An ear phone assembly is provided for use with a hearing screening instrument to test infants for hearing impairments. The ear phone includes a generally D-shaped reusable cover including a back wall having a perimeter, a side wall extending from the perimeter to define a cavity for receiving an infant's ear, a port in the cover to receive and support a transducer, and a generally D-shaped disposable element that is adhesive coated on two sides to be secured to the cover and to the patient's head. The cover may have a notch located along the perimeter of the re-usable body for removing the disposable element. A liner is used to cover the disposable element adhesive sides to protect them from contamination during packaging and prior to use. The disposable element may have a die cut so that a portion of it can be removed to make the ear phone adjustable for infants with large ears. The ear phone is low in cost and capable of being used with any conventional hearing screening equipment.
