Short answer: the Soundcore 3. It ranks #62 of 157 medium speakers by sound quality, rated 3.4/5, at $59.99; the Treblab HD77 ranks #91, rated 3.1/5, and costs $69.97, which makes this an easy call rather than a real tradeoff.
The Soundcore 3 is the lighter choice. Identical in acoustic design and performance to the retailer variant Soundcore Select 2. At 0.8 lbs (372 g) it weighs much less than the Treblab HD77 at 1.4 lbs (637 g). It has an adjustable EQ, which the Treblab HD77 lacks. It plays in stereo from a single unit, unlike the Treblab HD77.
Why pick the Treblab HD77: Supports TWS pairing with a second HD77 for wider stereo sound. It keeps a wired aux input, which the Soundcore 3 lacks. The tradeoff: Lacking quite a bit of bass compared to higher ranked speakers.
Buy the Soundcore 3. It is rated higher for sound quality than the Treblab HD77 and costs less, which makes it the one to get unless you need something the other one does better.
