Short answer: the Tribit Stormbox Flow. It ranks #49 of 136 medium speakers by sound quality at $60; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is little reason to consider the other one.
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 Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the Tribit Stormbox Flow. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
There is a real battery-life gap here: the Tribit Stormbox Flow is rated for 30 hours, the Ultimate Ears Megaboom 4 only 20 hours.
