Might be a given today . I have no idea but it sure wasn't when I spent my many falls in goose blinds with friends or clients
Not saying that was wise or smart but like Tyson 10ga only wore them shooting targets and at a range 100% over the years never hunting
The guys that did I hunted with in blinds wore products made by Walkers or Honeywell Howards and still do to this day and forced me to take that dam 10ga to the end of the blind
Never had anyone wear them upland or deer hunting
I might have been lucky god knows but hearing loss is not something that has hit me at all even with a career in heavy industry and a high use of power tools and I get tested fairly regular since lots of hearing aids in my family and my poor mrs wears two and makes me get tested all the time
As good as I was at 19 they say. Glad something is not falling apart 
Even a good goose call is over 85
What models are you using now just the ear pro ?? or pro ears??
Cheers
