Audio123 Upgrade Foam ear pad cushion for KOSS porta pro portapro stereo PP 50mm pads

It'd love to give a good rating to these pads. They're well made and look to be pretty durable, BUT... they do not fit Koss Porta Pros!I spent the best part of an hour trying to get them over the cones, but the aperture where you're supposed to slide the cones in is just far too small, and there is no give in them. In their end there have just gone straight in the bin I'm sorry to say.Well made, but not fit for purpose.

Absolutely brilliant upgrade to the original - I recommend them unreservedly, with a superb tight fit, as you would want. Requires patience to fit, but the excellent fit is the whole point.

Fit ok but don't feel nice and have adverse impact on sound quality. I don't use them.

Great item. The default ear pads disintegrate after a few wears. These are much more sturdy and comfortable. They are a bit of a pain to fit but once they are on you will have a much more comfy set of headphones

Very comfortable and easy to fit

Did exactly as they are supposed to. They feel comfortable and they do not hinder the sound. Great replacement for the original foam ones. No problem with the feeling to warm either

they didn't fit my porter pros.
