NRR (Noise Reduction Rating) is the industry wide measurement for how many decibels sound is reduced by. The higher the number the better and at a 32 NRR these are both extremely effective and affordable. Another thing to keep in mind is how they fit your individual ears as better fits will equate to better noise reduction.
With 25 pairs in a jar these are an excellent buy and make for a great item to keep in your shooting bag, especially if you bring friends to the range frequently.
