Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 177 medium speakers by sound quality, rated 3.7/5, at $49.99; the Marshall Emberton II ranks #126, rated 2.7/5, and costs $114, which makes this an easy call rather than a real tradeoff.
The Marshall Emberton II is the longer-running option. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. It is rated for 30 hours of battery against 12 for the Xiaomi Sound Outdoor. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Outdoor. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Xiaomi Sound Outdoor is the better-sounding option. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. The tradeoff: Bass reach is limited for the cabinet size, with a rated lower limit of 60Hz, and the boosted bass gets somewhat uncontrolled at high levels.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Marshall Emberton II and costs less, which makes it the one to get unless you need something the other one does better.
