Short answer: the DBSONO X-Blast F37, if you are buying new. The JBL Charge 3 ranks higher than it (#77 vs #102 of 150 medium speakers, 3.2/5 vs 2.8/5) but is discontinued, so only consider it used; the DBSONO X-Blast F37 is still sold new at $69.99.
The case for the JBL Charge 3: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The tradeoff: Less clarity than the Flip 4.
What the DBSONO X-Blast F37 does well: 25W woofer + 10W tweeter + rear passive radiator. The catch: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
Buy the DBSONO X-Blast F37 new; the JBL Charge 3 is no longer sold new, so it only makes sense as a used find.
