Short answer: the Xiaomi Mi Portable Mini wins on price and battery, though neither ranks well in its class. At $21.99 against $90 and ranked #44 of 54 versus #50 of 54, it matches the Neo’s water resistance with IP67 and runs a 10-hour battery. Pick the Neo only if you want its echo-cancelling mic for calls or its louder output. Both are rated below 3.0/5 among the 54 small speakers, and the Tribit Stormbox Micro 2, ranked #1 at $59.99, is a better place to start if sound quality matters.
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 is rated higher for sound quality; the Harman Kardon Neo is no longer sold new.
There is a real gap in water resistance: the Xiaomi Mi Portable Mini at IP67 (brief submersion) against the Harman Kardon Neo, which has no water resistance.
