I expect it would, although the shape and volume of the human ear cavity
varies enormously between individuals - so anything which relied heavily
on exact cavity dimensions for its performance would give rather
unpredictable results in practice even if it showed up well on
standardised tests.

Something which can affect the response of headphones is the poor seal
caused by locks of hair or spectacle frame sides spacing the ear pads
off the side of the head. Pressing the pads firmly onto the ears can
often make a noticeable difference due to the improved sealing, whereas
further pressure, which compresses the pads enough to decrease the
cavity volume, has much less effect.


Likely to affect lower frequencies, rather than high.
