I;VE BEEN USING dc h10-13.4 SINCE SEP 2001 and very happy with the, they have never missed a beat and very comfy, even when doing 8 hrs in a day. I use the ear cup socks, much more comfy when u sweat, stops the gel pieces sticking to your skin.
But, I;m wondering do the socks reduce the noise attenuation at all?
