Not much to say. They came in a genuine plastic package and made the headphones feel like new. A bit of a pain to install though. I recommend reading the manual as there are good tips in there to make them easier to fit on.
Don't waste your money on cheap parts, specially if the headphones aren't cheap themselves.
After trying twice with 10$ earpads and not being satisfied with them, I decided to buy these. Im very happy with this decision as they proved to be extremely high quality and they came very fast to Brazil too.
