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 II ranks #126, rated 2.7/5, and costs $114, so there is little reason to consider the other one.
What the Marshall Emberton II does well: A tough waterproof speaker with Marshall styling, a very long battery and quick charging. 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, louder choice. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. Alan Ross Reviews measured it at 100dB at full volume, against 88dB for the Marshall Emberton II. It keeps a wired aux input, which the Marshall Emberton II lacks. The catch: 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 II and costs less, so only choose the other one for a particular feature it does better.
