Having spearheaded some of the most iconic designs at Sennheiser including the HD650 and HD800, Axel brings a wealth of engineering expertise to this new open-back headphone. We dive deep into his unique headphone design philosophy, specifically the Front-sided Sound Field Modulation (FSFM). Axel explains how positioning the 40mm bio-cellulose dynamic drivers at a forward-facing angle minimizes the "in-head" effect, creating a soundstage that mimics high-end loudspeakers. We explore the technical nuances of tonal balance, imaging, and why the OAE2 uses a precision stainless-steel mesh for superior acoustic damping. Whether you're an audiophile chasing the ultimate high-fidelity experience or a music lover curious about the future of German engineering, this conversation reveals the meticulous detail required to achieve true transparency and natural sound. *affiliate links help support the channel - thank you!
