Metacognition has emerged as one of the most preeminent constructs of cognitive research. The core premise of embracing metacognition lies in its underlying potential to regulate, monitor, and plan the process of learning. Metacognitively aware learners empower their zealous in their pursuits of exhibiting more accomplished performance and guide their attempts towards higher proficiency gains in language learning. In addition, encouraging role of metacognition leads to witnessing sufficiently sophisticated advanced-level L2 listening proficiency. This paper attempts to explore whether metacognition has the potential power to bring in the ingredients for notable improvement in listening success. It would appear that metacognition has a number of concrete effects for the occurrence of high levels of L2 listening mastery.
