my left ear cup has been making a weird noise and so has the right but it isnt as bad as the left. so i shined some light from the out side of the cup to the inside and i noticed a very skeletal like soonge material that the cup presses onto. does anyone have a problem with that sponge making a loud noise when ever you move your head around or press on the larger part of the cup? i really love these headphones but this noise is extremely irritating. i dont really want to ship these out and get a new pair and risk having the same problem assuming they would even ship out another pair. i was thinking of pulling the sponge out but i dont know what i could place in there with ease to replace it.
