Slim Foam Earplugs
As a highly sensitive person, I need to have a pair of earplugs on my nightstand and in my purse in case I find myself in a store with loud, annoying music.
They come in handy at the movies too-- movies are just too loud nowadays. The slim fit stay in better for me, they are made for small or sensitive ear canals.
The 10-pair includes a flip top bottle which makes it convenient to take with you.
