Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Charge 3 is the better pick: it ranks #91 of 175 medium speakers by sound quality (rated 3.2/5), against #155 (rated 2.3/5) for the Harman Kardon Esquire 2. If you want one new, the JBL Charge 6 replaces the JBL Charge 3 and is rated 4.2/5 at $119.95.
The JBL Charge 3 is the better-sounding, longer-running pick. Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. It is rated for 20 hours of battery against 8 for the Harman Kardon Esquire 2. It is rated IPX7 against IPX4 for the Harman Kardon Esquire 2. It plays in stereo from a single unit, unlike the Harman Kardon Esquire 2. Watch for: Less clarity than the JBL Flip 4.
The Harman Kardon Esquire 2 is the lighter option. Doubles as a conferencing speakerphone with a 4-mic array and noise/echo cancellation. At 0.8 lbs (350 g) it weighs much less than the JBL Charge 3 at 1.8 lbs (800 g). The tradeoff: Bass is weak, vocal and instrument separation is underwhelming and sounds tinny at high volume.
Buy the JBL Charge 3 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Charge 6, which replaces the JBL Charge 3.
