Short answer: the Xiaomi Sound Party. It ranks #20 of 182 medium speakers by sound quality, rated 4.1/5, at $135.84. The Tribit Stormbox Flow ranks #58, rated 3.5/5, at $79.99, $55.85 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Xiaomi Sound Party is the better-sounding pick. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. The catch: The sound evidence is mixed rather than universally glowing.
The Tribit Stormbox Flow is the deeper-bass, lighter pick. A waterproof speaker with very long battery life, a carry handle, stereo pairing and a port that charges your phone. Its bass reaches about 47Hz before falling 10dB, against 54Hz for the Xiaomi Sound Party. At 1.4 lbs (657 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). It supports AAC Bluetooth, which the Xiaomi Sound Party lacks. Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
Buy the Xiaomi Sound Party. It is rated higher for sound quality, and saving $55.85 with the Tribit Stormbox Flow does not make up for the sound-quality gap.
