Hi,
Perhaps you should look at a product called ZEM, they have an excellent range of "ear muffs"as they are far lighter than any electronic muffs and are far more comfortable to wear. They come in different colours as well. If I remember correctly they were a bit less in price as well, as the benefits of comfort, range commands and hearing under normal conversation sound level, no problem.
I got mine from from the web site of www.bpss.com.au.
I use them with all the caliber s and they handle the different noise levels really well,I use them for everything from .22 through to a .300win mag, as well all the handguns .22 ,9mm,.38super and .357 mag all no problems.
Check them out before you part with your money as I have tried both the electronic muffs and these, and the ZEM are far more comfortable to use and have no batteries.
Regards
