This earmuffs are easy to install on top-slotted hardhats and noise cancellation is great. Note that if your hardhat doesn't come with those top-side slots, you will not be able to install these earmuff.

These muffs are great. They attach securely to my hat, pivot 360º, and offer superb protection for my ears.

Using these muffs, I can avoid fidgeting with inside-the-ear plugs while I am wearing gloves. But sometimes I put the inside-the-ear plugs underneath these muffs when standing next to screaming industrial machinery. Rest assured that these offer a great deal of decibel reduction.

Installation was literally a snap. The muffs are secure and have no danger of coming loose. The ear padding is comfortable after hours of use. They add some weight to your hat, however. I would recommend this product.

These were exactly what I was looking for. They clipped right on my helmet, no tools, no hardware. They pivot up out of the way when not needed. When you are ready to use them, just pivot them down. They are held slightly off the ear to allow hearing until you push them inward and they snap into place to allow a tight but comfortable seal against the side of your head. I use them when shooting fireworks (professionally) so only wear them for 30 minutes or so at a time, but they are fantastic. So much better than other hearing protection I was using, and one less thing to keep track of since they are now integrated into the helmet.

My main worry when buying these was if they fit snugly to the ear while they were attached to my hard hat. This has not been an issue. They hold tightly. I wear them around concrete trucks while they are mixing and the ear muffs brings the noise down to a low distant rumble.

When not using them you can pull them away from your ear till you feel a click, this positions them out and you can rotate them up to the top of your hard hat. You can then click them back down and they will stay snug against your hard hat. I have wore them like this for short times. When I do not need the ear muffs I generally take them off my hard hat as they do add quite a bit of weight to your hat.

They work great and are worth the purchase.

I was wearing just over-the-head ear protectors, but then my company said their insurance said we have to wear hardhats. These ear protectors made it nice to wear the hardhat. They help to keep the hardhat on and in place. They click in for snug and click out to take them off, or swivel up on the hat if you don't want them down. I put the hat on by holding the ears, and holds in place nice. This is my second purchase. I got the white Optime 95 to go onto my white hard hat and ordered these black ones to go on my red hard hat. These have a little more ear protection muffle than the white ones, but they are both great.

I work frequently around very loud drill rigs in the environmental consulting field. The greatest aspect about using these earmuffs is that I can put them on or take them off very easily and not have to worry about misplacement. Saves time and increases the likelihood of protecting my hearing instead of fumbling around for earplugs (which get dirty quickly as well).
Definitely one of the better quality of life purchases I've made.

We use the 101s in 85-100 db environments and our employees report they are comfortable and have great attenuation. They also last longer than comparable muffs.

Fits just right to my head with no pressure on my ears. It popped right into the ERB 19128 Omega II Cap Style Hard Hat with Slide Lock, Purple that i bought at the same time! Good sound reduction, still use ear plugs as well. Bonus: it keeps my ears toasty warm!
