Bests & Worsts Reviews from Amazon

I operate an indoor firing range and I purchase many sets of electronic ear protectors for my students, myself, and my assisting instructors. I have tried many different electronic hearing protectors over the past 24 years, some good and some not. I recently purchased three sets of these exact ear protectors from Grainger for evaluation purposes. I did not like them and neither did my instructors who tried them. They do not hug the sides of your face well and thus do not cap and seal well around your ears. Two of the three sets I purchased began to emit a static sound within the first couple of days. Replacing the batteries did not make the static go away. I will be sending these back. And even though I have yet to find the perfect set of amplified hearing protectors for use when around gunfire, the set that seems to be the most popular are the Peltor TacticalSport hearing protectors. This isn't intended to be an advertisement for Peltor because I steer away from their cheaper amplified hearing protectors because they don't hold up well, even with gentle use. I'm merely mentioning the TacticalSports series because the majority of my instructors (who wear them the most), prefer it. I hope this helps you make an informed decision.
