Doctor recomended - Rudolph Optics Electronic Slim Ear Muffs

my son went in for a check up and his doctor noticed some hearing loss, we got him tested at a specialist and the said that he had hearing loss and should stay away from load noises as that would speed up any future hearing loss. I asked about hunting and firing a gun, thats exactly what they didnt want around him-- he loves to hunt. But i remember a friend had bought a pair of these at the NRA show. I borrowed them and took them to his doctor, he was amazed at the quality the functions and how they performed. He said if he used these when he hunted he would have no problem with guns being fired around him. He now can hunt all he want but he must use these-- they saved his favorite hobby
