IU’s timbre is very unique, her voice is very layered, and has a very strong appeal. Whether singing a cappella or singing in a concert, her voice is as clear as a CD, so there is a "walking CD" Such a title. IU has her own singing style, and there are many delicate things in her singing that others cannot imitate. She can give her best in her familiar vocal range and do what she is best at. IU's singing skills are also recognized by professionals, with a very wide vocal range and first-class intonation. People in Korea will tell you

If you name just one idol, Koreans will probably not know that BTS is included. But no one doesn’t know IU. I don't know what the boundaries of the Korean entertainment industry are. Anyway, she can't be considered an idol now. With such a high national popularity, she is more like a singer, or a star in the traditional sense. And when most Koreans talk about IU, they will definitely talk about her songs. You will know what level she is, a national singer. And normal people who pay attention to those rumors don't care at all. In their impression, they only have national singer IU, and IU's songs and IU's loyalty. Zhihu is quite amazing. I think people with this hot knowledge should still achieve *** knowledge. No one will fool IU unless she is later exposed to have committed a crime or something. Chaos in the music industry

After SBS’s “I Want to Know the Truth” aired content about fake music, IU expressed her stance on fake music through SNS. In the screenshot of the show taken by IU, there is also text that reads: Please stop using audio robots. In just one sentence, IU’s bitterness can be completely understood! Sunmi also followed in IU's footsteps and took a clip of the host's speech from SBS's "I Want to Know the Truth" on her SNS and posted a big wordless emoticon, feeling quite helpless about the chaos in the music industry. Iu is simply not too good-looking

Iu can be said to have the kind of appearance that appeals to straight men. She cannot be said to be the most beautiful in the entertainment industry where there are so many beauties in Korea, but It can be said that he is the most comfortable looking one. Iu's style can be salty or sweet, cute enough to make you think she is 18 years old, or sexy but not coquettish.

As a singer, I think Iu has really done her best at her age. She writes lyrics, composes and produces albums herself, and is a very talented singer-songwriter.

IU is very famous for its three-stage treble. The progressive treble is simply not perfect. But this is not her unique technique. She said in an interview that "the three-section high note is actually just something to practice. It is a very unique singing method, not her own unique skill."
