The resent thread “Best and most comfortable ear protection” got me looking around for a second pair of muffs. I wear 3M Peltor X5A muffs in the shop and particularly when running my cnc router. Rated at NRR of 31 dB they work very well.
I found a pair of Fnova muffs on Amazon claiming NRR of 34 dB for an unbelievably cheap price of $12.99 and had to give them a shot.
Running the PC7518 in my Benchdog lift at full tilt I could not tell any noticeable difference between the $13 Fnova and the $35 3M muffs. I can’t comment on durability but the Fnova’s will be used as a second set. Comfort level was about the same for both.
