For particularly good adaptation to a given hearing situation, an in-the-ear hearing device which has a housing with a channel in the housing that is designed as a through-opening for sound and air between the interior of the ear and the environment outside the ear, the channel is provided with a structural element for changing the size of the through-opening at at least one position. The structural element is a valve formed with electroactive material and the size of the through-opening is adjusted by application of a voltage to the valve.
