Kefine Delci AE VS Simgot Supermix 4

Youtube Video Summary

Kefine Delci AE (Angel Ears Edition) takes the already beloved Delci formula and packages it in a more refined way. The CNC-machined aluminum shells feel solid yet lightweight, with excellent finish, dual vents that prevent driver flex and pressure build-up, and a comfortable ergonomic fit that allows long sessions without fatigue. The bundle adds a soft but sturdy pocket case, two sets of narrow-bore silicone tips and two screw-in nozzles (silver and gold), plus the option for a balanced 4.4 mm cable, making the overall package feel thoughtfully upgraded over the original version.

With the silver nozzle, Delci AE keeps the same very pleasing U-shaped tonality that made the original so popular. Sub-bass has satisfying rumble and slam without becoming boomy, the bass shelf slopes down cleanly into the lower mids, and the result is a warm-leaning signature with plenty of note weight and organic tone on guitars, saxophones, strings and male vocals. Upper mids and lower treble are lifted enough to bring out clarity and air for female vocals and higher-pitched instruments, yet they avoid shout and harshness most of the time. Treble can show a touch of spiciness on some tracks, but generally stays controlled while providing good detail, sparkle and air. Isolation is surprisingly strong for a vented shell, and the soundstage is wider than average, adding to a very immersive and relaxing listen.

Technically, the AE with the silver nozzle offers a subtle but audible step up over the original Delci, with slightly tighter bass, cleaner imaging and a modest bump in detail retrieval, on the order of a 5-10% improvement rather than a transformation. Swapping to the gold nozzle pushes technicalities much further, with a large increase in perceived detail, clarity and separation in the upper mids and treble, but this comes with a trade-off of thinner note weight and a more energetic, sometimes shouty or bright presentation on busy modern tracks. Compared to slightly more expensive sets like Dunu Titan S2 or Simgot EA500 LM, Delci AE does not reach the same level of resolution and bass texture, yet as a complete package, with strong tuning, wide stage, excellent comfort and build, balanced cable option and nozzle flexibility, it remains an easy recommendation for listeners who want a warm, natural daily driver in this price bracket.

The SIMGOT SuperMix 4 pairs a lightweight metal and resin shell, good isolation and a decent cable with a mostly Harman-style, vocal-forward tuning. Bass comes across as clean, clear and reasonably detailed with no bleed into the mids, but slam, rumble and physical impact are noticeably softer than expected, especially compared with the cheaper EA500 LM and other sets on a similar curve. The low end feels slightly below average in attack and weight, so even hip-hop and pop tracks that usually hit hard come across as polite and less engaging.

The midrange is clean and clear with a strong focus on female vocals and upper mids, yet the 3–6 kHz region can easily drift into a shouty or shrill character depending on volume, genre and recording, leading to listening fatigue on K-pop, J-pop, rock and brighter material. Treble is detailed, airy and full of shimmer, but the overall presentation does not feel fully natural or cohesive, becoming harsh when the volume is raised and a bit strange when kept low. Technicalities are strongest in the upper mids and treble, while soundstage size is essentially average for the price range.

In direct comparisons, sets like EA500 LM, Nova, AFUL Explorer and Binary Chopin offer more convincing bass slam, more natural tonality and a more engaging, coherent presentation at similar or even lower prices, making the SuperMix 4 feel more like a sidegrade than a true upgrade around the $150 mark. SuperMix 4 provides slightly higher perceived technicalities in specific upper-mid and treble regions, but this comes at the cost of greater fatigue and a very smooth, almost boring overall character that struggles to excite across diverse genres. For most listeners, alternatives in this segment give better value, leaving SuperMix 4 mainly for brand loyalists who specifically want a cleaner, brighter, vocal-focused take and can tolerate the sharper ear-gain region.

Supermix 4 emerges as the standout of Simgot’s quartet for both fit and build, pairing a classy brushed bronze faceplate with the most refined tuning of the group. As a quad-brid, it delivers superior cleanliness, imaging, and depth perception versus EM6L, EA1000, and EA500LM, with tighter separation and more micro-detail; its presence region feels a touch more laid-back than EA1000, keeping gunshots from turning shouty. Footsteps could be slightly more elevated for sweaty lobbies, but that’s easily addressed with EQ while preserving the set’s natural balance.

Across titles it’s the most dependable all-rounder: in Valorant, the added cleanliness and precision outclass EA500LM (bloated, spicy gunshots) and nudge ahead of EM6L/EA1000; in Rainbow Six Siege, clarity, separation, and positional cues make it the clear pick. Call of Duty is closer—EA500LM is a solid budget choice and EA1000 can get intense—but Supermix 4 still pulls more footstep detail while staying composed; in Apex Legends it trades blows with EM6L yet edges ahead with extra information retrieval. Overall verdict: Supermix 4 wins, with EM6L in second, EA1000 around B-, and EA500LM around C+; a clean, precise, and thoroughly engaging pick for competitive and casual gaming alike.

SIMGOT Supermix 4 comes out swinging: a quad-brid with both planar and PZT drivers that somehow sounds buttery smooth and shockingly coherent—more like a single driver than a parts bin. Upper-mids and treble sit neutral and refined, avoiding the usual glare; tuning reads as Harman 2019 done right—what feels like endgame Harman. Versus sets like Supernova/Nova/Chopin, the SM4 brings cleaner extension, higher resolving power, and a smoother, more polished treble where cymbals and consonants land naturally. Note this is a pre-production unit, so final tuning may still shift.

Bass quantity measures lower than some peers, but that puts the low end in the background and boosts separation, layering, and transient clarity; texture is tidy, impact respectable, and decay well-judged. Vocals are a highlight—accurate, balanced, complete in extension, and consistently non-fatiguing. Treble adds a sprinkle of liveliness without turning sharp. In A/Bs: it feels like a cleaner, more energetic Origin; a smoother, more technical all-rounder than CK LVX/Pula (though those keep a fuller, dreamier flavor); trades blows with Dusk (Dusk hits harder and runs brighter, SM4 wins mid/upper-mid detail and vocal completeness); and out-separates Hype 4 while Hype 4 remains the bigger, bassier fun pick. As an all-rounder this is top-tier; if priced around Dusk/Hype 4 it’s a strong value, while a ~$500 tag would push it into diminishing returns.

Kefine Delci AE comes in around 69 dollars with a regular price closer to 89, packaged with a simple but useful case, solid tips and a soft two pin cable that suits the new silver shell. The all metal body is compact and comfortable, giving an easy fit that works well even for smaller ears. Overall build, ergonomics and accessories feel very secure for the price and let the Delci AE disappear so the music can take center stage.

With the silver nozzle installed, the Delci AE follows a mostly neutral but slightly warm and engaging curve that brushes up against a mild V shape. Bass has very good dynamics and extension, hitting with satisfying weight while staying controlled, but the extra energy in the low mids does add some thickness and a bit of bass bleed that can lightly cloud lower mid clarity. What stands out is the midrange: vocals and instruments sound very natural and organic, with more detail and clarity than the original Delci, and the treble keeps that same natural tone with a touch of edge for definition, more refinement, a slightly more open stage and better separation and imaging, only really held back by a wish for just a little more upper air.

Switching to the gold nozzle shifts the energy upward, giving a brighter, more vocal forward and even more resolving presentation that still preserves the natural character of the mids. Bass is a little leaner while voices step forward in the mix without becoming shouty, and the whole presentation opens up further for those who want clarity and vocal focus over warmth. Taken together, the two tunings make Kefine Delci AE a clear top pick under and even slightly above 100 dollars, with what is described as the best single dynamic driver implementation and one of the best tunings in this range, preferred over sets like AFUL Explorer, Titan S2, EA500 and even the original Delci, and it is an easy recommendation as a starting point for anyone looking to get into the hobby.

Build and comfort are front-and-center: a cozy shell with a metal faceplate, excellent ergonomics, and easy tip fitment. The red/blue two-pin sockets and the gunmetal cable add a premium touch, while the case is the familiar, functional Simgot pouch. Hype is warranted at least on construction—this is the most comfortable Simgot shell in the lineup so far.

Sonically, Supermix 4 follows a Harman-style curve with clean channel matching, solid resolution, and bass that balances sub-bass presence with controlled mid-bass. Treble can “touch the sun”—slightly bright on certain tracks—and the very low impedance makes it source/tip sensitive; tip rolling and even a basic Apple dongle often settle it down. Technicalities are strong for the price: clarity, shimmer on cymbals, and lifelike guitars impress, though some will crave a smoother top end.

Against peers, it surpasses EW200 in refinement and comfort and feels like a cleaner, easier-to-live-with replacement for EM6L. Compared with AFUL Explorer, this is the more forward/bright take versus Explorer’s laid-back vibe; versus CCA Hydro, vocals are steadier while Hydro punches harder down low. Kiwi Ears Quintet shows similar intent but has quirks around 10 kHz; DaVinci is a touch more refined yet pricier, and some will prefer Supermix 4’s shell and value. Net result: a strong recommendation for listeners wanting a comfortable, versatile, mildly vivid IEM that competes above its bracket—great for music and even gaming—so long as a hint of brightness is acceptable.
