i purchased there earpads for my sony headphones as the original ones were deteriating fast. I'd had them for probably close to 20 years.
They arrived quickly and, after some major swearing they are on and are very comfortable.
The reason for the swearing was problems putting them on as they are very tight and I don't have enough fingers to hold them in place arond the headphones.
Eventually I used some plastic pieces to wedge the sections I had in in place so I could move on to the next bit, eventually getting them on and positioned correctly.
As I said, they are really comfortable and I am looking forward to many more years of listening with them.
