Patent abstract
In an example implementation, a self-cooling headset includes an ear cup to form an ear enclosure when placed over a user's ear. A first check valve on the ear cup is to open and release a volume of air from the ear enclosure when a positive pressure within the ear enclosure overcomes a cracking pressure of the first check valve. A second check valve on the ear cup is to open and admit a volume of air into the ear enclosure when a partial vacuum within the ear enclosure causes an external pressure to overcome a cracking pressure of the second check valve.
