Short answer: the Doss Soundbox for value, the Ultimate Ears Megaboom 4 for durability, though neither ranks well in its class. The Soundbox costs $79 against $200 and brings IPX4 splashproofing, 12-hour battery life, MicroSD, dual full-range drivers and Bluetooth 4.0, but it has barely any bass. The Megaboom 4 is IP67 rated, floats and uses USB-C charging, though it distorts a lot at higher volumes. Both are rated below 3.0/5 among the 151 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Buy the Ultimate Ears Megaboom 4 new; the Doss Soundbox is no longer sold new, so it only makes sense as a used find.
