Audio rendering in AR/VR applications is typically combined with acoustically transparent headphones to facilitate immersion. When developing such headphones today, the challenge is not the absence of signal processing capacity, anymore. Consequently, hardware development can focus on the most essential electro-acoustic properties. This allows to consider radical acoustic headphone designs without sacrificing audio quality. We present an ultralight circumaural open headphones with ear cups based on bionic design, and their step-by-step tuning. The prototype is open access, 3D-printable, and avoids any excess material. Hereby excellent acoustic transparency is accomplished and verified in comparative measurements with industry-standard headphones.
