Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, so there is little reason to consider the other one.
The EarFun Uboom L is the better-sounding, deeper-bass option. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. 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 IP67 against IPX5 for the Sonos Roam 2. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
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 EarFun Uboom L at 1.4 lbs (650 g). The catch: Exact same sound quality as the original Sonos Roam.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Sonos Roam 2 and costs less, which makes it the one to get unless you need something the other one does better.
