gzhang11Perfectly fine. Not as much reduction as something designed to kill as much sound as it can, but I spent a day on the range with these and had no ringing or ear fatigue whatsoever.
It is. And don't even consider using these at an indoor range.
Protect your ears and use the best NRR plugs/muffs you can when shooting... do not use these.
gzhang11Do NOT use these for shooting! They're not designed for transient protection, they're designed for flat response. For shooting, you want something that has more extreme protection, like ear-muff-style protectors!
