Kefine Delci DLC+PU Diaphragm Dynamic Driver HiFi Wired IEM

The Kefine Delci features a 10mm dynamic driver with a DLC (Diamond-Like Carbon) and PU composite diaphragm, delivering high-resolution audio with balanced bass response, aided by its dual-cavity design. The earpieces are CNC-machined from lightweight aluminium alloy, weighing only 5.3g per side—half the weight of typical metal-injection models—for extended comfort. The housing undergoes polishing and anodizing for durability, finished in a gunmetal shade for a refined look.

The driver combines DLC for precise highs and PU for natural, resonant lows, ensuring clarity without harshness. Key technical elements include an N52 magnet, dual-cavity acoustics, and Daikoku CCA wiring. The included dual-braid cable consists of 164 high-purity copper strands (54x2+28x2), tuned for warmth and detail. A 0.78mm 2-pin detachable interface allows for cable upgrades, and the package includes six pairs of eartips (two styles: bass-focused bullet tips and UV-coated bowl tips for enhanced clarity) alongside a hard-shell case.

The Delci offers a well-tuned, technically competent sound with a focus on balance and comfort. Its build quality and modularity stand out in its class, though bass depth may lag behind competitors prioritizing low-end impact. A solid choice for nuanced listening at this price.
