Short answer: the Tribit Stormbox Flow. It ranks #49 of 136 medium speakers by sound quality at $60; the Sony SRS-XB20 ranks #94 and costs $129, which makes this an easy call rather than a real tradeoff.
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 Sony SRS-XB20 offers: IPX5 rated pill shape slides easily into a bag. 12 hour battery life. Watch for: Sounds thin at higher volumes. Bass falls away quickly.
Buy the Tribit Stormbox Flow. It ranks higher for sound quality than the Sony SRS-XB20 and costs less, so there is no real case for the other one.
Battery life favors the Tribit Stormbox Flow: rated for 30 hours against 12 hours for the Sony SRS-XB20.
