We present an open DIY platform for augmented reality audio in the form of ultralight acoustically transparent headphones and a minimalist hardware platform serving as USB audio interface, signal conditioner, and head tracker. We outline the open hardware and electronics designs to permit reproduction, extension, or customiza-tion. Furthermore, we show the results of measurements that evaluate passive transparency, variation in the headphone transfer function (HpTF) due to repositioning, as well as tracking latency and maximal output of the headtracker/audio device. This design has the potential to promote research and development applications in audio augmented reality at low costs and size.
