Not one guy, go check all the headphone measurement sites out there and see for yourself how aging pads, not even different pads, affect the sound of headphones. You don't even have to listen to find out, how great is that. Start from the Sennheiser HD650
Headphone ear pads (OE) make even greater differences to the sound than IEM ear tips. I met Kennerton founder (from Russia) in CanJam Singapore a few years ago, and he let me try one headphone with multiple different ear pads, I can hear huge differences between ear pads. He said ear pad is part of the headphone (OE) tuning.
That's one of the reason I've stop buying headphones. Every few years ear pads worn out especially in humid environment like in Singapore, and every time I replace it the sound change to some degree.
