Short answer: the Bose Soundlink Micro 2 if sound quality matters most, the Xiaomi Mi Portable Mini if price matters most. The Bose Soundlink Micro 2 ranks #18 of 62 small speakers, rated 3.6/5, at $129. The Xiaomi Mi Portable Mini ranks #51, rated 2.6/5, at $21.99, $107.01 cheaper.
The Bose Soundlink Micro 2 is the better-sounding pick. A waterproof mini speaker with a fabric strap for bags and bikes and USB-C charging. It supports aptX Bluetooth, which the Xiaomi Mi Portable Mini lacks. It links with other speakers (Bose Party mode), which the Xiaomi Mi Portable Mini cannot. It has an adjustable EQ, which the Xiaomi Mi Portable Mini lacks. The catch: Lack of clarity.
The Xiaomi Mi Portable Mini is the lighter option. 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 Bose Soundlink Micro 2 at 0.7 lbs (329 g). The catch: Not much bass, treble rolled off.
Buy the Bose Soundlink Micro 2 when sound quality outweighs the price for you, and the Xiaomi Mi Portable Mini when the price outweighs sound quality instead.
