Replacement ear cups for my U70 headphones?
In a simple answer - No.
Manufacture of these ceased some years ago. Often, after many years the black vinyl cover disintigrates leaving the white cotton material showing underneath. There is very little that can be done other than attempt to replace them yourself using a soft leather-look material glued on to the white cloth, or carry on cleaning off the black "flakes" to leave an even white cloth cover.
Finding a pair now with perfect ear cups is virtually impossible, and most examples on the market have just had the original earpads "de-coated" by their patient owners!
