Thank you for your question. Unlike many Ear Muffs on the market ours are tested and certified by an independent 3rd party lab to verify the Noise Reduction Rating per the American National Standards Institute (ANSI) S3.19 Test Standard. The lab used is based in Denver, CO.
We also have our ear muffs tested and certified to the European CE EN 352.1 standard. We have noticed some companies do not properly follow the ANSI standard and actually list a false NRR value. This happens when companies do not fully understand the standard and fail to deduct 3dB from their test results, which the ANSI standard specifies in section 40CFR PART 211-Product Noise Labeling.
We have followed the standard as outlined and deducted the 3dB from our 34dB NRR test results to arrive at our 31dB NRR Product Noise Labeling per the ANSI standard specifications.
Comfort is important and the ClearArmor earmuffs have a snug reliable fit, padded head band, fold up easily so they do not take up much space and the 31dB NRR rating is better than other brands. When it comes to pressure on the head all ear muffs have some pressure and what each person is comfortable with varies from person to person. 98% of users like the comfort and snug fit of the ClearArmor earmuffs, however about 2% of users felt the side pressure was uncomfortable to use for long periods of time (which is similar to all safety ear muffs). ClearArmor guarantees your satisfaction, so there is no risk to try them.
These work great for hearing protection at both indoor and outdoor shooting ranges. They have a snug reliable fit when shooting a rifle, they stay in place and really muffle the sound for large and small caliber guns. They have a padded head band for comfort, fold up easily so they do not take up much room in your gun bag and the 31dB NRR rating is better than other brands.
Yes, many customers have used ClearArmor ear muffs for these types of activities. They do work great for professional and industrial users, but they also work great for Kids, Studying, Concerts, Special Needs, Auto Racing, Yard Work, Travel, Loud Neighbors, Blocking City Noises and even Sleeping.
