How to Sing Like Sunghoon (ENHYPEN): Vocal Range, Airy Tone & the Technique Behind It

Singing like Sunghoon of ENHYPEN is less about matching a specific vocal range — no reliable public figure exists for it — and more about training two connected skills: a light, airy tone built on precise breath control, and a smooth boundary between falsetto and full voice that lets his dynamics shift without an audible break. Once you study the mechanics behind those two skills through his most-referenced songs, most of the technical challenge becomes trainable, regardless of your own natural voice type.

Safety note: None of the techniques described here should cause throat soreness, a pressed feeling in the larynx, or hoarseness lasting beyond 24 hours. Sunghoon's airy tone and dynamic control come from breath support and light, controlled fold closure, not from forcing volume or squeezing the throat. If you feel strain, reduce volume and rest. Consult an ENT specialist for hoarseness lasting more than two weeks.

Sunghoon's Vocal Profile

A clear, sourced numeric vocal range for Sunghoon of ENHYPEN isn't available — the public data is too thin to state a figure with confidence, so this guide anchors on documented tone characteristics and song moments instead. Sources describe his role in the group's vocal lineup differently — some list him as a lead dancer and sub-vocalist rather than main vocalist — so this guide treats him as a member of ENHYPEN whose singing style is worth studying, without asserting a specific position title.

What is consistent across sources is a airy, silky vocal tone, with a light, near-head-voice quality that persists even on fuller lines, alongside a delicate touch for dynamic shading.

Two stylistic threads run through his catalog:

• A light, airy tone color — a controlled amount of air mixed through the production, closer to a head-voice quality than a fully closed chest tone, even in mid-volume passages.
• Careful dynamic shading — subtle volume and intensity changes within a single phrase, rather than staying at one dynamic level throughout.

Rather than anchoring practice to a disputed position label or range figure, it is more useful to study how he holds that airy color and dynamic nuance across different song sections — which is the focus of the rest of this guide.

Sunghoon's Signature Songs — by Vocal Challenge

Approaching his catalog by what each song demands rather than by popularity gives you a training order. Transpose any of these to a key that fits your own range.

Start at the top of the table and move down only as each technique becomes reliable. Holding the airy quality through the fuller "Drunk-Dazed" chorus is the destination, not the starting line.

The 3 Techniques Behind Sunghoon's Sound

Airy tone, near-head-voice production

This is the core of his sound: a light vocal fold closure that lets a controlled amount of air pass through, giving the tone a near-head-voice quality even when the line isn't technically in head register. Producing it stably — rather than as a breathy whisper — requires steady breath support to compensate for the extra air escaping per phrase. The most common mistake is reducing breath support along with volume, which collapses pitch instead of preserving the airy color. The mix voice practice guide covers the fold-closure coordination this builds on.

Falsetto-to-full-voice boundary control

Moving between falsetto and full voice without an audible break requires gradually adjusting fold closure across the passaggio rather than switching mechanisms abruptly. This is what lets a phrase shift in intensity smoothly instead of cracking or jumping at the transition point. The K-pop mixed-voice song analysis applies directly to this boundary regardless of voice type.

Delicate dynamic control

Several of his most-referenced lines shift in intensity within a single phrase — softening or opening up mid-line rather than holding one dynamic level. This depends on fine breath-flow adjustment, since dynamic shifts without matching airflow control tend to destabilize pitch. The K-pop high notes training guide includes progressive drills for combining dynamic control with register work.

How to Train Toward Sunghoon's Style

Step 1 — Find your comfortable key first

Run a range test from your lowest to highest comfortable note before attempting any Sunghoon song. Without a documented numeric range to chase, transpose songs to fit your own voice so you can focus on tone and dynamic control instead of pitch matching.

Step 2 — Study where the tone turns airy versus full

Pick one song — "Polaroid Love" or "XO" are good starting points — and listen for the exact lines where the delivery lightens into an airy color versus where it fills out. Identify the shift points before you try to reproduce them.

Step 3 — Build breath support before chasing an airy tone

An airy production needs more controlled airflow, not less. In Bloom Vocal, the breath exercises and A-1 (Breath Support Foundation) build the base needed so the airy tone stays pitched and stable rather than collapsing into a breathy whisper.

Step 4 — Train the falsetto-to-full-voice boundary

Work C-4 (Chest-to-Mix / Register Transition) with gentle glide exercises that connect falsetto and full voice at low-to-moderate volume. Gradually adjusting fold closure, rather than switching abruptly, is the mechanism behind his smooth movement across register boundaries.

Step 5 — Run an AI feedback loop on a single phrase

Record one 8-bar passage and use Bloom Vocal's AI coaching to score pitch accuracy, breath support, and register consistency. Compare the result to the original for airy tone control first, dynamic shading second — the AI flags habits like losing pitch stability when the airy quality thins out too far.

Check Your Cover with AI

Imitating a tone by ear has a ceiling: you can't reliably hear your own breath flow or register breaks while producing them. Upload a recording of a Sunghoon passage — the light verse of "Polaroid Love" or the dynamic shifts in "XO" — and Bloom Vocal's AI scores your pitch accuracy, breath support, register transitions, rhythm, and expression on a 1–5 rubric, then recommends the specific exercises to fix your weakest area first. It turns "that sounded a bit unstable" into "your airy tone lost breath support near the end of the phrase — drill the sustained-airflow exercises."
