I work at an industry with relatively loud machinery, I use disposable 3ms on the daily, but they make my ears really sore. Was wondering if these are bad to use 8+ hours a day, and if the 27 db ones would be enough for say the noise of an angle grinder.
Can the heavy metal protection which provides 27db attenuation be used for firearm protection?
Why is Drop still selling the Firearm earplug after all the lawsuits brought by injured Armed Service members? Shouldn't there at least be a warning that they may cause irreparable harm if used as intended?
