Current wireless headphones typically use infrared, radio spectrum, or Bluetooth, all of which are prone to casual disruption. Sony aims to change that with their body-wired headphone patent application. Their headphones would basically use your own body to carry the music up to the headphones, via a few millionths of an amp that turns you into a human capacitor. The resulting music would be 48kps quality, which according to Sony is plenty. (Could someone explain how that’s plenty?)
