I too started with the premise that ‘just’ earmuffs attenuating the sonic crack of any ammunition - that I may, or which a home invader fires - is a good thing. You don’t have nearly the delay for recovery of even marginal hearing and the physiologic “ring” would not be an issue at all.
If I have more than one set of electronically amplified, gating high transient suppressed ear muffs and one set happens to be next to my bed, there are very good benefits to me, the homeowner, defending my family and self; being able to hear better than I normally would and providing protection of my hearing equal to a non-active headset should gunfire occur.
The question you have to weigh, all other things being equal: is it better to protect your hearing during a home invasion incident or not? Survive the incident in the first place and you can worry all you want about political correctness because you will, in fact, be alive to do so. Not only that, you will still have your hearing in your old age.
