Short answer: the Marshall Stockwell III. It ranks #84 of 120 large speakers by sound quality, rated 3.0/5, at $249.99; the B&O Beosound Level ranks #92, rated 2.8/5, and costs $2,250, so there is not much of a tradeoff to weigh.
The Marshall Stockwell III is the longer-running, lighter pick. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 16 for the B&O Beosound Level. At 2.9 lbs (1.3 kg) it weighs much less than the B&O Beosound Level at 7.3 lbs (3.3 kg). It supports AAC Bluetooth, which the B&O Beosound Level lacks. Watch for: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
What the B&O Beosound Level does well: A sculptural luxury speaker that works on battery or mains, mounts on a wall, and streams over Wi-Fi with upgradeable modules. Watch for: Not very deep bass, peaks in midrange.
Buy the Marshall Stockwell III. It is rated higher for sound quality than the B&O Beosound Level and costs less, so only choose the other one for a particular feature it does better.
