Short answer: the Ultimate Ears Megaboom 3. It ranks #86 of 142 medium speakers by sound quality at $191.99; the B&O Beosound Explore ranks #112 and costs $299, so there is little reason to consider the other one.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size. Watch for: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
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 Ultimate Ears Megaboom 3. It ranks higher for sound quality than the B&O Beosound Explore and costs less, so there is no real case for the other one.
Skip the B&O Beosound Explore if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
