KEFINE Quatio IEM

KEFINE Quatio Hybrid IEM – Precision-Tuned Versatility, Now in 2DD+2BA Hybrid Format

Discover KEFINE’s first hybrid IEM – the Quatio, a premium 2DD+2BA configuration built to deliver a rich, immersive, and musical listening experience. Designed for audiophiles seeking both technical finesse and tuning flexibility, the Quatio features a quad-driver architecture with two dynamic drivers (10mm DLC + 8mm PU+LCP) and dual balanced armatures, delivering exceptional clarity, impactful bass, and refined highs.

What sets the KEFINE Quatio apart is its dual-way crossover system—a combination of physical acoustic channels and electronic crossover boards, ensuring each driver is precisely tuned for optimal performance. Whether you're enjoying jazz, classical, EDM, or vocal-centric tracks, the three interchangeable tuning nozzles (Warm, Balanced, and Neutral) allow you to tailor the sound to your preference.

Housed in CNC-machined aluminium alloy shells, the Quatio combines sleek aesthetics with superb ergonomics. Each shell is polished, anodised, and crafted with ultra-fine tolerance (0.01mm) for a snug, fatigue-free fit.

Bundled with a high-purity silver-plated copper cable, this IEM also features a modular plug system that supports both 3.5mm single-ended and 4.4mm balanced outputs—perfect for pairing with portable DACs and players.

Whether you're a seasoned audiophile or a passionate newcomer, the KEFINE Quatio offers a complete, adaptable, and high-resolution listening experience like never before.
