Short answer: the B&O Beosound A1 3rd gen for better sound quality, the W-King D320 for the lower price. The B&O Beosound A1 3rd gen ranks #19 of 177 medium speakers, rated 4.1/5, at $399. The W-King D320 ranks #49, rated 3.6/5, at $52.92, $346.08 cheaper.
The B&O Beosound A1 3rd gen is the better-sounding, lighter choice. A premium waterproof puck speaker with good sound, a long battery, and a battery you can swap, built to last. At 1.2 lbs (558 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Distorts easier than the 2nd gen with deeper bass.
Why pick the W-King D320: 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 A1 3rd gen lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the B&O Beosound A1 3rd gen if sound quality is the priority over the price, or the W-King D320 if the price is the priority over sound quality.
