Description

Kefine Klean SV is a premium high-fidelity wired in-ear monitor engineered for versatility and sonic precision, powered by a flagship-grade 10mm Diamond-Like Carbon (DLC) dynamic driver. Its ultra-rigid yet lightweight diaphragm delivers exceptional transient response with minimal breakup, producing powerful bass, rich mids, and transparent highs with incredible detail. A dual-cavity driver architecture paired with a high-efficiency N52 Neodymium magnetic circuit ensures linear motion and low distortion, while the unique screw-secured metal alloy housing provides a stable, resonance-free chamber and long-lasting durability. 

Featuring a tri-mode acoustic tuning nozzle system, users can instantly swap between balanced (Silver), transparent (Gold), or warm (Black) sound profiles to suit any genre. Complete with a high-purity silver-plated 0.78mm 2-pin cable available in 3.5mm, 4.4mm Balanced, or Type-C DSP options, the Klean SV offers a customizable, fatigue-free listening experience for audiophiles and gamers alike.

10MM FLAGSHIP-GRADE DLC DYNAMIC DRIVER

The Klean SV is built around a high-performance 10mm dynamic driver featuring a Diamond-Like Carbon (DLC) diaphragm. This material is renowned for being extremely rigid yet ultra-lightweight, ensuring high mechanical strength with minimal breakup. The result is high-fidelity sound reproduction with exceptional transient response, delivering powerful bass, rich warm mids, and transparent high-frequency extension with incredible detail.

TRI-MODE ACOUSTIC TUNING NOZZLES

To cater to diverse listening preferences, the Klean SV features a replaceable nozzle system with three distinct tuning profiles. The Silver Nozzles provide a balanced and natural signature; the Gold Nozzles are tuned for transparency, enhancing clarity and treble extension; and the Black Nozzles deliver a warm, immersive sound with richer bass response. The threaded design ensures quick, tool-free swapping while extending the earphone's lifespan by preventing wax buildup in the sound tubes.

DUAL-CAVITY DRIVER ARCHITECTURE & N52 MAGNETS

The internal acoustic structure utilizes a dual-cavity design that optimizes airflow and pressure management for linear driver motion. Powered by a high-efficiency N52 Neodymium magnetic circuit and a lightweight Daikoku CCAW voice coil, the system delivers consistent performance with low distortion. This architecture ensures clean separation between instruments and a natural soundstage that handles complex tracks with ease.

PRECISION METAL ALLOY CAVITY WITH SCREW-SECURED DURABILITY

The earphone housing is crafted using advanced metal alloy casting, ensuring a stable, resonance-free acoustic chamber. Unlike glued assemblies that may fail over time, the front and back housings are mechanically secured with a screw design. This robust construction guarantees long-term durability and structural integrity while maintaining a premium, exquisite finish that resists wear.

HIGH-PURITY SILVER-PLATED CABLE SYSTEM

The Klean SV ships with a premium silver-plated copper cable designed for clean, transparent signal transmission. The cable consists of 2 cores with a total of 108 individual wires (18 wires x 3 strands per core), offering low impedance and wide frequency extension. The standard 0.78mm 2-pin detachable interface provides wide compatibility for future upgrades and easy maintenance.

VERSATILE CONNECTIVITY WITH TYPE-C DSP OPTION

Catering to all source devices, the Klean SV offers multiple plug options including standard 3.5mm Single-Ended and 4.4mm Balanced. A specialized USB-C version is available featuring a built-in DSP (Digital Signal Processor), high-quality microphone, and in-line volume controls, making it a perfect all-in-one solution for mobile gaming and calls without requiring an external DAC.

ERGONOMIC COMFORT & COMPLETE ACCESSORY SUITE

Designed to match the natural contours of the human ear, the 10g lightweight shells provide a comfortable, fatigue-free fit for extended listening sessions. The comprehensive package includes a durable hard carrying case, six pairs of silicone eartips (L/M/S) for a perfect seal, and a quality certificate, ensuring a premium unboxing experience.
