Hey Pinks. Sorry to hear that you are struggling with the unit. Do try to maybe lower the stimulus intensity or the sound depending on what feels better. Try using it once per day or doing both sessions one after another. I have been through the same things with the unit and do also have some high pitch tinnitus but it´s so much better than what I had before.My tinnitus has still been elevated, but this could also be due to my clogged ear wax buildup that occurred quite suddenly three days ago. I got it out today, but my ears still feel irritated from the whole ordeal.
I want to say it calmed down a little from stopping the use of Lenire, but the very high pitch tone it caused is still present as I write this.
