This is mostly “like” on these ear muffs. I have been using electronic noise cancelling earphones on the range for many years as a range officer and have found them underwhelming. I first used these last week on a recommendation from a colleague and have found them excellent. They mitgate the more acute, high decibel noice very well and in combination with earphones are really good. Voices can still be heard, although somewhat muffled, are quite audible. Preparation of the ear before casting is very important and curing is very rapid. These earplugs might be a little hard for some but cirtainly do the job.
