A portable headset for equalizing air pressure across the tympanic membrane of a user's ears. The device comprises two earpieces secured at opposing ends of a headband. The earpieces are cup-shaped housings containing a fan and a speaker. A mesh screen covers the open portion of the housing to protect the user's ear from contact with the fan blades. Additionally, a cushion is disposed along the perimeter of the housing to buffer the user's ear from the device. When the device is turned on, the fans rotate and air is pushed into or pulled out of the ear canals. Rate of rotation and direction of rotation are controlled via at least one pressurization selection dial. Thus the air pressure can be changed as a plane ascends or descends through the atmosphere. |
