Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 177 medium speakers by sound quality, rated 3.7/5, at $49.99. The Soundcore 2 ranks #105, rated 3.0/5, at $29.98, $20.01 cheaper, which does not close the gap in sound quality.
The Soundcore 2 is the longer-running, lighter option. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 12 for the Xiaomi Sound Outdoor. At 0.7 lbs (318 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. Watch for: Bass is specified only down to 70Hz, so the low end is limited.
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.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality, and saving $20.01 with the Soundcore 2 does not make up for the sound-quality gap.
