Short answer: the Soundcore Motion 300. It ranks #3 of 182 medium speakers by sound quality, rated 4.5/5, at $79.99; the Teufel Rockster Go 2 ranks #93, rated 3.2/5, and costs $99.99, so there is little reason to consider the other one.
The Soundcore Motion 300 is the better-sounding option. A compact stereo speaker with deep bass for its size, hi res Bluetooth and a custom EQ for each position, standing or lying down. It supports LDAC Bluetooth, which the Teufel Rockster Go 2 lacks. The catch: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
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. The catch: There is no companion app or 3.5 mm input.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Teufel Rockster Go 2 and costs less, which makes it the one to get unless you need something the other one does better.
