How We Picked These Sonos Alternatives
We compared each system on the criteria that matter for a Sonos switch: whether it works with speakers or amps you already own rather than forcing a new purchase, which streaming protocols and services it supports, typical UK price, and how tightly it ties you into a single manufacturer's ecosystem. We excluded multiroom systems with no meaningful UK retail availability.
Why look beyond Sonos?
Sonos remains the most polished multiroom app on the market, but it isn't the only option, and for some households it isn't the best fit. Sonos speakers are proprietary — you generally can't add a non-Sonos amp or existing hi-fi speakers into a Sonos multiroom group without extra hardware. The alternatives below are looser: several let you keep speakers you already own, some are free if you're already inside the Google or Apple ecosystem, and a couple offer wider hi-res audio support than Sonos does. Our guide to setting up multiroom audio covers the general principles if you're starting from scratch.
The best multiroom systems without Sonos in 2026
1. WiiM Pro / Pro Plus — best overall for retrofitting existing speakers
Yes — that's the entire point of WiiM. The WiiM Pro and Pro Plus are small streaming boxes, typically £150–£220 in the UK, that connect to any amplifier or powered speaker via optical, coaxial, or analogue output, then add Wi-Fi streaming and multiroom sync on top. Each WiiM unit supports Spotify Connect, TIDAL Connect, AirPlay 2, Google Cast, Alexa Cast, and Roon Ready, and multiple WiiM devices can be grouped for synchronised playback with sub-150 microsecond timing accuracy, according to WiiM's own product specifications. Because it works over Wi-Fi rather than a proprietary mesh, you can also mix WiiM units with existing AirPlay 2 or Google Cast speakers in the same multiroom group. It's the cheapest way to retrofit multiroom onto an existing stereo, soundbar, or bookshelf speakers without buying new speakers outright.
2. Yamaha MusicCast — best for existing Yamaha AV systems
Yamaha MusicCast doesn't beat Sonos outright on app polish, but it offers something Sonos doesn't: a direct line into a full hi-fi and home cinema ecosystem from the same brand. Yamaha MusicCast spans wireless speakers, soundbars, and AV receivers under one app, so a MusicCast 20 speaker (around £249) in the bedroom can sync with a full MusicCast-enabled AV receiver driving the lounge system. It supports AirPlay 2 and Bluetooth alongside its own multiroom protocol, and is better value than Sonos if you're building around an AV receiver rather than standalone wireless speakers. The app isn't quite as slick as Sonos's, and third-party accessory support is thinner — but for anyone already invested in Yamaha's AV ecosystem, adding multiroom is close to a no-brainer.
3. Denon HEOS — best for Denon/Marantz systems
Denon HEOS does the same job for Denon and Marantz separates — it extends a Denon or Marantz amplifier or soundbar into a synced multiroom system under one app. Like MusicCast, Denon HEOS supports AirPlay 2 and Bluetooth alongside its own multiroom protocol, and is better value than Sonos if you're building around an AV receiver rather than standalone wireless speakers. The app is less polished than Sonos's and third-party accessory support is thinner, but for existing Denon or Marantz owners, adding multiroom this way is close to a no-brainer.
4. Bluesound (BluOS) — best for hi-res audio
Bluesound's BluOS platform is the strongest option here for listeners who care about high-resolution audio above all else. BluOS supports MQA decoding, 24-bit/192kHz playback, and Roon integration, and Bluesound speakers such as the Pulse Flex (from around £279) or the flagship Pulse pair Wi-Fi multiroom sync with genuinely audiophile-grade output, according to Bluesound's product specifications. It also supports AirPlay 2 and aptX HD Bluetooth, so it slots into a mixed-brand household without much friction. The trade-off is price: a full BluOS system costs noticeably more per room than WiiM or MusicCast, and the app, while capable, is less consumer-friendly than Sonos's. This is the pick for a dedicated listening room rather than whole-home background music.

5. Google Home speaker groups — best free option for Google/Nest households
Any speaker with Chromecast built-in — including many TVs, soundbars, and smart speakers — can be added to a Google Home speaker group at no extra cost, letting you play synced audio across every room from the Google Home app or by voice. The catch is consistency: mixing brands works, but latency and grouping reliability can vary more than with a single-vendor system like Sonos or WiiM.
6. Apple AirPlay 2 — best free option for Apple households
Apple users get the same result through AirPlay 2: any AirPlay 2-certified speaker, including many from Sonos, Bose, and Yamaha alongside Apple's own HomePod mini, can join a multiroom group directly from the Music or Control Centre app. Our best AirPlay 2 speakers UK guide lists compatible hardware if you're starting from nothing. As with Google Home groups, mixing brands works, but latency and grouping reliability can vary more than with a single-vendor system.
7. Amazon Echo multiroom — best budget, voice-first option
For a budget, voice-first setup, yes. Amazon's Alexa multiroom music groups let you link any combination of Echo devices — including Echo Dots from around £35 each — so a single voice command plays the same track in every room simultaneously. Our Alexa multiroom music setup guide walks through the process. Sound quality on entry-level Echo Dots is modest compared with dedicated hi-fi speakers, but for background music triggered by voice rather than critical listening, it's the cheapest way into synced multiroom audio, and it integrates cleanly with smart home routines if you're already running Alexa elsewhere in the house.
Who should skip a non-Sonos system and stick with Sonos?
If you want the single most polished app experience, the widest range of compatible speakers and soundbars, and don't mind paying a premium for that convenience, Sonos itself is still worth sticking with. The alternatives above earn their place mainly when you already own speakers, an AV receiver, or an ecosystem (Google or Apple) that Sonos can't cleanly absorb — if none of that applies to you, a straight Sonos setup remains the simplest choice.
Which non-Sonos multiroom system should you buy?
If you're starting from scratch and want the lowest-cost, most flexible option, buy a WiiM Pro and pair it with speakers or an amp you already own. If you already have a Yamaha or Denon/Marantz AV receiver, stick with that brand's ecosystem — MusicCast or HEOS — rather than starting a second, unrelated system. Audiophiles chasing the best possible sound quality should look at Bluesound, accepting the higher per-room cost. And if you just want free multiroom using speakers or Echo devices you already own, Google Home groups, AirPlay 2, and Alexa multiroom all do the job without spending anything extra.
