Kefine Delci – Unassuming Nightingales in Their Price Category

When I headed to the post office to grab another pair of budget headphones for a review, I wasn’t expecting anything special. But when I got the box with the Kefine Delci, I immediately noticed their plain look and minimalist design. However, after unboxing, I realized that behind the modest exterior was a true audio gem. These single-driver dynamic wired in-ear headphones turned out to be absolute nightingales in their price category, capable of impressing even the most demanding audiophile.

What Kefine offers in the Kefine Delci wired IEMs

The Delci buds are packing a 10mm dynamic driver with a diaphragm made of DLC and PU composite material (diamond-like carbon and polyurethane).

Each earbud weighs just 5.3g.

The housing is made from CNC-machined aluminum alloy.

The dual-color detachable cable consists of 164 copper wires (54×2 + 28×2) with 0.78mm 2-pin connectors and a 3.5mm jack.

The package includes 7 pairs of eartips and a hard carrying case.

Sound of the Kefine Delci wired in-ear headphones

To test the sound I used Questyle QP1R player. I evaluated the sound taking into account the price.

• Overall presentation: melodic headphones with good detail and emotionality.
• Bass: robust and substantial with fairly good attack and decay handling. In bass-heavy tracks, there’s plenty of it, sure to please bass lovers. The sub-bass is well-defined and detailed. Mid-bass is extended and clear, slightly overshadowing the mids in volume.
• Mids: pleasant, natural, and sufficiently detailed. Male and female vocals sound very good, distinctly reproduced without overlapping. They might lack a bit of emphasis and emotion, but the vocals sound natural without a hint of synthetic timbre. Brass instruments are not as emphasized and, like the vocals, slightly muted, but still perceived naturally.
• Highs: in tracks with pronounced highs, there’s a sense of saturation. They try to brighten the sound without overshadowing the other frequency ranges. Very discernible, with proper emphasis, but not piercing.
• Detail retrieval: at a decent level, above average for its price range, you can hear the crackles of a vinyl record and imperfections in the recording, as well as performance nuances.
• Soundstage: fairly spacious, with a sense of width and depth in image rendering and performer placement.

Conclusion: The sound signature is clearly recognizable, with a pronounced V-shaped frequency response. They will appeal to both bass lovers and those who enjoy emotionally charged tracks.

Comparison with competitors

It’s tempting to compare them with MOONDROP MAY, but those are hybrids (1DD+1PL), whereas we’re dealing with pure single-driver dynamics, so it’s more fitting to compare them with Truthear Gate or HIFIMAN RE400, although they aren’t in the same price range, as well as INTUAURA Plume or Luster. Probably the best comparison is within their own price category:

• MOONDROP MAY sound more emotional compared to Kefine Delci. However, they lose out on technicality; the Delci has more precise and detailed sound, and vocals in the midrange are more natural and lifelike.
• AFUL MagicOne sound cleaner and more technical in the midrange but falls short in the rest of the range. Kefine Delci comes across as more cohesive and musical.
• INTUAURA Plume is definitely a basshead model, but that’s where its advantages end.
• INTUAURA Luster sounds better than Kefine Delci in the mids and highs, but I felt it lacked resolution in the low end.

Design, kit, and comfort

The headphones come in a black box with a pic of the buds on the front and the specs on the back. No fancy stuff or anime characters, which is impressive.

• Headphones: a low-key design with a metal build and plain brown color—like “grey mice.” On the front side, there’s a black circle with the Kefine logo, and a tiny compensation hole on the back. The nozzle has the right angle and is covered with a cool silver mesh that looks like a whirlpool. Surprisingly, the faceted housing fits comfortably in the ear and doesn’t cause discomfort during long listening sessions.
• Cable: Looks thin and flimsy but is actually solid, not messing with the sound profile like the TIN HIFI P1 Max. It’s color-matched to the headphones, free of microphonics, and has quality connectors. Props to them for marking the L/R sides on both the buds and the cable.
• Ear tips: Two sets with different nozzle diameters. Three pairs with wide openings (S, M, L) and four pairs with narrow openings, all in different sizes.
• Case: Made of good-quality faux leather, the right size, with a gold Kefine logo.

Conclusion: the IEMs sit comfortably in the ear, the metal housing has a slight cooling effect. The bland, angular design of the housings didn’t impress me, so I docked a point. The accessory pack is minimal and sufficient.

Conclusion

KEFINE DELCHI, at first glance, seem unremarkable, but they turned out to be a real gem. They showed mature and quality sound for their price range. I especially liked their even, natural sound across the frequency range, and well-accented emotions. The only downside is the modest design, lacking originality.

These headphones are great for both music lovers and audiophiles, thanks to their interesting and balanced sound. It’s hard to find a genre that the DELCHI can’t handle. In their price range, they are definitely favorites.

My verdict: great value for the money.
