KEFINE Delci AE 10mm DLC+PU Dynamic Driver In-Ear Earphone – Dual Tuning Nozzles, CNC Metal Shell, Detachable 2-Pin Cable at GearBaba
For audiophiles and music lovers seeking exceptional sound quality and a customizable listening experience, the KEFINE Delci AE 10mm Driver In-Ear Earphone stands as a remarkable option. This upgraded version of the acclaimed Delci, developed in collaboration with Angel Ears, combines advanced driver technology, premium build materials, and innovative tuning features to deliver a truly immersive audio journey. Whether you’re a discerning listener, a casual music enthusiast, or a mobile gamer, the Delci AE is engineered to impress. Explore this high-performance in-ear monitor in our Earphones & Headphones category at GearBaba.
The KEFINE Delci AE is built around a newly developed 10mm dual-cavity dynamic driver featuring a sophisticated DLC (Diamond-Like Carbon) and PU (Polyurethane) composite diaphragm. The DLC material provides exceptional rigidity and lightness, ensuring high-speed sound transmission, low distortion, and transparent, bright highs. The PU suspension material complements this by enhancing bass response, delivering powerful, deep, and captivating low frequencies, resulting in a rich and lively sound signature. This combination ensures crystal-clear, high-fidelity sound reproduction across a wide frequency range (20Hz-20kHz).
A standout feature of the KEFINE Delci AE is its interchangeable tuning nozzles. The package includes two sets of nozzle filters: a silver filter that provides a warm, smooth, and musical sound ideal for Pop music, and a golden filter that offers higher resolving power, enhanced brilliance, and transparency in the treble, making it suitable for classical and instrumental music. This allows users to easily switch between sound profiles to match their preferences or the genre of music they’re listening to. The threaded nozzles also simplify maintenance and prevent blockages.
The earphone shells are crafted from high-quality aviation-grade aluminum alloy through a precise CNC machining process. This not only results in a durable and scratch-resistant housing with an elegant gunmetal finish but also makes the Delci AE incredibly lightweight, weighing just 5.3 grams per side. This lightweight and ergonomic design ensures an extremely comfortable fit for extended listening sessions.
The KEFINE Delci AE comes with a high-purity detachable cable featuring universal 0.78mm 2-pin connectors. This allows for easy cable upgrades and replacements. The stock cable is a dual-color design composed of 164 wire cores (72 strands of 0.05mm Oxygen-free Copper (OFC) and 92 strands of 0.06mm Silver-plated Copper (SPC)). This carefully selected cable enhances the sound presentation with a balanced tonal profile, clear sound, and transparent response. The cable is typically available with a 3.5mm single-ended termination, with some retailers offering a 4.4mm balanced option.
The KEFINE Delci AE offers an impedance of 28Ω±15% and a sensitivity of 108dB±3dB, making it relatively easy to drive with most portable devices while providing ample loudness and detail. The rich accessory package includes a hard carrying case and six pairs of high-quality silicone ear tips (three bullet-shaped for enhanced bass and three bowl-shaped with wider openings for a more transparent sound).
