Something happened to my nausnikas (with that skin or whatever it is) and I would like to replace them. My headphones are Sony MDR zx610ap. The nails have a diameter of 70 mm. I looked at the internet where the nausniks looked just like mine. But the dimensions are not written anywhere. I wonder if the dimensions don't differ or where I can get exactly the same ones to sit there. Possibly. If they exchanged them for me if I had them fixed
