Short answer: the Soundcore Glow. It ranks #43 of 136 medium speakers by sound quality at $80; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, which makes this an easy call rather than a real tradeoff.
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 Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the Soundcore Glow. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, which settles it without a real tradeoff to make.
The Ultimate Ears Megaboom 4 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
