Short answer: the Klipsch Austin. It ranks #15 of 62 small speakers by sound quality, rated 3.7/5, at $54.95. The Xiaomi Mi Portable Mini ranks #51, rated 2.6/5, at $21.99, $32.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Klipsch Austin is the better-sounding choice. A rugged waterproof mini speaker with dual passive radiators, a metal grille, and stereo pairing with a second unit. It links with other speakers (Broadcast Mode), which the Xiaomi Mi Portable Mini cannot. The tradeoff: Not as deep bass as higher ranked speakers.
The Xiaomi Mi Portable Mini is the lighter pick. A tiny, very cheap waterproof speaker with USB-C charging and stereo pairing with a second unit, easy to slip into any bag. At 0.4 lbs (185 g) it weighs much less than the Klipsch Austin at 0.9 lbs (397 g). Watch for: Not much bass, treble rolled off.
Buy the Klipsch Austin. It is rated higher for sound quality, and saving $32.96 with the Xiaomi Mi Portable Mini does not make up for the sound-quality gap.
