In order to reproduce audio over headphones as in-
tended, it is essential to have well-defined and con-
sistent references of how headphones should sound.
With the aim of stereo reproduction in mind, the field
has established a de-facto reference target curve called
the Harman Target Curve to which headphone transfer
functions are commonly compared. This contribution
questions if the same target curve is suitable when used
for the reproduction of spatial audio. First, the ori-
gins the Harman Curve are revisited; it is motivated by
the frequency response of loudspeaker playback in a
specific listening room. The necessary measurement
procedures are described in detail. Then, the paper
discusses the applicability of existing targets to spa-
tial audio. Therein, it is possible to embed convincing
spatial room information directly into the production,
thereby calling into question the motivation for incor-
porating a listening room in the headphone target. The
paper concludes with a listening experiment that com-
pares the preference of different target curves for both
spatial audio and stereo
