Noun: A sex technique, where a recipient takes a seat in a chair while two friendly gents stick their penises in the recipient's ear to the best of their abilities. The gentlemen administering their penises must hold hands above the recipient to complete the "headphone" shape. The recipient usually wears a warm smile and strokes the penises, but this can vary depending on the tone of the encounter. The Headphone is similar to the "Eiffel Tower," in a sense, but involves a remarkably different feeling.
