Short answer: the Minirig 4. It ranks #7 of 164 medium speakers by sound quality (rated 4.3/5) at $229.95 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 Minirig 4 is the better-sounding, longer-running pick. Modular, can easily attach a subwoofer. It is rated for 30 hours of battery against 13 for the Xiaomi Mi Portable. It supports AAC Bluetooth, which the Xiaomi Mi Portable lacks. The catch: Calls itself splash resistant and has no official water rating.
The Xiaomi Mi Portable is the lighter, tougher pick. 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 Minirig 4 at 1.2 lbs (550 g). It is rated IPX7 against Splash resistant for the Minirig 4. It plays in stereo from a single unit, unlike the Minirig 4. The tradeoff: A bit of a sharp treble.
Buy the Minirig 4. It is rated higher for sound quality, and the Xiaomi Mi Portable is discontinued, so it is only available used.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
