One of the hinge of my M500 is getting a bit loose, I rotated the ear piece so I can see the screws. They look like those tiny hexagonal screws, I have no idea where I can get the screw driver for those.
Anyone ran into the same problem?
My ear just got electric shocked by my M100. I was listening to music and then heard a buzz sound from the left driver and there was a little electric shock on my left ear. This may be related to the hissing sound i talked about. Anyone had this issue?
