BLUEBEATZ Members Profile 2026: Seeon, Roa, Greeny, Haeun & Ain
BLUEBEATZ (블루비츠) is a Korean project girl band built around live instruments and vocal performance, emerging from KBSN’s K-pop audition program Voice on the Street. The group’s publicly documented profile currently names Seeon, Roa, Greeny, Haeun and Ain, while recent live-promotion material shows that the project’s performing lineup is still being defined, with Haeun and guitarist Hyevvi described as guest members for one August 2026 performance.
That distinction matters for anyone searching for a BLUEBEATZ members profile. The group is not yet presented through a conventional finalized idol-agency system with a permanent, formally published member sheet. Instead, its identity has been taking shape through the KBSN audition program, live performances and project-band promotions. KBSN itself describes Voice on the Street as a nationwide K-pop busking audition designed to discover performers outside a conventional studio setting.
As of this review, BLUEBEATZ does not have a publicly verified official debut date, fandom name or official group color. KProfiles currently categorizes the act as pre-debut and lists the debut date as unknown.
Quick Overview
| Fact | Information |
|---|---|
| Group | BLUEBEATZ |
| Korean Name | 블루비츠 |
| Group Type | Project girl band |
| Country | South Korea |
| Origin | KBSN’s Voice on the Street |
| Current public profile lineup | Seeon, Roa, Greeny, Haeun, Ain |
| Publicly documented live configuration | Roa, Seeon, Green; Ain/Ian on drums; Haeun and Hyevvi appeared as guest members in one August 28 performance |
| Debut Date | Not officially confirmed |

The current public evidence therefore supports five names on the group’s profile page, but not a simplistic “five permanent members” claim without qualification. The producer’s recent promotional post specifically labels Haeun and Hyevvi as guest members for the August 28 Hongdae performance, while the KProfiles page includes Haeun and Ain in its five-member profile.

Who Is BLUEBEATZ?
BLUEBEATZ is a new South Korean project girl band associated with KBSN’s Voice on the Street. Rather than being introduced first through a major entertainment company’s conventional trainee system, the project grew out of a performance-focused audition environment centered on live busking. KBSN’s official program description says the show was designed to find hidden talent on the streets, with minimal stage equipment and an emphasis on direct interaction between performers and audiences.
That origin helps explain the band’s structure. BLUEBEATZ is being presented around vocals plus live instrumentation, rather than as a dance-centered idol team. A recent producer post explicitly assigns vocals, keyboard, bass, drums and electric guitar within the project’s performance lineup, giving the act a stronger band identity than a typical pre-debut dance group.
The group’s public launch is still in an early stage. KProfiles lists BLUEBEATZ under pre-debut groups with no confirmed debut date, while recent promotional activity shows that the project is already performing publicly and building an audience through live stages.
How BLUEBEATZ Was Formed
The starting point for BLUEBEATZ is KBSN’s Voice on the Street, a K-pop audition program that uses busking as its core format. KBSN describes the show as an audition open to aspiring singers, hip-hop performers, buskers and members of the general public, with the goal of providing a real performance stage without the elaborate staging associated with many television music programs.
The official KBSN page confirms that Voice on the Street was a K-pop-focused busking audition. Later project promotion identifies BLUEBEATZ as a group born from that program.
This gives BLUEBEATZ a somewhat different formation story from a typical agency-launched girl group. The project grew around performers with existing musical backgrounds, and the band’s lineup has so far emphasized actual instrumental roles.
The BLUEBEATZ Lineup Question
This is the most important fact-checking issue surrounding the group.
KProfiles currently presents BLUEBEATZ as a five-member group consisting of Seeon, Roa, Greeny, Haeun and Ain. It assigns positions including lead vocalist, main vocalist, vocalist/bassist, vocalist/keyboardist and drummer.
However, a recent public post by producer TED KIM, whose LinkedIn profile identifies him with TED Entertainment, describes the August 28 Hongdae performance differently. The post lists:
- Roa – Main Vocal
- Seeon – Sub Vocal
- Green – Bass
- Ian – Drums
- Haeun – Keyboard, guest
- Hyevvi – Electric Guitar, guest
The same producer also separately published a post naming the drummer Ain and linking to Ain’s profile, while another post refers to the drummer as Ian. This creates a genuine public naming inconsistency that should not be silently “resolved” by assumption.
For this profile, KpopBio uses Ain as the member-profile name because that is the name used by the current KProfiles page and because the producer’s other post explicitly uses Ain. The article nevertheless records the Ain/Ian discrepancy so readers are not misled.
The same evidence suggests that Haeun’s participation may be performance-specific rather than proof of a permanently fixed five-person lineup, because the producer explicitly called her a guest member for the August 28 stage. Hyevvi was also described as a guest member rather than a permanent member.
Until a formal agency or project announcement establishes a definitive fixed lineup, that distinction should remain visible.
BLUEBEATZ Members
| Member | Publicly listed name | Reported role | Birth information currently available | Status |
|---|---|---|---|---|
| Seeon | Jeon Seeon | Lead vocalist | February 1994 | Listed member |
| Roa | Kwak Jieun | Main vocalist | October 6, 1994 | Listed member |
| Greeny | Kwon Haeun / Kwon Green | Vocalist, bassist | 1998 | Listed member |
| Haeun | Kim Haeun | Vocalist, keyboardist | October 9, 1999 | Listed by KProfiles; described as guest in one recent live lineup |
| Ain | An Ilyeop | Drummer | 2004 | Listed member; also called “Ian” in one producer post |
| Hyevvi | Hyevvi | Electric guitarist | Not publicly established in reliable sources checked | Guest performer in the cited August 28 lineup |
The detailed biographical information in the table is largely drawn from KProfiles because there is no currently indexed official BLUEBEATZ member database providing a comparable full biography. Accordingly, readers should distinguish between project-level facts supported by KBSN or producer material and individual biography fields reported by a secondary profile source.
Seeon Profile
Seeon (시온) is publicly listed as one of BLUEBEATZ’s vocalists, with KProfiles identifying her as a lead vocalist. The same profile gives her birth name as Jeon Seeon (전시온) and her birth month and year as February 1994.
Because a full day of birth is not publicly established in the stronger sources checked, it would be inaccurate to invent an exact birthday. KProfiles identifies her zodiac sign as Pisces, but for KpopBio the more important fact is her musical background.
Seeon already had an identity as an independent singer before BLUEBEATZ. KProfiles records her solo debut on April 30, 2021, with “연월가 (戀月歌)”. It also says she studied music at university and won the Sangmyung Award at the 39th SMBS Jaha Song Festival in 2018 and a gold prize at the Ggilook-Ggilook Youth Artist Online Contest in 2021.
That background matters because BLUEBEATZ is not being assembled entirely from unknown trainees. Seeon’s prior solo activity gives the project one member with an existing singer-songwriter profile.
KProfiles also identifies piano among her instruments. That detail fits the wider musical philosophy of BLUEBEATZ, which relies on musicians who can contribute directly to live arrangements rather than relying exclusively on backing tracks.
Her current official BLUEBEATZ position should still be described conservatively. KProfiles calls her a lead vocalist, while the more recent producer post calls her Sub Vocal for the August 28 performance. That difference is another example of why temporary performance credits should not automatically be treated as permanent group positions.
Roa Profile
Roa (로아) is the member with the most extensive documented idol-industry history among the names currently associated with BLUEBEATZ.
KProfiles identifies her birth name as Kwak Jieun (곽지은) and gives her birthday as October 6, 1994. It lists her as main vocalist and describes previous activities with X and the band Someilsang, alongside several pre-debut projects.
Her résumé also includes solo music. KProfiles says Roa debuted as a soloist on April 24, 2017, with the single “Red Lips.” The same profile records participation in the survival show Stellar Sugar and membership in the project I-CODE.
Roa’s earlier experience makes her particularly significant to BLUEBEATZ’s current setup. She has already worked through several forms of Korean pop performance, including group activity and solo releases, which gives the new project an experienced vocal center.
The most recent producer material reinforces that role. In the August 28 performance promotion, TED KIM identifies Roa as Main Vocal, matching KProfiles’ main-vocal designation and making this one of the more consistently documented current roles in the group.
Roa’s public profile also includes songwriting and a cappella skills, as well as experience connected to musical theatre and performance. These are secondary-source claims, but they point toward a performer whose work extends beyond standard idol choreography.
Greeny Profile
Greeny (그리니), also referred to as Kwon Green, is the bassist and one of BLUEBEATZ’s vocalists. KProfiles gives her birth name as Kwon Haeun (권하은) and birth year as 1998.
Unlike some project members who are primarily associated with singing, Greeny’s main differentiator is her instrumental role. KProfiles says she began studying contrabass around her final year of high school and later studied bass in the applied music department at Dongduk Women’s University. It also lists piano among her instruments.
Greeny has previous group experience as well. KProfiles identifies her as a member of 12BH and says she previously participated in the three-member co-ed band E.V.C. The profile also records her solo release “0nCloud9”, issued on February 26, 2020 under her birth name.
That history is especially relevant to BLUEBEATZ because the group is explicitly being marketed as a band. A recent producer post names Green as the project’s bass player, placing the bass line directly inside the core stage setup rather than treating the group as a conventional vocalist-only act.
Greeny’s position may therefore be one of the clearest indicators of what separates BLUEBEATZ from many pre-debut idol groups: the instrumentalist is not hidden behind a concept. The musician is part of the concept.
Haeun Profile
Haeun (하은) is listed by KProfiles as Kim Haeun, born October 9, 1999, with the role of vocalist and keyboardist.
Her background is unusually long for a newly introduced project. KProfiles says she previously belonged to GOOD DAY, LATENCY and cignature, while also having been part of the pre-debut group Littles. The profile additionally records several years of trainee experience and work as a K-pop dance instructor.
She therefore brings two useful dimensions to BLUEBEATZ: prior idol-group experience and the ability to contribute through keyboard performance.
There is, however, an important current-status caveat. The producer’s August 28 promotional post identifies Haeun as Keyboard – Guest Member for that performance. That means KpopBio should not automatically describe her as a permanently fixed core member solely because a secondary profile page currently includes her in the lineup.
That does not mean Haeun is unrelated to BLUEBEATZ. It means the project’s public performance structure was flexible enough to use guest musicians. As the group moves closer to a formal debut, an official member announcement would be the appropriate source for resolving her status.
Ain Profile
Ain (아인) is listed by KProfiles as An Ilyeop (안일엽) and as BLUEBEATZ’s drummer and youngest member. Her birth year is given as 2004, although a full date is not provided.
Her profile emphasizes formal music education. KProfiles says she attends Dongduk Women’s University, where she majors in drums, and previously studied at Kyungnam Arts High School and Gwangryeo Middle School. It also says she has taught drums at music academies.
Ain is important to the lineup question because the producer evidence contains an apparent naming variation. One recent promotional post explicitly links to an Ain profile and uses Ain in the lineup, while another calls the drummer Ian.
KpopBio should not silently replace one with the other. The safest current approach is to use Ain because that is the name in the detailed member profile and one of the producer’s posts, while noting the alternative “Ian” spelling/name in the editorial record.
What About Hyevvi?
Hyevvi appears in the producer’s August 28 project-band promotion as the electric guitarist and a guest member. The source establishes her performance role for that event, but I could not find a reliable public source during this review establishing a full biography, birth date, permanent-member status or formal agency relationship for her.
For that reason, Hyevvi should not be folded into the main five-member biography table as though her permanent membership were already established.
Her appearance does, however, tell readers something useful about BLUEBEATZ: the project is capable of expanding or modifying its live instrumentation depending on the performance.
BLUEBEATZ’s First Public Performance
TED KIM’s public promotion identifies August 28, 2026 as BLUEBEATZ’s first Hongdae performance at SPACE HONG, scheduled for 7 p.m. KST as part of a Voice on the Street joint performance. The post describes the band as a newly established project girl band and invites audiences to follow its first steps.
This is an important milestone, but it should not be confused with an official music debut. A live debut or first public performance is not automatically the same thing as an officially released debut single.
KProfiles still lists BLUEBEATZ’s debut date as unknown. The current evidence therefore supports the following distinction:
First documented live performance: August 28, 2026
Official music debut: Not yet independently confirmed.
BLUEBEATZ’s Musical Identity
The group’s defining feature is its live-band structure.
In the August 28 promotional lineup, the project used a main vocalist, supporting vocalist, bass, drums, keyboard and electric guitar. That arrangement is much closer to an idol band or performance band than to a standard idol group relying primarily on dance choreography and backing instrumentation.
The choice of “Fly Me to the Moon” for a documented BLUEBEATZ live performance also suggests that the group is comfortable working with classic pop standards rather than presenting an identity based only on original idol singles. A producer post promoting the group specifically linked to a BLUEBEATZ performance of the song.
At the same time, the word “K-pop” is central to the project’s marketing because BLUEBEATZ was created through a KBSN K-pop audition program. The group’s more interesting characteristic is therefore the meeting point between K-pop presentation and live-band musicianship.
Career Timeline
| Date | Development | Verification |
|---|---|---|
| 2025–2026 | KBSN airs Voice on the Street, a K-pop busking audition | KBSN official program page |
| 2026 | BLUEBEATZ emerges from the Voice on the Street ecosystem | Producer / project promotion |
| August 28, 2026 | First documented Hongdae performance at SPACE HONG | Producer TED KIM |
| August 28, 2026 | Live lineup includes Roa, Seeon, Green, Ain/Ian, with Haeun and Hyevvi described as guests | Producer TED KIM |
| September 2026 | BLUEBEATZ remains listed as a pre-debut group with no confirmed debut date | KProfiles |
| September 2026 | Public reports indicate future touring and a Christmas project are being discussed/teased | Secondary social-media reporting; not treated as an official schedule |
The final item should not yet be treated as a confirmed tour announcement. A recent Nugu Archive post says BLUEBEATZ has shared plans for a Christmas Carol album and Japanese/West Coast U.S. touring, but that information comes through a social-media aggregation account rather than a primary announcement. It is therefore developing information, not an established itinerary.
Music and Major Releases
BLUEBEATZ has not yet been documented with a formally released original debut single or EP in the strongest sources checked.
The group’s documented music activity so far is performance-oriented. Its public promotion includes a live rendition of “Fly Me to the Moon”, while the project continues to be listed as pre-debut.
| Release / Performance | Type | Date | Status |
|---|---|---|---|
| “Fly Me to the Moon” | Live performance | 2026 | Publicly documented performance |
| Official debut single | Original release | Unknown | Not yet verified |
| Debut EP / album | Original release | Unknown | Not yet verified |
This is an area where many pre-debut profile pages become unreliable by listing planned material as though it has already been released. KpopBio should keep BLUEBEATZ’s discography intentionally short until a verified music-release announcement exists.
Major Achievements
BLUEBEATZ is too new to support claims about major chart records, music-show wins or established awards.
The most meaningful verified achievement to date is the launch of the project into live public performance, including its August 28 Hongdae show. That stage established the group as a real performing project rather than simply a name appearing on a pre-debut list.
No independently verified:
- Korean music-show win
- major Circle Chart ranking
- Billboard chart result
- Hanteo sales milestone
- major award
- certified streaming milestone
was found during this review.
That is exactly the kind of information a responsible profile should leave blank rather than manufacture.
Latest Verified Updates
Last Updated: September 9, 2026
BLUEBEATZ is still best described as a pre-debut project girl band. KProfiles lists the group as pre-debut with its official debut date unknown.
The most concrete recent activity is the group’s August 28 Hongdae performance. Public promotional material described it as BLUEBEATZ’s first step and provided a live member/instrument configuration that included guest performers.
The group also has an official Instagram handle listed as @bluebeatz_official, which is currently the clearest social destination for readers following the project.
What We Verified
The evidence currently supports these points:
- BLUEBEATZ is a South Korean project girl band.
- The project is connected to KBSN’s Voice on the Street.
- KProfiles currently lists Seeon, Roa, Greeny, Haeun and Ain.
- The project is being built around vocals and live instruments.
- A documented first Hongdae performance took place on August 28, 2026.
- Roa, Seeon and Green are identified in producer material as core vocal/bass performers for that stage.
- Haeun and Hyevvi were explicitly described as guest members for the August 28 event.
- The drummer appears as Ain in one producer post and Ian in another.
- BLUEBEATZ’s formal debut date remains unconfirmed.
What Is Not Officially Confirmed
The following should not be published as settled facts without a stronger primary source:
- Exact official permanent lineup.
- Whether Haeun is a permanent member or a recurring guest musician.
- Whether Hyevvi will become a permanent member.
- Whether “Ain” and “Ian” are simply alternate forms for the same drummer.
- Formal agency or label arrangement for the group.
- Official debut date.
- Official debut song or EP.
- Official fandom name.
- Official fandom color.
- Confirmed Japanese or U.S. tour dates.
- A Christmas album release date.
- Major awards, charts or streaming milestones.
The uncertainty is not unusual for a project at this stage. BLUEBEATZ is already performing, but its formal idol-group infrastructure is still being established publicly.

Why BLUEBEATZ Is Worth Watching
The most interesting thing about BLUEBEATZ is that the project is being built around actual musicianship.
K-pop has produced successful idol bands before, but BLUEBEATZ’s launch material places live instrumentation directly in the foreground. The band’s public performance roster identifies dedicated parts for bass, drums, keyboard and guitar rather than treating instruments as decorative props.
The members also arrive with histories that predate the group. Roa and Seeon have solo or previous-group credits, Greeny already has experience as a bassist and independent artist, Haeun has extensive previous idol experience, and Ain has formal drum training.
That makes BLUEBEATZ less interesting as a simple “new K-pop group” and more interesting as an experiment in how a K-pop-style audition system can produce a project with an explicitly live-band identity.
For KpopBio readers, that is the part worth following as the project moves toward a formal debut.
Conclusion
BLUEBEATZ is still at the beginning of its public career, but the project already has a clearer musical identity than many pre-debut acts. Its connection to KBSN’s Voice on the Street, its emphasis on live instruments and the previous experience of several performers give the group a foundation that extends beyond a conventional trainee profile.
For now, the safest description is a Korean pre-debut project girl band with a publicly listed five-member profile but an evolving live lineup. Roa, Seeon, Greeny, Haeun and Ain are the names currently documented in the principal profile source, while the August performance material adds important context about guest musicians and the Ain/Ian naming issue.
