Featuring a deep and powerful bass, a clean midrange, and smooth treble, the Studio is in fact one of the very best-sounding smart speakers to pass through our labs. When playing Dolby Atmos and 3D audio content, CR’s testers report that the model provides a spacious “soundfield” that can fill a room. But the Stereo Spatial Enhancement setting adds a bit of an echo, so we recommend switching it off.

The Sonos One smart speaker has two features that make it a great choice for a wireless multiroom system: its small size and its relatively low price. The model fits unobtrusively on a shelf. And though it doesn’t offer the sheer bass response of larger speakers, it does deliver impressively detailed sound on vocals and instrumentals.

The HomePod Mini is Apple’s one remaining smart speaker, and unfortunately, it doesn’t sound nearly as good as the original HomePod, according to our testers.

That said, the HomePod Mini is great if you’re deeply immersed in Apple’s ecosystem because it offers easy integration with the Apple Music streaming service, including full voice control and multiroom capability. The Mini can also control Apple HomeKit smart home products.

Audio Pro is a Swedish company that has been making speakers since 1978. Given that history, it’s no surprise that sonically, the Audio Pro C10 MKII sits near the top of our ratings. Our testers report that it delivers bass that’s deep and impactful, though just a bit boomy, while the midrange does a fine job with both music and dialogue. There’s enough volume to fill a midsized room, and you can pair two units in stereo to improve the sound.

The Audio Pro’s multiroom capabilities can be accessed and managed through the company’s dedicated smartphone app
