KEFINE Klean SV 10mm Dynamic Driver IEM Earphone

Description

  • The all-new Kefine Klean SV (Silver Version) is the upgraded successor to the highly acclaimed Klean series. Featuring a newly developed 10mm DLC (Diamond-Like Carbon) diaphragm dynamic driver, the Klean SV is engineered to deliver faster transients, tighter bass control, and higher resolution compared to its predecessor. The upgraded tuning provides a cleaner, more refined, and highly resolving sound signature designed for audiophiles who value clarity and detail.
  • At the heart of the Klean SV is its advanced DLC diaphragm. Diamond-Like Carbon is known for its exceptional rigidity and lightweight properties, allowing the driver to respond quickly and accurately. This results in crisp treble extension, controlled and punchy bass, and clear, natural vocals. The overall presentation is immersive, detailed, and well-extended across the frequency range, offering a truly high-fidelity listening experience.
  • The Klean SV adopts a dual-cavity dynamic driver structure, which enhances acoustic stability and consistency. This design helps maintain proper balance across lows, mids, and highs while reducing unwanted distortion. The three-frequency response is carefully tuned to deliver a clean, balanced, and engaging sound profile suitable for various music genres.
  • One of the standout features of the Klean SV is its interchangeable tuning nozzle system, allowing users to switch between three distinct sound profiles. The Silver nozzle provides a balanced and natural sound signature. The Gold nozzle offers a more neutral and transparent presentation with enhanced detail retrieval. The Black nozzle delivers a warmer sound with stronger bass impact and smoother treble response. This flexibility allows listeners to customize their audio experience according to personal preference.
  • In terms of build quality, the Klean SV features metallic alloy ear cavities crafted using a high-precision casting process. The housings are polished for a premium finish and joined securely for durability and structural stability. The ergonomic shell design follows the natural contour of the ear, ensuring a comfortable fit for extended listening sessions. Unlike the original Klean model, the Klean SV comes in a refined silver finish.
  • The earphones are bundled with a high-purity silver-plated copper cable designed to ensure clean and transparent signal transmission. The cable features a 2-core configuration with three strands and 18-wire conductors per strand, totaling 108 wires. It adopts a standard 0.78mm 2-pin detachable connector system and is available in 3.5mm single-ended, 4.4mm balanced, and USB Type-C termination options for broad compatibility.
  • Packed with premium accessories and advanced acoustic engineering, the Kefine Klean SV delivers a highly detailed, customizable, and immersive listening experience, making it an excellent choice for music enthusiasts seeking next-level clarity and performance.
