A word of warning about the headband screws. I tried to tighten one of mine and it broke off because it had some sort of locking compound on it. Booth the bottom screw and the top adjuster were sealed and the threaded screws broke off flush. My SN# is HP000370, so I don't know if older units aren't sealed or newer units aren't sealed. If you try to turn the bottom screw with a flathead screwdriver and it doesn't want to loosen, I would leave it alone as it may be sealed like mine. Avantone is going to send me 2 complete new assemblies so I will be able to adjust them. One of my driver assemblies was tight but the other one was too loose, so I thought I could just tighten the screw to fix it, but no go on my phones.
