Given to Francis by Bill Vernon, these "Realistic" headphones were supposedly the only currently available that would help Francis to acclimate to the three-dimensional world by surrounding his ears with the sounds of three-dimensional life. Through these headphones, Francis listened to hours of ambient field recordings while testing Cycloptical devices, with Bill noting when Francis' perceptions were aided or hindered by the sound in the headphones.
It has been noted that the findings that came from these headphones may be tainted by the fact that they were blown out after Francis plugged them into a stereo and placed them over his knee and at full volume so he could better hear.
