Short answer: the Bogasing M4 on price, the JBL Charge 6 for a more neutral sound. The Charge 6 is flatter through the mids and treble than the Charge 5, which was quite rolled off up high, though it still has some boosted bass by default and costs $149.95. The M4 costs $45.99 and sounds most balanced in super bass mode, but it is a bit harsh and thin. The Bogasing M4 is discontinued; its replacement is the Bogasing M5.
Buy the JBL Charge 6. It is rated higher for sound quality; the Bogasing M4 is no longer sold new.
