Mine is like an inverted bell curve. The mid range is at the bottom of the 'U' shaped curve so it is missing in a diminishing way. The biggest problem is in noisy places. I've always been pretty good at contextual understanding so if I hear the whole sentence or paragraph I can fill in a lost word. The expensive models have built in Bluetooth so my iPhone and anything else Bluetooth would be wireless. It's been a year so I need to get them. Both ears are the same, interestingly enough. There's an app for that! Iphone had an app called Sound Check. I downloaded it and remarkably the results were the same as the hearing test. It's good for those who want to know but font want to go get it checked. There are two negative aspects to hearing aids, first is the cost, second is vanity or stigma.
