EXO-CBX

EXO-CBX (엑소-첸백시), also known as CBX, is the first official sub-unit of South Korean boy group EXO. Formed under SM Entertainment, the trio consists of Xiumin (Kim Min-seok), Baekhyun (Byun Baekhyun), and Chen (Kim Jong-dae), with the name drawn from the initials of each member's stage name. The group debuted on October 31, 2016, with the EP Hey Mama!, which topped both the Billboard World Albums chart and South Korea's Gaon Album Chart on release. Before their official debut, the three first appeared together on the Moon Lovers: Scarlet Heart Ryeo soundtrack with 'For You' in August 2016. Hey Mama! spanned electronic dance, R&B ballad, and retro pop across five tracks, establishing CBX as the vocal-focused side of EXO's catalog. Their first stage came at the Busan One Asia Festival in October 2016. CBX expanded into Japan in 2017 with the mini album Girls, followed by their first Japanese studio album Magic in 2018 and a sold-out Magical Circus arena tour across Yokohama, Fukuoka, Nagoya, and Osaka. Their second Korean EP, Blooming Days, arrived in April 2018 and produced their most-streamed track, 'Blooming Day'. In June 2023, all three members filed a joint lawsuit against SM Entertainment over earnings transparency. The dispute resolved within weeks, with the trio remaining under the label. In January 2024, CBX's solo and unit activities moved to INB100, the independent label founded by Baekhyun, while group activities under EXO remain with SM Entertainment. All three appeared at Billboard's K Power 100 event in August 2024.
