Short answer: the Xiaomi Mi Portable Mini. It ranks #37 of 47 small speakers by sound quality at $21.99; the Harman Kardon Neo ranks #43 and costs $90, so there is not much of a tradeoff to weigh.
What the Xiaomi Mi Portable Mini gets right: IP67 waterproof, TWS stereo pairing, 10-hour battery life, Bluetooth 5.0, compact 185g design, bass boost equalizer, dual drivers with passive radiator, built-in microphone, USB-C charging, affordable price. Watch for: Not much bass, treble rolled off.
The case for the Harman Kardon Neo: IPX7 waterproof. Elegant matte-metal design with an attachment loop. Echo-cancelling mic for calls; goes louder than its size suggests. The tradeoff: Huge lack of bass.
Buy the Xiaomi Mi Portable Mini. It ranks higher for sound quality than the Harman Kardon Neo and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 47 small speakers instead.
If water resistance matters to you, the Xiaomi Mi Portable Mini at IP67 (brief submersion) holds up far better than the Harman Kardon Neo at no water resistance.
