SOULWIT Replacement Kit for Bose QC35/QC35 ii Over-Ear Headphones, Ear Pads Cushions + Headband + Silicone Sweat Cover - Black

Is there a good reason? If it's cosmetic issue, then I suggest you get a pair of headband and earpad cushions. I bought them a month ago and they're fantastic. https://www.amazon.com/dp/B09F343744
