Short answer: the JBL Flip 6. It ranks #13 of 182 medium speakers by sound quality, rated 4.2/5, at $114.95. The Teufel Rockster Go 2 ranks #93, rated 3.2/5, at $99.99, $14.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Flip 6 is the better-sounding, lighter choice. A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. At 1.2 lbs (544 g) it weighs noticeably less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). Watch for: Some slight upper mids emphasis.
Why pick 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 plays in stereo from a single unit, unlike the JBL Flip 6. Watch for: There is no companion app or 3.5 mm input.
Buy the JBL Flip 6. It is rated higher for sound quality, and saving $14.96 with the Teufel Rockster Go 2 does not make up for the sound-quality gap.
