Frequency Response

[CouldBeJesusX]

What is the recommended frequency response for I-doser? I seen on a description of one of the doses that it brings you down to .5hz. My current headphones have a range of 18-21,000 hz. My other headphones are Bose in-ear headphones. I can't find out anywhere what the frequency response on those is. I might also lose sound quality from them at the moment anyway. I have to twist the end of the headphones till I get sound in my left ear.

Dont worry about frequency response, the human ear is only capable of hearing between 20 - 20,000hz anyway.

The way they get it down to that low is by.. lets say you want a 5hz tone. Then they play a 100hz in your right ear and 105 in your left leaving you with a 5hz tone.
