Kefine, in collaboration with Angel Ears, has introduced a special variant of its well-received Delci IEM, the Kefine Delci AE. Building on the success of the original Delci, which earned praise for its well implemented Harmanish smooth, musical presentation, the Delci AE comes equipped with a new dual-cavity 10mm dynamic driver featuring a DLC+PU diaphragm. This release is not a direct upgrade to the Delci but more of a alternative option for those who have not tried the Delci or also for those who have the OG Delci but want a newer variant in a already well tuned OG model. The AE delci model has a clean, crisp sound reproduction housed in a sleek, ergonomically designed aluminum alloy shell. But how does it fare in real-world use? Let’s dive in.
Unboxing and First Impressions
The Delci AE’s ear shells just like the OG Delci is crafted from CNC-machined aviation-grade aluminum alloy they actually put a sticker in the box saying so
its why the delci is one of the lightest metal iem i have and compared to some metal iems in the market that is acually made of zinc alloy which is more heavy and gets brittle in time. The Delci's clean minimalist styling really sets the Kefine design apart from the usual shiny glittering rainbow swirl chifi iems. The material not only gives the shells a durable feel but also keeps them remarkably lightweight at just 5.3 grams per earpiece. This lightweight design, coupled with the compact form factor, ensures a comfortable fit that can be worn for extended listening sessions without fatigue.
The packaging also includes two sets of replaceable tuning nozzles that allows users to customize their listening experience. The silver nozzle provides a warm, smooth sound signature, while the golden nozzle enhances the clarity and detail, catering to different musical preferences.
Kefine also bundled a high-purity 164-core cable with the Delci AE, featuring a mix of OFC (Oxygen-Free Copper) and silver-plated cores. The cable is soft and pliable, reducing microphonics and making it easy to manage during use. Available in 3.5mm and 4.4mm terminations, the cable caters to both standard and balanced outputs.

The Delci AE’s 10mm dual-cavity dynamic driver, featuring a DLC (Diamond-Like Carbon) diaphragm and PU suspension, delivers an impressive auditory experience. The DLC diaphragm is known for its lightweight and rigid properties, contributing to the pair’s ability to produce a clear, distortion-free sound.
Bass: The bass response on the Delci AE is deep and well-controlled, courtesy of the dual-cavity design. it is undeniably powerful but never overbearing. It has a clean, controlled presence that complements rather than overwhelms the music. Each bass note is defined with sharp leading edges, and the decay is quick yet natural, maintaining a clean tone that adds a sense of depth without any muddiness. It doesn’t overpower the other frequencies, allowing for a more balanced presentation. Whether it’s the resonating thwack of a bass guitar in rock music, jazz or the repeatetive bass thumping in electronic/techno tracks and some deep rumbling of a hiphop beats, the Delci AE handles it with precision without losing its fun musicality.
Mids: The midrange is my favorite part in the Delci AE its what i think sets the Delci series apart from the similarly tuned sets in its price bracket. Vocals are rendered with clarity and warmth. natural tone and timbre with a slight brightness in upper midrange giving the mids/vocals more details and vividness, The tuning seems to be aimed at those who appreciate a natural and lifelike reproduction of vocals and instruments. Listening to acoustic tracks on the Delci AE is a particularly immersive experience, with every strum of a guitar and variations in a vocal performance captured with accuracy, with the upper mids flows smoothly to the lower treble making the transition more flowless and cohesive.
Treble: The treble on the Delci AE is crisp and well-extended, providing plenty of detail without becoming harsh or fatiguing. The gold nozzle, in particular, enhances the treble, bringing out the finer details in high-frequency instruments and adding a touch of sparkle to the sound. its has a prefect balance of bright detail and natural timbre, make the overall treble natural, detailed and energetic.

Tuning Nozzles:
What set the Delci AE from the OG Deci is the inclusion of two swappable tuning nozzles.
The silver nozzle delivers a warmer, smoother sound signature, when using this nozzle i find it to have the closes sound to the OG Delci which I found perfect for most genres but specifically on Jazz, Rock, Pop etc... the silver nozzle rounds off the treble slightly, making for a relaxed listening experience that’s easy on the ears during long sessions.
The golden nozzle, on the other hand, is a different beast and my nozzle of choice paired with Divinus Velvet standard tips, this setup sharpens the treble and enhances the overall clarity, making it ideal for classical and instrumental music. The increased detail and brightness bring out the subtle variance in complex compositions but still retains the rumble and punchiness of the bass, overall the gold nozzle is a great choice for critical listening.
When i pair the gold nozzle with standard divinus velvets, The more i use this the more it sounds like ea500lm with similar tonality, timbre and technicalities but still retains the OG delci bass, a perfect balance of boomy and punchy bass we all love on the OG delci.

Technicalities:
Both the original Delci and the AE version exhibit similar technical strengths, though they share some limitations. The soundstage, while not expansive, creates a focused listening environment that allows for good instrument separation. Instruments are clearly defined, making it easier to pick out individual elements in a track, although the overall sense of space might feel somewhat constrained. Imaging is decent, with each sound element placed in its own distinct location, though it may not reach the levels of precision found in higher-end models, Delci compensates for it with total immersive and fun musicality which lets me get really immersed and lost in my music rather than analyzing each nuances in every track which i find very distracting just likje in some of my more technically tuned iems. the Delci AE delivers a performance that i find satisfying, which especially compliment its other strengths like the overall fun tonality of the both Delci models that focuses on musical enjoyment rather than showcasing technical capabilities.
The Kefine Delci AE exemplifies what thoughtful design and careful engineering can achieve in the world of in-ear monitors. It delivers a refined, versatile sound signature that can be customized to individual preferences with its swappable nozzles. The build quality is outstanding, offering durability without sacrificing comfort.
I’ve had the privilege of owning all of Kefine’s IEM models the Klanar Planar, DELCI, Delci AE and they’ve consistently impressed me with their superior build quality, minimalist yet classy design, and the distinctive Kefine house sound that perfectly suits my playlist.
If you’re in the market for a pair of IEMs that combine aesthetics, comfort, and excellent sound quality, the Kefine Delci AE definitely deserves a spot on your shortlist.
