Many of our idols pack some powerful vocals that we can't help but get lost in. However, among the many K-Pop groups and lead vocalists out there, there are other members who are really hiding some powerful vocals we wouldn't expect and who unfortunately get lost in the crowd! Turn up your volume and browse these 10 idols who will blow your mind with their unexpectedly more-than-perfect voices!

This cover of "Fools" will have you never listening to the original again! BTS' Jungkook and Rap Monster really blew fans out of the water, as their dreamy voices made this melody perfection. The deeply toned voice of Rap Monster came as a huge surprise in this track as he sang more than rapped.

EXID has gained huge popularity, and many are recognizing their vocal talent, especially Solji's. However, if you were a fan before the "Up & Down" hype, you would know about DASONI, the sub-unit group consisting of vocals Hani and Solji. Hani definitely stunned the crowd as she reigned supreme on this episode of 'Mask King' with her husky, jazzy vocals, which people weren't expecting because she's known more for her dancing and variety skills.

BTOB's Minhyuk definitely lays on the charm with his smooth-as-butter vocals. With BTOB's songs being more upbeat and rowdy, it is more of a delightful change to see Minhyuk's precious vocals highlighted in beautiful ballads.

Every fan, including the hosts, had to take a step back when INFINITE's rapper Dongwoo stood on stage and surprised everyone with his delightful vocals! He is recognized for his smooth style and strong rapping skills but he proved he has a soft voice perfect for any beautiful ballad on 'The Beatles Code 2.'

Girl's Day's Sojin has a very special voice, and in the beginning it was still being crafted. Originally having a rough debut, Girl's Day really turned things around and mastered their vocals! Sojin put the haters back in their place with her beautiful song on 'Healing Camp' and growing presence in OSTs.

The boys of CNBLUE definitely boast some sweet voices, but Jungshin is quite the singer despite being known as the bassist of the group, and he lets the world know with his own solo stage! The song "I Want To Fall In Love" really emphasizes his gentle voice; especially take note of his effortless high notes and elongated notes.

The handsome rapper does more than drop some sick lines along with a sick beat-- he is a talented vocalist, too! T.O.P. showed off his solo abilities with the 'The Secret Message' OST "Hello Haruka." Not only is his voice heart-melting but also he can definitely carry a note.

Probably one of the most hidden gems in the K-Pop industry is f(x)'s Amber! She has a lot of serious swag and has owned the girl group rap game for some time; however, she was holding back some seriously pretty vocals that she dropped like a bomb on 'Radio Star.' Although never given the chance to showcase this skill in f(x), there's no doubt she has it!

Tahiti's Jerry is quite the powerhouse among K-Pop idols! She really mastered her pronunciation and vocal range as she flawlessly covered Alicia Key's "Girl On Fire." She holds the notes well and transitions effortlessly in each chorus and verse, but not a lot of people know this!

Although many people are won over by TEEN TOP's Niel's outstanding vocals, member Chunji has quite the voice, too! While we do get to hear his beautiful voice in various songs, fans definitely experience his vocal power as he belts out wondrous notes to the beautiful balled "On A Night Just Like Tonight" on 'Mask King.'
