Short answer: the Soundcore Glow. It ranks #43 of 136 medium speakers by sound quality at $80; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, so there is not much of a tradeoff to weigh.
What the Soundcore Glow offers: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Watch for: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume. Light effects and bass-boost noticeably shorten battery life. USB-C port doesn’t support power-bank charging.
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 Glow. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, so the other one has nothing left to offer.
