3M Peltor Optime 105 Behind-the-Head Earmuff, Factory, One Size

I'm a little puzzled about the negative reviews listed here. According to the Technical Details: * NRR 28 dB * Twin-Cup neckband * Patented Twin-Cup design * Behind the neck design allows for easy use with hard hats According to the Product Description from the manufacturer: The Peltor Optime 105 Earmuff is recommended for very high noise level environments. Safe, comfortable and economical for all day protection. Note, this is the behind the head model. According to the Product Description: For Extreme Noise Levels Up To 105 Dba. Developed For The Ultimate Protection In The Most Demanding Noise Environments. The Optime 105 Features Added Mass And Volume, Plus A Unique Double Shell" Ear Cup Design (two Cups Connected Via A Foam Inner Layer To Reduce Structural Resonances) To Provide The Maximum In Noise Reduction Throughout The Full Range Of Low And High Frequencies. Ansi S3.19 1974/csa Z94.2.", Nrr 29 Db Uom Each Now I purchased these "behind the head model" for one reason and one reason only: To allow myself to have adequate hearing protection while using the Sperian Protection S8500 Bionic Face Shield for adequate eye protection while using my MS 460 STIHL Magnum(tm) Chain Saw as over the head ear muffs would not even come close to allowing me to wear adequate eye protection. And you know what, the combination of the Peltor H10B Behind-the-Head Earmuff with Neckband (Optime 105) and the Sperian Protection S8500 Bionic Face Shield while workable still came up short. But that was not the fault of the Peltor H10B Behind-the-Head Earmuff with Neckband (Optime 105) . And no I have tried safety glasses with both "over the head" and "behind the head" models and the "over the head" models makes wearing any type of protective eye wear much more difficult. And because I have a tendency to "fog" every conceivable type of eye ware (including anti-fog and scrapping soap on the inside of the lens) I have purchased every conceivable type of protective eye ware and they stay on much better with the "behind the head" models. (I did fix the problem by placing a Velcro scrap at the the bottom of the face shield then fastened the strap behind my neck which held the face shield in place). The Peltor H10B Behind-the-Head Earmuff with Neckband (Optime 105) does everything it is advertised to do and it does it well. Yes there is a Velcro strap that fits on top of your head and this does secure the ear muffs better, but even with my chain saw the ear muffs stayed on without using the Velcro straps. And these are not Tactical Hearing Protectors which block out harmful noise while amplifying low-level sounds and never claim to be. So to get these hearing protectors to "better hear" music or the spoken word makes no sense what so ever. While my personal preference for hearing protection remains "over the head" ear muffs, I doubt you could buy a better "behind the head" ear protection, especially at this price.

These are AWESOME earmuffs! Super comfortable, fantastic noise reduction, and they don't mess up your hair or rub the top of your head. I use them with power tools and at my desk -- indoors, they block most sounds that would distract you, but allow a small amount of noise through so you don't feel deaf. If someone walks up directly behind you and speaks, you can hear them, and if you're using a PC keyboard, you can still hear faint clicking. If you tilt your head ALL the way back, the wire might make contact with your neck, but not in a way that's irritating. These earmuffs DO come with a strap that can be attached over the top of your head if you want to use it while wearing a hardhat (not sure why it's not shown on the product pictures) but it can be removed fairly quickly and easily if you pry off the outermost black ear foam pieces. The design is just about perfect in that the seal around your ears is tight without being TOO tight. The ONLY drawback I'd cite is that if you're working outside in really hot weather, you'll get some sweat build up between the ear cushions and your skin, and that can cause the ear muffs to start to slip down slightly. If you think that will be a problem for you, use the head strap or get the model with the over-the-head wires (I sometimes find that wearing the earmuffs upside down helps with sweat-induced slipping for some unknown reason). And I almost forgot -- I wore these on a recent airplane trip and they were terrific -- I was asleep within 5 minutes of putting them on, I felt a lot smarter and more frugal than people with their big-bucks Bose noise-cancelling headsets, and at the end of the flight, my hair wasn't messed up. :-) Yes, it IS possible to put ear-buds in your ears and then wear these headphones on top of them. Overall, I would buy these again and again.

Hello to all who seek knowledge on this product! I recently purchased these for use at an indoor gun range. They performed very well and are extremely comfortable. The NRR of 28db was very important to me. As a guitarist and music lover (I'm ebealienhead on YouTube if you care to listen/look) I try to take very good care of my hearing. Let me also just say that when I shoot (Glock 30sf 45 auto) I also wear foam earplugs with a NRR of 29 in addition to these muffs. Worn together you have the best hearing protection available... Depending on the situation you don't always need to double up, but when firing a pistol at 158db for 30 min or an hour (and others next to you shooting as well)It's a VERY good idea. These muffs would be PERFECT for machine shops, mowing the lawn, leaf blowers, shop vacs, etc. I gave these a 4 star rating only because they might slip off on someone with a smaller head. They seem to stay put for me (without the stupid over the head strap). I bought the "over the head" model as well which are AWESOME. I got these as a backup pair or for shooting with a friend. Lots of padding and very comfortable to wear. The thick padding did not interfear with the polycarbonate protective eyewear I use on the range either. So, in a couple of words, BUY THEM...They are worth it. Just be aware they may feel "too big" to some people. PROTECT your hearing! If your ears ever ring after a loud noise, or prolonged exposure to noise, you've done some damage. Wear these when you KNOW you are going into an enviroment where noise is excessive or prolonged. Enjoy!

Very pleased Fit nicely even when wearing a hard hat Unlike the ones that clip onto the hard hard these I can use them outside of work As for the noise protection would definitely recommend them for generator or compressor rooms. And for more protection you can also wear foam ear plugs in addition to these

Llego rapido y en buen estado. Se sienten comodos. Esperare a probarlos por lapsos de tiempo largos.

Great hearing protection if only somewhat unsuited for prolonged periods as the weight causes them to slide down taking your ears with `em. Best used for short periods.

The sound proofing is really good and they have held a decent amount of time.

Ears hurt if worn too long!
