which brings me to this question: These custom iems sit flush with the ear, so you can sleep on your side with them? And if I were biking with them, they stay sturdy in the ear compared to universals? And do the cables provide the least amount of noise from movement possible? I don't recall these points being mentioned previously, and these three things have been bothering me recently with my universal fit iems.
ps
project86, 1964 ears response to my query about audiologists was a suggestion in Vancouver, which is odd. I live downtown Portland Oregon on the west side. Again, does anybody have a closer suggestion from experience? The few places I called didn't even answer the phone, which does not inspire confidence.
