I prefer listening to audiobooks (novels) for going to sleep. The app I use on my tablet has a sleep timer with a chime sound to signal you when it’s about to turn off. Shake the tablet briefly to extend the timer. I use cheap wired earbuds, or earbud actually because I cut off one of the buds and listen with the ear that isn’t facing the pillow. Occasionally I’ll get up and out of bed dragging my tablet with me.
