Short answer: the Minirig 4 on measured sound quality, the Xiaomi Sound Outdoor on price. The Minirig 4 ranks #7 of 177 medium speakers, rated 4.3/5, at $229.95. The Xiaomi Sound Outdoor ranks #46, rated 3.7/5, at $49.99, $179.96 cheaper.
The Xiaomi Sound Outdoor is the tougher pick. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It is rated IP67 against Splash resistant for the Minirig 4. 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 Minirig 4 is the better-sounding, longer-running choice. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. It is rated for 30 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. Watch for: Calls itself splash resistant and has no official water rating.
Buy the Xiaomi Sound Outdoor if the price is the priority over sound quality, or the Minirig 4 if sound quality is the priority over the price.
