I wanted a pair of these so I borrowed some old Peltor Electronic muffs from my dad. I don't know the model but they're tan and probably 7 years old.
Turns out they pick up the fluorescent lights in the range. I don't mean the sound the lights make, I mean the 60Hz interference form them making it impossible to hear. The lights are about 3-4 feet above my head where I shoot.
Is this the nature of them so a newer pair would do the same or have they improved the newer ones?
