Jeonghan

Yoon Jeonghan (윤정한) is a South Korean singer and vocalist in SEVENTEEN, the multi-unit group under Pledis Entertainment that redefined how K-pop acts structure their teams. As part of the Vocal Unit alongside Woozi, DK, Joshua, and Seungkwan, Jeonghan has been central to SEVENTEEN's signature harmony-driven sound since their 2015 debut with "Adore U." Born October 4, 1995 in Seoul, he trained for two years before debut. Known for his visuals and soft vocal tone, Jeonghan became the face of the group's visual identity early on, though his contributions extend far beyond aesthetics. In 2024, he and Wonwoo formed the subunit JxW, releasing "This Man" with the lead single "Last Night" which moved over 787,000 copies in its first week. The album marked a new direction showcasing his solo artistic capabilities. Jeonghan began his mandatory military service in September 2024, temporarily stepping back from group activities. Prior to enlistment, he hosted SBS's weekly radio show "Key of Future" from 2022 to 2023, demonstrating his range as an entertainer beyond music. His endorsement portfolio includes luxury brands and lifestyle campaigns across Asia, cementing his status as one of K-pop's most marketable talents.
