Short answer: the W-King D320. It ranks #49 of 177 medium speakers by sound quality, rated 3.6/5, at $52.92; 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 B&O Beosound Explore is the lighter option. A rugged waterproof speaker with an anodized aluminum design, a strap and carabiner, and a long real world battery. At 1.4 lbs (631 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). It plays in stereo from a single unit, unlike the W-King D320. The catch: Huge lack of bass extension compared to competitors, overly hot ringing treble.
The W-King D320 is the better-sounding option. An affordable waterproof travel speaker with loud, punchy bass, long battery life, an aux input, microSD playback and app EQ. It keeps a wired aux input, which the B&O Beosound Explore lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the W-King D320. It is rated higher for sound quality than the B&O Beosound Explore and costs less, which makes it the one to get unless you need something the other one does better.
