I've been looking at Headphones to use with the Life Response Frequencies. Wondering what range of Frequency i will need. For instance, is something between 16 - 23000 adequate.
I realise they should not have Noise Cancelling feature. I think what i need to know is what DO i need for the optimum benefit from the programme.
I don't want to spend more than necessary, but equally don't want to buy something that lessens the effect of the material.
i think the lowest frequency the human ear is somewhere around 8-13 hz. the ones i have start at 20 and seem to work just fine, they cost me about $10. imo what u have should work just fine.
These ones are Great
