Recently I noticed my ears ringing very very slightly for about ~5 seconds after every shot of 357Sig at my local indoor range - which has pretty looking sound dampening materials on the wall and ceiling. So in my short journey of searching for best earmuffs to wear on top of earplugs, I came across three very popular models.
1. MSA Sordin
2. Howard Leight Impact (Pro or Sports)
3. Peltor MT15H7F SV
One weird thing I noticed was that the most expensive MSA Sordins had "NRR = 18". But being a nerd I knew something was up. After a couple google searches I came across this interesting article
https://trevoronthetrigger.wordpres...me-performance-the-misleading-nrr18db-rating/
After reading it and realizing that Sordins could be called as "NRR = 40" (... yes I know..) I became highly skeptical about other manufacturers simply stating a single number for noise reduction rating, along with reviews from online "experts" thinking they can just add or subtract db numbers which are logs.
While my budget is limited I am willing to cry once to preserve my hearing as my shooting range allows people to shoot up to 30-06, indoors. I would like to ask if anyone has access to detailed NRR chart of the other 2 products I'm interested in, or would recommend a product they have been using for extended period of time to prove it really works - with gel pad availability because I wear glasses and the rental earmuffs I tried were awfully painful.
(Oh yes, I want those fancy microphone feature eventually, but I can do without them for now.)
Thanks in advance.
