If you use a headset frequently, it's important to change the ear cushion periodically. Ear cushions absorb a lot of sweat, dirt and makeup and can breed bacteria if not cleaned or replaced as necessary. This can lead to bacterial ear infections in extreme cases. Repeated and frequent use can also cause foam ear cushion to deteriorate and break into pieces over time.

Found these pads available at the url below, they are not original but they are still exceptional quality.

Here you will find something.

I had the same problem, until I realized that the headphones have 2 batteries. I was only replacing one.

You might want to take a look at my Tip on headphones, right at the bottom of it. Just click my user name to find it.
