Short answer: the Soundcore Boom 3i. It ranks #31 of 179 medium speakers by sound quality, rated 4.0/5, at $118.99. The Treblab HD77 ranks #100, rated 3.1/5, at $69.97, $49.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Boom 3i is the better-sounding, deeper-bass pick. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 66Hz for the Treblab HD77. It has an adjustable EQ, which the Treblab HD77 lacks. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
Why pick the Treblab HD77: An affordable speaker with an aux input, long battery life, a speakerphone mic and pairing with a second unit. It keeps a wired aux input, which the Soundcore Boom 3i lacks. 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.
