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. 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. ## 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.

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. ## Frequently Bought Together - 3M Peltor Optime 105 Behind-the-Head Earmuff, Factory, One Size - 3M PELTOR Hearing Protection Optime 95 Earmuffs, Adjustable Earcups, E-A-Rfit Compatible, Stainless Steel - 3M - H7B Peltor Optime 101 Behind-the-Head Earmuff, Hearing Protection, Ear Protectors, NRR 26 dB Green --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/5175105-3m-peltor-hearing-protection-optime-105-earmuffs-e-a-rfit](https://www.desertcart.sk/products/5175105-3m-peltor-hearing-protection-optime-105-earmuffs-e-a-rfit) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-30*
