Binaural recordings capture natural direction cues only when ears match the listener

Evidence

Binaural techniques are loosely defined to be methods that aim to reproduce accurately ear canal signals recorded in a real acoustic scenario with a real subject, or to reproduce ear canal signals which would occur in a virtual world. This is done by recording sound from ear canals or by utilizing measured or modelled head-related transfer functions (HRTFs) and acoustic modelling of listening spaces. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1916 (#expands, via linked claim)
