Short answer: the Soundcore Mini 3. It ranks #9 of 47 small speakers by sound quality at $41; the Harman Kardon Neo ranks #43 and costs $90, so there is little reason to consider the other one.
What the Soundcore Mini 3 offers: Deeper bass than most other speakers in the size. Watch for: Rolled off highs
What the Harman Kardon Neo offers: IPX7 waterproof. Elegant matte-metal design with an attachment loop. Echo-cancelling mic for calls; goes louder than its size suggests. Watch for: Huge lack of bass.
Buy the Soundcore Mini 3. It ranks higher for sound quality than the Harman Kardon Neo and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the Harman Kardon Neo. It ranks near the bottom of the 47 small speakers, so look higher up the list instead.
Battery life favors the Soundcore Mini 3: rated for 15 hours against 10 hours for the Harman Kardon Neo.
Water resistance is not close: the Soundcore Mini 3 is rated at IPX7 (brief submersion), well ahead of the Harman Kardon Neo at no water resistance.
