The one who listens to a Surah is not regarded as having read it. So, if a person wants the reward of reading Surat Al-Kahf on Friday, then he has to read it and it is not enough just to listen to it.

No one knows exactly when he will die, or in what land he will die. There are no specific signs by which a person may know that his death and the end of his life are approaching. But there are some signs which may indicate that the end of a person’s life is approaching, such as if he suffers a severe sickness from which people hardly ever recover.
