Costco custom hearing domes

I know Costco can do custom tips (moulds)

I have a pair of custom acrylic molds on order from my Costco now … will pick them up any day now.
$105 from Resound for my pro 30’s … so I know them can have them made .

I got custom molds from Costco for my KS7s a few years ago.

What’s your audiogram like? IF you have good low frequency hearing and especially if you have small ear canals they may feel that they can’t give you a big enough vent to avoid occlusion. That would be my guess but you can always ask them for clarification.
