I bought a pair of the the model you are asking about but paid more for them. I wanted the best. These probably are the best that use that particular technology. However I didn't like the way they cut out loud sound completely with a resulting loud "click". The safe volume level would then return quickly but immediately after the "click", they sounded like ordinary shooting muffs.
I did some research and found PRO EAR Dimension1 headphones. I understand they "compress" the sound instead of cutting it out altogether.
With the PRO EAR I can hear everything, all the time, but at a safe level. They cost me about twice as much though. My advice is to try them side by each before you lay your money down. I gave the Peltors away.
You can't pay "too" much for something you put in front of your eyes, over your ears or on your feet!
