That’s a neat idea, Haggis. But just a caution on using such a device. I’m currently recovering from a left external ear canal infection. And in researching what factors might contribute to a fungal infection such as I had, besides humidity and ear pH, a major culprit cited in two different reviews by M.D.'s was scratching or roughening the ear canal lining, exposing and potentially wounding, however lightly, flesh under the ear wax, etc. The reviews cited things like Q-tips and hearing aids as a source of ear infection, presumably because of the abrasion a user can cause by roughly inserting them into the ear canals. See links to reviews in following post: Dryers - actually helpful, or not?
One relative advantage of the custom semi-hard silicon molds that I have is that I can gently push them into my ear canals by pressing on the outer surface of the molds - no need to use the wires and the molds have a knobbed plastic “stick” or “wire” attached to each to gently pull on for receiver-and-mold removal.
Gary’s wire shaping is fantastic. I should bring his picture into my audi and tell her I want mine done like that!
Edit_Update: Occurs to me, too, if one’s receivers are continually slipping out and if one has to keep pushing them back in all day, that’s going to be a source of skin irritation and possibly lead to infection, so trying the various remedies that folks suggest in this thread or seeing what one’s HCP can do to remedy the situation is probably a good idea.
