If that's the case, and I can believe it, I'm going out tomorrow and buying full muff style protection, sod the expense, as being blind is one thing but being deaf as well, I don't stand a chance.. ;-)
Go and have a look, but you will need to look at the 150 plus ones.
My friend who started shooting recently, looked into the electronic muffs. The 90 quid pair broke as they were being put together in the shop, the 3m ones worked, but are massive and even more money. I was there
They will interfere with your mount.
I have been shooting big bore rifles and shotguns for 15 years. I have always used protection.
I used to use a pair of Peltor muffs when shooting big bore rifles, worked great but did get in the way a touch.
They do make your ears hot and uncomfortable.
Foam plugs do a great job and is what I used for a long time.
Mind you, I not being a trap shooter doing hundreds of rounds under cover, have probably had it easy on my ears...!
I have regular hearing tests through work, and my hearing is very good.
You can do more damage to your ears with a loud stereo or an iPod.
I'm going to get a pair of molded jobbies. If you are that concerned, perhaps get some molded ones, then couple them with some regular muffs, which are lower profile than the electronic ones. Then, when you want to hear what is being said, the molded ones will still offer protection from shots going off around you.
