Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Glow is the better pick: it ranks #50 of 175 medium speakers by sound quality (rated 3.6/5), against #112 (rated 2.9/5) for the Ultimate Ears Wonderboom. If you want one new, the Ultimate Ears Wonderboom 4 replaces the Ultimate Ears Wonderboom and is rated 2.9/5 at $74.50.
The Soundcore Glow is the better-sounding, longer-running option. Nice light show. It is rated for 18 hours of battery against 10 for the Ultimate Ears Wonderboom. It links with other speakers (PartyCast up to 100 speakers), which the Ultimate Ears Wonderboom cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. Watch for: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume.
The Ultimate Ears Wonderboom is the lighter option. IP67 rated and floats. At 0.9 lbs (425 g) it weighs much less than the Soundcore Glow at 1.8 lbs (800 g). Watch for: Not stereo, barely any bass, recessed treble.
Buy the Soundcore Glow only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Ultimate Ears Wonderboom 4, which replaces the Ultimate Ears Wonderboom.
