It served three functions that I could see. First was that a strap on the top of it goes across the headphone band and snapped down on place to keep them from blowing off. The pilot also said they helped to hold your sunglasses in place if you turn your head and the wind catches the lens sideways and tries to pull them off. And finally it keeps any long hair from whipping around into you face. Our airspeed was around 80 mph or so the one time I looked at our gauges. The windscreen is pretty effective but I am tall and the top of my head was sticking out into the wind.
