Dynamic head tracking restores externalized sound localization in binaural reproduction.

Evidence

Head movements have long been assumed to be important to satisfactory externalization in binaural headphone reproduction (Toole, 1970). The brain protests when the musicians and the performance venue move with the head. But mismatched HRTFs are a logical contributing factor to the perceptual error. — Toole, Floyd E, Sound reproduction- the acoustics and…, 290 (#corroborates, via linked claim)
