Short answer: the Bogasing M5. It ranks #61 of 177 medium speakers by sound quality, rated 3.5/5, at $52.99; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, which makes this an easy call rather than a real tradeoff.
The Bogasing M5 is the longer-running, tougher choice. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. It is rated for 30 hours of battery against 10 for the Sonos Roam 2. It is rated IPX7 against IPX5 for the Sonos Roam 2. It keeps a wired aux input, which the Sonos Roam 2 lacks. The tradeoff: Front/rear driver configuration.
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 Bogasing M5 at 1.7 lbs (757 g). Watch for: Exact same sound quality as the original Sonos Roam.
Buy the Bogasing M5. 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.
