Top 10 Best K-Pop Group Sub-Units

Obviously, it's TTS. They had the best physical sales and very stable digital performance, with a mega hit (Twinkle) for their debut. Please anticipate more promotions from them before the year ends!

They have great vocals and an almost flawless discography (keyword: almost - sorry, Holler, no one thought you deserved to be the title track). And, um, visuals anyone? Plus, they're from the legendary SNSD, with an unbeatable legacy as a KPOP group that pioneered the Hallyu wave.

Other subunits are great, but TTS is THE subunit.

TaeTiSeo is and will always be the best. They have perfect vocal harmonization. Not only is their music awesome, but their members are also the best. Taeyeon is cute, Tiffany is sexy, and Seohyun is innocent. They are the perfect combination ever formed in our generation.

They are so talented and amazing. I also love EXO-M, so this was a really hard choice, but my vote goes to EXO-K. My bias is Park Chanyeol.

They are amazing, but I wish that EXO's Chinese members got the same treatment as the Korean ones.

No doubt, this is the best KPOP subunit! Catallena was a BIG hit, and their dance practice video is one of the most-watched dance practice MVs on YouTube. Magic Girl is one of their biggest hits too. Bangkok City is so catchy! Shanghai Romance is so cute, and the dancing is adorable too. Aing is one of my favorite songs from them. Their recent song, My Copycat, has one of the best concepts ever! They always come up with the best concepts.

I love how OC is able to make saccharine cuteness work really well. Their songs are always catchy, with nice and easy-to-follow dance routines (which must be a relief for the members compared to their much more difficult choreography in After School). They are all great singers. OC got me into KPOP and will always be my #1 bias.

SISTAR has sexy and cute songs, while SISTAR19 has even sexier tracks. Hyorin and Bora's voices go so well together. Hyorin's singing and Bora's rapping complement each other, allowing them to produce great music.

Although there are only two members in the sub-group, SISTAR19 can still pull off fantastic songs and dance routines. They are also able to showcase their sexy concept and still do so well. SISTAR19 fighting!

The two members complement each other really well. Hyorin's singing and Bora's rap just go hand in hand, and their songs are always awesome.

K.R.Y is a beautiful mix of three amazing voices! Years of work, effort, and learning are evident in every song. Kyuhyun, Ryeowook, and Yesung truly are some of the best voices in all of KPOP.

KRY deserves 1st place. It looks like Cloud, Sparkyu, and Ryeosomnia haven't found this list! I should share this!

This duet is unique. It represents both the sexy and cute sides very well. Hyuna is the rapper, and Hyunseung is more comfortable singing. Their voices were made to go together.

Trouble Maker is one of the first sub-groups I ever liked, with the sexy Hyuna as the rapper and the weird but cute Hyunseung as the singer. They blend together very well!

Trouble Maker is the best of them all.

I can't get over that INCREDIBLE gift for my ears! Help! I can't stop listening to their collab!

When it comes to singing, the way their voices blend is no joke. Watch any K.R.Y concert, and you'll see they are the epitome of live singing. Talent, looks, personality - it's hard to beat Super Junior, and all of their sub-groups are definitely deserving of being the best.

Of course, Super Junior M! Their songs and dances are so good! Zhou Mi, who is a member of this subunit, wrote most of their songs. The members are all very talented and well-rounded artists. So SUPER JUNIOR-M ALL THE WAY! They are the most legendary subunit. They paved the way for KPOP in China.

True kings! I still listen to their songs. They don't get old!

The whole package! The multitalented kings!

Vocal kings. Their albums are gold!

Never knew that the combination of Leo and Ravi, out of all the VIXX members, would work so well! Their voices fit so well together that when they released Beautiful Liar, I was beyond pleasantly surprised! Can't wait to see what else they will release in the future!

Their voices go so well together, with Leo's high vocal range and Ravi's deep voice. It's a perfect combo, and their chemistry is amazing. We need another comeback from VIXX LR.

They have amazing chemistry. I nearly cried during Beautiful Liar.

Best sub-unit ever! Dongwoo and Hoya are amazing at producing together (it's like they're made for each other). Their rapping, dancing, and singing are awesome and perfectly suit their whole subunit!

They are amazing rappers, dancing machines, and good at singing too! They are super talented! When you stan talent, you stan Infinite H.

They are awesome, and their dance is unique and special, as expected from the main dancers of Infinite. The tune and melody of their songs are catchy and addictive. I think they are an awesome subunit. Their concept is different from Infinite.

These boys are talented no matter what, but it sucks that the Chinese members got mistreated.

I adore your style - unique and exciting.

The mom and dad of GOT7. I wish they'd do another sub-unit album! Even if they're in GOT7, it's not like they're leaving, but seeing the GOT7 team with sub-units would be great!

JB and Jinyoung? Oh, I miss the days of JJ Project, but I love them as GOT7 too.

I'm only just starting to get to know them well because I love GOT7 as well.

I was surprised at how young these boys are and that they debuted at such a young age.

They're the best - best dance, best rap, best voice, and they stay the best!

CL and Minzy are the best - better than Bom and Dara.

B.A.P is one of the fastest-growing K-pop idol groups nowadays. Before the group's debut, TS Entertainment wisely promoted prominent members Bang and Zelo to raise awareness of their original group.
