Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, so there is little reason to consider the other one.
The Bogasing G4 is the better-sounding, deeper-bass pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the Sonos Roam 2. It is rated for 24 hours of battery against 10 for the Sonos Roam 2. It is rated IPX7 against IPX5 for the Sonos Roam 2. Watch for: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
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 much less than the Bogasing G4 at 1.8 lbs (830 g). It supports AAC Bluetooth, which the Bogasing G4 lacks. It has an adjustable EQ, which the Bogasing G4 lacks. The catch: Exact same sound quality as the original Sonos Roam.
Buy the Bogasing G4. 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.
