My customers kept complaining that they kept hearing static each time I spoke

I have a hard time hearing on my home phone

I was able to use it 2 times as the headset wire connection broke so it now usless to me as i can not talk on it as no one can hear me

It worked fine for a couple months then the people she was talking to started having a hard time hearing

And I do not like the time counter does not count in hours, minute and seconds
