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 2 ranks #93 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Charge 2’s replacement, the JBL Charge 6, is rated 4.2/5 at $119.95.
The Harman Kardon Luna is the better-sounding, tougher option. The sound is fairly balanced apart from the boosted bass. It is rated IP67 against IPX5 for the JBL Charge 2. It charges over USB-C rather than Micro USB. Watch for: Boosted bass, and less detailed than higher-ranked speakers.
Why pick the JBL Charge 2: Doubles as a 6000mAh power bank. ~10-12 hour battery life. It keeps a wired aux input, which the Harman Kardon Luna lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna. The tradeoff: Bass compression at higher volumes.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the JBL Charge 2 is discontinued.
