When anyone wears a set of headphones for any length of time, an atmosphere develops inside which can only be described as steamy.
Today’s invention is a set of headphones containing a small airconditioning unit.
This would supply very low-speed, freshly humidified airflow to each of the ‘cans’ so that recording studio engineers and airline pilots etc would not be distracted by having sweaty, itchy ears.
The airflow would be driven around a loop by a very small, low-speed pump, carried on the belt of the user so that no audible noise would be introduced. This unit would also embody an electrically powered chiller/heater.
All of this equipment could be powered by plugging it into a standard jack of the type used to carry the audio signal.
