    FAQ

    Is 37 dB NRR considered high?

    Yes. 37 dB NRR is among the highest levels of passive hearing protection available in earmuffs.

    Are the cushions replaceable?

    Yes. We offer a Decibel Defense Hygiene Kit with replacement cushions and foam inserts, making it easy to refresh comfort, hygiene, and long-term performance after regular jobsite use. These are compatible with our adult earmuffs and helmet earmuffs and are especially useful in environments where sweat, dust, and dirt are unavoidable.

    Does a higher NRR always mean better protection?

    Generally, yes. A higher NRR indicates greater potential noise reduction when properly worn.

    Are earmuffs better than earplugs?

    Both can be effective, but earmuffs are generally easier to wear correctly and provide more consistent performance across users.

    Are these good for shooting, yard work, and power tools?

    Yes. These are ideal for shooting ranges, hunting, construction, lawn equipment, woodworking, heavy machinery, concerts, fireworks, and sporting events. They are also commonly used for sensory relief, concentration, and reducing overstimulation in noisy environments.

    Overall rating: 4.8 / 5 from 46 reviews.

    I have 60% hearing loss, and tinnitus from 20 years as an Air Force fighter pilot, when we did not take hearing loss so seriously. I now where foam ear buds, AND your great DD safety earmuffs whenever I use any power equipment. Have given two sets to neighbors as well, since they were not using any protection. I feel like I have the best protection possible since finding your product. Thank you. Robert Capes, Lt. Colonel, USAF (ret) 330-923-5392 F-4 Phantom, F-15 Eagle driver

    Decibel Defense Safety Earmuffs in Army Green

    Pros. Lightweight, foldable and comfortable. However, not much quieter than my Howard Leight headphones (30 net). Actually can’t tell any difference. And why do you advertise 37 nrr but the box says 34 nrr!?

    Decibel Defense Safety Earmuffs in Army Green

    Store owner replied: Ralph, the 34 is just OSHA-adjusted. The NRR is 37.

    Item works as advertised, accurate to description. The first time wearing the earmuffs over a good few hours, they were comfortable to the point I could mostly forget I had them on my head, other than the fantastic difference to sound. I'm tempted to buy more right now to use through life but I'm thinking maybe not just in case the chance a new technology for this is made. Otherwise I wouldn't buy hearing protection earmuffs that aren't Decibel Defence. These are non-electronic, they do one thing and they do it really well, the only kind I'm wanting. Buy some Decibel Defence earmuffs, seriously. Good gift. People have hearing, hearing can and will be damaged, almost everyone will encounter damaging sound many times through life. Packaging was also terrific.

    Comfortable fit. Purchased for hearing protection from hours of lawn tractor Nosie. Works as expected. No issues with shipping/delivery. Recommend.

    Decibel Defense Safety Earmuffs in Army Green

    A 37db rating proved most adequate, quiet with a comfortable snug fitting to boot. My large size just fit and I’m thinking about Xtra large next time as I wear a skull cap in the winter. I used a seamstress’s tape and measured from center left ear canal, over my head, and to center of right ear canal. My distance is 14.5/inches. Large size “just” makes the trip comfortably. (No hat) (No hair) Fast shipping, reasonable prices, acceptable marketing practices, thanks.

    THE DEFENDERS MAKE ME FEEL SO MUCH BETTER IN NOISY SITUATIONS. DO YOU MAKE ANY WITH DB PROTECTION? I WANT THE HIGHEST YOU HAVE. NANCY MACLEAN

    Decibel Defense Safety Earmuffs in Army Green

    When I tried to buy a new set of over the ear muffs I tried to get another David Clark model 19a but learned that they no longer make them. Those were the gold standard as far as I was concerned. I checked around and saw very favorable feedback for the Decibel Defense products so I took a chance and ordered some. Expectations exceeded. Very comfortable, great noise reduction and the seals even work fantastically well around my eyeglass legs. Great value, excellent product.

    Decibel Defense Safety Earmuffs in Army Green

    Excellent, sturdy, product. Exactly what I ordered. Professionalism at its finest. If I ever lose mine, I will definitely return back to replace them.
