Short answer: the Miatone Boompro. It ranks #15 of 150 medium speakers by sound quality, rated 4.2/5, at $35.99; the JBL Charge 4 ranks #56, rated 3.5/5, and costs $94.99, so there is little reason to consider the other one.
Why pick the Miatone Boompro: Exactly the same as the Wisetiger P3 below. The tradeoff: Slightly less bass extension than higher ranked speakers.
What the JBL Charge 4 does well: Doubles as a power bank for charging phones/tablets. The catch: Not stereo.
One note: the JBL Charge 4 is no longer sold new, but at #56 of 150 medium speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the Miatone Boompro. It is rated higher for sound quality than the JBL Charge 4 and costs less, so only choose the other one for a particular feature it does better.
