I've just given it a try, but I'm not sure it worked properly for me. The resulting EQ curve made everything sound extremely thin. From EQing music, I know how boosting higher frequencies can make it feel closer/more present, and the idea of compensating for hearing loss sounded good to me, but here the high frequencies turned out painfully loud, and the bass (and even mid) frequencies almost non-existent. Not sure what went wrong.
