The best multiroom audio without Sonos for most UK homes is a WiiM streamer — the WiiM Pro or Pro Plus cost roughly £150–£220, plug into speakers or an amp you already own, and sync audio across rooms via AirPlay 2, Chromecast, or WiiM's own protocol. If you already own a hi-fi system or AV receiver, Yamaha MusicCast or Denon HEOS extend that same brand's amplifiers and soundbars into a synced multiroom setup. And if you don't want to spend anything at all, Google Home speaker groups and Apple AirPlay 2 both do genuine multiroom audio for free, provided every speaker supports the same protocol. The right pick depends less on sound quality — most of these are close — and more on what speakers, streaming services, and smart assistant you already use.
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.
| System | Typical UK price | Best for | Key protocols |
|---|---|---|---|
| WiiM Pro / Pro Plus | ~£150–£220 | Adding multiroom to existing speakers/amps | AirPlay 2, Chromecast, Alexa Cast, Spotify Connect |
| Yamaha MusicCast | ~£249 (MusicCast 20) – £499 (MusicCast 50) | Households with a Yamaha AV receiver or soundbar | Wi-Fi (MusicCast), AirPlay 2, Bluetooth |
| Denon HEOS | ~£250–£600 depending on model | Denon/Marantz hi-fi owners | Wi-Fi (HEOS), AirPlay 2, Bluetooth |
| Bluesound (BluOS) | ~£279 (Pulse Flex) – £1,000+ (Pulse) | Hi-res audiophile streaming | BluOS, AirPlay 2, aptX HD Bluetooth |
| Google Home speaker groups | Free (uses existing Chromecast-built-in speakers) | Google/Nest households | Google Cast |
| Apple AirPlay 2 | Free (uses existing AirPlay 2 speakers) | All-Apple households | AirPlay 2 |
| Amazon Echo multiroom | From ~£35 per Echo Dot | Budget, voice-first setups | Alexa Cast |
Does WiiM work with speakers I already own?
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.
Is Yamaha MusicCast or Denon HEOS better than Sonos?
Neither beats Sonos outright on app polish, but both offer 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. Denon HEOS does the same for Denon and Marantz separates. Both support AirPlay 2 and Bluetooth alongside their own multiroom protocol, and both are better value than Sonos if you're building around an AV receiver rather than standalone wireless speakers. Neither app is quite as slick as Sonos's, and third-party accessory support is thinner — but for anyone already invested in one of these two hi-fi brands, adding multiroom is close to a no-brainer.
What about Bluesound 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.
Can I get multiroom audio for free with Google or Apple?
Yes, provided your existing speakers already support the right protocol. 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. 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. The catch with both free routes is consistency — mixing brands works, but latency and grouping reliability can vary more than with a single-vendor system like Sonos or WiiM.
Is Amazon Echo multiroom a real Sonos alternative?
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.
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.
