Abstract
In an example implementation, a self-cooling headset includes an ear cup to form an ear enclosure volume and a control volume. The headset also includes an intake valve to open and admit air from the ear enclosure volume into the control volume when a negative pressure is generated within the control volume, and an exhaust valve to open and release air from the control volume into the ambient environment when a positive pressure is generated within the control volume.
