I have not tried the binaural sound but I do have a few recording of singing that will help me fall asleep. Sometimes, I need a bit out routine visual stimulation to focus on so my visual processing sort of fades to black. If I close my eyes but they are still jumping around, it will take a long time to get to sleep.

As I have mentioned before, I need to reduce all tactile stimulation. Soft pajamas, comfortable mattress and pillow, I even do best with something soft touching my right cheek.

We each need to do as you did and experiment with different techniques. Glad to hear you found one that works.
