Good ideas, thanks. Trying not to go into public places much (I'm in a city with terrible COVID numbers) and trying not to patronize Amazon. Ace hardware suggested pads they have for washing machines, 7 bucks but they said they stink something terrible and I should leave them outside for a day or two before bringing them inside. Yoga mat makes sense but I don't have one I can chop up. Sorthobane is pricey! Looked around. I really shouldn't be playing as loud as I was to make the head dance like that anyway when solo, but once gigs happen again will be glad to have proactively addressed this (also have a fresh set of Etymotic Research ER20XS' accordingly).
