Short answer: the Tribit Stormbox Flow. It ranks #62 of 175 medium speakers by sound quality, rated 3.5/5, at $79.99; the Ultimate Ears Megaboom 3 ranks #108, rated 3.0/5, and costs $191.99, so there is not much of a tradeoff to weigh.
The Tribit Stormbox Flow is the better-sounding, deeper-bass pick. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). Its bass reaches about 47Hz before falling 10dB, against 70Hz for the Ultimate Ears Megaboom 3. It is rated for 30 hours of battery against 20 for the Ultimate Ears Megaboom 3. At 1.4 lbs (657 g) it weighs noticeably less than the Ultimate Ears Megaboom 3 at 2 lbs (925 g). Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
The case for the Ultimate Ears Megaboom 3: IP67 rated, floats, and survives drops from up to 1 meter. The tradeoff: Not stereo, barely any bass.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality than the Ultimate Ears Megaboom 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

Ultimate Ears Megaboom 3: $191.99 Amazon $191.99 eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
Cons: Not stereo, barely any bass. 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 2018. Not technically a 360 speaker, only front and rear.
