A follow-up. Had my regular hearing checkup with the audiologist today and told her what I did the APP2's and she was quite excited as she was aware of what Apple is doing. She did an actual test with the APP2's with the current state of transparency and available settings, the same test she did with my hearing aids. She said they did quite well, though not as good as my high-end hearing aids. She thinks these could be a real game changer.
