Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 179 medium speakers by sound quality, rated 3.7/5, at $49.99. The TOZO PA1 ranks #60, rated 3.5/5, at $39.99, $10 cheaper, not enough of a saving to outweigh the sound-quality gap.
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. 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 TOZO PA1 is the longer-running option. A budget water resistant speaker with very long battery life, app EQ and pairing with a second unit. It is rated for 25 hours of battery against 12 for the Xiaomi Sound Outdoor. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. Watch for: Bass is limited, fading by about 52Hz.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality, and the $10 saving on the TOZO PA1 is not enough to make up the difference.
