Hi Eva. I have suffered from tinnitus for nearly 10 years. I got an sinus and ear infection and the ringing has been unbearable lately. I am desperate to find a cure. I am not sure if they worked yet but I don't hear any ringing at the moment. Maybe it worked!! Would you be willing to send me the sound files via email? Or can you posted them here for download. I am not sure you'll even read this since it's been four years but I hope so.
