Thanks for the answer. Also, it seems that the HZP26 is smaller than the HZP15. I mean, the HZP26 doesn't seem to take all the ears. Is it true ?

Hello guys,   I have a pc350 SE, and my earpads are pretty worn out.... So I need to replace it. I know that I can find the original earpads HZP15 in Sennheiser website. But I want to switch from HZP15 to HZP26. The HZP26 are for pc360D and pc360. So i'm wondering if the hzp26 are compatible...
