Short answer: the Soundcore Glow. It ranks #43 of 136 medium speakers by sound quality at $80; the Marshall Emberton III ranks #99 and costs $165.04, so there is little reason to consider the other one.
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 Marshall Emberton III offers: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Emberton II except having the treble turned down a little bit.
Buy the Soundcore Glow. It ranks higher for sound quality than the Marshall Emberton III and costs less, which settles it without a real tradeoff to make.
Battery life favors the Marshall Emberton III: rated for 32 hours against 18 hours for the Soundcore Glow.
