Summary: Put them on an old Koss behind the head earphone. Has to stretch just a little but they work jist fine and are comfortable. Reasonable price and they were shipped to store for pickup at no extra cost.
Summary: Replacement pads for earphones are less expensive than purchasing a new headphone set every time the pads wear out. I use headphones to listen to music while exercising on aa treadmill or weight machine. Sweat is not kind to the pads and replacement pads are a great alternative to replacing the whole headset.
Summary: I purchased Koss replacement cushions for my Sporta Pro headphones. When I pulled off the original pads, I compared them to the replacement pads. The material in the replacement pads is slightly thinner and less spongy than the original pads, but they fit and feel just fine. With the thinner material, I'm inclined to think that the replacement pads won't last as long as the originals (which lasted almost four years), but six pads came in the replacement pack, so I should...
Summary: I use these on the plane, at work, and most of the time listening to music and watching movies on my HP Touchpad tablet. I have to say these are amazing sounding headphones and you would be extremely hard pressed to find ones that sound better for even if you paid $50 more. The bass has no distortion and the treble is spot on. The next point is that due to their design they are super comfortable.
Pros: Comfortable, Good Bass, Good Value, Great Sound
Summary: These are good replacement pads--inexpensive, comfortable and well made but they are very hard to attach to my Koss Pro35A headphones (same as KTXPro1). The ear pad lip on these headphones is extremely close to the body of the ear cups so there's very little space to tuck them in to. The pads keep falling out. For most other headphones, these replacement cups will be fine, though.
