Short answer: the W-King D320. It ranks #44 of 136 medium speakers by sound quality at $69.99; the Harman Kardon Esquire 2 ranks #120 and costs $200, which makes this an easy call rather than a real tradeoff.
What the W-King D320 offers: 40W output power, IP67 waterproof, 24-hour battery life, customizable EQ app with 6 preset modes, Bluetooth 5.3, AUX and MicroSD support, dual tweeters with passive radiators, USB-C charging Watch for: Not stereo. Warm tuning. Lacking some detail. Rolled off treble
What the Harman Kardon Esquire 2 offers: Doubles as a conferencing speakerphone with a 4-mic array and noise/echo cancellation. Flat, compact design packs easily. USB charge-out for topping off a phone. Watch for: Bass is weak, vocal and instrument separation is underwhelming and sounds tinny at high volume
Buy the W-King D320. It ranks higher for sound quality than the Harman Kardon Esquire 2 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Harman Kardon Esquire 2. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
Battery life favors the W-King D320: rated for 24 hours against 8 hours for the Harman Kardon Esquire 2.
If water resistance matters to you, the W-King D320 at IP67 (brief submersion) holds up far better than the Harman Kardon Esquire 2 at IPX4 (splashing).
