We have discovered, through customer feedback, an issue with the screw which holds the pivot assembly to the base of the ear muff. The screw can back out and loosen after several uses.
We have corrected the issue in our manufacturing process with a longer screw which now extends into the base securely and will not back out.
We have approved a fix for current owners which can be done very quickly at home or in the field.. Simply remove the screw and apply a strong adhesive to the threads and re-install the screw, tightening only until snug. Do Not Over-tighten! This will strip the plastic material inside the base. Be sure to use an adhesive which will adhere to both plastic and metal, such as "Loc-Tite Super Glue".
We apologize for any inconvenience and if you have any questions, please call us at 1-800-764-9969.
