Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 179 medium speakers by sound quality, rated 3.7/5, at $49.99. The DOSS Soundbox Pro ranks #171, rated 2.1/5, at $29.99, $20 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Xiaomi Sound Outdoor is the better-sounding choice. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It charges over USB-C rather than Micro USB. Watch for: 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 DOSS Soundbox Pro is the longer-running pick. An inexpensive water resistant stereo speaker with an extra bass button, LED lights, a long rated battery and an aux input. It is rated for 20 hours of battery against 12 for the Xiaomi Sound Outdoor. It keeps a wired aux input, which the Xiaomi Sound Outdoor lacks. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. The catch: Barely any bass.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality, and saving $20 with the DOSS Soundbox Pro does not make up for the sound-quality gap.
