I've done this mod AGAIN, and it worked AGAIN. I received my AD700's back from Audio Technica's amazing warranty program, and when I tried them on before the mod I said to myself "man, I hate how these fit, they're terrible!". I did the mod today and they are so comfortable now. I've also compared the sound signature to a more neutral headphone than my previous comparison I did with the AT M50's. I compared them to my higher grade Beyerdynamic DT990/250ohm (yeah, not dead flat neutral but much more neutral than the super colored M50's). They actually sound pretty good comparatively. The AD700's aren't as musical, however, they're more open and airy sounding. I'll probably use them for gaming and my 990's for music.
Just thought I'd update!
