BEST SOUND/$
190W of Class D power driving two tweeters and a 6.5-inch woofer — won What Hi-Fi?'s best home wireless speaker award.
WORKS ANY PHONE
AirPlay 2 + Google Cast together — the rare speaker that groups from an iPhone or an Android, no ecosystem lock-in.
DOUBLES FOR TV
HDMI ARC input handles TV and movie audio — the most versatile single speaker in the comparison.
STREAMING BUILT IN
Spotify and Tidal Connect onboard alongside Bluetooth 5.0 — no phone tether needed to stream.
UNDERCUTS THE FIVE
Hits harder than the Sonos Five while costing ~$250 less ($349 vs $599).

  The catch — co-equal billing, always

Its multiroom is a side act. Audio Pro groups only across its own speakers, on an app nowhere near Sonos's polish. Buy the C20 for how one speaker sounds in one room — not to wire a whole house together.

Dealbreaker? Runner-up №1 — the Sonos Era 300 if whole-home grouping is the point ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Runners-up — if your needs differ

Adjacent verdicts — same method

Traps — this verdict avoids

Trap 01

Ecosystem lock-in

Sonos, Apple, Denon HEOS and Alexa multiroom groups don't mix. Your first speaker commits the household to one of four incompatible ecosystems — you can't put a Sonos and a HomePod in the same group, ever.

Trap 02

Bluetooth ≠ multiroom

Real room-to-room sync rides on Wi-Fi. Bluetooth-only speakers can't synchronize across rooms at all, and any setup of 4+ speakers wants a mesh network to stay locked together.

Trap 03

The hi-res illusion

24-bit/192kHz hi-res needs a compatible speaker AND a Tidal, Qobuz or Amazon Music HD plan. Budget speakers still cap at 16-bit/48kHz no matter what you stream into them.
