. Peltors OK but not as robust, and no ANR option as far as I know.
Wrong on both counts.
Peltors are almost indestructible. Dont mistake their flexiblility for weakness, it isn't - it's their strength. Unlike DCs that are hard and rigid and bend or break if sat on or nuts and bolts come loose and they just fall apart.
I had a peltor that took all the knockabout in charter helicopters for five years, living in my canvas flight bag, never broke. The company's DCs? Endless trouble, until they were replaced with - well, you guess.
The noise attenuation of peltor is also
vastly better than DC partly due to their fitting so much better so ANR is hardly necessary but I do believe they do an option.
