Podcasts have become a pervasive and easy-to-access input for language learning that may improve both form and meaning aspects of language. This study attempted to investigate some unknown impacts of the autonomous use of podcasts through a metacognitive intervention on 12 adult language learners’ listening comprehension with an exploratory approach and using a questionnaire, learners’ journals, and semi-structured interviews. The results suggest that autonomous language learners may benefit from multiple advantages of utilizing extensive listening input such as podcasts. Moreover, the learners have a positive attitude toward learning listening with metacognitive strategies and asserted that they aided them to be independent listeners. This study underscores the effectiveness of applying technology-based listening learning in an EFL context where many learners are devoid of sufficient authentic and comprehensible input.
