I have read conflicting information on this with some statements that both acrylic ear molds and silicone might need either the lab that made them or a local professional replace the receiver.
Since the “correct” answer might depend on the manufacturer and other factors, let me narrow things down. Likely that Costco will recommend custom molds to me based on audiogram and I prefer to at least have the option of being able to change the receiver myself in case of wear/tear or emergency and wishing to minimize in-person visits. I know Costco uses both Westone as well as Phonak for custom molds for their KS9 -10 aids. Can anyone confirm whether either of these is not glued in and in general would allow for at home receiver replacement?
While I will ask directly of Costco during appt, I am wanting to gather as much relevant information as possible beforehand so that focus of time with fitter is on things generated from testing and in the moment interaction.
EDIT TO ADD my SUMMARY: Read thread for details … For custom molds (seemingly both silicone and acrylic) if you are replacing receiver with same power and therefore it is the same size it will fit existing mold and most likely one can DIY.
