If you have to be so nosey I buy Peltor Ultimate 10 Headphones as I have Hyper acusis, too much dynamic ripped from inner ear at a lot of Rock Concerts I attended. I hear too dam much the audioligist, said "we're working on hearing aids not antenuators for you poor people that hear too much".!
Go head make your day either ask doctor or get a medical dictionary and look up the word Hyper acusis AKA acute hearing, monkey boy. There are no batteries and the Ultimate 10 has a 29 Decibel rating for $19.95
Most shooting suppliers sell headphones to gun or riflemen to use not to lose their hearing when shooting! Stupid uninformed people making incorrect accusations. When you stop at the zoo you will feel and smell like you do at home monky boy.
