Short answer: the JBL Charge 5. It ranks #30 of 182 medium speakers by sound quality, rated 4.0/5, at $114.95. The Teufel Rockster Go 2 ranks #93, rated 3.2/5, at $99.99, $14.96 cheaper, which does not close the gap in sound quality.
The JBL Charge 5 is the better-sounding, longer-running pick. A rugged, fully waterproof speaker with punchy, warm sound and long battery life that also charges your phone. It is rated for 20 hours of battery against 15 for the Teufel Rockster Go 2. Watch for: Shouty upper mids.
The Teufel Rockster Go 2 is the lighter pick. A light, rugged waterproof speaker with very long battery life in eco mode, stereo pairing and a tripod mount. At 1.6 lbs (735 g) it weighs noticeably less than the JBL Charge 5 at 2.1 lbs (960 g). It plays in stereo from a single unit, unlike the JBL Charge 5. The tradeoff: There is no companion app or 3.5 mm input.
Buy the JBL Charge 5. It is rated higher for sound quality, and the $14.96 you would save on the Teufel Rockster Go 2 does not close the gap.
