I went with standard domes but it took a second visit to get the size right since they take time to conform to your ears. Custom molds are another option but they told it I would get a more plugged up feeling so I stay with a more open dome unless really needed. Also there is some time for adapting to any changes in settings. They also bump up the gain with each visit to reach target levels. A big jump might be too much. I think there is room for optimizing the whole process but anything medical related tends to move slowly. I still find the phone app a little slow and cumbersome. And switching between bluetooth devices is a pain. I wish Apple and Google would put more effort in improving that aspect.
