Labtec AC3FREGN Headphone Replacement Pads, 2 Pair

These pads are 1-1/2 x 2 - inch ovals. They stretch easily to fit my PX 100 'phones, which are circles of about 1-7/8" diameter.

Bought these for Koss Headphones and they fit perfectly. However, the Koss Headphones I own have a 1 1/2" round diameter. They do stretch to fit headphones that are 2" round or oval in diameter, however, it is tricky to place them on and also on the larger headphones because of the stretching they become THIN and FLIMSY! That being said I will leave you easy instructions on how to install these headphones:
1) If working with the behind the ear type of headphones, start with the area behind the ear wire.
2) Very slowly and very carefully place the foam in a small area at a time. This does take time and patience.
3) The headphone cushions will then fit tightly on the 1 1/2" earphones.
Make sure that you have all of the OLD cushions off before installing the new set for the best fit.

These will fit on the STANDARD SONY HEADPHONES 2" OVAL type, however, it takes longer to install them and also much more patience! But worth it in the long run!

These are not the highest quality, but they work just fine. They stretch! So i actually am using them on a smaller size and a mid size. The mid size i am using them on is a 2x3 inch sized headphone. They are a bit thin after stretching them, but much better than what i had and for the price, who can complain....
