Short answer: the Teufel Rockster Go 2. It ranks #93 of 179 medium speakers by sound quality, rated 3.2/5, at $99.99. The JBL Grip ranks #98, rated 3.1/5, at $69.95, $30.04 cheaper, a saving that is not big enough to make up the sound-quality gap.
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 supports AAC Bluetooth, which the JBL Grip lacks. It plays in stereo from a single unit, unlike the JBL Grip. The tradeoff: There is no companion app or 3.5 mm input.
The JBL Grip is the lighter choice. A small, fully waterproof speaker with app EQ, ambient lighting, Auracast linking and USB-C audio input. At 0.8 lbs (385 g) it weighs much less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). The catch: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
Buy the Teufel Rockster Go 2. It is rated higher for sound quality, and the $30.04 you would save on the JBL Grip does not close the gap.
