I'm interested to know if it works as well. Lawnmowers still aren't too bad but practically everything else I run I have to use earplugs now. If I ran the mowers more (dad and my son use them the most) I would wear them using those also. I'm at that point in life where I wish some old fart would have sat me down at the ripe old age of 20 and gave me a stern lecture on hearing protection and taking care of your back.
