Short answer: the Bogasing M5. It ranks #55 of 142 medium speakers by sound quality at $45.59; the Sonos Roam 2 ranks #74 and costs $179, which makes this an easy call rather than a real tradeoff.
What the Bogasing M5 offers: Compact enough for a backpack side pocket at under 1.7 lb. Up to 30 hours of battery life. USB-C charging - no proprietary cable to lose. Watch for: Front/rear driver configuration. Use bass mode for the flattest response. Sounds thin in the midrange. Hot treble and rolled off bass in default mode. Treble a bit rolled off in bass mode.
What the Sonos Roam 2 offers: Very neutral. Additional button for pairing instead of being shared with power button Watch for: Exact same sound quality as the original Roam. Bass extension isn’t very good. Not stereo. Gets distorted as you turn up the bass.
Buy the Bogasing M5. It ranks higher for sound quality than the Sonos Roam 2 and costs less, so the other one has nothing left to offer.
If battery life is a priority, the Bogasing M5 is rated for 30 hours versus 10 hours for the Sonos Roam 2.
