3M - H7B Peltor Optime 101 Behind-the-Head Earmuff, Hearing Protection, Ear Protectors, NRR 26 dB Green

I use them every day around load generators and they work great! Would 100% buy them again! And they don’t feel strange on being they are behind the neck fit. They seal up very well around my ears!

Good quality. Very comfortable.

I got these along with my new Sthil 800x Magnum backpack blower as it is loud as a dirt bike any my ear plugs were not cutting it.As others, I wear a stupid sun hat so my over-the-head ones would not work.**Updated Review**I am updating this to 4 stars as I was able to figure out how to use the strap which goes over the top of your head. You have to disassemble the ear part then close the strap in. I can now wear them without the muffs falling out of place which was driving me nuts and not providing appropriate hearing protection. See attached pics.This still isn't a great design, but it will work. A better design would be to have a place to attach the strap though this seems to be holding in place.**Original Review**They are more comfortable than the over-the-head ones but unfortunately they seem to slip out of place when I am mowing the lawn.If I stand/sit still they are fine, but if I turn my head (which you have to do when using a rider mower) they tend to lose the "seal" and then become an echo chamber. I find I am constantly repositioning them to provide protection.Also, they don't seem to provide as much protection as I would expect. I also wear in-ear plugs with these and I still find that my tinnitus acts up after using the mower or backpack blower. Not as bad as the ear plugs alone, but I'm not sure how this would work using all day every day.They seem well built, but seem to need a strap which goes over the head to keep them in place. I believe they come with a velcro strip but I threw away the box and do not see any way to attach it.This will due until I can find a better pair.

They really work. Great for wearing wide brimmed hat while working. Quite comfortable.

These work great, just as they should.

I used these at work and once I retired i bought my own for anything noise! Cutting grass, wood worker, chain sawing etc... Great if you have hearing aids!! If you have to put muffs on then off several times, these work fantastic over in the ear corded ear plugs, that fall on the ground etc... Great product

I have been using a pair of cheap-o ear muffs with earplugs for a few years for lawn mowing and using a chain saw. They worked okay but I felt there was room for improvement, so I shelled out for these. Right away I noticed these were significantly quieter. Unfortunately, after working for a while, I also noticed that these were much more prone to slipping down when I built up a sweat. They are heavier than my cheap-o's, and I guess my medium size head and normal size ears are not the right combination to hold them up when they are lubricated by sweat. They should be fine in a cool environment of for non-strenuous activity. Mine are gathering dust.

This is a 2nd set purchased to my previous following post. Don't want to be without if I misplace the first set. These work great to reduce excessive noise while mowing with a 54' deck. : I purchased these comfortable earmuffs to originally use with my Oregon forestry/arborist safety helmet with face shield, when using my gasoline powered chain saw. I broke my original supplied attached to helmet earmuffs during a cold winter night when using with my snow thrower. I own a pair of over the head earmuffs that I could adjust the ear cups vertically, while placing the head band behind my head. But the top of the earmuffs would strike the bottom of the helmet when worn. I just finished mowing one (1) acre lawn and these and they work much better than any of my others. So, I just now ordered a second pair from the same vendor. I have to heavily trim my trees and prune my many lilac bushes next week using my different sized chain saws, and reciprocating saw. I already wear hearing aids, no desire to lose additional sensitivity.
