Short answer: the Ultimate Ears Epicboom for battery life and a USB-C portable design, though neither ranks well in its class. It runs 17 hours on USB-C, the first UE portable with USB-C, though its bass is not very deep for the size. The B&O Beosound Level offers a premium Scandinavian design with an elegant domestic sculpture aesthetic, but it also has not very deep bass and peaks in the midrange. Both are rated below 3.0/5 among the 93 large speakers, and the JBL Xtreme 5, ranked #2 at $399.95, is a better place to start if sound quality matters.
Buy the Ultimate Ears Epicboom. It is rated higher for sound quality than the B&O Beosound Level and costs less, so only choose the other one for a particular feature it does better.
Water resistance is not close: the Ultimate Ears Epicboom is rated at IPX7 (brief submersion), well ahead of the B&O Beosound Level at IP54 (splashing).
