KEFINE Klean SV 10mm Dynamic Driver In-Ear Earphone

The all-new KEFINE Klean SV (Silver Version) establishes itself as a benchmark in the budget audiophile space. Engineered as the direct, upgraded successor to the highly acclaimed Klean series, this In-Ear Monitor (IEM) introduces a newly refined tuning architecture and a striking metallic alloy finish designed specifically for listeners who demand pristine audio precision without a premium price tag.

Advanced 10mm DLC Diaphragm Dynamic Driver

At the absolute core of the KEFINE Klean SV is its next-generation 10mm dynamic driver utilizing a full Diamond-Like Carbon (DLC) diaphragm. Renowned in high-end audio engineering for its immense structural hardness and incredibly lightweight properties, the DLC material allows the driver to respond with fast transient speeds.

This mechanical efficiency results in remarkably tight, punchy bass response, well-extended treble energy, and an exceptionally clean background that lets complex instrument arrangements breathe naturally.

Customizable Audio with Three Interchangeable Tuning Nozzles

The KEFINE Klean SV features a threaded, interchangeable nozzle tuning system that physically transforms the frequency delivery across three distinct sound signatures:

• Silver Nozzles (Pre-installed): Delivers a beautifully balanced, natural, and highly coherent sound signature ideal for daily all-rounder listening.

• Gold Nozzles: Pushes a transparent, neutral acoustic profile that emphasizes micro-detail retrieval and crisp upper-mid frequencies—perfect for vocal tracks and acoustic sets.

• Black Nozzles: Shifts the sound into a warm, deeply immersive profile, adding sub-bass depth, impactful mid-bass punch, and a smoother treble roll-off for fatigue-free listening.

Dual-Cavity Engineering and Premium Metallic Build

Acoustic consistency is achieved through a precisely calculated dual-cavity internal structure. This dual-cavity design stabilizes internal air pressure, lowering harmonic distortion across all frequencies while maintaining a sharp stereophonic center image.

Externally, the KEFINE Klean SV features a robust design. Each earpiece housing is precisely carved via a high-precision casting and polishing process out of high-grade aluminum alloy. The front and rear shells are joined securely via a physical screw, guaranteeing excellent structural durability while matching the natural contour of the human ear for a stable, comfortable fit during long hours of casual listening or critical studio tracking.

High-Purity 108-Core Cable Architecture

To keep your audio crisp and transparent, KEFINE bundles the Klean SV with a specialized 2-core silver-plated copper stock cable. Each core contains 3 individual strands, with 18-wire conductors per strand, totaling 108 wires. The cable adopts standard 0.78mm 2-pin connectors and is available in multiple termination variants—including 3.5mm single-ended, 4.4mm balanced, and USB Type-C configurations—so you can connect straight to your modern devices without extra adapter dongles.
