This is pretty cool, but unfortunately I have somatic tinnitus, so this doesn't work as well. The frequency/tone is very dynamic with my version of tinnitus and I can even change it by moving or massaging my neck (especially at the base of my skull) in certain ways.

I have found doing the Alexander Technique helps me quite a bit with the tinnitus.
