New listening comfort

In my Sennheiser PX100, the ear pads have dissolved. I had the headphones some time not in use, and he lay in a drawer; funny that the foam pads are simply disintegrate. I was pleased that various ear pads are available as a spare part. I had first mounted foam pad, which are suitable for different headphones and I then ordered these things from the fake leather.
The opening on the headphone side is quite narrow and I was concerned that the plastic will crack when I pull him through the headphones. With a little patience and sensitivity, it is well done and the pad sit well.
Very pleasant I feel the feeling when worn! Should I buy a new headset, I would replace immediately the original earpads to this spare part. Perhaps I order sometimes even a couple.
