Perfectly adapted to Sennheiser PX100. It is a generic product whose lifespan will probably be less than that of the original but with 5 games for the price, you can see it coming. Listening side is less, the foam cutting much of the high frequencies that make the timbre of the instruments but if you listen only MP3 supersaturated, no matter ... A small note to the attention of those who fear to tear the delicate objects by putting them in place: first return the pad like a sock, keep the flat on the earpiece then gently fold the edges.
