@FrostedFake: Yeah man, I used to listen to masked subliminals with speakers on either side of my bed, very low volume and for whatever reason when I woke up in the night might ears would ring momentarily. Even happened with the ultrasonics (although perhaps not as suprising). Bottom line, when you use the ultrasonics you can put them at a loooooow volume on your phone/ipod/whatever and you'll still get benefits.
