Short answer: the JBL Charge Essential, if you are buying new. The Bogasing M4 ranks higher than it (#28 vs #89 of 164 medium speakers, 4.0/5 vs 3.2/5) but is discontinued, so only consider it used; the JBL Charge Essential is still sold new at $73.99.
The Bogasing M4 is the better-sounding choice. Super Bass mode gives the most balanced sound. It keeps a wired aux input, which the JBL Charge Essential lacks. It plays in stereo from a single unit, unlike the JBL Charge Essential. It charges over USB-C rather than Micro USB. The catch: It sounds a bit harsh and thin.
Why pick the JBL Charge Essential: Doubles as a power bank. The catch: Less clarity than the Flip 4, highs rolled off.
Buy the JBL Charge Essential new; the Bogasing M4 is no longer sold new, so it only makes sense as a used find.
