JCK HS36 is an intelligent active hearing protector and two-way radio headset. 

The active-volume function gives the user a very pleasant sound reproduction with minimal interference due to how smooth it is to adjust it. IP56 rated dustproof and can protect against high-pressure water column flooding.

Level dependent hearing protection function for situational awareness that let you hear ambient sound, such as conversation, machine sounds and warning signals.
Active level dependent earmuffs which build in amplifier and stereo ambient microphone provide the ability to hear sounds occurring around you better while wearing the earmuffs than you can without any protection. With the earmuffs in place, your heating is enhanced through a built-in amplifier.
