Short answer: both are discontinued, so this only matters if you are buying used. Used, the Bogasing M4 is the better pick: it ranks #28 of 164 medium speakers by sound quality (rated 4.0/5), against #88 (rated 3.2/5) for the JBL Charge 3. If you want one new, the Earfun Uboom L ranks #2 at $49.79.
The Bogasing M4 is the better-sounding, deeper-bass choice. Super Bass mode gives the most balanced sound. Its bass reaches about 54Hz before falling 10dB, against 63Hz for the JBL Charge 3. It charges over USB-C rather than Micro USB. The catch: It sounds a bit harsh and thin.
What the JBL Charge 3 does well: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. Watch for: Less clarity than the Flip 4.
Buy the Bogasing M4 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
