Need Help with Ear Protectors

Our daughter gave me these ear protectors though I don't think they will work for what I need them for.  I want to use them for loud noises that are causing headaches and my ears to ring.

Is anyone familiar with these or similar ear protectors?

These are made by Howard Leight Honeywell Impact Sport Electronic Shooting Earmuff




What are these three things used for?  One on the left looks like a padded button,
On the right is something like a sliding button and what does the wire plug into?




They are supposed to be adjustable though before turning stuff I feel I need to know how to adjust them.

On the sides there are some screws, do I use the screw to adjust it?



Is the part that goes around the head adjustable?

Any help is appreciated.

If they are what I think they are, they allow people shooting firearms to hear conversation and other sounds normally -  there is a little microphone that picks up sounds and relays them to a little speaker in the earmuffs. There are electronics in it and when a very loud sound such as a gunshot comes through, it instantly turns off and does not relay that sound and they act as normal earmuffs. I believe just not pushing the button to turn them on will make them be normal earmuffs. They are adjustable - each earmuff can be lengthened or shortened where it attaches to the headband.

Anne,

Similar to what James said, they look like Active Noise Reduction hearing protection or noise canceling headphones.  They work by creating something called destructive interference which, when used properly, should be able to cancel out virtually all noise.

If they indeed are noise canceling headphones then you should be able to simply put them on, flip the switch and noise instantly goes away.

A word of caution though.  Some ANR headsets are so good at canceling noise that they leave you effectively deaf while wearing them.  Don’t worry, no harm is coming to your ears, but the noise can be so effectively cancelled that there is simply nothing to hear.  A person can walk up behind you and give quite a startle simply because they are impossible to hear.  Also, they are not recommended for use near a highway or around loud equipment because it becomes near impossible to perceive these sounds.

But if you just want to make the noise of the world disappear, then these are for you.

Thanks, James for the quick reply.

That helps explain the functions.  So I don't need them.

To adjust would it be those four screws as I just don't see any other way?

They are really tight on my head which is why I wanted to adjust the part that goes on the head.

I am wondering if they are kid-size since they are really tight.

I can understand them being tight to keep out the noise from shooting.  I just don't need them that tight.

Thanks, Eric for the explanation.

I tried them without doing anything.  They seem to eliminate the noise enough.  

I use them while sitting at my computer so I don't have to worry about not hearing any noise.

Now, my only problem is adjusting them.

Anne, I use a similar pair when I shoot and they work exactly how James said.

Unfortunately, I don't know that they are the best option for you because although they could be too small, they ARE designed to be tight. You need a good tight seal to protect your hearing with gun fire. We all take regular breaks to rest our ears / heads because otherwise the  pain just builds. I would suggest getting a pair that's not designed for shooting since you don't need that level of protection and can fit more loosely. Maybe just ear plugs?

The only adjustment I see is in the red circle. It looks like the ear cups probably slide up and down on the wire. What I circled in yellow, is that the screw you referred to? I don't think that's a screw. Notice it always matches the color of the outer ear cup? I think that's cast as part of the ear cup, to let it attach and swivel. I think it's split so the halves can squeeze together to go through the hole, then expand and lock into place.

Sonja and T Melville, thanks for the input.

My daughter called so I ask her about adjusting them.  Her dear hubby said to hold the part that goes over the head in the middle and then pull down on the earmuff part.  That worked great though I am still not comfortable wearing them.

It is war movies with cannon going off; lots of fighter jets, transformer type movies, and movies with a lot of yelling that bothers me.

Are there some lighter weight ones that work?

I looked at earplugs though there are so many different ones that it confuses me.

Any recommendations?

If you adjust the volume control, they should work for what you need. Mine do a good job of letting me hear sounds below the set volume, while toning down anything louder.

The only two downsides I've found with mine are that if I wear them a lot I tend to develop acne where the pads touch my face. And, if my neck is acting up, the weight of them can make it worse.

That said, I consider these to be a Godsend!!! I have a condition called hyperacusis. Basically, I have super-hearing, but with no way to turn it off, and no way to filter out the sounds I'm hearing. I often wear these earmuffs when working in the kitchen, because the clink of dishes or the sound of a blender running is more painful than I can handle. On a really bad day, I might wear them just sitting at my desk.

(If I actually go to a shooting range, I have to wear both the marshmallow-type earplugs AND these earmuffs.)
