Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the JBL Charge 4 ranks #63 (rated 3.5/5) and is discontinued, so it is only an option used. The JBL Charge 4’s replacement, the JBL Charge 6, is rated 4.2/5 at $119.95.
The Harman Kardon Luna is the better-sounding choice. The sound is fairly balanced apart from the boosted bass. The catch: Boosted bass, and less detailed than higher-ranked speakers.
The JBL Charge 4 is the longer-running option. Doubles as a power bank for charging phones/tablets. It is rated for 20 hours of battery against 12 for the Harman Kardon Luna. It keeps a wired aux input, which the Harman Kardon Luna lacks. The catch: 1 Oval driver.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the JBL Charge 4 is discontinued.
