A complete waste of time and money
I purchased these "noise canceling" earplugs because the claim was that they are reusable.  And, I guess they are.  The only problem is that they have absolutely no noise canceling properties.  I tried them and everything sounded the same.  My wife tried them and had the same experience.  These earplugs do not work in the slightest.  A total waste to time.  I don't know why anyone would sell such a complete failure.  Balls of cotton stuffed in your ears would work better.
