Short answer: the Soundcore 2. It ranks #81 of 136 medium speakers by sound quality at $29.98; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, which makes this an easy call rather than a real tradeoff.
What the Soundcore 2 offers: 24+ hour battery life from a 5200mAh cell. Very light (0.8 lb) and compact. IPX7 rated with a soft, grippy silicone coating. Watch for: Bass doesn’t go as deep as others
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 2. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, so there is no real case for the other one.
There is a real battery-life gap here: the Soundcore 2 is rated for 24 hours, the Ultimate Ears Boom 3 only 15 hours.
