Have anyone tried Fostex premium replacement pads from this eBay seller ?

I bought a TH610 replacement pair to fit my TH900 and it is completely amazing sound now. At first sight, it looks more of a TH-X00 pad without swollen foams inside, allowing the user to be closer of the drivers without ears to touch them.
Compared to stock original TH900 pads, it now has globally even more soundstage and instrument separation, while almost being in a 3D sphere (totally a brand new sensation from stock pads).
Also, it has slightly less bass and allows mid-mids and high-mids to express much more and cut delicately and very slightly the “annoying” high freqs (details are still there without being annoying anymore. A total refinement), allowing global TH900 sound experience and brings it to another level. Details are still there, It’s now perfect headphones to me.
With these pads, you guys can understand easily that TH900 definitely does not lack mids at all (quite the contrary).
I listened all genre of musics and didn’t found any fail in any yet. Very impressive.
Totally recommended to give a try (moreover for 25$, definitely worth a try). Really would like to see some people opinions about these pads.
Also, comfort compared with stock is excellent, maybe even better than stock. Can listen to it for many hours without any sign of harm neither warm.
I tried recently original TH610 pads into my TH900 with ring earpiece, and I found sound much worse than stock: bass is emphasizing, not allowing mids to explain fully and are totally covered by bass, have also lost much of details. Soundstage got worse also, it’s like listening mono instead of stereo. And finally confort is not nice at all. Definitely not recommended.
Sorry for my English, tried my best
Hope this helps!
