KEFINE Klean SV IEM

KEFINE Klean SV In-Ear Monitors (IEMs)

The KEFINE Klean SV is the evolved Silver Version of the highly acclaimed Klean series, engineered for listeners who crave speed, clarity, and precision. Featuring a new-generation 10mm DLC (Diamond-Like Carbon) diaphragm dynamic driver, the Klean SV delivers a faster, tighter, and more resolving sound than its predecessor—without sacrificing musicality.

Designed with a dual-cavity driver structure, the Klean SV ensures excellent consistency across bass, mids, and treble, creating a well-balanced yet immersive soundstage. Whether you’re a detail-loving audiophile or a daily music enthusiast, this IEM offers exceptional transparency and control across the frequency range.

One of the highlights of the Klean SV is its three interchangeable tuning nozzles, allowing you to fine-tune the sound signature to your preference:

• Silver Nozzle – Balanced and natural

• Gold Nozzle – Neutral, transparent, and highly detailed

• Black Nozzle – Warm, smooth, and bass-forward

Built to last, the metallic alloy ear cavities are crafted using high-precision casting and polished for a premium silver finish. The ergonomic shell design follows the natural contours of the ear, ensuring long-term comfort and a secure fit.

KEFINE bundles the Klean SV with a high-quality silver-plated copper cable, featuring standard 0.78mm 2-pin detachable connectors. To suit different listening setups, the IEM is available in 3.5mm single-ended, 4.4mm balanced, and USB-C termination options, making it compatible with smartphones, DACs, DAPs, and desktop rigs alike.
