Human Factors
I was flying a helicopter near the south end of the ZZZ Class C airspace. I was flying over the ridgeline at about 1;700 feet when the Tower advised of Aircraft Y east abound approaching my location. At that point Aircraft Y was about 500 feet above us and a mile west of our location. ATC tower also told the other aircraft of our location and he informed the tower that he had visual contact with us. I immediately descended near the ridgeline (to about 1;500 feet MSL) and turned south east away from the approaching aircraft. I saw him pass behind me. As I turned to look for him to my left I did not see him appear. At that moment my right seat observer saw him back on our right side (west) and he was descending and passing below us. At this point I was near a well known landmark (just outside the airport airspace) and was at 500 feet AGL. Aircraft Y passed below me and continued east. Tower did not give Aircraft Y any vectors to avoid conflict even after I turned away from the traffic. To my knowledge; the pilot of Aircraft Y was still in radio contact with the tower. Further; Aircraft Y flew through a TFR area about 45 minutes after this incident.
