These sit in different size classes, so this is not a straight ranking comparison. The Tribit Stormbox Micro 2 ranks #1 of 62 small speakers by sound quality at $35.39; the Xiaomi Sound Outdoor ranks #46 of 179 medium speakers by sound quality at $49.99.
The Tribit Stormbox Micro 2 is the lighter option. An excellent sounding small speaker, with surprisingly deep bass for its size and a strap that holds it on a bike or backpack. At 0.7 lbs (317 g) it weighs much less than the Xiaomi Sound Outdoor at 1.3 lbs (597 g). It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. The catch: Finicky phone charging, which doesn’t usually work.
The case for the Xiaomi Sound Outdoor: An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. It links with other speakers (Speakersync, up to 100 speakers), which the Tribit Stormbox Micro 2 cannot. 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 Tribit Stormbox Micro 2 ($35.39) for a small speaker; the Xiaomi Sound Outdoor ($49.99) suits a medium speaker instead.
