Electronic muffs ARE WORTH the money! Buy some and dont look back. I have the Howard Leight Muffs. Best $60 i have ever spent. They really work as advertised, shutting off when the noise gets too high. I no longer wear foamies underneath, no need. I work around F-16 A/C all day and do wear the traditional muffs and foamies for that. The electronic dont have too much of a place for that kind of sustained noise!
