they work!
Comfortable.  Very good at keeping the hurtful noise out while still letting you hear. Hard to get out of ears once in.  Would help if they had a small peace sticking out to grab hold of.  Still, I like them well enough I'll probably order another set so I can have one in my purse and one in my ukulele case.  I gave it top rating because they do what they said they would do.
