Short answer: the Tribit Xsound Go. Both are rated 3.1/5 for sound quality (#101 and #100 of 179 medium speakers), and the Tribit Xsound Go costs $34.99 against $69.97 for the Treblab HD77, and with sound quality even, the cheaper one is the better buy.
The Treblab HD77 is the deeper-bass choice. An affordable speaker with an aux input, long battery life, a speakerphone mic and pairing with a second unit. Its bass reaches about 66Hz before falling 10dB, against 83Hz for the Tribit Xsound Go. The catch: Lacking quite a bit of bass compared to higher ranked speakers.
The Tribit Xsound Go is the lighter pick. A very light, inexpensive waterproof stereo speaker with long battery life for travel and casual listening. At 0.8 lbs (380 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. The tradeoff: Lacking quite a bit of bass compared to bigger speakers.
Buy the Tribit Xsound Go. Both are rated the same for sound quality, and it costs $34.98 less than the Treblab HD77.
