Short answer: the Minirig 4. It ranks #6 of 142 medium speakers by sound quality at $229.95; the B&O Beosound A1 3rd gen ranks #18 and costs $381.52, so there is little reason to consider the other one.
What the Minirig 4 offers: Modular, can easily attach a subwoofer. Finally USB-C charging. Dynamically changes sound based on forward facing or upward facing orientation Watch for: Calls itself splash resistant and has no official water rating. App is buggy. A bit expensive. Has reliability issues more often than any other speaker
What the B&O Beosound A1 3rd gen offers: Longer battery than the 2nd gen (~24 hours at sensible volumes). IP67 rated with a serviceable, replaceable battery - the first Bluetooth speaker with Cradle to Cradle certification. Multipoint connectivity and aptX Adaptive. Watch for: Distorts easier than the 2nd gen with deeper bass. Dipped area in the upper mids. Not as deep of bass as the 2nd gen
Buy the Minirig 4. It ranks higher for sound quality than the B&O Beosound A1 3rd gen and costs less, so the other one has nothing left to offer.
