Short answer: the Marshall Stockwell III. It ranks #59 of 82 large speakers by sound quality, rated 3.0/5, at $249.99; the B&O Beosound Level ranks #65, rated 2.8/5, and costs $2,250, so there is not much of a tradeoff to weigh.
The case for the Marshall Stockwell III: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. 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: Premium Scandinavian design with elegant domestic sculpture aesthetic. 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.
If battery life is a priority, the Marshall Stockwell III is rated for 40 hours versus 16 hours for the B&O Beosound Level.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
Older model: the Marshall Stockwell II (rated 4.5/5).
Pros: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. Doubles as a USB-C power bank. IP55 dust/water resistance. App includes parametric EQ, a Soundstage widening control, and wall/corner placement compensation. Endless-rotation control knobs.
Cons: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then. Bass tends to sound resonant and boomy, with reported frequency cancellation and phase issues on complex material that EQ doesn’t fully resolve. Oluv’s A/B testing against the outgoing Stockwell II finds the default tuning muffled and muddy enough to prefer the seven-year-old original out of the box, and output loses dynamics and bass while turning harsh well below maximum volume. No aptX support.
