Design
Delci comes with alloy shells in a gunmetal grey colour. They’re fairly low-key with a raised logo on the faceplates being the only adornment. There are 2 small vents on the inner side of the shells. The IEMs have standard 2-pin sockets and nozzles with average width and protective metal mesh covers.
The comfort is great for my ears and suitable for all-day listening. Passive noise isolation is pretty good, so you can enjoy your music without distraction.
The included OFC cable is high-quality for a $50 IEM. It has lightweight metal components that perfectly match the colour of the housings. The cable is supple and free from distracting microphonics.
Sound
Gear used for testing includes the HiBy Digital M300, SMSL DO300EX and FiiO KA17. Delci is an efficient IEM so you can use it with any source, including straight out of a smartphone.
Delci boasts a U-shaped but well-balanced sound signature that combines dynamism and vigour without inducing listener fatigue. Its lively yet accurate presentation captivates with its energetic delivery and safe tuning.
Bass
There’s a good balance of sub-bass authority and mid-bass punch with a linear transition between both. The bass has a physicality and robust impact, yet it avoids any smearing or veiling of the midrange.
It’s a bass that can exhibit distinct layers and subtle vibrations without being overpowering or distracting.
Midrange
The midrange is mostly neutral with some underlying warmth carried over from the bass. This gives vocals and instruments good articulation but also a natural note weight. In other words, it’s a good blend of accuracy and richness.
The upper midrange is vibrant but never shouty so there’s nothing to fear when it comes to electric guitars and belting female vocals. Delci is proficient at conveying the attack and initial impact of musical notes, adding clarity and definition.
Treble
The treble performance of the Kefine Delci demonstrates precision and transparency, expertly reproducing intricate details in the music. With ample airiness, it creates an expansive soundstage, allowing instruments and vocals to resonate naturally.
The Delci’s treble extension is excellent, reaching into the upper registers to deliver sparkle and spaciousness. Its shimmering overtones add refinement so every note scintillates with pristine clarity.
Soundstage & Technicalities
Delci has fantastic instrument separation for a budget 1DD IEM which helps it create an organized soundstage with a black background.
Verdict
Simply put, the Kefine Delci is currently one of the best sub-$100 IEMs out there. It has a solid no-nonsense design and comes with a good stock cable. Most importantly, it sounds great with its balanced yet bold and technically adept presentation. Recommended.
