Hi Mike,
I think the ortoplastics are going a step further - allowing adaptation for the noise enviroment youŽre working in.
The additional mic you can have makes the thing great for crewmembers, who stick their head out to give us the guidence we need in smal places or while winching.
With the pricing I found for CEPs, I think you can also afford ortoplastics - and have state of the art protection.
In case I find the appropiate homepage, IŽll post it hear.
