You've got to be kidding.
You home has been invaded, you may not know exactly where they are or how many there are; and your first move is to put ear plugs in? You will be handing them a big advantage, that's for sure.
If you are concerned about your hearing, a short barrelled .357 is one of the worst choices you could make unless you are willing to downgrade to 38 specials for indoor use. Magnums are loud to begin with, and short barrelled guns are even louder. My advice: switch to something subsonic like a 45 auto or 45 Colt. Or maybe use electronic ear muffs like akviper suggested (assuming that you have the time and presence of mind to put them on). That might give the advantage back to you.
