My AN ear is my left ear, so I can hear the passengers in my car, but I cannot hear the person at the drive-through window unless I wear my bicross hearing aids. As Bonnie said, they are not perfect, but they have helped me enough that I continue to wear them. The bicross hearing aids will not be like your regular hearing, but the question is, will they give you enough hearing assistance that they are worth the expense. For me, that answer is yes -- but then my work involves hearing what others are saying, usually in a fairly quiet setting. I am not usually in noisy environments which are much more difficult for me, even with the setting on my cross system for noisy environments.
As Bonnie said, you might want to take advantage of the trial period. And, if you have issues with it, you can speak with your audiologist about adjusting the settings of the hearing aids. And then, if they still don't work, return them during the free trial period at no cost to you.
Best wishes!
