I like to go to sleep listening to music or lectures, I don't want to annoy my flatmates by using the stereo so the challenge is to create something that allows me to lie on a pillow with my head on its side and listen to whatever.  Before building soft headphones or a bed speaker, I am going to try and sew a supplimentary pillow with a hole for headphones and extra support around the ear and see if I can comfortably fall asleep with headphones on.
