Short answer: the KEF Muo gen2 for balance, with both short on deep bass. KEF seemed to have fixed the rolled off treble and overall balance on the Muo gen2, though it is lacking deeper bass, and at $249.99 it undercuts the Beosound Explore’s $299. The Explore is IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook but has a huge lack of bass extension and overly hot ringing treble.
What the B&O Beosound Explore gets right: IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. The tradeoff: Huge lack of bass extension compared to competitors, overly hot ringing treble.
On the KEF Muo gen2 side: KEF seemed to have fixed the rolled off treble and overall balance. The catch: Lacking deeper bass.
Buy the KEF Muo gen2. It is rated higher for sound quality than the B&O Beosound Explore and costs less, so there is no real case for the other one.

KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
