Short answer: the Marshall Emberton III, if you are buying new. The Soundcore Glow ranks higher than it (#50 vs #126 of 175 medium speakers, 3.6/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton III is still sold new at $129.99.
The Soundcore Glow is the better-sounding, deeper-bass choice. Nice light show. Its bass reaches about 54Hz before falling 10dB, against 62Hz for the Marshall Emberton III. It supports AAC Bluetooth, which the Marshall Emberton III lacks. The tradeoff: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume.
The Marshall Emberton III is the longer-running option. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 32 hours of battery against 18 for the Soundcore Glow. It plays in stereo from a single unit, unlike the Soundcore Glow. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Marshall Emberton III, since the Soundcore Glow is discontinued and only worth hunting down used.
