Replacement ear muffs for Stihl forestry helmet?

[NuclearNick]

Had one of mine snap off yesterday. Doesn't look like Stihl sells these separately that I can tell, and I don't really want to buy a whole new helmet. Anyone replaced these with standard hard hat earmuffs? There are some better ones out there than what comes with the Stihl helmet, but the mount on the Stihl helmet doesn't seem compatible with standard hard hat ear muffs.

Stihl dealer ordered me one a few years back when mine broke. the replacement muff was more expensive that the husky helmet sold at home depot. i bought one of those too. it's more comfortable than the stihl anyway.
