YAXI EARPADS for Koss PORTAPRO 2Pairs (2P-PU+OG)

These genuinely really help the sound, and are much more comfortable than the original pads that come with the porta pros. Also certainly doesn’t hurt that they come in cute colors!

The problem with trying various ear pads is that they can alter the sound quite a bit. Sometimes a set of after-market ear pads can greatly improve the sound in a number of ways, while others may downgrade the sound qualities of that headphone unit.I'm delighted to report that these Yaxi ear pads are wonderful in so many ways. To begin with, I had purchased a pair of Koss KPH40i headphones and those chintzy little all black ear pads (if you even want to call them ear pads) resulted in a sound signature that was very thin, with little body. Sure, the music had a very open and airy sound, but with the stock ear pads, there was virtually no body or weight to the music.So I ordered this set of Yaxi ear pads and what a difference they made. They were a cinch to quickly install/apply - which was much easier than taking off the stock pads to begin with.What I immediately noticed was that the music was still quite open and airy, but now the body of the music had more weight - no longer thin! Bass was excellent and everything sounded quite smooth. In addition, because these are colored (red and gray), you can now tell which side is the right side (red color), so no more examining the headphones up close to see which side goes where.So I'm delighted with these and they rate 5 stars, especially at that low price for two pairs of ear pads.

Been buying these over and over. Wish they lasted longer but they are comfortable and sound seems good.

I wouldnt call myself an audiophile, YET. The only thing holding me back from being one is being able to spend ungodly amounts of money on audio related stuff.But what I can tell you is I have very good ears and am also a music and audio enthusiast. My ears are very sensitive, I can pick up a lot of frequencies on the high end. I often tell my friends to lower their maxed out treble (they don’t know any better and think maxing out equalizers is a good idea) in their cars because its way too sharp on my ears.Now for these pads, I have used them on both the PortaPro drivers and KSC75 drivers.On the KSC75 drivers, they make the sound about 10-15% worse. They cause the upper-mids to sound disgusting, I can’t explain it well besides that. Its not a huge difference by any means, but it makes the sound muddy but a sharper muddy that drowns out the other sound. It removes A LOT of the soundstage, the KSC75s didn't really have too much in the first place. This makes it sound like all the sound is a jumbled muddy high piercing mess.Now for the PortaPro drivers, there is a much smaller difference than the KSC75s. The difference it causes is that with the Yaxi Pads it kills the volume of the high end frequencies, and also just lowers the volume overall. It also does make the soundstage worse. It sounds like some frequencies are just “missing.”In terms of comfort, Its about a 15% increase in comfort due to the surface area. The thickness of it compared to the normal pads are that the Yaxi’s are more thick. They are not more stiffer or squishier, it just SEEMS like its a bit stiffer that way because it has more thickness.Overall, the stuff of people saying it makes the quality of the sound that much better are just people who bought into the marketing and monopoly the Yaxi Pads have over the Koss’s. Its as simple as that. Its not a miracle product that enhances the sound quality. All pads can do is just block or allow some frequencies to pass through.If your ears hurt from the pads, go ahead and get them. If they dont, dont waste your money thinking these will make it sound better. Only a high quality equalizer (or better drivers) will do that for you.The way I tested the differences were setting my audio to mono and replacing the pads on one ear and keeping the old one on the other. And yes, I tested each side on both ears.

Looks great, good material and perfect fit.

Absolutely fantastic. Makes the Koss Porta Pros so much more comfortable, and gives them a warmer sound.

Decent enough value. I'll buy again once they wear out. They last about a year per pad. Assuming you wear them every day for a few hours a day is about a year.

Not much to say here. If you have Koss PortaPros, you should replace the stock cushions with these. They offer more comfort and a better sound stage at the expense of a very small (tiny) reduction in bass.
