Exactly, interestingly I remember Michael Abrash recounting when he was demoed personalized HRTF for the first time. They put headphones on him and sat him in a chair. A person started walking around him in circles holding a small speaker. But it was obviously a trick, the sound didn't come from the speaker but the headphones - but according to his account it was indistinguishable from the real thing. He was astounded when the person walking around him stopped but the audio remained circling around him. Personalized HRTF is a game changer.
