I listen to radio and podcasts in bed a lot. To avoid disturbing Big Ears, I use one of these. One-ear-only suits me fine - don't need stereo and don't like something in the ear that's on the pillow. It's so light you don't know it's there and the gel in-ear loop means it just won't fall out. It says seven hours and, using just for listening (never phone calls or anything) I get well over seven hours. Charges back to full really quickly.
You can get them cheaper than this if hunt around Amazon or elsewhere.
