Hear the Final Master as the Artist Intended
FLAIR isn’t made for the stage—it’s crafted for music lovers. It brings you closer to the sound inside the artist’s mind: the final master they envisioned. Rediscover familiar melodies with new depth and emotion.
4-Driver High-Resolution Acoustic System
FLAIR features a 4-way configuration with a nano carbon dynamic driver and three balanced armatures, designed to reveal every layer of emotion and spatial depth in the music. Vocals, strings, and intricate spatial cues flow naturally and effortlessly—nothing is exaggerated, nothing is missing.
LiveSound Vented Resonance Design
Inheriting ACS’s core acoustic technology, FLAIR uses a LiveSound filtering structure and vented chamber to relieve inner ear pressure, reduce fatigue, and maintain an open, breathable soundstage. The result: lighter, more dimensional music with exceptional listening comfort.
A Monitor Built for Music Enthusiasts
FLAIR avoids over-colored “pleasant tuning” and doesn’t aim for aggressive stage-forward sound. Instead, it takes the studio’s final master as its reference, letting you hear what the artist truly meant to express. Ideal for long sessions, deep listening, and discerning taste.
Minimalist Design, Secure and Comfortable Fit
With a white housing and rose gold mirror-finish faceplate, FLAIR embodies refined simplicity. Its ergonomic structure is shaped by extensive ear mold data, providing near-custom comfort and stability in a universal shell.
Your Ears Deserve a Complete Sound
FLAIR is a high-end universal IEM that borders on professional, designed not to impress, but to stay true. It captures the subtleties that other earphones miss—not for the sake of flashiness, but for honesty, not for glamour, but for truth. It’s made for those who genuinely want to understand music.
Experience the True Depth and Detail of Music
Powered by a custom 8mm nano carbon diaphragm dynamic driver and three precision-tuned balanced armatures, FLAIR separates low, mid, upper-mid, and ultra-high frequencies with clarity, delivering a rich and detailed soundscape.
