This makes so sense at all, forget the domes and go for custom made molds, with say 1mm or 1.2mm vent (not to big as you’ll get some feedback)
you’ve got to try and get the gain needed from the mid to high frequencys, with any type of dome your just not going to get the required gain without issues.
This is hardly surprising, your not correctly fit, you need to try other things instead of trying to get things sounding like your old bernafon models, correctly fit HAs are going to sound “very loud” to begin with, but over time you’ll get used to them (well hopefully)
You don’t want your new HAs to be the “same” your old bernafon, you want to improve, so you have to set whatever you end up getting differently.
Why not just update to a newer Motorola or something, quite cheap for getting the maximum use of any HAs that can use direct streaming to android.
Again I’d say because they’re not getting correctly fit, your loss is not an easy to fit,one stop set up, takes time and an experienced audiologist to help you get the maximum benefit from HAs.
I don’t actually agree with this, no use just focusing on these ffrequencies for speech comprehension, Brio 5 you need to give a trial so you can be sure yourself if this actually the case for you.
Again I don’t agree with this, you need to try for yourself, with the correct size vent to your satisfaction, molds will be better then any dome available.
So in short, you gotta find an audiologist with experience in your loss, and you definitely need to trial for a much longer period then just in the “store” as this not going end to well, as it’s just not long enough.
