Short answer: the Motion 300 is the much more flexible and capable speaker, while the discontinued Bogasing M4 only makes sense as a very inexpensive simple option. Soundcore adds app EQ, LDAC, orientation-specific tuning, more output and slightly deeper bass. Its stock treble is far too rolled off, so the advantage depends on applying an EQ. Bogasing’s 24-hour claimed battery and aux input are useful, but it has no app or tone controls. The Bogasing M4 is discontinued; its replacement is the Bogasing M5.
Buy the Bogasing M4 only if you find remaining stock cheaply and value long battery life plus an aux input over sound tuning controls.
Buy the Soundcore Motion 300 if you will use the app EQ and want deeper bass, greater output and a more versatile portable speaker.
There is a real battery-life gap here: the Bogasing M4 is rated for 24 hours, the Soundcore Motion 300 only 13 hours.
