Short answer: the W-King D320. It ranks #49 of 177 medium speakers by sound quality, rated 3.6/5, at $52.92; the Bogasing M5 ranks #61, rated 3.5/5, and costs $52.99, which makes this an easy call rather than a real tradeoff.
The Bogasing M5 is the lighter choice. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. At 1.7 lbs (757 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Front/rear driver configuration.
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. Watch for: 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 Bogasing M5 and costs less, so only choose the other one for a particular feature it does better.
