Short answer: the Harman Kardon Luna 2. It ranks #25 of 177 medium speakers by sound quality, rated 4.1/5, at $199.95; the B&O Beosound Explore ranks #142, rated 2.5/5, and costs $294.99, so there is not much of a tradeoff to weigh.
The Harman Kardon Luna 2 is the better-sounding option. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The B&O Beosound Explore is the longer-running pick. A rugged waterproof speaker with an anodized aluminum design, a strap and carabiner, and a long real world battery. It is rated for 27 hours of battery against 12 for the Harman Kardon Luna 2. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. Watch for: Huge lack of bass extension compared to competitors, overly hot ringing treble.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality than the B&O Beosound Explore and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
