Replacement ear pads and acoustic foam inserts are available in kit form for the Dillon HP1 or HP2 Hearing Protector. If necessary, ear pads can be removed by simply unsnapping them from the ear protector cup. To reinstall ear pad, insert one end of the ear-pad base under the edge of the ear cup, hold it in place, then follow the edge around, pressing it into the ear cup as you go.
