What do you think of a person going out shopping with headphones?

I think if a person wears this kind of earphone in the street, it proves that he is a cool person, and there is nothing to say when to wear it, because it's none of your business if people don't wear it. Why do you care so much? You must be careful of people wearing headphones in the street.
