I don't remember the exact model that I had of the WIDEX tinnitus devices. I originally tried TRT twice, and used different models for the masking.
The first model that I had has some white noise sounds, and then some chime sounds. I didn't really find this model helpful.
The second model that I had, had 5 or 6 different white noise settings and I found it much more helpful. That model costed I believe approx. 3,000 CDN. The clinician was very good and extremely helpful, however at the time I was living far away from the clinic and was having issues with my reactive tinnitus. So I decided to return them.
In the end, maybe one day I may look at going back to these options. But I can attest that the second model of the WIDEX masking devices helped me habituate to my tinnitus a bit better.
