Query: Movement Noice

I bought The JVC Headphones (Black) to record my music and they sound great. However, when the parts move, I hear noice perhaps caused by headphone moving in the bracket it pivots in. Either they need oil or some type of rubber washer to prevent this. The manufacturer need to take a look at this. Could be I have a defective one. I don't know. The price is right.
