Thank you very much for your detailed explanation . You are really expert in this field, you know so many things about this matter. I really appreciate your effort and time to help me and other people.
Thank you for your kind comments @Marko Nakovski
I have had tinnitus a long time and acquired a lot of experience but do not consider myself an expert in this field because it is very complex. When I first got this condition twenty two years ago, I was helped in a tinnitus forum similar to this one by people that had it for many years and coped. Their help and wise counsel was invaluable, for I was very scared for my future and thought my life was over. It is my purpose to try and help people affected with tinnitus in anyway possible.
You should be able to order the Oasis S-650 or another one of their models from Amazon and get it shipped to your part of the world. If you are having difficulty, then contact me and I'm sure something can be worked out.
Take care
Michael
