Bests & Worsts Reviews from Amazon

I have been a faithful fan of the red/black Peltor/AO Safety H10A earmuffs for a good many years, but this Peltor Ultimate 10 is even better. The Ultimate 10 has the softest cushions (definitely the best and most comfortable ones I can find) and the NRR has been bumped up by 1 to 30 NRR. Theoretically the human ear should not be able to distinguish a NRR difference of less than 3, but somehow when I put it on I can feel that the Ultimate 10 with its NRR of 30 does a better job of attenuating noises than does the H10A with its NRR of 29, and they are so affordable to boot. In addition to wearing these earmuffs while operating loud machinery at home, I wear earmuffs in my office to block out typing and talking noises from co-workers, because without good earmuffs on my head, I find it hard to concentrate when I read or write. I don't like the feel of earplugs. It is very effective in blocking out typing sounds and female co-worker voices, but not so the deeper male voices. I am still waiting for new technology to come up with an earmuff that can effectively block out low, deep bass/baritone voices in the 80 to 350 Hz range from male co-workers. The Peltor Ultimate 10 is the best of all earmuffs currently on the market but still manages to block out only about 20 decibels in the 150 Hz range. The Peltor Ultimate 10 is the best money can buy right now in both comfort and highest NRR.
