Short answer: the Tribit Stormbox Flow for battery life. It runs up to 30 hours, roughly double most rivals at about 20-24 hrs with XBass on, but it is not stereo and its midrange and bass are weirdly recessed about 4db below 700Hz. The Flip 4 has less bass than a Flip 5 and battery failures are common.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality, and the JBL Flip 4 is discontinued, so it is only available used.
Battery life favors the Tribit Stormbox Flow: rated for 30 hours against 12 hours for the JBL Flip 4.

Tribit Stormbox Flow: $79.99 Tribit eBay
Smaller model: the Tribit Stormbox Micro 2 (rated 4.5/5).
Larger models: the Tribit Stormbox Pro (ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (rated 4.5/5).
Pros: 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. Measured bass extension of 47Hz (-10dB).
Cons: 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.
