Short answer: the Ultimate Ears Boom 4, if you are buying new. The JBL Charge 2 ranks higher than it (#90 vs #110 of 164 medium speakers, 3.2/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Boom 4 is still sold new at $149.99.
Buy the Ultimate Ears Boom 4 new; the JBL Charge 2 is no longer sold new, so it only makes sense as a used find.
