This is a long shot, but. I have an HE-6 that I'd like to try pad swapping with it. I got the dimensions of the pads from a Redditor and the dimensions seem to be exactly what I'm looking in comfort and potentially in response (I'm currently using Dekoni AD elite velour pads so I have those as a reference).I can measure the frequency response and THD of your specific pair (though THD is a bit inaccurate in the bass due to not having a proper acoustic chamber).Picture of my MiniDSP EARS: http://imgur.com/a/f67d8L4 The ADX5000 pads cost about 135 USD a pair new from Audio Technica US and that's too much for me going in blindly.so if I get them on Monday, I send them out Tuesday; Saturday, then I send them out on Monday.Smoke-less and pet-less home.You can check my feedback here on Head-Fi for confidence.Thank you!
