It is using in a room shooting field of large-caliber rifle. When the outdoor is good for in earplugs, but insufficient in the shock wave also have ear plugs at the time also of bullet shooting many times the speed of sound in the room. But is a better price if you buy at the gun dealer ... and cheap to buy here has been very happy.
