KEFINE Delci 10mm DLC+PU Diaphragm Dynamic Driver IEMs

KEFINE Delci 10mm DLC+PU Dynamic Driver IEM Overview

The KEFINE Delci is a single dynamic-driver in-ear monitor built around a 10mm DLC+PU diaphragm and dual-cavity driver structure. The combination of Diamond-Like Carbon and PU materials is used in the diaphragm system, while the dual-cavity design helps KEFINE control the driver’s acoustic response.

Delci is also designed to remain lightweight despite its metal construction. Each earpiece weighs approximately 5.3g and uses a CNC-machined aluminum housing with a gunmetal finish. A detachable 0.78mm 2-pin cable, 3.5mm single-ended plug and relatively compact shell make it a practical wired IEM for music listening from compatible DACs, audio players, laptops and other headphone sources.

10mm DLC+PU Dynamic Driver

At the center of the Delci is a 10mm dynamic driver using a DLC+PU diaphragm structure. DLC, or Diamond-Like Carbon, provides a rigid diaphragm surface, while PU is incorporated into the composite driver structure. KEFINE combines these materials with a dual-cavity acoustic design.

This remains a single-driver IEM, so the full audible range is handled by one dynamic driver rather than a hybrid combination of dynamic and balanced-armature drivers.

Dual-Cavity Driver Structure

KEFINE uses a dual-cavity structure around the dynamic driver. The manufacturer highlights this architecture particularly in relation to the Delci’s low-frequency performance.

The published frequency response is 20Hz to 20kHz, with an impedance of 28Ω ±15% and sensitivity of 108dB ±3dB.

Lightweight CNC-Machined Aluminum Housing

The Delci uses a CNC-machined metal housing with a gunmetal finish. The aluminum construction gives the earphones a solid shell while keeping the weight at approximately 5.3g for each earpiece.

The low shell weight can be useful during longer listening sessions, although actual comfort and fit will still depend on individual ear shape and the selected ear tips.

0.78mm 2-Pin Detachable Cable

Instead of using a permanently fixed cable, the Delci features a standard 0.78mm 2-pin detachable connection. This makes it easier to replace the stock cable or use another compatible 2-pin cable later.

Connector compatibility should still be checked before purchasing an aftermarket cable because different IEMs can use different connector housings and pin arrangements.

164-Wire Copper Stock Cable

The supplied dual-color cable is constructed from 164 copper wires and terminates in a standard 3.5mm single-ended plug. Its specified length is approximately 1.2 metres ±0.2 metres.

The 3.5mm termination makes the Delci suitable for compatible headphone outputs on DACs, amplifiers, digital audio players and other audio sources. Phones without a headphone jack may require a compatible USB-C or Lightning audio adapter.

KEFINE Delci Specifications

Who Is the KEFINE Delci Suitable For?

The Delci is suited to listeners looking for a wired single-dynamic-driver IEM with a metal shell, detachable cable and conventional 3.5mm connection. Its 0.78mm 2-pin interface is also useful for people who prefer being able to replace or change their IEM cable instead of using a permanently attached design.
