Short answer: the Tribit Stormbox Blast 2, if you are buying new. The EarFun Uboom X ranks higher than it (#1 vs #31 of 113 boombox speakers, 4.7/5 vs 3.8/5) but is discontinued, so only consider it used; the Tribit Stormbox Blast 2 is still sold new at $279.99.
Buy the Tribit Stormbox Blast 2 new; the EarFun Uboom X is no longer sold new, so it only makes sense as a used find.
