Depending on your activity (shooting, hunting,etc.), the venue (shooting range, lowlands, forest, etc.), you can adjust the amplification volume.
While you need to be able to hear your environment, there is no point in over-amplifying it.
When outdoors, pay attention to the wind, which will create a blast effect in the microphones.
Do not use the earmuffs with the amplification system switched off, as they will not provide sufficient protection.
