Short answer: the Soundcore Boom Go 3i. It ranks #2 of 47 small speakers by sound quality at $79.99; the Harman Kardon Neo ranks #43 and costs $90, so there is not much of a tradeoff to weigh.
What the Soundcore Boom Go 3i offers: IP68 rated (full submersion + dustproof). ~24 hour battery life. RGB light strip syncs to the music. USB-C port doubles as a power bank for charging your phone. Watch for: Sounds a bit piercing and metallic. Bass knocks a little bit. Peak at 10khz
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 Boom Go 3i. It ranks higher for sound quality than the Harman Kardon Neo and costs less, so the other one has nothing left to offer.
The Harman Kardon Neo is not a sound-quality pick. It sits near the bottom of the 47 small speakers; there are better options higher up.
There is a real battery-life gap here: the Soundcore Boom Go 3i is rated for 24 hours, the Harman Kardon Neo only 10 hours.
If water resistance matters to you, the Soundcore Boom Go 3i at IP68 (extended submersion) holds up far better than the Harman Kardon Neo at no water resistance.
