Short answer: the Ultimate Ears Wonderboom 2. It ranks #89 of 142 medium speakers by sound quality at $80; the B&O Beosound Explore ranks #112 and costs $299, which makes this an easy call rather than a real tradeoff.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. 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 2019. 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 Wonderboom 2. 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 Ultimate Ears Wonderboom 2 only 12 hours.
