I am getting used to my new molds. They are pretty tight and caused some pain at first. Maybe my ear canals are stretching but the molds are getting much more comfortable.
I noticed some occlusion early on. The software has occlusion control that I adjusted up some and now occlusion isn’t an issue.
The range of sound in all my hearable frequencies has vastly improved. Music is actually pretty good again. I have the Compilot2 which is absolutely fantastic for TV and phone calls. I can now understand YouTube videos.
Feedback has never really been an issue with the Phonak aids I have used. I hope your new molds fix you up.
