Short answer: the Bogasing M5. It ranks #61 of 177 medium speakers by sound quality, rated 3.5/5, at $52.99; the Marshall Emberton III ranks #125, rated 2.7/5, and costs $179.99, so there is little reason to consider the other one.
The case for the Marshall Emberton III: A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. It plays in stereo from a single unit, unlike the Bogasing M5. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Bogasing M5 is the better-sounding choice. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. It keeps a wired aux input, which the Marshall Emberton III lacks. The tradeoff: Front/rear driver configuration.
Buy the Bogasing M5. It is rated higher for sound quality than the Marshall Emberton III and costs less, so only choose the other one for a particular feature it does better.
