They work great!
I received these ear plugs just in time for a weekend getaway. I couldn't hear the kids stomping around in the hotel room above us at all while I used them and was able to sleep comfortably all weekend!  The silicone earplugs molded to my ears really well.<br /><br />It's a great bonus having a few different pairs for different occasions, too.  Loud concerts sometimes make my ears ring so I'm looking forward to trying out another pair at the next show I go to.
