Key Features - DLC meets Dual-Cavity
Premium 10mm DLC Diaphragm Dynamic Driver
The entire diaphragm is crafted from cutting-edge Diamond-Like Carbon (DLC)—one of the hardest and lightest materials available in audio today. This advanced material provides superior mechanical strength for high-fidelity reproduction with incredible detail retrieval. Enjoy extended high frequencies that sound transparent, clean, and fatigue-free, while maintaining precise control across the spectrum.
Dual-Cavity Driver Structure
The innovative dual-cavity design ensures consistent sound performance between left and right earpieces, delivering a cohesive, balanced listening experience with natural timbre and imaging.
Natural & Musical Sound Signature
Experience powerful, impactful bass that adds energy without muddiness; warm, rich mids that bring vocals and instruments to life with emotional depth; and smooth, extended treble that sparkles with air and transparency. The tuning strikes a perfect balance—mildly V-shaped yet highly musical and versatile for genres from pop and rock to classical and electronic.
Three Interchangeable Tuning Nozzles
Customize your sound effortlessly with three unique nozzles (each featuring distinct tuning fabrics):
- Achieve brighter, more detailed highs over the OG for analytical listening
- Opt for warmer, bass-emphasized profiles for immersive fun
- Or enjoy the balanced default for all-around excellence Threaded nozzles make swapping quick and secure. Plus, they help prevent blockages from earwax, extending the lifespan of your IEMs and keeping performance optimal.
Ultra-Light & Comfortable CNC Aluminum Design
Weighing just 5.3g per side (half the weight of many metal IEMs), the housings are precision-machined from a single block of aluminum alloy via CNC. This results in one of the lightest metal-shell IEMs on the market—perfect for all-day comfort with minimal fatigue, secure fit, and premium feel.
High-Quality 2-Pin Detachable Silver-Plated Copper Cable
Equipped with a premium silver-plated copper cable for enhanced clarity and treble extension:
- 18 strands of 0.06mm wire per core
- 3 cores per strand
- Total of 108 wires (18 × 3 × 2) The thick, high-purity construction reduces distortion, improves transparency, and pairs excellently with the DLC driver for a clean, airy presentation. Detachable 0.78mm 2-pin connectors allow easy upgrades or replacements.

Klean SV Q&A
Q: How does the sound signature compare to the original Kefine Klean?
A: The SV is described as a "cleaner, more disciplined" take — reduced warmth in the bass, improved separation, better detail, more airiness, and dynamics without losing musicality. It aims for natural, powerful bass, warm/rich mids, and smooth/transparent treble. Many call it more refined and less colored overall.
Q: Is it easy to drive?
A: Yes — low impedance and high sensitivity mean it works well straight from phones, laptops, or dongles. No amp required, though a balanced 4.4mm cable + decent source can bring out more dynamics.
