Short answer: the Tribit Stormbox Flow. It ranks #49 of 136 medium speakers by sound quality at $60; the Sony SRS-XB30 ranks #104 and costs $199, 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-XB30 offers: IPX5 rated. Doubles as a power bank for charging your phone. Long claimed battery life (up to 24 hours at moderate volume). Watch for: Muffled sound, worse than a XB20
Buy the Tribit Stormbox Flow. It ranks higher for sound quality than the Sony SRS-XB30 and costs less, which settles it without a real tradeoff to make.
Skip the Sony SRS-XB30 if sound quality matters to you. It ranks near the bottom of the 136 medium speakers.
