Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Motion 100 is the better pick: it ranks #45 of 175 medium speakers by sound quality (rated 3.7/5), against #155 (rated 2.3/5) for the Harman Kardon Esquire 2. If you want one new, the EarFun Uboom L ranks #2 at $49.79.
The Soundcore Motion 100 is the better-sounding, longer-running pick. It is rated for 12 hours of battery against 8 for the Harman Kardon Esquire 2. It is rated IPX7 against IPX4 for the Harman Kardon Esquire 2. It supports LDAC Bluetooth, which the Harman Kardon Esquire 2 lacks. The tradeoff: Not very deep bass, slight distortion.
The Harman Kardon Esquire 2 is the lighter pick. 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 Soundcore Motion 100 at 1.3 lbs (575 g). It keeps a wired aux input, which the Soundcore Motion 100 lacks. The catch: Bass is weak, vocal and instrument separation is underwhelming and sounds tinny at high volume.
Buy the Soundcore Motion 100 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, start with the EarFun Uboom L instead.

Soundcore Motion 100: $47 Discontinued eBay
Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.
