The husky, sassy vocals have brought a lot of attention to how similar these two idols sound! And Sojung even performs Lee Hi's debut track here, sounding just like her! They even have a similar vibe in looks. Lookin' chic, girls!

Onew was much beloved for his extremely unique voice that is immensely soothing. While Hyuk doesn't sound exactly the same, he has that same softness to his deep voice. Their voices are so hard to really describe, but everyone just knows. They can melt hearts.

They have very lighthearted voices that are perfect for indie-inspired songs and soothing acoustic performances.

Shannon can't be forgotten! She wowed the audience on 'Hidden Singer' for her perfect imitation of IU's voice and singing style.

When people noted maknae Taemin's impressive improval in vocals, they also noted that he was sounding strikingly more and more like the group's main vocalist Jonghyun! The Michael Jackson sort of feel in their pitchy vocals is alike. Jonghyun must have rubbed off on Taemin.

Their voices are interchangeable at the chorus - just seamlessly going from one to the other. They do that pitchy thing at the end the same way, too! It's their signature sound.

They both have the soulful singing with a tinge of nasal and a spoonful of husk. They emotionally sing their hearts out in similar ways. After all, MBLAQ was supposed to be the boy group version of Rain of sorts, so makes sense the main vocalist sounds like him!

A lot of people say the sisters sound similar. While I agree they both have a soft, angelic sound with a slightly nasal tone, Krystal's seems a bit deeper, leaning toward alto while Jessica is a clear soprano. Still, when singing softer and gentler or higher-pitched songs, the similarity is definitely there.

They both have incredibly deep voices that are perfect for charismatic rapping! P.O even seems like a mini-T.O.P in appearance and derp somewhat. He mostly grabbed attention for giving off a T.O.P vibe when rapping.

A lot of people seem to be saying the two singers sound alike. Yoo Yeon Jung was a former SM trainee so went through a similar training as Taeyeon; not only that, they have a similar voice, especially when hitting higher notes. You can hear that in the ad-libs above.
