Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 179 medium speakers by sound quality, rated 3.7/5, at $49.99. The Oontz Angle 3 Ultra ranks #163, rated 2.2/5, at $39.99, $10 cheaper, which does not close the gap in sound quality.
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.
The Oontz Angle 3 Ultra is the longer-running, lighter pick. A cheap, very light waterproof speaker with a long battery and plenty of features for the money. It is rated for 20 hours of battery against 12 for the Xiaomi Sound Outdoor. At 0.9 lbs (400 g) it weighs noticeably less than the Xiaomi Sound Outdoor at 1.3 lbs (597 g). It keeps a wired aux input, which the Xiaomi Sound Outdoor lacks. The tradeoff: Very little bass with horrible upper bass thud at higher levels.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality, and the $10 saving on the Oontz Angle 3 Ultra is not enough to make up the difference.
