When I need to go to work early I need both my mobile phones (my private one and the company phone) set to maximum volume and a normal alarm clock just in case...

My brain is tuned to it. I regularly sleep through my wife's alarm and routine (she gets up a little bit before I do), but I've only slept through my own 48G alarm clock a couple times. And fortunately not by much!
