Short answer: the Turtlebox Gen 3, if you are buying new. The EarFun Uboom X ranks higher than it (#1 vs #105 of 113 boombox speakers, 4.7/5 vs 2.1/5) but is discontinued, so only consider it used; the Turtlebox Gen 3 is still sold new at $430.
What the Turtlebox Gen 3 gets right: A recognizable rugged design and a loud on-paper spec sheet. The catch: it ranks near the bottom of the boombox class here.
Buy the Turtlebox Gen 3 new; the EarFun Uboom X is no longer sold new, so it only makes sense as a used find.
