Last week I killed a 6.5 foot black bear in the Wyoming mountains. It was a combination of spot and stalk during the days and then sitting 574 yards from a bait for the last few hours of the day.
I wore SoundGear electronic plugs continuously and comfortably from 10am to 9 pm for 2 eleven hour hunt days. My kill shot was made just an hour before dark on the second day.
I never had to compromise my hearing health or my hunting ability.
