Query: Easy to start but one big problem

I had boughten this as a presnt to my step mother because she was always on the phone due to work. She loved it at first, it was very simple to connect to your phone but when we went to try it out it didnt work as well as I had hoped. I had called her from the home phone and there was mainly just a lot of static. I could here her but not very well. When she had handed me the bluetooth headset I could hear very well but the other person on the other end of the phone line heard the same static I had previously. We are still trying to fix it and might end up sending it back.
