Anytime there is a chance I may pull the trigger I have some form of hearing protection.
I guess it doesn't bother me too much because I have to wear them at work 100%.
I also shoot USPSA competitions where it is required.
While hunting I wear the $29 electronic muffs peetzakiller mentioned.
They magnify sounds below 85 db and shut off on any sound above.
Yes, in Summer they can get a bit warm and if they aren't sitting just right they will irritate my ears some after 4 or 5 hours!
... after watching my Father, who NEVER wore any type of hearing protection while hunting or working, struggle to hear normal conversation, blast the volume on the TV or ask his Granddaughters "HUH" over and over, I can deal with hearing protection!
I work with a guy who has 95% hearing loss in one ear and 100% in the other! He fights with his hearing aids all the time. His loss was due to injury. But I can prevent my hobby from doing ANY damage to mine.
I choose to wear hearing protection some of the time now so I don't have to wear them all of the time later!!
