Short answer: the Teufel Rockster Go 2. It ranks #93 of 179 medium speakers by sound quality, rated 3.2/5, at $99.99; the Marshall Emberton III ranks #126, rated 2.7/5, and costs $179.99, so there is not much of a tradeoff to weigh.
The Teufel Rockster Go 2 is the better-sounding option. A light, rugged waterproof speaker with very long battery life in eco mode, stereo pairing and a tripod mount. It supports AAC Bluetooth, which the Marshall Emberton III lacks. The catch: There is no companion app or 3.5 mm input.
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 15 for the Teufel Rockster Go 2. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Teufel Rockster Go 2. 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.
