Short answer: the W-King D320. It ranks #49 of 179 medium speakers by sound quality, rated 3.6/5, at $52.92; the Treblab HD77 ranks #100, rated 3.1/5, and costs $69.97, so there is not much of a tradeoff to weigh.
The W-King D320 is the better-sounding choice. 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 Treblab HD77 lacks. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Treblab HD77 is the lighter pick. An affordable speaker with an aux input, long battery life, a speakerphone mic and pairing with a second unit. At 1.4 lbs (637 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Lacking quite a bit of bass compared to higher ranked speakers.
Buy the W-King D320. It is rated higher for sound quality than the Treblab HD77 and costs less, so only choose the other one for a particular feature it does better.
