If you're in need of two-way hearing protection, look no further. The olive end provides constant passive NRR of 22 db. While the yellow end features a filter that allows normal conversation while simultaneously blocking harmful noise levels. Patented triple-flange design provides a custom fit. Per pair.
I use this product for hunting and shooting. I like how it protects my ears and I am still able to hear what is going on around me. Product preforms just as advertised.
I've been using theae at the range for several years and think they are great. Comfortable for long term wear, sufficient noise reduction. There is a difference between the yellow and green ends for use as you need it. I do recomment these.
