Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality, rated 4.3/5, at $229.95; the B&O Beosound A1 3rd gen ranks #19, rated 4.1/5, and costs $399, so there is little reason to consider the other one.
The case for the Minirig 4: A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. It keeps a wired aux input, which the B&O Beosound A1 3rd gen lacks. The catch: Calls itself splash resistant and has no official water rating.
The B&O Beosound A1 3rd gen is the tougher option. A premium waterproof puck speaker with good sound, a long battery, and a battery you can swap, built to last. It is rated IP67 against Splash resistant for the Minirig 4. It supports aptX Adaptive Bluetooth, which the Minirig 4 lacks. The tradeoff: Distorts easier than the 2nd gen with deeper bass.
Buy the Minirig 4. It is rated higher for sound quality than the B&O Beosound A1 3rd gen and costs less, which makes it the one to get unless you need something the other one does better.
