I have owned 4 sets of hearing aids over the past 20 years. All from different manufacturers. What I learned is this: be specific on what you need - quiet environment or church choir singing or phone calls that you hear via the hearing aids. This will point you to type and manufacturer, I now have a set that connects to an App on my iPhone so I can modify some parameters for various situations. Final note: after 25 years my tinnitus is still loud and present. Nothing helps.
