Portable Replacement Cushions,Black

These foam ear pads seem fine, but I struggled to figure out how to install them on my Koss KTXPRO1 Titanium headphones. The original foam pads had deteriorated to almost nothing after a few years even though I don't use them often. I found it easier to work with by first removing the speaker part from the head band; gently pry the speaker part from the two pivot nubs of the head band. Work on one side at a time so you don't swap left and right speakers. I could slip the tip of a flathead screwdriver between the inner black plastic speaker part and the outer plastic silver enclosure, but it did not snap apart and felt like I might break something if I forced it. Actually it does snap apart, but there is a dab of stretchy adhesive on the center junction where the two parts snap together. Use a fairly wide flathead screwdriver so that you can twist it to create a big gap. Work your way around with the screwdriver until you have loosened the hold of the adhesive and created a large enough gap so that you can grasp the black plastic part with one hand while holding onto the silver enclosure part with the other. Gently twist a little but mostly pull it apart until it breaks free. See the image for how it looks when you get it apart. You might pick out any excess adhesive that may get in the way of reassembly. Pull or cut out remnants of the old pad and replace with the new pad. Gently tug it into place, and push your finger along the surface from the center to the edge to help evenly distribute the new pad so that it covers the spiky nubs. To reassemble first make sure that the rubber cord strain relief is wedged in the notch on the silver enclosure. Then align the fastener part on the back of the black speaker with the corresponding part in the center of the silver enclosure. It is challenging to tell if you have it aligned correctly, but with visual approximation and a light touch you can do it. Making sure the wire is not going to be pinned in the center snapping fastener, press firmly and it will click into place.

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.

I bought my Koss Portapro in late 2016 and the original foam pads started to disintegrate around last Xmas. I didn't bother to get new pads until recently, when I finally got tired of having black foam bits cramping my style when I am in my Tide fresh white wife beater. The pic for this looked somewhat sketchy, but for about 7 bucks, why not? So glad I did. The new pads are a perfect fit for my Portapro. Installation was painless and took seconds. The headphones feel so much more comfortable with the new pads on. But the best part was the sound quality. Holy moly, I forgot how good these sound. The new pads completely restored the highs and the sound stage. The clarity is a lot closer to my Grados than I remember... and that's saying something. Without a doubt, if you need replacement pads, these should do just fine.

Initially I was planning to order some generic replacement cushions from here on Amazon partly because I did not know what size my headphones needed. The others were larger and would probably have require less stretching to get them on the headphones. I went with these as they are the replacements that KOSS says fits my model of headphones. They DO fit but I had to really take my time putting them on as they needed to stretch quite a bit before they were on properly. The generic set cushions I was considering are 64MM and these are 48mm on the outside diameter. As with most replacement ear cushions (even if they are from the same brand as the headphones themselves) they are thinner than the original ear cushions. However, they do what they are made to do which is to be more comfortable than having the headphones on your ears without padding. I give these 4 rather than 5 stars because they could be a little bigger so you don;t have to stretch them out quite so much to get them on.

They work/fit

As advertised. Good product.

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.

Works well and does the job

Exactly as I expected. These are the real thing, fit perfectly my Koss PortaPro. Well worth the price.

Good product!

Conforme à la commande sans surprise
