Short answer: the Marshall Emberton II, if you are buying new. The Soundcore Glow ranks higher than it (#48 vs #127 of 179 medium speakers, 3.6/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton II is still sold new at $151.99.
The Marshall Emberton II’s strengths: A 30-hour battery life, among the best in its class, with a 20-minute quick charge good for 4 hours, plus an IP67 rating and a durable rubbery build made from 50% recycled plastic. But: it has a strange, unnatural echo-like coloration, bass that doesn’t dig as deep as competitors, sound that only fires front and rear rather than truly 360 degrees, and it isn’t very loud.
In its favor, the Soundcore Glow: A nice light show, with the treble boosted about 7db, though it isn’t technically a 360 speaker, only firing front and rear. Against it: its bass falls off quickly at louder volumes leaving mostly treble with distortion on bass-heavy tracks at full volume, the light effects and bass boost noticeably shorten battery life, and the USB-C port doesn’t support power-bank charging.
Buy the Marshall Emberton II, since the Soundcore Glow is discontinued and only worth hunting down used.
Battery life favors the Marshall Emberton II: rated for 30 hours against 18 hours for the Soundcore Glow.
