Did not work well for me
I don't have an issue with straps around my ears.  However, I was hoping that these extenders would make it easier for me to take my mask on and off, allowing it to hang from my neck when needed.  Unfortunately, these were not really good for that purpose.  I found it hard to adjust the mask straps over the small nibs of the extender.  Once I did get the straps in place, there is nothing to keep them there!  I found that the extender kept shifting and the straps of the mask fell off.  I can't use these how I wanted to and and I wouldn't recommend them.
