Not as good as my $1 pair of ear plugs...
The only thing these really do is muffle sounds. I bought these to use while I sleep on days after I work the night shift. If anything, they make it easier to hear myself breathe and my own heartbeat. I can hear someone cough in the room next to me. I have a cheap ($1) pair of regular foam ear plugs that do a better job. I'm very disappointed.<br /><br />What's good about them? They are easy to insert. I have smaller ear canals and struggle with a lot of ear bud headphones and ear plugs.
