This year I went to the hearing aid doctor because I can't hear my wife.
The doctor said my left ear is dead above 2k Hz because I am a right handed rifle shooter.
I paid $6k.
It turns out I can't hear the wife with the hearing aid either. She is low talker that speaks while clanging thing together right on the key words.
I have not worn the hearing aid again since the first month. Waste of money.
