Hey PaulC,
That is exactly what my Audi did: she cut transversely a few molds including Widex tulip mold and Otticons’ round Dome molds.
the results of those tests were:
- an insignificant reduction of feedback
- the form fit to my ears was so complete it felt like like custom molds without vents, and the occlusion was a bother.
I ended up using the uncut open round domes from widex.
The feedback occurs most often while sitting in my car seat. I pushed back the headrest which helped and I am accepting annoyance, but the feedback is there.
Also my Audi shortened the wire length which helped slightly but unfortunately the new tighter wire length doesn’t follow the track of the old wire and I miss the old ones.
I think I’ll spring for custom molds and a longer wire. My next appointment is scheduled for December but I just may the queue.
Thanks for your input
