re: Review: Festool Hearing protection GHS 25 I

I’ve also got these. 31db. Which work really well, but are a bit bulky and don’t always stay put on my head. Most of the time they stay put, but sometimes slip down to my neck…the ear parts stay in place just fine, so it doesn’t effect the hearing protection.  They’re an interesting design that allows certain frequencies through so you an hear stuff you should be hearing, but not the bad stuff…black magic I tell you!
