Short answer: the Ultimate Ears Megaboom 3, if you are buying new. The Soundcore Glow ranks higher than it (#50 vs #108 of 175 medium speakers, 3.6/5 vs 3.0/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 3 is still sold new at $191.99.
The Soundcore Glow is the better-sounding, deeper-bass pick. Nice light show. Its bass reaches about 54Hz before falling 10dB, against 70Hz for the Ultimate Ears Megaboom 3. It supports AAC Bluetooth, which the Ultimate Ears Megaboom 3 lacks. It charges over USB-C rather than Micro USB. The catch: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume.
What the Ultimate Ears Megaboom 3 does well: IP67 rated, floats, and survives drops from up to 1 meter. The tradeoff: Not stereo, barely any bass.
Buy the Ultimate Ears Megaboom 3 new; the Soundcore Glow is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
Soundcore Glow: $80 Discontinued eBay
Pros: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Measured bass extension of 54Hz (-10dB).
Cons: 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. Discontinued and no longer sold new.

Ultimate Ears Megaboom 3: $191.99 Amazon $191.99 eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
Cons: Not stereo, barely any bass. 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 2018. Not technically a 360 speaker, only front and rear.
