Short answer: the Soundcore Glow. It ranks #43 of 136 medium speakers by sound quality at $80; the Ultimate Ears Boom 4 ranks #88 and costs $105, 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 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
Buy the Soundcore Glow. It ranks higher for sound quality than the Ultimate Ears Boom 4 and costs less, which settles it without a real tradeoff to make.
