Chiming in late here, also had tinnitus with Bupropion, which remained for months even after I stopped taking it. Lowered my job performance because of it, never had any prior or posterior issues with other amphetamine-like medication (ritalin & vyvanse). I found relief in corticosteroids (combined pill of betametasone + chlorphenamine), which made the tinnitus disappear in a week. Now if it comes back it's very minor and I can ignore it, or go through a short course of medication again to make it go away for a couple of weeks.
Oh, and keep out of some noise cancelling headphones, they make it worse for some reason.
