Oh yeah, I get where you mean. For that bit I pull the skin up and away from the ear and bring the razor edge down carefully (horizontally) to the top of the ear. Then I bring the edge down again, but this time at an angle (heel lower than tip) to get that little bit (assuming left hand for left side, right hand for right side). Then I just go horizontally again using the last inch or so of the tip to go down beside the ear on the sideburn area.
