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 supports AAC Bluetooth, which the Soundcore 2 lacks. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The catch: There is no companion app or 3.5 mm input.
The Soundcore 2 is the longer-running, lighter pick. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 15 for the Teufel Rockster Go 2. At 0.7 lbs (318 g) it weighs much less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). It keeps a wired aux input, which the Teufel Rockster Go 2 lacks. The catch: Bass is specified only down to 70Hz, so the low end is limited.
