Short answer: the Bogasing M5. It ranks #55 of 142 medium speakers by sound quality at $45.59; the KEF Muo gen2 ranks #76 and costs $249.99, 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 KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
Buy the Bogasing M5. It ranks higher for sound quality than the KEF Muo gen2 and costs less, so the other one has nothing left to offer.
