I would like to share my story.
I got my sr60i in 2011. A few months ago I bought the L-cush and G-cush (earzonk) pads to replace the original earpads. I've been quite busy working and didn't have the chance to use them properly. I need closed back headphones at home so Grados were out of the question. I've been trying to push myself to use the L-cush but comfort was killing me, treble response becomes strident and bass loses impact. It's hard for me to understand how people actually prefer those pads. The G-cush affect way too much the sound, the whole Grado signature go to waste, although they're quite comfortable to wear.
I was about to ask if headphones sound quality decreases or change with time but then I decided to switch again to my old worn comfy pads and the sound and experience immediately came back. It's amazing how a few milimeters can drastically change the overall perception of sound.
