I'm looking for suggestions for earphones that are comfortable when worn in bed. Specifically, comfortable when worn while laying on my side, with my head on a pillow. These would be used for listening to relaxation audios on an mp3 player to help me fall asleep. Sound quality is a consideration, of course, but comfort is more important. Wired earphones would be okay, though, wireless would be better if not too bulky or costly. I'd like to keep this under $150, but can go higher if necessary. Thanks in advance for your help.
