Thanks to this feature, these earmuffs have a Noise Reduction Rating (NRR) between 2730 dB* (depending on the attachment type), making them an ideal choice for use in airports; construction; manufacturing; food, beverage, & agriculture; oil & gas; heavy manufacturing; pharmaceutical; and transportation. For noise levels up to 105 dBA, these behind-the-head earmuffs feature double-shell technology to provide effective hearing protection β€’ Patented Twin-Cupβ„’ design has soft, foam-filled earmuff cushions β€’ Behind the head design allows for easy use with hard hats β€’ Liquid/foam filled earmuff cushions β€’ Color-coding for compliance sighting β€’ Noise Reduction Rating (NRR)*: 29 dB. CSA Class AL *The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is Leading the Advancement of Hearing Conservationβ„’. Review: Perfect for their intended purpose: Work - Having used several variations of 3M's Peltor series of over-the-ear hearing protection devices in the last decade, I can say that their quality is excellent and that they excel at making durable, serviceable equipment for working in high-decibel environments. This is the purpose of the product: to reduce damaging sound levels so that work can be safely performed in high noise environments. They are NOT designed for sleeping, to make quiet environments silent, or to block out annoying conversations and noises around you. They are made to prevent hearing damage and hearing loss, not to dampen down your brother's snoring in another room. Anybody buying them for any other purpose is setting themselves up for disappointment, and setting the product up for failure. Several negative reviews of the product reflect this attitude. So far as durability is concerned, they are all on par with any other similarly designed product that I have encountered. They are not "bomb-proof", so to speak. The ear pads will eventually give up and require replacement. This is normal. 3M sells a "hygiene kit" that replaces the pads and foam specifically to address this. The pads are designed for a good seal to the ears even while wearing glasses, and they accomplish this. They give good service, and I am speaking from the perspective of using them for 8 to 12 hours a day, on a daily basis, in heavy industry. My previous pair has held up for 6 years. The ear pads are starting to tear on the edges, but still provide a great seal. I only bought new so I could switch to a behind-the-head design. I highly recommend the brand and the product. desertcart's rating system for these is less than ideal, as these do not "cancel" noise, but merely attenuate it. Be aware of that when readings reviews. These DO NOT "cancel" noise. Review: Confused Over the Critiques - 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. ## Features - Noise Reduction Rating (NRR) between 27–30 dB (depending on the attachment type) - Double-shell technology boosts noise-blocking ability - Made with soft, foam-filled cushions - Stainless steel construction resists bending and warping - 3M E-A-Rfit Dual-Ear Validation System testable - For industrial/occupational use only.

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.
