Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Mini 3 is the better pick: it ranks #9 of 62 small speakers by sound quality (rated 4.1/5), against #58 (rated 2.3/5) for the Harman Kardon Neo. If you want one new, the Tribit Stormbox Micro 2 ranks #1 at $39.99.
The Soundcore Mini 3 is the better-sounding, deeper-bass option. Deeper bass than most speakers its size. Its bass reaches about 58Hz before falling 10dB, against 105Hz for the Harman Kardon Neo. It is rated for 15 hours of battery against 10 for the Harman Kardon Neo. It is rated IPX7, while the Harman Kardon Neo has no water resistance. The catch: Rolled off highs.
Why pick the Harman Kardon Neo: Harman Kardon Neo uses 1.6” (41mm) full-range driver. The tradeoff: Bass is limited by its 105Hz specification.
Buy the Soundcore Mini 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, start with the Tribit Stormbox Micro 2 instead.
