Short answer: the Soundcore Boom 3i. It ranks #31 of 177 medium speakers by sound quality, rated 4.0/5, at $118.99; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, so there is little reason to consider the other one.
The Soundcore Boom 3i is the better-sounding, deeper-bass pick. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the Sonos Roam 2. It is rated for 16 hours of battery against 10 for the Sonos Roam 2. It is rated IP68 against IPX5 for the Sonos Roam 2. The catch: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Sonos Roam 2 is the lighter choice. 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 much less than the Soundcore Boom 3i at 1.7 lbs (783 g). Watch for: Exact same sound quality as the original Sonos Roam.
Buy the Soundcore Boom 3i. It is rated higher for sound quality than the Sonos Roam 2 and costs less, so only choose the other one for a particular feature it does better.
