I've tried many binaural beats but many of them have annoying music which puts ne off. I've used your videos to fall asleep many times and can say they work well. I'm not an expert in binaural beats and have heard that they put you in a relaxed brain state and I never really noticed If it was me or the audio responsible for it.
In my experience, it's both! The listener has to be "cooperative" to a certain degree -- you can certainly resist the effects if you aren't fully receptive.
