Short answer: the Bogasing M4 on price, the JBL Charge 5 for the power-bank feature. At $45.99 against the Charge 5’s $114.95, the M4 sounds most balanced in super bass mode but is a bit harsh and thin. The JBL doubles as a power bank over USB-A out for charging your phone, though it is not stereo. The Bogasing M4 is discontinued; its replacement is the Bogasing M5.
Buy the JBL Charge 5 new; the Bogasing M4 is no longer sold new, so it only makes sense as a used find.
