KEFINE Delci AE IEM – Developed in Collaboration With Angel Ears

The KEFINE Delci AE is a next-generation in-ear monitor created in collaboration with Angel Ears, designed for audiophiles and music lovers who demand premium sound, comfort, and versatility. Featuring a 10mm dual-cavity dynamic driver with a DLC+PU composite diaphragm, the Delci AE delivers powerful bass, smooth mids, and crystal-clear treble with exceptional precision and low distortion.

Crafted with CNC-machined aluminum alloy shells, these IEMs are not only lightweight but also highly durable, offering all-day comfort at just 5.3g per earpiece. The replaceable tuning nozzles (silver and gold) allow you to switch between two unique sound signatures—warm and smooth for pop and vocals, or bright and transparent for classical and instrumental tracks.

The Delci AE comes bundled with a high-purity silver-plated copper cable using 0.78mm 2-pin connectors and available in 3.5mm or 4.4mm terminations, ensuring superior signal transmission and flexible pairing with a wide range of devices.

Whether you’re a stage performer, studio professional, or a dedicated audiophile, the KEFINE Delci AE offers a refined listening experience that balances power, detail, and versatility.
