Hi,

Just in case this is helpful:

A person does not simply stick these in the ear.

I watched my father roll the ear plug until its width is very small -- maybe almost like a pencil lead -- but not quite.

Then you are to put it in the ear and hold it in place with your finger while it fills up with air and expands -- according to something I saw on a web site years ago

That is how I do it.

And now that you explained it Waves, I will be sure to change them every so often so as to keep away mold.
