Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 177 medium speakers by sound quality, rated 3.7/5, at $49.99; the Walla Sound ranks #163, rated 2.2/5, at $49.99. With prices this close, go by the sound-quality ranking rather than the cost.
The Xiaomi Sound Outdoor is the better-sounding, longer-running pick. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It is rated for 12 hours of battery against 8 for the Walla Sound. It is rated IP67 against IPX5 for the Walla Sound. It charges over USB-C rather than Micro USB. 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 Walla Sound is the lighter choice. A small shockproof speaker with an aux input, microSD playback and a built in microphone. At 0.7 lbs (300 g) it weighs much 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 catch: No bass, gets distorted when turned up.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Walla Sound at the same price, which makes it the one to get unless you need something the other one does better.
