I just got the MZ-M100 and love it.. however besides the easily scratched case that I keep in the bag at all times lol... I have another problem with it I am usually using it on the fly and keep it in my pocket.. out of it I have the supplied remote and the microphone cable. After using for the past couple weeks I have noticed a scratchy sound on the left side while I'm moving around. I looked carefully at the remote's cable between the remote and the plug and noticed not one... not two... BUT three spots where the wires inside have twisted around each other and have started to chafe against each other and are exposing wires and shorting. I have fixed these spots and shrink tubed them ... but I fear that the problem will arise again. As a precaution I have refrained from using it unless its in a static environment. But I really like using it on the fly.
