Koss Porta Pro Standard Size Ear Cushions (Replacement, Breathable Foam)

Great replacement, my Porta Pros feel awesome.

These cushions fit perfectly onto my Porta Pro. They are soft and comfortable, and the installation was a breeze. The only reason I'm not giving 5 stars is that they seem a bit less breathable than the originals, but they are fine.

I've had my Porta Pros for 10 years and the original cushions were flat and uncomfortable. These replacements are thicker, softer, and more breathable. They make the headphones feel brand new. Definitely worth the price.

The cushions are decent, but they don't sit as securely as the ones that came with the headphones. They tend to pop off if you pull the headband too far. I ordered the standard size for my Porta Pro, so maybe I got the wrong size? But they fit the speakers fine. Anyway, they work, but be careful.

Cheap and effective. My ears thank you.

They are comfortable and made of good foam, but they are a bit stiff when you first put them on. After a few days of use, they loosened up and now feel great. A solid replacement.

I bought these for my KPH40 and they fit perfectly. The foam is high quality and provides a good seal. My ears no longer hurt after long listening sessions. Highly recommend.

I ordered these for my KPH40 based on the description, but they seemed too small and wouldn't stay on. I had to return them. Maybe I got a defective pair, but I'm disappointed.
