Open-back headphones like the AKG K7XX don't cause the issue for me, but then again if I crank them enough to drown out that one annoying coworker then everyone around me hears what I'm listening to and it can trigger my tinnitus. Damn. Maybe I need to apply for an office because I have a hearing-related disability. :-)
