Plantronics 780 plastic rubbing

[Eduard]

It's been a while since my last post, but I have come with a question.

Has anyone encountered the plastic rubbing sound you sometimes get with headsets?

This is my second pair of plantronics headphones, my previous ones were oldies from about 4 years ago. They generated this rubbing sound whenever I moved my head, the sound was not coming from the speakers at all, this was purely a structural sound. I just put that sound down as bad design and when they came to an unfortunate end (snapped by mistake) I purchased the 780's.
These ones were fine for about three months but now I am experiencing this rubbing sound again whenever I turn my head or look down. It's very distracting during study when I have my music quiet.

I was thinking of covering the joints of the headphones in graphite to act as a lubricant, though it may be a short lived solution as I expect that it would rub off fairly soon.

Does anyone have any solutions to this problem? Anyone experienced this before?

Is it a rubbing on the headset itself or more the cord is bumping against stuff and relaying the vibrations to you?

Hey,

Yeah I believe that it is the rubbing of the moving internal pieces and not the cord.
