suggestions for electronic ear muffs needed

[Guilty]

I bought a couple of pairs of 3M Tekk Protection Tactical Sports Earmuff (Peltor) from Home Depot a couple of months ago when they had a $50.00 rebate going on at the time per each unit. Regular internet advertised price is just shy of $117.00 They have a 20db noise reduction rating, auto shutoff after 2 hours, and they are comfortable. Do I want Sordin's, yes but I don't want to shell out the big bucks for multiple sets of hearing protection, the 3M Peltor's definitely didn't break the bank and they perform well.
