These sit in different size classes, so this is not a straight ranking comparison. The Tribit Stormbox Micro 3 ranks #6 of 62 small speakers by sound quality at $56.76; the Xiaomi Sound Outdoor ranks #46 of 179 medium speakers by sound quality at $49.99.
The Tribit Stormbox Micro 3 is the longer-running, lighter choice. A tough strap on mini speaker with full waterproofing, a 24 hour battery and a power bank output. It is rated for 24 hours of battery against 12 for the Xiaomi Sound Outdoor. At 0.7 lbs (330 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 tradeoff: Bass is thuddy and distorted by default and needs EQ.
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 3 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 3 at $56.76 for a small speaker, or the Xiaomi Sound Outdoor at $49.99 for a medium speaker instead.
