Short answer: the Xiaomi Sound Party. It ranks #19 of 142 medium speakers by sound quality at $133.62; the Ultimate Ears Boom 3 ranks #92 and costs $149.99, which makes this an easy call rather than a real tradeoff.
What the Xiaomi Sound Party offers: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Several independent reviews describe a warm, generally balanced sound with clear vocals and useful bass impact when Bass Boost is off. It is also easy to carry thanks to the retractable handle. Watch for: The sound evidence is mixed rather than universally glowing. One lab review found it loud but flat and unclean with blurred treble, while others hear the Bass Boost mode as boomy upper bass that can bottom out at high volume. It is not the strongest choice for a large party: tested output is around 94dB and rivals such as the Soundcore Boom 2 play louder with deeper bass. SBC is the only Bluetooth codec and there is no aux input.
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.
Buy the Xiaomi Sound Party. 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 Xiaomi Sound Party: rated for 26 hours against 15 hours for the Ultimate Ears Boom 3.
