Kim Jae-han

Kim Jae-han, formerly known as J.Han, is a South Korean singer, dancer, actor, producer, lyricist, former member of ONEVOICES and SPECTRUM and current member of OMEGA X. He graduated from Seongdo High School. He made his debut in May 2015 (under the stage name J.Han) as part of the duo ONEVOICES with their first mini-album, "Flush". They were not successful and the agency, HAK Entertainment, decided to disband the duo right after promotions for their debut album ended. He switched agencies and re-debuted in May 2018 (using his real name) as SPECTRUM's main vocalist with their first EP, "Be Born". Unfortunately, after some initial success, the group could not continue to promote due to the COVID-19 pandemic and their agency, Wynn Entertainment had to cut expenses and decided to disband the group in July 2020.
