Short answer: the Bogasing M5. It ranks #55 of 142 medium speakers by sound quality at $45.59; the Ultimate Ears Boom 3 ranks #92 and costs $149.99, which makes this an easy call rather than a real tradeoff.
What the Ultimate Ears Boom 3 offers: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp Watch for: Not stereo, barely any bass, recessed treble. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.
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.
Buy the Bogasing M5. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, which settles it without a real tradeoff to make.
Battery life favors the Bogasing M5: rated for 30 hours against 15 hours for the Ultimate Ears Boom 3.
