The unstreaked tit-tyrant is 12 to 13 cm (4.7 to 5.1 in) long and weighs about 10 g (0.35 oz). The sexes have the same plumage. Adults of the nominate subspecies have a flattish black crest and a long tail. They have a black crown, a gray supercilium with white mottling, and a thin black stripe through the eye on a face that is otherwise gray with some white. Their upperparts are gray-brown with wide but very faint darker streaks. Their wings are fuscous. Their tail is gray-brown with whitish outer edges on the outermost pair of feathers. Voice: The unstreaked tit-tyrant's song is "a high, sputtering trill: tiii'reeeeeeee" and its calls are "high ti and tsee notes, and a short descending trill".
