PERFECT !
I bought these for a friend who's in a nursing home.  It can get pretty noisy there -- any time, day or night.  She just loves these earplugs.  They're easy to use and they work just great.  They are a replacement other earplugs that I had gotten for her that were not satisfactory.  And, these were much, much cheaper -- less than half the price of the others.
