Works to avoid ear pain!
I have a couple of homemade masks and more of the basic blue surgical masks.  But I'm one of those people without "detached ear lobes" (look it up if you don't understand, but it essentially means my bottom ear lobe goes directly into my head instead of making a nice lobed hook for ear-loop elastics).  I can use these for either the homemade masks or the surgical masks and I get a mask that I can dangle below my chin before/after I need it, or that just makes the mask more comfortable when worn in place.
