REVIEW OF A FAITHFUL CUSTOMER
I first bought these years ago in Paris to keep out noise while sleeping.  In the last years I have been ordering them from Amazon and use them for my daily swim.  They serve me well for that purpose and I use them several times before disposing of them.  They don't eliminate all sound but do soften and blur it just a bit.  Wow!  I just remembered the year I first bought these--1982.
