SM Entertainment Girl Group Main Vocal Faces Intense Criticism For Singing Skills

Hearts2Hearts member Carmen is drawing mixed reactions online following the group’s recent appearance on Knowing Bros.

After clips from the broadcast began circulating on social media, some netizens criticized the rookie idol’s live singing, arguing that her vocals sounded “off from the first note.”

Others called her out for her bad technique. They pointed out that while her natural range allows her to hit high notes, her technique was “bad.”

Even a fellow Indonesian felt inclined to point out how bad she was.

Sometimes, high notes are not equivalent to good singing.

When ppl will learn that screen or high notes doesn’t means a good vocal? quantity is not quality she is completely out of tune

The discussion quickly spread across online communities, with some viewers expressing disappointment given that Hearts2Hearts is SM Entertainment’s newest girl group.

Others defended Carmen, pointing out that this might be an isolated mistake.
