When I purchased my hearing aids from America Hears, the package came with a these ear plug cones. The had different sized holes inside them. I used them as a way to increase the volume on hearing aids without increasing feedback. It worked really well and I didn’t have any real occlusion effects.
It’s been 3 years now and I’ve went through them all. I’ve looked online to stock up on them but could not find anything. I’ve basically rolled up a piece of electric tape, poked a hole in it with a needle, and pushed it into the vent. It’s working as good as the original plugs but I’d still prefer the real thing. Anyone know where to get them? Do they go by a special name besides “vent plugs”?
