Perfect fit
I’ve gone through a number of previous types and finally found these.  The size is perfect making them the most comfortable earplugs I’ve used thus far.  I rarely have them come out of my ears during my sleep time.  The case is a nice bonus to prevent losing them when not in use.  The little tab cinches them into the little crease (helix) above the ear canal and also makes it easy to remove them when you wake.  The noise cancellation is pretty perfect too.  Since there were 3 in the order I’ve got backups just in case!  Very nice!
