How do the ear defenders work?
These ear defenders have button to turn them on and off: an acoustic signal sounds when the defenders are switched on and off. Two buttons (+ / -) are then used to adjust the amplification volume. These defenders are active: they have a sound modulation system to remain in contact with the environment, while attenuating acoustic shocks (ambient noise is reduced, but audible frequencies are maintained).
Our tips
Depending on your activity (target shooting, clay pigeon shooting, hunting) and the location (shooting range, lowlands, forest, etc.), you can adjust the amplification volume. So you need to be able to hear your environment, there is no point in over-amplifying it. Please note:
-when outdoors, pay attention to the wind, which will create a blast effect in the microphones.
-do not use the ear defenders when the amplification system is switched off: they will not protect you efficiently.
