anyone with k701/702/etc replace their stock pads with these things? i have to admit i haven't used my k702 in years, as i've spent less and less time on focused listening - in favor of more casual listening (while i'm on the go) with AirPods. bizarely my stock pads had shrunk and deflated for some reason (honestly kind of disappointing considering i paid like $400 for these headphones back in the day). so i'm looking at replacements on amazon and see these real leather (sheepskin) pads are only like $15 more than the velour pads. i'm wondering if they're worth it from a longevity viewpoint
