I had an absolute 'mare getting a set of customs that fit. Cosmic Ears, Custom Art, Empire Ears, Inearz. You name it I tried it. No dice. The common theme for me was that I was using the same audiologist each time. That was largely down to lack of choice where I live. In the end I gave up for a while. Then out of desperation as I find iems virtually unwearable for me (right ear small is too small, medium up is too large)I tried a different audiologist. First time fit. Couldn't believe it. Difference was this one listened to what I was asking for and read the instructions (as well as watching the video 64audio has up on youtube on how to take impressions properly).
Maybe campfire audios "audiofile" fit would be a good match for you
@ddfcoold ? Shorter option for the canal and doesn't go past the first bend? Either that or try a different audiologist?
Irony is thanks to 2020 being 2020 and additional health issues on my part, I've not been able to get back to the same audiologist yet this year!
