of those are five-star and 38 are one-star, and 94% of reviewers say they would recommend it. Sound quality comes up most by a long way, mentioned 1,254 times. The complaints in the reviews we could see were about price, the Sonos app and the occasional Wi-Fi drop-out.
Sonos’s own UK review page shows 4.7/5 but no review count, so it cannot be used as evidence. Richer Sounds lists it at the same £499 with no ratings shown. It does add a free guarantee extension to six years, which is worth having on a £499 speaker.

What holds up
- Big, room-filling sound with deep, clean bass — T3 rates it above the larger Sonos Five.
- Real overhead effect on Atmos music from Apple Music and Amazon Music.
- Bluetooth button on the back, so visitors can play music without joining your Wi-Fi.
- Stereo pair or rear surrounds with a Sonos Arc, Arc Ultra or Beam (Gen 2).
- Low idle draw: 1.8 W, about £4 a year (our sum).
- Hardware microphone switch; Alexa or Sonos Voice Control.
What people complain about
- No Atmos from Spotify, and none over AirPlay — owners still asking in 2025.
- No 3.5 mm socket; a record player needs the USB-C Line-In Adapter.
- £499 now, up from £449 at launch, with no price cut at the main UK shops today.
- Bluetooth and line-in switch off when it is used as a rear surround.
- No Google Assistant, and the hourglass shape only stands one way up.
- App niggles and Wi-Fi drop-outs crop up in buyer reviews.
Who it actually suits
Buy it if you pay for Apple Music or Amazon Music Unlimited and want one speaker that fills a living room. It is also the natural choice if you already have a Sonos soundbar and want rear speakers that add height to films. That soundbar plugs into a TV such as the LG C4 OLED or the Hisense 55U7S Pro through HDMI eARC. The Era 300 cannot do that job on its own.
Look elsewhere if you mainly use Spotify, or you want a speaker for a kitchen or bedroom. The Sonos Era 100 costs much less and fits the same Sonos system. If you mostly want Alexa, a timer and the radio, the Echo Dot Max costs a fraction of the price. And if you are not in a hurry, wait for a sale: it has been as low as £329 before.
What we could not check
- The three videos. We confirmed each one by finding its title and link in search listings, not by watching it. The listings did not name the channels.
- Exact dimensions. Sonos says 185 mm high × 160 mm deep; Richer Sounds says 160 mm high × 185 mm deep. Both give 260 mm wide. Measure your shelf for 185 mm both ways.
- Bluetooth version. Sonos’s UK page says 5.3. What Hi-Fi and Smart Home Sounds say 5.0. We could not settle it.
- When the price rose. What Hi-Fi gives £449 as the launch price, and Richer Sounds still mentions it. Today it is £499 everywhere we checked. We could not find when the price went up.
- Who the seller is. The John Lewis and Richer Sounds pages we read did not show a third-party seller. We checked no marketplace listings (Amazon, Argos, Currys, Very or B&Q’s website).
- Atmos over AirPlay since iOS 18. Owners on the forum disagree on whether Apple now allows it. In the posts we could see, Sonos had not said it supports it.
- What John Lewis buyers said. The page showed 4.6/5 from 38 but no review text. Sonos’s own 4.7/5 has no count at all.
- Power when playing. Sonos only publishes the 1.8 W idle figure. Our £4.15 a year covers idle only, not listening time.
- Independent sound measurement. We found no published lab measurements of frequency response or noise from a UK testing body. Which? has a page for the speaker, but we did not see its score.
