I have a couple of really loud saws, and my ears were always ringing after use. I bought a pair of these and they cancel enough of the eardrum-blasting high frequencies to keep my hearing perfect for many years to come. My 395XP screams, but with these on, it sounds like my 334T.
They fit comfortably over the ear just like hardhat muffs and hold snug. On hot days, they do get a bit uncomfortable from sweat, so always remember to bring a towel :)
P.S. I'm a musician, so I kinda' need my hearing.
