Short answer: the Soundcore Motion 100. It ranks #39 of 136 medium speakers by sound quality at $47; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, so there is not much of a tradeoff to weigh.
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices.
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 Soundcore Motion 100. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, which settles it without a real tradeoff to make.
