If you’re going to find a shop for them locally, I would check the ASAs website. Shops who spend the time and effort to become members of the ASA are typicality some of the best shops as far as technical knowledge, fair pricing, and honesty.
I have a student that wears Bluetooth hearing aids, other students phones connect to them all the time. Students down the hall will start playing music, and it will take over her hearing aids. Turning all of our Bluetooth to off fixed the problem. None of the devices that connected to her hearing aids was ever paired, they just connected.
