Kirkland Aids Domes and Tails

I have the Kirkland Signature Premium hearing aids.

The come with these plastic tails to help hold the speaker dome in the ear canal.

The tails are straight and act sort of like springs to hold the speaker in place. Over time they take the shape of the ear and lose the spring effectiveness.

Where can I buy these tails and well and new domes online? (other than costco).

any advice appreciated.
thanks!

Why don’t you want to go back to Costco? They will give you new ones no questions asked.

usually Costco or any AD would just comp’ you new domes. but, if you search Amazon for Rexton Hearing Aid Domes a lot of choices come up depending on style and size.

On the tails, are there different materails? Some that perhaps dont lose their shape

what is the correct name for the tails?

sports lock or canal lock.
