Short answer: the Harman Kardon Luna if sound quality matters most, the Harman Kardon Esquire 2 if price matters most. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Harman Kardon Esquire 2 ranks #120 at $200, $90.99 cheaper.
What the Harman Kardon Luna offers: Pretty balanced sound besides the boosted bass. Watch for: Not stereo. Boosted bass, not as detailed as higher ranked speakers
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 Harman Kardon Luna if sound quality is the priority over the price, or the Harman Kardon Esquire 2 if the price is the priority over sound quality.
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.
If water resistance matters to you, the Harman Kardon Luna at IP67 (brief submersion) holds up far better than the Harman Kardon Esquire 2 at IPX4 (splashing).
