At last a solution to the annoying problem of tangled headphone cords! These headphone cords stay tidily in their sleeve until you pull them out to use them - and only as far as necessary so there's no excess cord length to catch on things. Then when you are ready to put them away, a gentle tug pulls them back safely into the sleeve. They come with several sizes of earbuds to comfortably fit anyone's ears. I recommend them highly.
