Short answer: the Soundcore Boom 3i. It ranks #29 of 144 medium speakers by sound quality, rated 4.0/5, at $118.99. The Treblab HD77 ranks #82, rated 3.1/5, at $69.97, $49.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Soundcore Boom 3i: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. The catch: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Why pick the Treblab HD77: Supports TWS pairing with a second HD77 for wider stereo sound. Watch for: Lacking quite a bit of bass compared to higher ranked speakers.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and saving $49.02 with the Treblab HD77 does not make up for the sound-quality gap.
