4Men
4Men (Korean: 포맨), stylized as 4MEN, is a South Korean vocal group specializing in rhythm and blues (R&B) and ballad music, renowned for its harmonious and emotionally resonant performances.[1] Formed in 1998 as a quartet, the group debuted on February 1, 1998, with their first studio album, Four Men First Album, marking the start of a career defined by soulful vocals and heartfelt songwriting.[2] Over the decades, 4Men has evolved through multiple lineup changes, spanning four generations of members while maintaining its core focus on delivering sincere, moving music that transcends visual appeal or age demographics.[1] The current fourth-generation lineup as of November 2025, active since 2021, consists of Ha-eun (born March 3, 1994), Yosep (born December 4, 1995; also known as Joseph), and Han-bin (born June 24, 1997), who emphasize creating songs that evoke deep emotion and connect with listeners through pure vocal expression.[1] The group was on hiatus from 2024 to 2025 due to Han-bin's mandatory military service, which he completed on November 12, 2025.[3] Under the management of MAJOR9 since 2017, the group has released numerous albums, singles, and original soundtrack contributions, solidifying its status as a staple in the Korean ballad genre with a legacy of over 25 years of live performances and fan engagement.[4]History
Formation and debut (1998–1999)
4Men was formed in 1998 as a four-member R&B vocal ensemble consisting of Yoon Min-soo, Jeong Se-young, Han Hyeon-hee, and Lee Jeong-ho. The group emerged during the late-1990s South Korean music scene, a period marked by the shift from traditional ballads and trot to more diverse genres including R&B and vocal harmony groups, with ensembles like them selected to emphasize emotional, ballad-focused performances.[5][2] On February 1, 1998, 4Men debuted under Kingpin Entertainment with their first studio album, Four Men First Album, a collection of nine tracks highlighting their harmonious vocals and R&B style. Key highlights included the opening track "Good-Bye," the introspective ballad "The One Who Loved Me More Than I Loved Myself" (나보다 더 나를 사랑한), and the romantic "First Love" (첫사랑), which exemplified their focus on heartfelt lyrics and smooth melodies.[6][7] The album's release was supported by early promotional efforts, including live performances and appearances on major music television programs, which helped introduce the group's sound to audiences amid a competitive landscape dominated by emerging pop acts. These initial activities laid the foundation for their career, leading to lineup adjustments in the early 2000s.[2]Early career and lineup changes (2000–2009)
Following the release of their debut album in 1998, 4Men issued their second studio album, Poem (titled 이렇게 천일동안 모으면 이별이 사라진다고 했다 in Korean), in 2000, featuring heartfelt ballads like "Sad Song" and "Orange Girl" that appealed to fans of emotional R&B and helped solidify their niche in the ballad genre.[8] In 2001, shortly after the album's release, founding member Yoon Min-soo left the group to form the R&B duo Vibe with Ryu Jae-hyun, initiating the first significant lineup change and shifting 4Men to a three-member configuration.[9] The remaining original members—Jeong Se-young, Han Hyun-hee, and Lee Jeong-ho—then faced mandatory military enlistment, resulting in a multi-year hiatus that stalled the group's momentum and activities.[10] The group reemerged in 2006 with newcomer J1 (real name Song Jae-won) joining as the fourth member, releasing their third studio album Andante to mark their return and emphasize layered vocal harmonies amid the evolving K-pop landscape.[11] This reformation came after the original lineup's service obligations, highlighting the challenges of maintaining continuity in South Korea's male idol groups during the 2000s. Further instability followed in 2008, when the existing members departed, leading to a complete revamp with the addition of Shin Yong-jae, Kim Young-jae, and Kim Won-joo as the third-generation lineup; they debuted this era with the mini-album First Kiss, which included tracks like "Baby Baby" and focused on poignant, harmony-driven lyrics about love and loss.[12] These transitions, coupled with military duties, underscored the early instability that shaped 4Men's identity before their commercial breakthrough in the following decade.Peak popularity and expansions (2010–2019)
In 2010, 4Men achieved a significant breakthrough with the single "I Can't" (featuring Mii), released as part of their special album The 3rd Generation. The track became one of their most successful releases, earning a nomination for Best Vocal Performance (Group) at the 2010 Mnet Asian Music Awards and contributing to the group's win for Top 10 Artist at the Melon Music Awards that year. This ballad, known for its emotional depth and harmonious vocals, marked a turning point, propelling 4Men into greater mainstream recognition amid their trio lineup of Shin Yong-jae, Kim Young-jae, and Kim Won-joo at the time. The following year, 4Men solidified their position in the ballad genre with the release of their full-length album The Artist in June 2011. The lead single "Once While Living" (also known as "Salda-ga Hanbeonjjeum") garnered widespread acclaim, earning a nomination for Best Vocal Performance (Group) at the 2011 Mnet Asian Music Awards and peaking prominently on digital charts, further establishing the group's dominance in emotional R&B ballads.[13] This era highlighted their consistent chart success and vocal synergy, with the album showcasing a blend of introspective lyrics and layered harmonies that resonated with audiences. During the mid-2010s, 4Men expanded their influence beyond original releases into drama soundtracks, notably contributing "Only You" to the OST for the popular MBC series Gu Family Book (also known as Kangchi, the Beginning) in 2013. The poignant ballad earned them the OST Award at the 6th Korea Drama Awards, underscoring their versatility in enhancing dramatic narratives with heartfelt performances.[14][15] This venture into OSTs broadened their reach, aligning their music with high-profile television productions and attracting new fans. The group continued their momentum with key releases such as the 2014 re-recorded album 4Men the 5th Album , which revisited their debut material with matured vocals, and the 2015 mini-album Study Abroad. These projects were complemented by collaborations, including features with artists like Huh Gak, and live tours across Asia, including performances in Japan and Southeast Asia that showcased their live vocal prowess to international audiences. After Kim Young-jae's departure in 2014, 4Men continued as a duo of Shin Yong-jae and Kim Won-joo, maintaining stability amid growing solo pursuits, setting the stage for a temporary hiatus in 2019.Hiatus, reformation, and recent years (2020–present)
Following the release of their album Remember Me in 2017, 4Men entered a hiatus in 2019 when members Shin Yong-jae and Kim Won-joo departed the group after their exclusive contracts with MAJOR9 expired, allowing them to pursue solo endeavors.[2] This marked the end of the third-generation lineup after over a decade together, leaving the group's future uncertain amid shifting priorities in the R&B vocal scene.[15] The group reformed in April 2021 under the MAJOR9 label with a fourth-generation trio comprising Haeun, Joseph, and Hanbin, signaling a fresh start for the veteran act.[2] On April 14, 2021, they staged their comeback with the single "Still" (Korean: "urin ajik heeojigi jeon," meaning "Before We Break Up"), accompanied by the EP The Eternal, which featured tracks like "Eternal" and "Truly" and reaffirmed their roots in emotive R&B ballads with layered harmonies and introspective lyrics.[16][17] In the years since, 4Men's activities have been more restrained, focusing on sporadic digital releases and fan engagements rather than large-scale promotions. Haeun enlisted for mandatory military service on June 13, 2022, and was discharged on December 12, 2023. Notable among these was the single "Lost Mind" (Korean: "michingeoni") released on March 27, 2023, a poignant ballad produced during Haeun's military service, highlighting themes of lingering regret in relationships.[18] Additional singles like "Butterfly Grave" in 2023 and "Even If I'm Crazy" in June 2024 continued this pattern of intimate, vocal-driven tracks, often shared through online platforms and modest events to maintain connection with longtime supporters. Hanbin enlisted for military service on May 13, 2024, and was discharged on November 12, 2025, during which the group operated as a duo. As of November 2025, 4Men operates as an active trio under MAJOR9, though their profile remains lower than the expansive popularity of the 2010s, with no major tours or album announcements reported; the label continues to support their output through digital channels, emphasizing sustained vocal artistry over commercial peaks.[19]Members
Current members
The current lineup of 4Men consists of three vocalists: Haeun, Joseph, and Hanbin, who formed the group's fourth-generation iteration following its 2021 reformation under MAJOR9 Entertainment.[20] This trio debuted with the single "Still" on April 14, 2021, and released their first mini-album as a unit, The Eternal, in June 2021, marking a revival of the group's R&B ballad style.[21] Haeun, born Kim Ha-eun on March 3, 1994, in Seoul, South Korea, serves as a lead vocalist in the group.[22] Prior to joining 4Men, he pursued a solo career, debuting with the single "Love…ing (Reply)" in September 2018, and has been recognized for his emotive delivery in ballad performances.[22] Since the 2021 reformation, Haeun has been instrumental in the group's layered vocal arrangements, contributing to the harmonized leads that define their comeback tracks.[20] Joseph, born Yoon Yosep on December 4, 1995, in Seoul, South Korea, is a vocalist known for his rich tone suited to R&B genres.[23] He debuted as a solo artist under the name Yunyo with the single album B&W in April 2016 and studied at the Seoul Institute of the Arts, honing his musical foundation.[24] In the reformed 4Men, Joseph has focused on delivering stable mid-range support in their ensemble singing, helping to sustain the group's signature emotional depth in releases like The Eternal.[20] Hanbin, born Lee Han-bin on June 24, 1997, is the youngest member and a vocalist with prior experience in independent music circles, including releasing the OST "Over the Moon" for the 2019 JTBC drama Beautiful World.[3] He graduated from Dong-Ah University of Media and Arts and has showcased his live performance skills on programs such as King of Mask Singer (episodes 412–413) and Immortal Songs (episodes 510–511, 518).[3] He completed his mandatory military service from May 13, 2024, to November 12, 2025; during this period, he remained an active member of the group.[25][3] In 4Men, he often handles dynamic ad-libs and lower vocal lines, enhancing the trio's live energy prior to his enlistment.[3] Post-2021, the trio's vocal blend has preserved 4Men's hallmark harmony through tight-knit arrangements that emphasize emotional resonance and seamless transitions between leads, adapting the original quartet's style to a more intimate three-part structure.[20] This shift from the four-member original era allows for greater focus on individual strengths while maintaining the group's cohesive ballad sound.[20]Former members
The original lineup of 4Men, formed in 1998, consisted of Yoon Min-soo as tenor, Jeong Se-young as vocalist, Han Hyeon-hee as vocalist, and Lee Jeong-ho as baritone.[5][26] Yoon Min-soo departed in 2001 to form the R&B duo Vibe, reducing the group to a trio and shifting their sound toward a more mature ballad style during their early promotions.[5][27] The remaining original members—Jeong Se-young, Han Hyeon-hee, and Lee Jeong-ho—continued until 2008, when all withdrew amid a group hiatus, leading to the formation of the short-lived R&B project Someday by Jeong and Han in 2009.[28] In the mid-2000s, during the second generation, J1 (real name Song Jae-won) joined as main vocalist from 2006 to 2008, contributing to their third studio album Andante and helping maintain the group's harmonic R&B focus before the lineup's dissolution.[28][2] The third generation began in 2008 with the addition of Kim Young-jae as alto (2008–2014), Shin Yong-jae as lead vocalist (2008–2019), and Kim Won-joo as vocalist (2008–2019), revitalizing the group with a fresh, emotive vocal dynamic that defined their peak era albums like First Kiss.[28][29] Kim Young-jae's exit in 2014 transitioned the group to a duo format, emphasizing Shin and Won-joo's interplay, though Won-joo's military enlistment in 2015 created a temporary gap in activities.[2][30] The third generation concluded in 2019 when Shin Yong-jae and Kim Won-joo departed after their contracts with MAJOR9 expired, forming the vocal duo 2F and marking the end of that era's signature soulful harmonies.[31] Shin Yong-jae pursued solo ventures, releasing his first full-length album Dear in 2022 after earlier mini-albums, while enlistments and individual pursuits like Won-joo's OST work influenced several transitions.[32] These lineup shifts often altered 4Men's vocal texture, from the original quartet's robust layering to the duo's intimate delivery, before the current members adapted to preserve the group's ballad legacy.[33]Artistry
Musical style
4Men's music primarily encompasses R&B-infused ballads incorporating soul elements, delivered through layered vocal harmonies that evoke deep emotional resonance.[33][34] Their sound blends K-soul with traditional Korean ballad structures, prioritizing heartfelt expression over rhythmic drive.[33] The group's vocal approach relies on multi-part harmonies, originally structured around four voices to create acapella-like blends with rich tonal depth, though adapted to three parts with the current lineup.[20][2] In live performances, they incorporate ad-libs to enhance emotional peaks, featuring falsetto leads supported by resonant bass undertones for dynamic contrast.[35] Over time, their production has shifted from piano-centric acoustic arrangements in early works to more contemporary setups with subtle electronic elements in 2010s releases, particularly OST contributions.[36] This evolution maintains lush, polished soundscapes suited to slow-tempo tracks typically ranging 60–80 BPM, centered on themes of heartbreak and longing that set them apart from faster-paced K-pop peers.[35] Their style draws brief nods to Western R&B influences in harmonic phrasing and soulful phrasing.[33]Influences and songwriting
4Men's musical influences draw heavily from the R&B genre, which they helped pioneer in South Korea following their debut in 1998. As one of the early vocal harmony groups in the Korean music scene, the quartet emulated the smooth, emotive styles prevalent in international R&B, emphasizing layered vocals and heartfelt ballads. A key figure in their development was Yoon Min-soo, the group's original lead vocalist, who produced their third lineup—including members Shin Yong-jae and Kim Won-joo—infusing their sound with soulful elements drawn from his subsequent work with the R&B duo Vibe.[27][12] In terms of songwriting, 4Men's members have played active roles, particularly Shin Yong-jae, who contributed lyrics and arrangements to several of the group's signature tracks during the 2010s. Notable examples include "Say I Love You," "I Love You," "I Can't Love You Anymore," and "I'm Sorry," where his involvement helped shape the introspective emotional depth of their releases. The group also collaborated closely with external producers, such as Yoon Min-soo, who penned the hit "Can't Do" in 2010 and oversaw compositions for their 2011 album The Artist, marking a shift toward greater member participation in lyric-writing and overall creative input.[37][12] Lyrically, 4Men's work consistently explores themes of love, loss, and introspection, often portraying the complexities of relationships through motifs of enduring emotions and personal reflection. Songs like "Can I Love Again" delve into second chances in romance, while tracks such as "Butterfly Grave" evoke sadness and longing, aligning with the group's ballad-centric style that resonates across their discography. This thematic consistency underscores their focus on "eternal" sentiments, from youthful heartbreak to mature emotional resilience.[34][12] Following the departure of the third-generation members in 2019 and the formation of the fourth-generation lineup in 2021, 4Men has adapted their songwriting process in the 2020s by incorporating more collaborative elements with contemporary producers to maintain relevance in the evolving K-pop landscape, as seen in OST contributions like "Love Me" from Reborn Rich in 2022.[20][38]Discography

Critics noted its refined balladry and commercial success through lead single promotions.[40]Extended plays
4Men's extended plays, often referred to as mini-albums in the K-pop industry, have played a key role in maintaining the group's visibility during periods between full-length releases, allowing for quicker comebacks with 4–6 tracks focused on their signature ballad style. These releases typically feature a mix of self-produced material and collaborations, emphasizing emotional vocals and romantic themes to bridge gaps in their studio album cycle.[2] The group's first mini album, First Kiss, was released on October 7, 2008, by The Vibe Entertainment, containing 4 tracks. It marked an early effort to revitalize their sound after initial studio albums.[41] In 2010, Sorry followed, peaking at #9 on the Gaon Album Chart and featuring 6 tracks that highlighted the quartet's harmonious arrangements.

In addition to their studio albums and extended plays, 4Men has released a special album and a live recording that highlight their vocal harmonies and career milestones. The special album The 3rd Generation, issued in 2010 under YWHO, features tracks from the group's third lineup, including "Knock Knock Knock" and "Everything," emphasizing their evolving sound during a period of member changes. The album served as a transitional release, showcasing fan-favorite ballads and new material to mark the group's adaptation to its updated membership. A collaboration compilation, Baby Baby + 4MEN, was released on March 4, 2010, blending 4Men's vocals with tracks from singer Baby Bay for a joint project that combined R&B elements with ballad covers and originals.

The album also features a new original song, "Hug Me," adding fresh content to the retrospective set.[42]Singles
4Men's singles career reflects their enduring appeal in the South Korean ballad scene, evolving from modest physical releases in the late 1990s to major digital hits in the 2010s and beyond, often leveraging drama OST tie-ins and vocal harmonies for promotion. Early efforts like their 1998 debut track from the Four Men First Album garnered limited airplay amid a competitive market dominated by idol groups, setting a foundation for their R&B-style ballads. By the early 2000s, singles such as those from their second album achieved minor chart placements. The group's breakthrough came in the digital era with "I Can't" (feat. Miiii) in 2010, a poignant breakup ballad from their special album The 3rd Generation, which peaked at #3 on the Gaon Digital Chart and amassed over 3 million downloads, earning double million certification from Gaon for its commercial success. This track exemplified 4Men's shift to digital platforms, where emotional lyrics and layered vocals resonated with listeners, accumulating tens of millions of streams on services like Melon in subsequent years—exceeding 10 million for several 2010s releases—boosted by karaoke popularity and radio rotations. Promotional strategies emphasized music show appearances and collaborations, helping it rank among the year's top digital singles.[43] Following this momentum, "Once While Living" in 2011, tied to an OST project, peaked at #2 on the Gaon Digital Chart weekly ranking and placed #32 on the year-end chart, with over 2.5 million downloads reflecting its inspirational theme and tie-in exposure. The single's success highlighted 4Men's adeptness at OST promotions, where drama synopses amplified streaming via soundtrack playlists. Later releases continued this trend; "Only You" in 2013, featured in the popular drama Gu Family Book, debuted strongly and ranked in the top 100 year-end Gaon Digital Chart with high streaming points, its dramatic narrative driving cultural buzz and over 10 million cumulative streams.[44][14] In the streaming-dominated 2020s, 4Men adapted by releasing concise digital singles under series like "Made in 4MEN," focusing on nostalgic ballads for mature audiences. "Still" (2021) reached #15 on the Circle Digital Chart, benefiting from targeted social media teasers and live sessions that engaged long-time fans, while accumulating steady streams through playlist integrations. Similarly, "Lost Mind" (2023) charted at #20 on Circle, promoted via behind-the-scenes vocal breakdowns on YouTube, underscoring their strategy of authenticity over viral trends amid a landscape favoring younger idols. "Butterfly Grave" (2023) peaked at #15 on Circle Digital. "Even If I'm Crazy" (2024) also reached #15 as of mid-2024. These later singles, often surpassing 10 million streams for 2010s hits revisited in algorithms, illustrate 4Men's sustained relevance through quality vocal delivery rather than high-budget visuals.[2][45]| Single Title | Release Year | Peak Chart Position | Key Notes |
