Ok, but others are better
The concept works for relieving pressure of mask elastic on your ears.  If you wear hearing aids, this will decrease the chance of them being knocked loose by the mask straps.<br /><br />A bit chintzy, made from cheap, so-so fabric. Maybe it’s just me, but I have a big head and they eventually get uncomfortable after 8 hours (too tight).  I have others that are much more attractive, comfortable, and better quality fabric.
