In our modern world, more and more people rely on their smartphones for communication. In this way, they are able to stay in touch with friends and family even if they are thousands of miles away. Unfortunately, this also means that they cannot use their hearing to the full extent of their potential.

If you are one of these people, you might want to consider using a hearing aid with a microphone on your smartphone. With a microphone, you can record your voice and use it to text or talk to others. The problem is that you might not be able to hear the other person's voice. This is because your phone's microphone is usually located somewhere in the smartphone and the microphone is not very sensitive.
