Sorry, you're kidding, right? I have problems going to sleep, even with medication and a sound conditioner, there is no way I could fall asleep with earplugs or (GASP) Headphones on my head?
I Have tried having a small bluetooth device plugged into my phone, but if I turn off the screen (the light) stops the sound.
I am still working on it my friend.
