I wanted to share my imitation leather plastic ear pads from Sennheiser RS170 against velor ear pads, because I feel that as much more pleasant. However, I did not order this earpads offered here - and rate them anyway! There are two reasons for this: First you can read here "for mounting the plastic rings of the old original ear pads are needed." The original ear pads Sennheiser, however, everything is already complete. I do not throw the old pad off, too, but they depositories as a substitute. They should like to keep their bayonet ring yet. Secondly, the original pads are simply cheaper! I paid some time ago for 14.50 EUR - with the certainty that the original spare part also fits perfectly. The cushion of this offer so I have not had on the ears and can not say anything about how they feel.
