the noise is less noticable while using shure e2c or koss porta pro and killing annoying with sennh cx300.It does not matter what kind of music i listen. No, it is impossible to fix that, my friend's same meizu m6 8gb model does not have this problem. I have tried all firmwares... I tried trick on meizu:started photo slideshow (2sec timeperslide) while playing music and turned off backlight. The noise disappears for every 2 seconds periodicaly.I also noticed that while pluging meizu to power charger, the noise also disappears. I drew a conslusion that it is hardware problem, maybe cpu or sound chip that produces noise. I am buying new meizu m6 soon
