Short answer: the Tribit Stormbox Flow. It ranks #49 of 136 medium speakers by sound quality at $60; the Ultimate Ears Wonderboom 2 ranks #86 and costs $80, so there is not much of a tradeoff to weigh.
What the Tribit Stormbox Flow offers: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Watch for: Not stereo. Midrange and bass are weirdly recessed about 4db below 700hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
Buy the Tribit Stormbox Flow. It ranks higher for sound quality than the Ultimate Ears Wonderboom 2 and costs less, which settles it without a real tradeoff to make.
Battery life favors the Tribit Stormbox Flow: rated for 30 hours against 12 hours for the Ultimate Ears Wonderboom 2.
