These solid modules can be used by themselves with the included foam tips, or with the optional custom-fit silicone mold as part of our Arsenal Hearing Protection System.

The solid modules are designed to provide maximum isolation from environmental sounds.  With the included foam tips, the peak reduction value will be approximately 27-30dB.  If you use them with the custom molds, the peak reduction value should increase to between 29-33dB.

THESE ARE THE SOLID MODULES THAT INSERT INTO CUSTOM MOLDS.   THESE ARE NOT THE CUSTOM MOLDS....YOU MUST PURCHASE THE CUSTOM MOLDS BEFORE THESE MODULES CAN BE USED.
