Best way I manage mine is for example at work I leave a radio on very softly. Kinda gives enough background noise to help me not have ringing as bad.

Actually had a discussion with my neuro the other day. Said the ear drops and stuff you might see commercials for are just companies trying to get your money and they do nothing. I can't remember exact wording but my neuro said according to the AMA theres really nothing for fixing tinnitus.
