No you do not need an IQube to benefit from your personal frequencies. Simply by listening to your tones you should begin to notice subtle changes in you. But remember you need to listen for them to work:)
However if you wish to deepen the impact of your personal sound frequencies there is benefit from using an IQube technology. You can do this by experiencing a individual sound session with a local sound coach, experience a Group Sound Event or you can purchase one of our IQube technologies.
