Hypnosis/Relaxation Sounds/Procedure

I’ve noticed that people seem to have pretty good results using YouTube sleep videos. My question is how do you listen to them? With headphones? On a phone next to your head? I don’t really want to sleep with my phone radiating next to my head all night, and I pretty sure sleeping with headphones will be impossible. Plus, YouTube won’t play with the screen closed and I don’t want light from my phone shining all night. Trying to figure out how y’all are doing this.

I might just get a CD. Any suggestions???
