Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the Marshall Emberton III ranks #125, rated 2.7/5, and costs $179.99, so there is not much of a tradeoff to weigh.
The Marshall Emberton III is the longer-running pick. A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. It is rated for 32 hours of battery against 24 for the Bogasing G4. It links with other speakers (Marshall Stack), which the Bogasing G4 cannot. It has an adjustable EQ, which the Bogasing G4 lacks. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Bogasing G4 is the better-sounding option. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. It keeps a wired aux input, which the Marshall Emberton III lacks. The tradeoff: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Buy the Bogasing G4. It is rated higher for sound quality than the Marshall Emberton III and costs less, which makes it the one to get unless you need something the other one does better.
