Drop Discusses Driver Geometry on Axel Grell's OAE1 Signature Headphones
Everyone perceives sound differently. Your ear is not like a measuring microphone. Because of this, it's important to understand how sound is perceived and what factors influence that perception. In creating the OAE1 signature with Axel Grell, we studied how sound is perceived. This premise drove the unique geometry and driver placement for the OAE1 Signature headphones. Since our ears, with all their unique characteristics, act as a natural equalizer to all that we hear, it makes sense that headphones should do more to use the structure of the pinna to guide soundwaves into the ear canal.
To achieve this effect, the transducers are placed much further forward and angled back towards the ear. By positioning the transducer further out and away it enables the soundwaves to fully encompass the pinna (the external part of the ear), allowing for an increase in spectral information and a more natural sound field for the listener. By contrast, the majority of headphones on the market are much closer to the ear and positioned perpendicular to the opening of the canal which bypasses much of the pinna's structure (and therefore the natural sound-shaping function of the ear itself).
