Short answer: the Soundcore 2, if you are buying new. The Bogasing M4 ranks higher than it (#28 vs #103 of 164 medium speakers, 4.0/5 vs 3.0/5) but is discontinued, so only consider it used; the Soundcore 2 is still sold new at $29.99.
The Bogasing M4 is the better-sounding option. Super Bass mode gives the most balanced sound. It charges over USB-C rather than Micro USB. Watch for: It sounds a bit harsh and thin.
The Soundcore 2 is the lighter option. At 0.7 lbs (318 g) it weighs much less than the Bogasing M4 at 1.6 lbs (731 g).
Buy the Soundcore 2 if you want one new; the Bogasing M4 is discontinued, so only look for it used.
