Noise Cancelling Headphones for the Hard of Hearing Girl...Probably Not a Good Idea

I have these noise cancelling headphones that I love. They go into my ear so I can't fit them in there with my hearing aids and naturally the hearing aids have to go. Yesterday I was getting out of my car and a car was driving pass when the driver stopped and backed up. I thought she wanted my spot until I turned and saw that someone had gotten into the car beside mine and was backing out. I had not heard her at all; I didn't hear her get into the car or start the car. And then today I was walking and almost walked in front of a car. I didn't hear it coming. That kind of made me nervous. Maybe noice cancelling headphones are the best for me since I can't hear anyway. But I really like them; I like just being able to hear my music and none of the other noises. I'll just have to be more vigilant and look around to make sure I know what's going on around me. I usually do but my mind has been somewhere else this week.
