Short answer: the Xiaomi Mi Portable Mini is the better buy, though neither ranks well in its class. It ranks #40 of 50 against #45 of 50 for the Harman Kardon Esquire Mini 2, costs $21.99 to $100, and adds IP67 waterproofing, USB-C charging and a 10-hour battery. The Esquire’s edge is doubling as a speakerphone and USB power bank, but both lack bass. Both are rated below 3.0/5 among the 50 small speakers, and the Tribit Stormbox Micro 2, ranked #1 at $59.99, is a better place to start if sound quality matters.
Buy the Xiaomi Mi Portable Mini. It is rated higher for sound quality; the Harman Kardon Esquire Mini 2 is no longer sold new.
Water resistance is not close: the Xiaomi Mi Portable Mini is rated at IP67 (brief submersion), well ahead of the Harman Kardon Esquire Mini 2 at no water resistance.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
