I use earring aids and most face mask will pull them off my ears. I walk on a greenway on many days and it is important that I hear when a person or bike is coming up behind me. These work great for that. Also, I was a parachute rigger with the 82nd Airborne and again with the 1st Cav in Vietnam. My duty took me to sitting behind a sewing machine all day every day. I know first class workmenship and this fits the description of their product.
