Short answer: the Tronsmart T8. It ranks #54 of 182 medium speakers by sound quality, rated 3.6/5, at $49.99; the Marshall Emberton III ranks #128, rated 2.7/5, and costs $179.99, so there is little reason to consider the other one.
The Tronsmart T8 is the better-sounding pick. An affordable waterproof speaker with upward firing drivers that spread sound around, plus lights, app EQ, an aux input and stereo pairing. It keeps a wired aux input, which the Marshall Emberton III lacks. The catch: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass.
The Marshall Emberton III is the longer-running choice. A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. It is rated for 32 hours of battery against 18 for the Tronsmart T8. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Tronsmart T8. It is rated higher for sound quality than the Marshall Emberton III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
