3M PELTOR Ear Muff Hearing Protection, X5 Series, Noise Protection NRR 21 dB, Construction, Manufacturing, Automotive

The tabs fit right into the side slots on an old hardhat. The muffs rotate up, or down to the ears. The fat, mushy, soft seal fits around my glasses stems without pressing them into my head. They really SEAL. They do a great job blocking most sound. They are the quietest I ever used. The number 31dB was the highest I could find. I believe it. It is as good as I would expect from 3M, who in my opinion, has thus far always been representative as a standard of top quality.

Can't believe how well the noise atinuators work on my old hard hat, much better than plain ear muff types.

I work in a mill. To put it simply, it's deafening 24/7, to the point where you're hoarse every day from trying to communicate with people. I bought these muffs because the foam plugs hurt my ears after a while. To be honest, I think these particular muffs reduced decibels more than the 3M plugs that the mill had available to use. I rated noise cancellation on these muffs 3 stars due to the fact that they greatly reduce noise, not cancel it. If noise was cancelled, this would be a safety risk. For a 12 hour shift, these muffs are super comfortable and actually aid with holding my hard hat on my head. With this being said, in warmer weather you will perspire more with these. I definitely never put these muffs up on my hardhat as it makes the hat too top heavy and unstable. When I don't need the muffs, I kick the springs out so they still hang down and away from my ears. All in all these are a great buy. I highly recommend!

The media could not be loaded. This product is an affordable substitute for the Trend Airshield Pro earmuffs.Lightweight and very effective in continued use with durability and adjustment.

My kids play piano in my home office. It's too loud for me to concentrate on work.These ear muffs dampen the noise enough for me to work.The disadvantage is that it is very hard to hear what people are saying. This might be a problem in a high-risk work area where hearing verbal warnings is essential.I already had a hardhat, and I think these ear muffs are more comfortable than the over-the-head model, especially if worn for a long time.

A little heavy to balance on helmet when folded up but work well.

Package looked open, outside looked dirty, but it looked new inside, I have been using for two weeks and they are very good. Comfortable, noise cancelation is very nice.

These will not work with a full brim hard hat, as in most MSA hardhats that you’ll get on wind or solar projects this will not work.LUCKILY for those of you who have a normal MSA hardhat, the swivel mounts on the side of the earmuffs will also fit the same behind the ear adapter as other models. As I had some older ones laying around, switching them out makes it work perfectly, however they will function a little different as they’re not attached to your hard hat as the product is sold.Keep in mind these are meant to be mounted, so if you’re using this method to make them work with a bigger hard hat, the weight from these and extra width and be a little awkward if you don’t have them SITUATED. Also given that they’re gonna have different amounts of pressure applied to your head, this could potentially change its effectiveness but I have not noticed. + I may already have hearing damage lol
