He is often teased for his head voice and exaggerated vibrato since he is the vocalist of the band Buzz but he is the worst dancer among the brothers because of his not-synched body rhythm. He is known for his lack of knowledge of business entertainment, especially names, so they make jokes that a celebrity is really famous if Min Kyung-hun knows about him/her. Many celebrities, mostly idols, ask him if he knows who they are. But he is the most skillful among the members thanks to his training of martial arts since elementary school.
