I also recommend hemi-sync. Binaurals take some patience but I believe they can work. I have had intense sensations and CEV's associated with hypnagogia while listening to binaural beats before sleeping. One time I had a brief out of body experience. Another time I hallucinated that people were screaming (kinda scary but interesting nonetheless). And one time I could control how large my body felt, like I could expand infinitely and contract to a single point. There have also been other indescribable sensations.

You have to wear headphones if you want to do it. You must make sure the correct speaker is in the correct ear. You must know about "mind awake, body asleep" and practice it. You must have patience and discipline. Binaural beats are basically meditation aids.
