Short answer: the Tribit Stormbox Flow. It ranks #62 of 175 medium speakers by sound quality (rated 3.5/5) at $79.99 and is still sold new; the Ultimate Ears Wonderboom ranks #112 (rated 2.9/5) and is discontinued, so it is only an option used. The Ultimate Ears Wonderboom’s replacement, the Ultimate Ears Wonderboom 4, is rated 2.9/5 at $74.50.
The Tribit Stormbox Flow is the better-sounding, longer-running pick. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). It is rated for 30 hours of battery against 10 for the Ultimate Ears Wonderboom. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. It charges over USB-C rather than Micro USB. The tradeoff: Midrange and bass are weirdly recessed about 4db below 700Hz.
The Ultimate Ears Wonderboom is the lighter option. IP67 rated and floats. At 0.9 lbs (425 g) it weighs noticeably less than the Tribit Stormbox Flow at 1.4 lbs (657 g). The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality; the Ultimate Ears Wonderboom is no longer sold new.

The Two Speakers In Full
Tribit Stormbox Flow: $79.99 Tribit $79.99 eBay
Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Pro (larger model, ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (larger model, rated 4.5/5). See every Tribit Stormbox generation.
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.
