If you think K-pop is all about big groups with flashy choreography and catchy songs, think again! Some of the most interesting and unique music actually comes from subunits, smaller groups formed from members of a larger idol group. These subunits give idols a chance to try out different styles, experiment with concepts, and shine in ways the main group might not allow.
Whether you’re a die-hard fan or just starting your K-pop journey, exploring subunits is like finding hidden gems. From emotional ballads to funky pop and experimental tracks, subunits bring a fresh perspective to your favorite groups. So, without further ado, here are the top 10 K-pop subunits you absolutely need to know.
1. Super Junior-K.R.Y
When it comes to vocal powerhouses, Super Junior-K.R.Y takes the crown. This subunit features Kyuhyun, Ryeowook, and Yesung, the three main vocalists of Super Junior. While the main group often rocks upbeat dance tracks, K.R.Y focuses on emotional ballads that hit right in the feels.
If you love songs that make you pause and just listen, K.R.Y is your go-to. Their live performances are legendary, proving that great vocals can steal the spotlight even without intense choreography. Fans especially love their drama OSTs, which add a more intimate, soulful side to Super Junior’s music.
2. EXO-CBX
EXO-CBX was the first official subunit of EXO, made up of Chen, Baekhyun, and Xiumin. Unlike EXO’s larger, often more dramatic concepts, CBX goes for fun, playful, and experimental sounds. Hits like “Hey Mama!” and “Blooming Day” show off their smooth vocals and infectious energy.
Even with just three members, CBX manages to command the stage. Their music videos are colorful and vibrant, and they’re perfect for fans who enjoy catchy songs that still have depth. If you love EXO but want a lighter, more playful side of the group, CBX is a must-listen.
3. NCT U
