Earplugs 3M Ear Combat Arms 4.1

The Combat Arms Earplugs (CAE) 4.1 from the American brand 3M are designed to protect our ears from harmful sounds, such as those produced by firearms. With these earplugs you will still hear your teammates, but they will insulate you from loud sounds.

It has a lever to open or close the sound filter, with the open mode you will hear more easily what is happening around you and it will filter sounds that are more than 110dB. With the closed mode it will isolate you from continuous sounds, such as the engine of a helicopter or other vehicles.

The open mode will be active when the "CAE" part of the lever is depressed and the closed mode when the "3M" lever is depressed. Since you will not be able to read these letters on your earplugs when you are wearing them, it is easier for you to learn that the upper position is closed and the lower position is open.

It has a retainer so that the plugs do not move even with sudden movements. The sound filter is patented by 3M Peltor.
