I did some searching and didn't find a post on here about this, nor have I seen any pics of Clears using this anywhere. So I'll go ahead and let you guys know about a headband cover I discovered on Amazon from Geekria.
And no, it's not the wool woven ones most everyone seems to be rocking (which i happen to think looks hideous imo). This is a zip-up stretchy sort of nylon one, and it matches the Clear perfectly! It's made for the ATH-M50 series so it may have been overlooked. But considering it's $15 CAD I rolled the dice and it turned out perfectly!
Take a look at the pics. Unfortunately I just finished pad swapping to Dekoni Velours, but trust me when I say the grey matches very closely. (Edit: I threw in a bonus pic with one of the original earpads to help visualize)
You'll notice it is just a bit unevenly positioned on each side. It depends on how you position it, since you have to zip it at it's narrowest part - it is not as stretchy at the ends due to the added material there - so you kind of need to start at the narrower part of the band (where Focal is embossed) and because moving it after you zip it doesnt quite seem to be possible since the velour type material on the headband is very grippy. But regardless I think it turned out great, and is much better looking to me than putting a damned Cosby sweater on my sleek looking cans
Not sure if links are allowed but here's the link for Amazon Canada, if it is removed just search Geekria replacement headband cover for ATH-M50.

It comes in both grey and black so I think I'll grab a black one too to match my dekoni pads
Hope this helps some of you keep your headbands fresh! And a bit of extra padding always helps
