Earphones fit perfectly in your ear leaving no gaps which prevent airflow and shuts out all the unnecessary, annoying outside noise but they also come with annoying wires that get in the way of everything.
How nice would it be having the benefit of earphones without having to deal with all those wires?
Having a pair of wireless earphones is much better and useful. You will use them while sitting in a crowded place or when exercising or walking your dog. Or just talking without the wire mess surrounding you.
