I’ve had my Widex Unique Fusion 220 for about 1-1/2 weeks and really like the Zen programs for help with tinnitus. Zen is the main reason I chose to wear hearing aids and the Widex brand. The fractal tones are great and I’ve been using it daily and have experienced a decrease in perceived ringing without the hearing aids when going to sleep. With the fractal tones on with a little noise I don’t notice ringing at all. Widex has a document that explains how to use the Zen programs to help habituate to the tinnitus. So far it’s working for me.
