Portable Replacement Cushions,Black

I got the Koss PortaPro headphones when they were new, I think it was 1998. They're a really nice set of phones, BTW. Not studio monitors, but I worked in a boring lab job, and needed quality sound. Those delivered. That is, until, about 8 or 9 years later when the foam started disintegrating. I saw rotten black poly in my kid's ears when he borrowed them. These pads fit perfectly. They have been in place for almost 4 years now, and they have not disintegrated. I'm speaking directly to performance and longevity, now: A single set of these pads has been in place for almost 4 years, and has not started to break down. Granted, I use these in climate-controlled conditions only... but they're lasting so long, I don't even know where the package is. And the sound quality has not deteriorated in the least since this replacement. If anything, they restored the balance that was lost when the old pads degraded. I have and will continue to recommend these to friends. _____________ Update 2018: I just bought a new pack of these. I only used 4 of the first 6. My kid tore one, I lost another. The 4 that I used lasted almost 9 years. The second pair disintegrated almost completely after about 4.5 years of storage and 4 years of use. I consider that to be outstanding construction. However, I can also say that I would prefer a slightly lower-priced 4 pack of these, because I think that 9 years from now, I'm gonna have two pads left that I can't find, or are stiff from age without eve being used. Plus my kids grew up over the intervening time.

We have ordered these previously and they are an exact replacement for our Koss Porta Pro headphones. Considering the free shipping, the price was very reasonable and delivery was overnight. How can one be anything but pleased?

Fits perfect for standard headphones.

This is certainly the right product (matching diameter of the ear piece) for my headphones. I had found the information on compatibility provided accurate enough for my needs. At first, I was unable to get the replacement cushions to install properly. There are no installation instructions on the back of the package, or even hints as to the proper and safe procedure for getting them on. Eventually, what worked for me was to use an ordinary table knife (with a rounded tip) to slowly and progressively (going around) force the overlap edge of each cushion piece into the gap between the "speaker" and the earpiece cover. This had to be done gently and carefully to prevent holes or rips. The replacement cushions appear to be thicker than the original set of cushions. They feel comfortable and the sound quality is not affected (but the volume seems to be lower). Overall, a reasonable "fix it" product.

It went on perfectly Much cheaper then replacing the earphones

Took a while to get the Koss KTXPRO1 Titanium headphones apart to change the foam. It felt like I was going to break something for sure. Hint-move speaker from head band pry up around the edge, once you pry a little bit, gently twist back and forth a little bit and it will pop out.

I got these for the Koss KTXPro1 headphones, where the old pads were disintegrating. I thought it was going to be as easy as removing what was left of the old pads and slipping the new ones on. Not so much. First I tried to remove the old pieces with a toothpick and tweezers. After 10 minutes and not being able to fish out all the pieces from between the plastic, I searched the internet for tips. One said to gently pry the speakers out of the headset with a screwdriver. What they failed to mention was that there was a dab of rubberized glue holding them in. But with great care, I was able to pop them out without damaging the headset (but it was touch & go for awhile). After removing the speakers the replacement was easy. Then they snapped back in and seem to be holding securely (even without re-gluing). The final product looks like brand new headphones. I'll knock off one star for it being so difficult, but I would buy them again (especially since I know the trick now). Note: I just found another review that suggested tucking the pads in with a toothpick or butter knife (instead of removing the speakers). I might try that next time. UPDATE: I just replaced the pads on my Koss KSC75 headphones. MUCH easier - popped the old ones off and the new ones on. I gave the third pair to a friend who used them on a different brand and she had no problem either. Just the KTXPro1 was difficult. Raising my rating to 5 stars.

I have an older Koss headset and these do not fit it. They are way too big and fall right off.

die Ohrpolster halten äußerst lange und sind gut gefertigt und liegen angenehm auf dem Ohr auf. Man kann sie schnell an die Kopfhörer anbringen.

Excelente produto e fornecedor entregou dentro do prazo estipulado.

Ideali per rimettere in ordine le cuffie Koss Porta Pro (fantastiche per la loro fascia di prodotto) quando i cuscinetti si consumano. Ricambio originale e perfetto. Assolutamente consigliato. Amazon, come sempre, top!

bien
