^^^^ That is GREAT news! What make & model did you end up with? Yes, it does take practice to insert any kind of aids! I had SO MASTERED the ITC aids from decades of practice. In a pitch-black room, I could put those puppies in just by feel.
But now I have Oticon Opn RIEs, with the mic unit behind the ear and a dome at the end of a wire to insert into my ear canal. ACK it was impossible to do this without standing in front of a mirror, sweating profusely with agitation, for a good 4-6 weeks!
You mentioned that your transears HURT off and on, and this is not out of the ordinary at all. Part of that is fit (which I hope is a GOOD one for you), but part of it is just the correct insertion. When the aids are seated correctly, there should be NO pain - and you should be completely unaware that they’re in unless you make a face or somehow maneuver your ears in talking, etc.
I have finally figured out how to insert my domes for the greatest comfort: I have to pull down gently on my ear lobe, then carefully poke the double-domes into my ear canal so they fill the entire “doorway”. With my loss, a perfect seal and NO leakage is paramount. I can sort of do this without a mirror, but sometimes I get the receiver wedged against my ear canal and then … PAIN by day’s end.
Hope you continue to adapt to and enjoy your new aids. Just curious: how do you manage on the phone?
