Our Verdict

Ultimate Ears WONDERBOOM 2

Sonos Roam/Roam SL

Depending on your listening habits, you may prefer either the Ultimate Ears WONDERBOOM 2 or the Sonos Roam/Roam SL. The Sonos Roam variant has built-in voice assistant support over Wi-Fi, and it comes with more sound enhancement features, including room correction and bass and treble adjustments. However, the Ultimate Ears has a better soundstage performance and a longer battery life and gets louder. It's also advertised to float in water.
