90 percent of them dont seem to have much effect, but i found a few that seemed to put me in a super deep sleep... like an audio mind massage. pretty sure it was a 3hz delta state, with out any weird static noises mixed in. i find those static sounds somewhat annoying, but did find a pleasant one with nature sounds mixed in there.
