Your post is really helpful. I’ve felt the same way for several years.
While my new practitioner has made great headway I need help too.
I’ve been wearing Jabra EP 10s for 2.5 years. The only time I get feedback is when they were adjusted incorrectly. If your supplier can’t adjust your Vivias, returning them is the best course of action, but it may be te supplier, not the aids themselves.
I would try signia pure charge and go bct 7ix
