I want to listen to music or hypnosis through ear buds but?

I cant do it while I sleep because I fall asleep and the cord gets wrapped around me. I am wondering if their are wireless earbuds. Like for instance, I plug something into the headphone jack of my iPhone, 4 feet away and put earbuds in my ear with no cords that are good quality sound. This way I am not strangled by a cord, the buds wont fall out my ears and I can sleep somewhat comfortably with them in. Do they make those? Could you provide links. I searched for some but I only found bluetooth headphones that have cords.
