Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Mini 3 Pro is the better pick: it ranks #8 of 62 small speakers by sound quality (rated 4.1/5), against #57 (rated 2.4/5) for the Harman Kardon Esquire Mini 2. If you want one new, the Tribit Stormbox Micro 2 ranks #1 at $39.99.
The Soundcore Mini 3 Pro is the better-sounding, deeper-bass choice. Lights on top. Its bass reaches about 58Hz before falling 10dB, against 120Hz for the Harman Kardon Esquire Mini 2. It is rated for 15 hours of battery against 10 for the Harman Kardon Esquire Mini 2. It is rated IPX7, while the Harman Kardon Esquire Mini 2 has no water resistance. The catch: Rolled off highs.
The case for the Harman Kardon Esquire Mini 2: Doubles as a hands-free speakerphone and USB power bank. It keeps a wired aux input, which the Soundcore Mini 3 Pro lacks. The tradeoff: Huge lack of bass.
Buy the Soundcore Mini 3 Pro 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 Tribit Stormbox Micro 2 instead.

The Two Speakers In Full
Soundcore Mini 3 Pro: $30 Discontinued eBay
Pros: Lights on top. Deeper bass than most other speakers in the size. Measured bass extension of 58Hz (-10dB).
Cons: Rolled off highs. Real-world battery life falls well short of the 15-hour claim at higher volumes. Buttons are hard to see (black print on black housing) and it won’t multipoint to two phones at once. Discontinued and no longer sold new.
