Kefine Klean 10mm DLC Diaphragm Dynamic Driver Hi-Fi In-ear Earphones

KEFINE Klean – 10mm DLC Diaphragm Dynamic Driver IEM | Natural, Musical Tuning with Interchangeable Nozzles & Ultra-Lightweight Design

The KEFINE Klean is a premium single dynamic driver in-ear monitor that combines cutting-edge materials and thoughtful engineering for a natural, musical, and versatile listening experience. At its heart is a 10mm DLC (diamond-like carbon) diaphragm dynamic driver—one of the hardest and lightest materials in audio—delivering high-fidelity sound with exceptional detail, extended highs, transparency, and clean reproduction. The dual-cavity structure ensures consistent performance between left and right channels, resulting in powerful yet controlled bass, warm and rich mids, and smooth, non-fatiguing treble that feels engaging and lifelike across genres.

Key Features

• 10mm DLC diaphragm dynamic driver – ultra-high rigidity and lightness for fast transients, low distortion, detailed highs, and transparent clarity
• Dual-cavity driver design – guarantees perfect sound consistency and coherence between channels
• Two interchangeable nozzles – threaded system for easy swap; one for balanced/natural tuning, the other for a slightly different flavor (e.g., more warmth or clarity), plus solves clogged tube issues to extend IEM lifespan
• Ultra-lightweight & comfortable – only 5.3g per side (50% lighter than typical metal IEMs), CNC-machined single-piece aluminum alloy shells for premium feel and all-day ergonomic fit
• Premium silver-plated copper cable – 0.78mm 2-pin detachable, 108-wire construction (18 wires × 3 strands × 2 cores, 0.06mm per wire) for clean, transparent sound and wide treble extension
• Natural & musical signature – powerful bass, warm/rich mids, smooth/transparent treble—versatile for vocals, acoustic, pop, rock, and more
