I just got my Caldwell electronic muffs. I know, they're not as cool or fashionable as the Dillon version that costs over six times as much, but they DO amplify low volume sounds inside the house. I'll be taking them to the range shortly to see how they work with gunfire. I don't see how anything bad can come out of this. These are inexpensive enough that you can buy a dedicated set just to keep next to your home defense firearm of choice. If you hear the loud crash in the middle of the night, grabbing your ears and turning them on would take only a few seconds and would be well worth the effort in terms of any amplified voice and/or protection against the sounds of gunfire. If you are in a situation where you literally do not have those seconds to spare, then you don't grab them. Simple as that. And your ruptured ear drums are not going to make your shooting any more justifiable to the D.A.
