My mother has a Parkinson's type disease, which has impacted her speech, making it hard for my dad to hear what she is saying. I was thinking about using the Sena Expand so they can better communicate in the car, in supermarkets, when they are watching TV, etc. I have downloaded the manual, and can't see where you could adjust the microphone sensitivity. Can you do this? She speaks very quietly hence my concern about adjusting.
