Nature Replacement Ear Pads Pad Cushion for Panasonic RPHC500 RPHC300 RP HC500 HC300 Headphones

Pros: Very fast, Fit My Panasonic RPHC500 Headphones,safe delivery from China. Comfortable, snug fit. Con: I've had previous, bad experience with the covering on the ear pads with Sony headphones. The covering vinyl dries out fast, splitting and breaking into little pieces. Cleaning the surface often didn't help. I would suggest coating the pads EVERY night with Armor All.

These do not work for the RP-HC500 Panasonic Noise Canceling headphones. Felt great, put them on, fit perfect, but they were incompatible with the headphones. The old pads made no feedback noise, the new pads cause horrible feedback. These headphones use microphones to produce cancellation, and they were in some kind of feedback loop from the materials used.

The cups are very well made and look great on the headset after replacement.In my specific case on my Philips noise cancelling headset though after replacement this high pitched noise started coming out in certain position of the headset when the NC is on. Taking them off about 1 inch away from my head it would start making the noise. Hard to say what caused it, most likely the position of this thin sheet just behind the cup, but hard to say.

These were just what I was looking for. They fit well and were in-expensive. I just wish I could find a replacement headband cover for the headphones as well.

These are not as thick as the original Audio Technica pads they replaced, but they are sufficiently comfortable and otherwise work just as well.
