Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the W-King D320 ranks #49, rated 3.6/5, and costs $52.92, so there is little reason to consider the other one.
The Bogasing G4 is the better-sounding, lighter pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. At 1.8 lbs (830 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: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
What the W-King D320 does well: An affordable waterproof travel speaker with loud, punchy bass, long battery life, an aux input, microSD playback and app EQ. It has an adjustable EQ, which the Bogasing G4 lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the Bogasing G4. It is rated higher for sound quality than the W-King D320 and costs less, which makes it the one to get unless you need something the other one does better.
