Short answer: the Xiaomi Mi Portable Mini. It ranks #37 of 47 small speakers by sound quality at $21.99; the Sony SRS-XB12 ranks #39 and costs $79, so there is not much of a tradeoff to weigh.
On the Xiaomi Mi Portable Mini side: 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. Set against that: Not much bass, treble rolled off.
What the Sony SRS-XB12 offers: Aux in. 16 hour battery life. IP67 rated, palm-sized with a detachable strap for hanging on a bag or belt. The tradeoff: Muddy, not much bass, peaky treble.
Buy the Xiaomi Mi Portable Mini. It ranks higher for sound quality than the Sony SRS-XB12 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 battery life is a priority, the Sony SRS-XB12 is rated for 16 hours versus 10 hours for the Xiaomi Mi Portable Mini.
