Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 177 medium speakers by sound quality, rated 3.7/5, at $49.99; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, so there is not much of a tradeoff to weigh.
The Xiaomi Sound Outdoor is the better-sounding, tougher choice. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It is rated IP67 against IPX5 for the Sonos Roam 2. The tradeoff: Bass reach is limited for the cabinet size, with a rated lower limit of 60Hz, and the boosted bass gets somewhat uncontrolled at high levels.
The Sonos Roam 2 is the lighter pick. A small Wi-Fi and Bluetooth speaker with water resistance, Alexa built in and Sonos multiroom support. At 0.9 lbs (429 g) it weighs noticeably less than the Xiaomi Sound Outdoor at 1.3 lbs (597 g). It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. The catch: Exact same sound quality as the original Sonos Roam.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Sonos Roam 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
