Doesn't work for me
This product is worthless for me.  I tried on the items I received and there was no reduction in noise, and that's not what I bought them for.  I'm looking for something that will block out noise  from neighbors who seem to have a great enthusiasm for making a LOT of noise, and don't care who they bother.  This item did nothing to reduce or block out that noise.  Since I tried them out, that means they are used, so I will not be returning them.  I will probably just throw them away.
