The case sucks!
I have hearing sensitivity due to an injury and used to wear these plugs once or twice a day.  I wore this container on my key rings with a harbinger clipped to my belt loop.  I am giving it three stars because the case unscrewed about once a week for me and the plugs would fall to the floor. After about six weeks, I lost the plugs.  Do I like the plugs themselves?  Yes.  They are adjustable a little in the ears, so that you can cut out some or most of the noise.  The plugs are nearly invisible, but I just can't be buying another set of these every six weeks.
