However,
if the cord rubs against anything ever so slightly (my shirt, my desk, my computer, a thick patch of oxygen), I can hear it.
if the headphones 'flex' at all ever so slightly (by touching it, turning my head 2 degrees, breathing wrong), I can hear it.
if I touch the headphones anywhere ever so slightly (the ear pieces, the bridge, the padding), I can hear it.
None of this bothered me at first, then it became annoying. Now, it actually makes me cringe every time. All 3 of these things happen, mostly simultaneously, as frequently as every other second, and no less often than every 30 seconds. It sounds like a mixture of someone gritting their teeth, sand blasting a cat, and blaring dubstep directly in my ears at the same time.
What the hell can I do to fix this?
