Sonos Era 300 Review: The Smart Speaker That Actually Justifies the Price

By Tech Editorial | April 2026

The Sonos Era 300 wins because it sounds like a proper speaker, not a voice assistant with a driver bolted in. If you want one smart speaker that can handle music, Wi‑Fi streaming, Bluetooth, Alexa, AirPlay 2 and Sonos multi-room without sounding ordinary, this is the one to beat.

Our picks at a glance

Based on hands-on research, expert review consensus (RTings, Wirecutter, relevant subreddits), and current pricing.

Best overall: Sonos Era 300

Sonos Era 300 — £449.00

This is the rare smart speaker that sounds worth the money when you actually want to sit and listen. With a 8.2 score, six drivers and Dolby Atmos Music support, the Era 300 gives you a wider, more enveloping presentation than the usual Alexa box and plays especially well in a living room or part of a Sonos system.

Why we picked it:

• Six-driver layout with forward, side and upward firing sound makes spatial audio feel genuinely bigger.
• Trueplay tuning helps the speaker adapt to your room instead of forcing you to work around it.
• Wi‑Fi, Bluetooth, Alexa and AirPlay 2 make it flexible without turning it into a compromise machine.

The trade-off: it is expensive, and it comes alive more at higher volume than at background-listening levels.

If you want the one-box Sonos speaker that makes spatial audio feel like a feature, buy the Era 300 here.

Best upgrade: Apple HomePod 2

Apple HomePod 2 — £299

The premium here is ecosystem fit, not outright flexibility. The HomePod 2 is the cleaner buy if you live in Apple Music, use an iPhone and want a speaker that disappears into the background while still sounding excellent.

Worth it if: you are all-in on Apple and care more about simple, polished listening than Sonos multi-room or broader input options.

Best budget pick: Sonos Era 100

Sonos Era 100 — £249

This is the sensible Sonos buy for most people who want the brand, the app and the streaming convenience without spending Era 300 money. It is smaller, cheaper and less ambitious, but it still gets you strong room-filling sound and the Sonos ecosystem.

Worth it if: you want a compact smart speaker for a bedroom, kitchen or office and do not need the Era 300’s spatial trickery.

Also worth considering

Bose SoundLink Flex (2nd Gen) — £109

This is the speaker you buy when durability matters more than smart-speaker features. The IP67 rating, multipoint support and PositionIQ tuning make it a great travel or garden option, but it cannot match the Era 300 for scale or cleverness.

JBL Flip 7 — £119

The Flip 7 is the easiest recommendation for people who want a small Bluetooth speaker they can toss into a bag without worrying about it. It is tougher than the Bose in a few ways, but it still lives in portable-speaker territory, not proper room audio.

Bang & Olufsen Beosound A1 (3rd Gen) — £226.70

This is the design-led choice that still sounds grown-up. It is more portable and more refined than cheap travel speakers, but the price is doing a lot of the work here.

Wharfedale Diamond 12.1i — £249

These are for people building a real hi-fi setup, not a smart one. They sound cleaner and more stereo-correct than an all-in-one speaker, but you will need an amp and you lose the convenience of a wireless assistant speaker.

Edifier R1280DBs — £139

This is the value pick for a desk, bedroom or TV setup. The inputs are the point here: optical, coaxial, RCA and Bluetooth make it easy to live with, but this is still a budget speaker, not a statement one.

How we chose

We prioritised sound quality, spatial audio performance, connectivity and real-world flexibility over spec-sheet theatre. For the Era 300, that means weighing the six-driver design, Trueplay tuning and multi-room Sonos ecosystem against the obvious downsides: price and the need to turn it up for the best effect. We cross-checked current availability and pricing against recent expert coverage from RTINGS, WIRED, What Hi-Fi? and CNET.

Frequently asked questions

Is the Sonos Era 300 worth buying over the Era 100? Yes, if you want a bigger, more immersive speaker and you will actually use spatial audio. The Era 100 is the better value if you just want a good smart speaker for normal listening.

Why is the Era 300 so expensive? You are paying for six drivers, spatial audio processing, room tuning and the Sonos ecosystem. That only makes sense if you care about sound quality enough to notice the difference.

Can you use the Era 300 with a turntable? Yes, with the Sonos line-in adapter. That makes it far more flexible than a typical smart speaker.

Do you need to place it carefully? Less than you would with most speakers, thanks to Trueplay, but it still sounds best when given room to breathe and volume to work with.
