I finally received the replacement pads and put them on. It was a bit harder than I thought it would be, and I feel like the fit isn't secure and it will come off sooner or later. There is another guy who tried these Beyer velors and posted pics of the fit.
If you read this, can you comment on whether or not they come off?
Also, with you guys saying the biggest reason to get replacement pads was to get the drivers off the ears, but I don't think there is any difference between stock pads and these Beyers in that regard though I did roll up some tissue and stuff in there for the stock pads like within the first 30 minutes of getting them. I have only been listening as long as it has taken me to type this message, but yeah, I think there is better isolation. I was planning on doing some A|B comparisons, but I don't want to take these off again now that they are on. I feel doing that several times will damage the phones themselves with all the stress being put on joints from twisting the pads.
I do think I might prefer something just a tiny bit thicker that gives just 2-3 more mm of separation between ear and driver.
The challenge is will this help with fatigue? I will find out in a few hours time.
