Short answer: the Miatone Boompro. It ranks #16 of 179 medium speakers by sound quality, rated 4.2/5, at $35.99; the Xiaomi Sound Outdoor ranks #46, rated 3.7/5, and costs $49.99, so there is not much of a tradeoff to weigh.
The Miatone Boompro is the better-sounding, longer-running option. A cheap waterproof speaker with very well balanced sound, even at full volume, and a 16 hour battery. It is rated for 16 hours of battery against 12 for the Xiaomi Sound Outdoor. Watch for: Slightly less bass extension than higher ranked speakers.
What the Xiaomi Sound Outdoor does well: An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. The catch: 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 Miatone Boompro. It is rated higher for sound quality than the Xiaomi Sound Outdoor and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
