Short answer: the Harman Kardon Luna. It ranks #24 of 142 medium speakers by sound quality at $290.99; the B&O Beosound Explore ranks #112 and costs $299, so there is not much of a tradeoff to weigh.
What the Harman Kardon Luna offers: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment.
What the B&O Beosound Explore offers: IP67 rated with a rugged ‘seatbelt’ strap and carabiner hook. Real-world battery life around 20-24 hours. Distinctive anodized-aluminum design. Watch for: Huge lack of bass extension compared to competitors, overly hot ringing treble. Colored midrange. Just not great sounding overall.
Buy the Harman Kardon Luna. It ranks higher for sound quality than the B&O Beosound Explore and costs less, so the other one has nothing left to offer.
Skip the B&O Beosound Explore if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
There is a real battery-life gap here: the B&O Beosound Explore is rated for 27 hours, the Harman Kardon Luna only 12 hours.
