Short answer: the Xiaomi Sound Outdoor. It ranks #46 of 177 medium speakers by sound quality, rated 3.7/5, at $49.99; the Tribit Stormbox 2 ranks #104, rated 3.0/5, and costs $69.99, so there is little reason to consider the other one.
The Xiaomi Sound Outdoor is the better-sounding pick. 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 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.
The Tribit Stormbox 2 is the longer-running choice. A light, waterproof everyday speaker with a long rated battery and an Xbass mode that fills out the low end. It is rated for 24 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. The catch: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Tribit Stormbox 2 and costs less, so only choose the other one for a particular feature it does better.
