Short answer: the B&O Beosound A1 2nd gen. It ranks #11 of 164 medium speakers by sound quality (rated 4.3/5) at $395 and is still sold new; the Xiaomi Mi Portable ranks #75 (rated 3.4/5) and is discontinued, so it is only an option used.
The B&O Beosound A1 2nd gen is the better-sounding, longer-running option. It is rated for 18 hours of battery against 13 for the Xiaomi Mi Portable. It supports aptX Adaptive Bluetooth, which the Xiaomi Mi Portable lacks.
The Xiaomi Mi Portable is the lighter option. Good battery life for a 16W speaker: around 12 hours at moderate volume. At 0.8 lbs (373 g) it weighs noticeably less than the B&O Beosound A1 2nd gen at 1.2 lbs (558 g). It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. It plays in stereo from a single unit, unlike the B&O Beosound A1 2nd gen. The tradeoff: A bit of a sharp treble.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality, and the Xiaomi Mi Portable is discontinued, so it is only available used.
