More attuned to absence (the voices on the headset) than presence (the pedestrians that passed me).
For instance, their children judged sentences in a lab setting, listening to them through headsets.
But no matter how many monitors, headsets and leads were on display in these rooms, the medium in which teachers and pupils worked was sound.
I'm sure this was caused by the physical act of walking, which invites you to merge your experience, your narrative, with those of the stories you hear on the headset.
I was told that during the summer a flight deck officer's headset volume control broke.
The headset was mended and put back in service.
As headsets take such a low priority nowadays, many patients are encouraged to bring their own headsets and transistor radios with them into hospital.
Often people visiting hospitals ask whether they can tune in to the hospital radio station on their own headsets.
