Tapones 3M Ear Combat Arms 4.1

The Combat Arms Earplugs (CAE) 4.1 hearing protectors 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 colleagues, but they will isolate 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 pressed and the closed mode when the "3M" part of the lever is pressed. Since you won't be able to read these letters on your earplugs when you're wearing them, it's easier for you to learn that the top position is closed and the bottom position is open.

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