Short answer: the Teufel Rockster Go 2. It ranks #93 of 182 medium speakers by sound quality, rated 3.2/5, at $99.99. The Treblab HD77 ranks #100, rated 3.1/5, at $69.97, $30.02 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Teufel Rockster Go 2: A light, rugged waterproof speaker with very long battery life in eco mode, stereo pairing and a tripod mount. It has an adjustable EQ, which the Treblab HD77 lacks. It plays in stereo from a single unit, unlike the Treblab HD77. The catch: There is no companion app or 3.5 mm input.
The Treblab HD77 is the longer-running pick. An affordable speaker with an aux input, long battery life, a speakerphone mic and pairing with a second unit. It is rated for 20 hours of battery against 15 for the Teufel Rockster Go 2. It keeps a wired aux input, which the Teufel Rockster Go 2 lacks. The catch: Lacking quite a bit of bass compared to higher ranked speakers.
Buy the Teufel Rockster Go 2. It is rated higher for sound quality, and the $30.02 saving on the Treblab HD77 is not enough to make up the difference.
