Foreward:
I'm grateful to Pulkit (@gadgetgod) for providing me with this unit as part of the audition tour. After the release of its affordable and unique sounding iem the Klanar, Kefine is back with another IEM. Its a
single dynamic driver with 10mm DLC+PU diaphragm. Let's dig deeper on its build and my sound impressions.
Please Note: I lack the comprehension of audiophile jargon so I will try to explain my review like a 9 year old to avoid ambiguity in my review.
Build:
The Build is light and comfortable making it sit on the ears for longer sessions. The shell is light which weighs around 5.3 grams, and the finishing feels premium. The case and tips are decent for the asking price but the braided cable quality is above par. My review unit had the 3.5mm cable but I never felt the need for a balanced 4.4 cable. Read my sound impressions to know why..
Gear used:
Driveability 5/5
Delci can be easily driven from any source, and even from my Samsung M51's 3.5 headphone jack. However, with a good source it scales pretty well which shows the driver's versatile nature.
Sound:
To describe the sound I would say that the Delci has an overall warm presentation with a fun and engaging high end. That's not it. Keep reading to find out more.
Bass : 5/5
Sub Bass Depth and Rumble
Testing sub-bass depth and rumble in an IEM requires tracks that feature deep bass frequencies and powerful sub-bass elements.
Control and Tightness
To test bass control and tightness in an IEM, you’ll want tracks that feature well-defined basslines and controlled low-frequency elements.
Mid Bass Punch and Slam
Testing mid-bass punch and slam in an IEM requires tracks that emphasize the lower frequencies with impact and depth.
Mids: 3/5
Lower mids: Body and Warmth
To evaluate lower mids body and warmth in an IEM, you'll want tracks that feature rich vocals, acoustic instruments, and low-register instruments like guitars and cellos.
Upper Mids - Clarity and Detail
To test upper mids clarity and detail in an IEM, you'll want tracks that feature prominent vocals, guitars, and other mid-range instruments with intricate textures and nuances.
Midrange Balance and Timbre
Testing midrange balance and timbre in an IEM requires tracks that showcase a variety of instruments and vocal performances across the midrange spectrum.
Overall Midrange Performance:
Treble: 4/5
Treble Extension - Air and Brightness
Testing treble extension and brightness in an IEM requires tracks that feature prominent high-frequency elements such as cymbals, hi-hats, and vocal sibilance.
Treble Detail and Resolution:
To test treble detail and resolution in an IEM, you’ll want tracks that contain intricate high-frequency elements and subtle nuances.
Smoothness and Sibilance Control:
To test treble smoothness and sibilance control in an IEM, you’ll want tracks that contain vocals with sibilant sounds (like “s” and “sh” sounds) and high-frequency elements without being harsh or piercing.
Overall Treble Quality and Balance:
The track Pink Floyd - "Comfortably Numb" features a layered soundscape with guitars, synths, and vocals all sharing the treble space. Delci somehow managed to present a clear and detailed treble without any particular element being overpowering but it didnt excel which is understandable at the price point.
The track Mozart - "Piano Concerto No. 21 - III. Rondo (Alla Turca)" has a bright melody played on the piano. I chose this track to test the balance and smoothness in Delci. The overall presentation was smooth and enjoyable without excessive brightness or harshness.
Technicalities: 4/5
Final Verdict:
Well, with all that said, It's a green flag for me. Delci has proven that good IEMs can be affordable. By no means it's a perfect IEM but with its offering at the given price point I really think this should be your go to iem for longer listening sessions. Bassheads would really enjoy this iem.

Sound:
To describe the sound I would say that the Delci has an overall warm presentation with a fun and engaging high end. That's not it. Keep reading to find out more.
Bass : 5/5
Sub Bass Depth and Rumble
Testing sub-bass depth and rumble in an IEM requires tracks that feature deep bass frequencies and powerful sub-bass elements.
- In the track Massive Attack - "Teardrop" I felt the rumble was good enough. I was clearly able to hear the low sounds distinctively. It shows that Delci has a good bass extension.
- In another track by The Weeknd - "Starboy" it almost gave me a subwoofer effect.
Control and Tightness
To test bass control and tightness in an IEM, you’ll want tracks that feature well-defined basslines and controlled low-frequency elements.
- In the track Daft Punk - "One More Time" the bass wasn't very tight but it was not loose either, I'd say it was sufficient enough not to sound sluggish.
- I used another track, Stevie Wonder - "Superstition" where i felt the bass was just tight enough.
Mid Bass Punch and Slam
Testing mid-bass punch and slam in an IEM requires tracks that emphasize the lower frequencies with impact and depth.
- In the track Beastie Boys - "Sabotage" the bassline the punch is adequate.
- I also verified with another track from Muse - "Hysteria" and I felt the mid bass in the distorted bass guitar.
Mids: 3/5
Lower mids: Body and Warmth
To evaluate lower mids body and warmth in an IEM, you'll want tracks that feature rich vocals, acoustic instruments, and low-register instruments like guitars and cellos.
- The track Norah Jones - "Come Away With Me" felt smooth and warm with rich female vocals. However, the bassy instruments felt slightly recessed. Piano, Strings and cymbals were easier to notice.
- In another track Coldplay - "Yellow", here the male vocals felt fuller and warm as well.
Upper Mids - Clarity and Detail
To test upper mids clarity and detail in an IEM, you'll want tracks that feature prominent vocals, guitars, and other mid-range instruments with intricate textures and nuances.
- In Radiohead - "Pyramid Song" as the track advances, Delci starts losing clarity and it feels like a few instruments get muffled with the vocals, the separation is not quite evident.
- In another track Diana Krall - "S'Wonderful" the vocals are forward but the instruments come out cleaner. Delci performs well with Jazz tracks.
Midrange Balance and Timbre
Testing midrange balance and timbre in an IEM requires tracks that showcase a variety of instruments and vocal performances across the midrange spectrum.
- The track Pink Floyd - "Wish You Were Here" features a variety of instruments like guitars, piano, and vocals all occupy the midrange. Delci is quite Balanced and presents a cohesive soundscape where each instrument has its own distinct and natural timbre.
- The track Antonio Vivaldi - "The Four Seasons - Spring" relies heavily on violins and cellos, both prominent in the mids. Delci is able to showcase the natural timbres of these instruments.
Overall Midrange Performance:
- The track Adele - "Someone Like You" features vocals which spans a wide range of the midrange. Delci is able to present her voice with warmth without being harsh.
- The track Steely Dan - "Aja" features a meticulously crafted mix with instruments and vocals seamlessly integrated across the midrange. Delci is quite Balanced and resolving and it reveals the intricate details and textures within the song.
- Upper mids are at times harsh. I noticed it on some tracks. Instruments like trumpets and electric guitar felt slightly harsh when I used a DC04pro but on ru6 it was fine.
Treble: 4/5
Treble Extension - Air and Brightness
Testing treble extension and brightness in an IEM requires tracks that feature prominent high-frequency elements such as cymbals, hi-hats, and vocal sibilance.
- In the track Led Zeppelin - "When the Levee Breaks" the cymbal strikes are not so well isolated but they are by no means harsh or sibilant. I would say the treble extension is just average.
- In another track Steely Dan - "Do it Again" the high hats cymbals crispness is decent and is not harsh
Treble Detail and Resolution:
To test treble detail and resolution in an IEM, you’ll want tracks that contain intricate high-frequency elements and subtle nuances.
- In the track Antonio Vivaldi - "The Four Seasons - Summer " , Delci is able to resolve intricate details in the treble. The fast violin passages in this summer movement. The separation of notes isn't very clear and slightly sounds smeared together.
- In a bollywood track Surili Akhiyon Wale - Veer Delci picks up nuances and the bar chimes are very clean which plays at the back of the guitar picks layered with accordion.
Smoothness and Sibilance Control:
To test treble smoothness and sibilance control in an IEM, you’ll want tracks that contain vocals with sibilant sounds (like “s” and “sh” sounds) and high-frequency elements without being harsh or piercing.
- The track Nora Jones - "Don't Know Why", had peaks in the vocals but was not sibilant at all. Delci tamed the sibilance while maintaining clarity in the voice.
Overall Treble Quality and Balance:
The track Pink Floyd - "Comfortably Numb" features a layered soundscape with guitars, synths, and vocals all sharing the treble space. Delci somehow managed to present a clear and detailed treble without any particular element being overpowering but it didnt excel which is understandable at the price point.
The track Mozart - "Piano Concerto No. 21 - III. Rondo (Alla Turca)" has a bright melody played on the piano. I chose this track to test the balance and smoothness in Delci. The overall presentation was smooth and enjoyable without excessive brightness or harshness.
Technicalities: 4/5
- In most tracks I was able to hear the instruments crisp and clear. The Soundstage is spacious at average and has good width. The forward vocals also help with the stage height and I also got a hint of depth in some jazz tracks. One reference would be the track Miles Davis - "So What" where the instruments are spaced decently enough but not wide.
- Imaging is quite decent enough for the asking price. In tracks involving 1-3 instruments, I was able to tell where the sound is coming from and how far but it was mostly left, right, behind my ears and behind my head. Using the same track as above I was able to feel the distance of all instruments.
- Resolution is great, it picks up nuances and expressed it so well. The cymbal reverbs sound beautiful. Layering is also something I feel it does very well. in the track Snarky Puppy - Lingus (We Like It Here), I was able to hear a lot of details. Also as the track progresses it adds on layers of each instrument.
Final Verdict:
Well, with all that said, It's a green flag for me. Delci has proven that good IEMs can be affordable. By no means it's a perfect IEM but with its offering at the given price point I really think this should be your go to iem for longer listening sessions. Bassheads would really enjoy this iem.

Kefine Delci Review
"The Prodigy"
Kefine Delci Review
Intro
This review covers the latest iem from the brand-new audio brand Kefine which goes by the name of Kefine Delci. The Delci is a single dynamic driver earphone which boldy steps up to the plate against the vast market of $50 to $100 iems. Coming in at an MSRP of $79. However, the Delci went on sale to begin its life at $59 and hasn’t really budged since then. So, for this review I will simply look at the Delci as a $59 iem. Which is a fantastic price by the way! Being that Kefine is still in its infancy as far as an audio brand is concerned, I find it remarkable that they’ve crafted such a formidable entrant into the market. The Delci is only their second iem which comes only months after the Kefine Klanar (Pietro’s Klanar Review) which happens to be a planar magnetic earphone that received some very good praise. The Klanar was released in October of 2023 and the Delci in March of 2024. It appears that Kefine is about to go two for two.Kefine
Kefine Electronics Technology Co. Ltd. was founded in November of 2022. So yes, this company is about as fresh and new as a company can be. I can tell you all, after speaking with Collin Yang (one of the founders of Kefine) that this is a brand created from a group of friends who sought out to bring to market the highest possible sound value that they can muster. I cannot begin to tell you how refreshing it is to see a small brand such as Kefine defying the odds in a saturated market. There’s something special about a small brand. Even more special is that they are a group of friends, like minded individuals who understand the market, and the community. I feel this is a company that all of us can get behind. However, none of this would even matter if their products weren’t very good. I’ve always been a fan of small operations, mom & pop shops, etc. which are born out of joy, hope, and actual risk.Value
Kefine comes from the name of one of their founders “Ke” and the word “Refine” coupled together. They believe that “High quality is not equal to high price” and that squeezing every last cent out of the creation of their products is paramount. Kefine decided not to add any unnecessary features or accessories and the packaging is as simple as they can manage while still maintaining quality. Meaning, the money goes into the product itself. Folks, I found it was ridiculously nice to read THIS “about” section at kefineelec.com. This is what it’s all about friends! Real music enthusiasts who understand the consumer. They understand what we go through, constantly seeking the best value for our dollar. It isn’t easy to create real “value”. In this day and age especially. I think it goes without saying that I feel this is a brand to watch closely for every release they have going forward.Delci
I love a good name folks. It’s nice to see a brand actually name something with purposeful intent. We see it from time to time, but mostly we get “number names” with “pro”, “plus”, or “ultra” attached to the end. You can tell when a product is a labor of love. When there is true passion involved you would never name your product a “number name”. You’d think of the perfect name. I realize that I’m going kind of long on this and many of you could care less. But I care and I like seeing brands that care. I actually envision the hundreds of names floating around between this group of people, searching for the perfect name that embodies the character of their product. “Delci” actually means “Pleasure, delight”. I’d say that they just about nailed that one. It’s a fine name. With that all said, let’s get into this review. The Kefine Delci…Non-Affiliated Purchasing links:

Packaging / Accessories
Unboxing
Kefine states that they put less money into the unboxing experience so that they can better equip the actual earphones. Well, I’d say that they didn’t skimp all that much because the actual unboxing experience is pretty nice for a $59 iem. The box itself has a sleeve covering with a picture of the Delci on the cover, some stats on the back too. Slip the sleeve off and you’ll see a simple black box with Kefine imposed on the front. Open the box and you’ll see the Delci looking all dapper staring back at you. Next to the Delci is the carrying case. Inside the carrying case are the tips as well as the cable. I realize that I don’t really do much justice in explaining these unboxings, but I can assure you that the Delci’s is pretty good. That is always predicated on how good the actual accessories are. Altogether, not bad at all.
Eartips
Now, the eartips are actually of pretty decent quality. Kefine adds in seven pairs of tips in total. They provide four sets of dark gray silicone narrow bore tips which lift the mid-bass and slightly soften the upper mids. They also provide three sets of semi-wide bore dark gray silicone tips which elevate the lower treble and add a bit more of a distinct impact in the bass. To be completely honest, I didn’t get my best seal with any of them. I actually went with the large sized KBear 07 tips which helped the Delci fit like an absolute glove in my ears. Not to mention that with the 07’s I hear a slightly more impactful low-end while adding some vibrance up top to a degree. Seven pairs of tips at this price are nice. Couple that with the fact that the tips they do provide are actually decent. Not bad.
Carrying case
Providing a carrying case is another thing which kind of goes a hair above and beyond the usual call of duty at this price. Of course, it certainly isn’t unheard of, but I’d never expect a carrying case at $59. However, Kefine is trying to build their brand and they are thinking of the consumer here, so they did add in a case. It isn’t some ultra elegant case but it’s a nice addition. Especially for a first time iem owner or someone who uses cases a lot. I never use them but that’s me. At any rate, the carrying case is black and made of faux leather. It’s plenty large enough for the earphones, cable, extra tips and maybe a small dongle dac. This is a zipper case, and you’ll notice “Kefine” printed on the top. I appreciate the addition here and it shows that Kefine at least is trying to provide the best experience for us hobbyists.
Cable
Now, this is an area that surprised me. The cable provided is a very good wire that looks really fantastic on the Delci. Brown-on-black looks flat out dope with the gunmetal color of the Delci. I don’t know much about this cable other than it’s a 2-pin black & brown twisted cable with 164 strands of OFC copper which terminates in a 3.5 single ended jack. Folks, this is a very nice-looking cable. It has some beef to it. It isn’t some flimsy junk cable that you’ll need to swap out. The colors match perfectly in my opinion as the earphones and the cable look very nice paired together. However, I did swap cable for use with my balanced sources. I actually went with a brownish/silver 2-pin 4.4 balanced Youkamoo cable. However, for all 3.5 single ended listening (which was a lot) I was more than happy using the included cable and I think any of you would be as well. Certainly, one of the better cables offered at this price.
Build / Design / Internals / Fit
Build Quality
I was kind of blown away by the Delci. I don’t think I’ve ever had in my ears an all alloy (aluminum) iem that feels this ridiculously light. The Delci weighs just over 5 grams, and it feels like nothing in the ear. I am very pleased by this. Anyways, the Delci is made entirely of aluminum by way of CNC machining and built to last folks. This is a very durable earphone as it is solid as a rock. The Delci also has two small vent reliefs, one closer to the nozzle and one near the rear of the unit which add relief to both sides of the dual-cavity design. The nozzles are of medium length and so as long as I tip roll then I will have a wonderful fit every time. Friends, there is something to be said for a very light all alloy earphone and weighing just 5 grams is taking things to a whole new level. For $59 this type of build quality isn’t unheard of, but I do think it’s a selling point and should certainly be noted. No rough edges, clean lines, smooth transitions, with great structural integrity.Lightweight & Elegant Design
Experience comfort like never before with Delci’s lightweight and elegant design. CNC-machined from a single piece of aluminum alloy, Delci is both durable and stylish. At only 5.3g per side, Delci is one of the lightest metal earphones available, providing hours of comfortable listening.

Design
Now, the design of the Kefine Delci has gotten some push-back. Some folks have messaged me saying that it is pretty plain and not really up to their liking. I wholly disagree, but I am not them. I only say this because I have to be fair and speak what I know. Not everyone is going to be a fan. That out of the way, I think it’s great. I have been on a kick of late, really enjoying sets that are less “flashy”. I love an iem which has that minimalistic and bold type of design language because if it is done right then you’ll have a very fine looking iem, and the Delci is just that. I’d say the Delci has this grayish/brown gunmetal colorway from front to back and no other colors to choose from. However, when paired with the included cable, the Delci looks very nice, very sleek. There is a masculine feel to the Delci but also with a hint of elegant design as well. The more I look at them the more I am bewildered by what a hobbyist can get for only $60. At any rate, all brown except the faceplate which has a tasteful raised face with the Kefine logo imprinted on it. It’s a very nice look and I usually do not like logos or names on my faceplates. This is an earphone done right. Nice work Kefine!Durable & Stylish Housing
Delci’s sleek gunmetal finish is achieved through precise CNC machining, polishing, and anodizing on aviation-grade aluminum. The result is a durable housing that exudes elegance and sophistication, ensuring your earphones remain scratch-free and looking pristine.
Kefine Promotional
Internals
Kefine chose to use a 10 mm dynamic driver with a DLC (Diamond-Like Carbon) and PU diaphragm with N52 neodymium magnets within a dual cavity. They obviously used some good drivers and acoustic components within the housing of the Delci, and you will understand that the moment you put these in your ears and add a little volume. No distortion, nothing that would indicate that the driver is being stretched further than its ability. Of course, we have to keep things within reason. Still, I feel that Kefine certainly did put the money into the earphones and I’m telling you people, this isn’t an advertisement, I truly believe that Kefine is a player in this game folks!Fit
The fit for me is very comfortable. This set weighs only 5 grams! It is so very light! The Delci feels like nothing in the ear. I get a good seal right away with tips which work for me (KBear 07’s), and the rest is history. Just a very comfy iem. For me anyways. I have no idea how well they will fit you but I’m happy with that I can wear them for many hours without having any sort of issues. Isolation is also pretty good; about average I’d say. Not much different than most iems on the market.Drivability / Synergy
The Kefine Delci is rated at roughly a 28-ohm impedance and a sensitivity of 108 db’s. Basically, the Delci is pretty easy to drive. It won’t take any crazy amount of power to get this set to good volume. However, I do feel that the Delci does improve in incremental ways using a bit more juice. I also don’t feel that the Delci reacts in a bad way too many sources. I’m assuming that the nominal tuning is such that it won’t matter as much with a warmer or cooler source. The Delci is a warm/neutral sounding earphone and so it does play nice with just about every source that I own. Also, I did notice some scaling happening with more output. Of course, I also feel that (like any set) a lot of this improvement comes through simply using better sources. However, you will notice that many times an earphone will come across with slightly heightened macro-dynamics, better separation, tighter transients, more bass impact with more actual raw power… stuff like that.Mobile Listening
I spent time with many dongle dacs over the course of critical listening with the Delci. Out of them all I found the slightly closer to neutral sounding Aful SnowyNight as well as EPZ TP50 were my favorite. However, I do get better bass impact and weight with a device like the EPZ TP20 Pro. Listening over Bluetooth with the IFi Go Blu was a nice pairing too, especially on 4.4 balanced. However, of my Bluetooth devices I preferred the Qudelix 5k a bit more. That ES9219 dac chip has a clean response which seems to really dial in with the Delci attached. Usually, the Go Blu will outperform the 5k across the board but… synergy matters. I suppose if it was up to me and my perfect preference, I would go with a slightly closer to neutral source but that is not by any means a requirement. Mainly because the Delci really does sound great with anything I put it on.A bit more juice…
Of my more powerful mobile devices, I use the iBasso DX240 with Amp8 MK2 attached, the Shanling M6 Ultra, and the Fiio Q15. Each is very powerful for an iem. I never have to go past low gain, though I choose to use medium gain as there is a tightening up of the spectrum. Of these devices I love all three. The M6 Ultra is slightly warmer, velvet, with its AK4493SEQ dac chip. The Delci is so nice and warm resolving with the M6 Ultra that it’s hard to put it down. However, both the DX240 (ES9038Pro dac chip) and the Fiio Q15 (AK4191 + AK4499EX dac chips) run a tad closer to neutral and synergize only slightly closer to my preferences. I won’t 100% lean any one way though and I do believe that the Delci sounds really great no matter the source tonality… within reason.What do you need?
All you really need is a decently powered dongle dac. Shoot, you could probably get away with simply using a phone and a 3.5 jack. The Delci is not difficult to drive, and the dynamic nature is such that it sounds pretty impressive on most anything. So, a decent Dongle Dac would suffice. You can find some very capable and very nice dongle dacs for relatively cheap. As the market saturates, competition gets heated, prices naturally go down, and the consumer reaps the benefit.Sound Impressions
Note: before I dive into the sound, I just want to preface it all by stating that I did in fact burn the Delci in for roughly 75 hours, give or take. I did notice a slight change for the better. I don’t usually say this, but I have to report what I hear. The sound relaxed a bit, less intense in the sub-bass (still heavy though) slightly more balanced as a whole too. Also, I listened to many different sources during this time which helps me to get a feel for how the Delci behaves using these different source devices. I generally prefer Uapp (USB Audio Player Pro) as my music app which can be found on all of my digital audio players. Occasionally I’ll use Poweramp, and Hiby Player too. I use all flac or better files stored on my devices. All-rounder
I’m going to straight-up come out and say that the Delci is an all-rounder set which can replay darn near my entire library pretty well. A very good mix of musical and technical too. Folks, I wouldn’t be surprised to see some folks Rating this set the best you can buy under $100. I don’t know if I’d go that far because it is an impossible thing to quantify. But folks, this is a nice sounding iem. Of course, we all have preferences and so what’s good to me, may not be good to you. Also, there are some real and true KILLERS under $100 anymore. That said, I’ll tell you all without skipping a beat that the Kefine Delci is an absolute stud! It deserves to be in the top five, maybe top three almost across the board. It replays all genres pretty well and excellent for the cost and the tuning.What does it sound like?
The Kefine Delci comes across slightly V-shaped to even U-shaped to my ears with only mildly recessed low-mids. The sound is warmer than neutral but there are some moments of that neutrality coming through. There’s a very nice tonal balance across the mix with only a slight lean in favor of the sub-bass. No undue peaks, no huge, cavernous dips either. Just a bigger hill to the left and a smaller hill on the right. So, it is a warmer sounding set, but with a clean replay. It’s also an organic replay to my ears. The Delci provides a seemingly authentic timbre experience with a natural hue to everything I listen to. Also, the macro-dynamics are pretty vibrant and vivid for a warmer replay which adds some good energy to my music. Nothing boring here. It’s fun but it’s also composed, which is not usually the thing I’m saying at $59. Every area is represented well. From the bass, to the mids, and on through the treble, each 3rd of the mix has a stake in the dynamic balancing act that Kefine created. Not dry, analytical or thin either. This is a lush response which still creates space between instruments and still contours notes very well. Especially for the price (you’ll hear that a lot, just a fair warning). The stage is wide, Imaging is better than it should be, and separation of instruments is actually good!Condensed Sound Between the 20’s
The Delci has a very rotund, almost stentorian bass that doesn’t feel sluggish at all. Basically, I’m saying it’s able to bang and it does so with some precision while still being able to maneuver through more complicated bass lines with good micro-dynamic agility. The Delci’s low-end is pretty concise at decay and is nimble and ductile enough to move through the tonal shifts of even complicated bass tracks pretty well. I suppose some may want a hair less quantity and a slightly tighter rumble and slam (like a BA or Planar), but the Delci sounds very well done. It booms in a big way, sub-bass focused, haptic reverberant muscle. Still not for bassheads though. The midrange comes through only slightly recessed against the rest of the mix. Folks, the mids are very clean, rich too. But not in a warmly veiled and foggy way. This is a clear, relatively airy and open sounding midrange. There’s texture there, some definition to notes in the midrange as well. The treble is well extended, but it comes through with no annoying peaks. The treble is smoothened over and does well to uplift the sound as a whole. Technically the Delci is much better than it should be. I realize I’ve basically already said this.I have a set for you…
Folks, I just want you to get a good set that performs well across the board for the price. The Delci does so in its own way. There are so many tuning variations of what “good” sounds like. The Delci does V-shaped remarkably well, and it seems like the sound is effortless for these drivers. I want to give you options that won’t feel like a waste of money for you. I realize that some of you have already signed off on this set because it simply isn’t the sound you are looking for and I get that. However, if a nice sized bass, natural sound, a clean approach, good midrange and a non-offensive but also vibrant enough treble with a good technical foundation is what you are after… I have the set for you. Let’s check out each 3rd of the mix…
Bass Region
The low-end of the Kefine Delci can thump, and it can rumble deeply. Enough to satisfy those folks who enjoy some good ole’ guttural rumble. The low-end has some bravado, or at least some confident swagger and it does so in a physical way. What we have is a strong sub-bass presence and a nice glide downhill through the mid-bass on into the mids. The Delci does have some spill over into the midrange and I wouldn’t want it any other way. The sound is well structured, well textured, and there’s almost a certain deep pitched vibrance in the reverberant rumble. There’s a nice note edge as well. Not too smooth and with a nice amount of crispness too. Furthermore, the Delci also has good density and weight afforded to most notes in the low-end. Shoot, in the entire frequency. This is a well-done bass region which walks that fine line of mature and fun. Why can’t it be both?Sub-bass
The sub-bass definitely takes on the brunt of the low-end emphasis. This is a very physical, full-bodied and formidable bass that I can feel in a haptic sense. The Delci has a deep pitched grumble down low which extends better than expected. The Delci sub-bass has decent to good layering and textures to my music down low which does add some dimension and somewhat distinct layering of those sounds. I wouldn’t call the Delci pillowy or softly lined either. There’s contour to sub-bass notes (depending on the track) with good micro-abrasive edges to the sound. However, the nice thing about the Delci sub-bass is how deep it can rumble while still keeping the note edge. It’s a clean sub-bass for the price. Not quite basshead but great for fans of a good and elevated lowest of lows. Listening to “Mancey” by Andrew Bird, the bass guitar gets very low in pitch in this instrumental track and resounds in a very sonorous way. Most sets will carry the bass well but not all can do so with roundness to the note. With convexity. The Delci easily pulls this off while also sounding organic and ultimately pretty clean too. “Paradigm” by The Head and the Heart is another track that’s very deep with a raucous bassline. The Delci has no issues at all as it holds that low drone with nice energy and separates the lead’s voice in a well delineated manner. No real masking at all. The sub-bass (in my opinion) could be considered the cornerstone of the tuning.Mid-bass
The mid-bass is tastefully done. Kefine knew exactly what they were doing as the mid-bass isn’t as lifted and forward as the sub-bass, but it is still impactful and can add ever-so-slight amount of wholesome fullness to the midrange while also adding just enough boom to bass drops, kick drums etc. Listening to “Move Along” by the All-American Rejects is a track which begins with very heavy kick drums. With the Delci in my ears, it shows a slight lack of emphasis in comparison to the sub-bass. Just a tad less rambunctious and meaty then some iems with over emphasized mid-bass replays. However, the mid-bass is both fast and tight in its decay. Not as full-on robust in authority or as bulbous as most but I do find that it’s enough for most any genre. Slightly dry and less humid in its density but good for complicated bass passages in my music. I find the Delci’s mid-bass to have a nice leading edge at attack, but it isn’t as hard lined as some sets. Without question it sounds nice, but I did feel that is worth noting. It definitely leans mature, clean, detailed and still has enough punch to carry most any track.Downsides to the Bass Region
Without question the number one downside will be the elevated nature of the bass in general. I have many friends who only want the ultra-tight and snappy low-end that doesn’t even hint at getting in the way of the midrange. In the Delci’s case, I do hear a slight bleed over into the mids. But also, I think that is a very good thing and helps in a myriad of ways. Other than that, there aren’t many issues that I see. The bass is deep, fast for its size, clean and decently well defined. Definitely a huge selling point for Kefine.Midrange
I find the midrange to be quite nice folks. I really do. This was one area that I thought for sure I’d hear a typical V-shaped sound. I couldn’t have been further from the truth. Instead, the midrange is only the tiniest of hairs pushed back, good clarity, speed, and separation. Also, the midrange has good note density. Meaning, there’s actual body to the notes. The mids are pretty milky if you ask me. Certainly not dry, thin or analytical sounding. Also not fuzzy, cramped or veiled but… milky. I think the mids are great folks. No this isn’t some mid-centric iem which is made for vocals to shine. Having said that, for a slight-V to U-shaped tuning; the midrange is very present and highlighted, especially for vocals of both male and females. No, they aren’t out on a pedestal or pushed further forward, but the depth of the midrange, the spacing, the cadence and the natural timbre do help the Delci’s mids to hold their own very well.Lower-midrange
The low-mids have just enough body imposed upon its notes from the low-end. There is an essence of warmth, north of neutral, and replays good and defined notes. Males have very nice tonality and separation is such that it allows their voices to sound almost prominent in the mix. Not quite though. It’s very tastefully done. The track “Colorado” from Cody Jinks features his deeper voice with a nice crisp inflection when the Delci is in my ears. I love the realism to his voice with this set. He sounds almost lush, but with enough crispness to also sound accentuated. If that makes sense to you. His voice doesn’t melt into the surrounding melody. The slight bleed from the bass region is showing its value on this track. Again, tastefully done. I keep saying “defined” and I’m looking for other words but English only gives us so many. However, Cody’s voice is defined well, and the body is there, and his voice does stand out and is well separated from the strumming guitar. Another track is “Time Stand Still” by Foy Vance. Now, in this track, his voice does sound a hint pushed back, not as forward I’d say. Or better said, his voice is in the same plane as the melody surrounding him. Of course this is the way the track is recorded too.All in all, the low-mids are very nicely done for such a low cost. Instruments and voices come through with some added warmth, density and even some good depth for layering. I find I’m missing nothing with this set. Also, the low-mids are just clean enough to take this richer note weight and simultaneously have good separation and clarity.
Upper-Midrange
The higher portions of the midrange which usually, but not always, is where females reside. Most female singers are forward and even have hints of elated shimmer which sound perfect in a female voice. The pitch, tone & timbre all stay organic but in a slightly more vibrant way. Despite that, I also don’t hear anything shouty… ever. I feel the Delci takes me right to the cusp of shout and then pulls the reins back in. There’s a pleasantly gradual rise in the pinna gain and a seamless transition into the lower-treble. The upper-mids are nicely displayed against the higher peaking sub-bass and bass region. Never too strident, never shouty, never metallic. This is organic and natural in a wonderful way folks. Listening to Caitlyn Smith in the track “High”, the Delci has no issues capturing her elegant and feather soft build up to the chorus with a sweet tone to her voice, clean edges and nice emotion. However, it is the chorus that breaks apart most every iem on this track. In this song Caitlyn is in “ballad” mode belting her heart out while musical mayhem goes on around her. No doubt to emphasize her feelings. The Delci takes this track and compartmentalizes each individual sound very well for a single DD. Obviously, multi-driver sets have the capacity to do a bit better (doesn’t mean they will) but for a single dynamic driver earphone, the Delci is great for females.Upper mids cont…
The upper-mids on the Delci are so much different from some of the other sets which head up the top-five in most folks under $100 lists. Most of those sets have a more pronounced upper-midrange with a slightly less natural and more energetic sound. There’re obviously a few detractors from that but for the most part it’s copycat tuning. Not Kefine. I actually love what Kefine did here. This is not a Simgot upper midrange. They didn’t copy anyone. Kefine took their own route and managed to absolutely nail this region folks. Females have body, they are crisp when they need to sound crisp, resounding when they need to be resounding, and they do it all within this wonderful capped upper midrange canvas. Never sibilant, never peaky, never glaring and never metallic sounding. Just pleasant. I suppose some folks will want more energy and I expect that. However, I cannot help but congratulate Kefine on a job well done. Females and higher pitch males sound very nice.Instrumentation
Instruments are just the same. I feel that all instruments hit my ear with a natural sound to them. I hear nothing that is straight up wrong sounding. Not with the Delci. The only issues that I hear with instruments is with how the tonal & dynamic characteristics of the sound come across. Like in some percussion you won’t have that super lively snap to the sound as some sets. Snares sound great but they aren’t quite as strident and punctually biting as something like the Simgot EA500LM for instance. Not bad by any stretch but I want you to know what you are getting. Kick drums also could use just a hint more immediacy in the leading edge. Better said, they need that tacky edge to the big hollow boom. This doesn’t mean the Delci doesn’t have that, but it isn’t as noticeable. All strings sound nice, edgy enough, detailed enough to pick up the harmonics very nice, the finger slides etc. Okay, I’m not going through every note on every instrument as it is a foolish undertaking, wastes far too much digital ink (that’s a joke), and uses too many words for a reviewer trying to keep his ever-growing word count down. The point is, the Delci recreates most instruments in a very organic way, and it really is nice to hear at the price.Downsides to the Midrange
The biggest drawback of the midrange would be for those who would much rather have that ultra-snappy and transient swift type sound. The type of sound which is born and bred to be clinical and analytical. Despite that, the Delci does have good technical chops, it just isn’t tuned to be a proper “technical beast”. It isn’t planar or BA quick either. I would also flip that coin and say that people who enjoy a much warmer & darker sound with syrup thick notes which ooze emotion are likely going to want to keep looking. Besides those two types of hobbyists, I don’t think the Delci misses much. It’s musical, transients are actually pretty snappy for a single DD with just enough decay. The Delci has good clarity and resolution for what it is, and the sound does have an emotional element to it. Add to that, the midrange is fairly well detailed too. Honestly, I don’t have much to complain about.Treble
Looking at the treble region on the Kefine Delci, I would first point out that the sound is kept in check without any forced and unnatural vibrancy, or without oversaturating the upper portions of the mix in treble glare. Again, the Delci will take the listener right to the brink of intensity and then pull back the reins. There’s a soft cap on treble levels while still coming across with mild brilliance and sparkle. You won’t hear forced resolution brought on by boosting the treble through the upper treble. Many times, we will see these areas lifted too far in hopes to bring out micro-details and such. Just enough brightness to add some levity and luminance to the mix and this shows up at lesser or greater levels depending on the track and your source. Now, details are illuminated just fine in this region depending on the track of course. More on that later. Supplementarily, the treble also manages enough shimmer, air, and openness to create space, which adds some dimension to the upper portions of the spectrum. This isn’t some drab and boring treble either. I don’t want my words to come across that way. There is adequate and even better than adequate air and shine up top without offering any fatigue. This is as brilliant as a treble can get without coming across offensive. My opinion.Not a treble head’s dream, not bad…
For the most part, the treble has a smoother sound than it is crisp. However, this in no way means that the treble doesn’t have some bite to it when called upon. No this isn’t BA, Planar or EST etc. treble and DD’s do have a harder time portraying the contour and roundness to notes at times, but I find the Delci does pretty nice. At the very least I’d say that for the $59 that Kefine is asking for, the treble plays very well with the rest of the mix and really does fit the tuning perfectly in my opinion. Certainly not a treble head's dream though, as it isn’t so boosted that treble junkies will be drooling or anything. Also, the bass region does have the bragging rights of the frequency. So treble heads probably won’t be impressed. That said, the upper portions of the mix do have good clarity and transient swiftness while I also hear good separation of instruments, voices, and harmonics. Stuff like the secondary harmonics of a cymbal strike never sound tizzy to me, or splashy at all. Always under pretty good control and decay in a natural way.Extended… but not overcooked
Extension is another benefit of this tuning. I really like how Kefine kept the overall brilliance under wraps without losing control of the brightness while also giving the Delci a well extended sound up top. There is way more info past 8k then some folks probably know. I’m really not missing much of anything. Like I just stated, the extension isn’t the type which comes across metallic or splashy and never tizzy, which is a testament to Kefine’s tuning abilities. Is it perfect? C’mon, nothing is perfect and yes there are things I’d like to see. But also, this set is a budget iem folks! We can’t lose sight of that. There is only so much Kefine or any brand for that matter, can do at that price. So, with that thought in mind I really feel that this is a brand who knows how to be efficient with their time and resources to craft and create a set that replays my library like the Delci. The extension is nice, it’s actually good, and they didn’t have to overcook the treble to get there. They kept the treble in check, no peaks, no glare, no sibilance that is noteworthy. Brands like the “Simgot‘s of the world” really do boost these regions which ultimately will be a bit polarizing to a huge swath of hobbyists. Granted, I enjoy Simgot’s style, but I would say with assurance that more folks would enjoy the Delci and their approach.Downsides to the Treble Region
The first thing which comes to mind is that treble heads or fans of this area are not going to be hugely impressed. I wouldn’t think so anyways. I know a few treble heads who would certainly look at the Delci as boring and probably not as vivid as they’d like. Treble notes could use some more 3D style bite and contour as well. The Delci does have a smoother than crisp sound and so I could see some people wanting a bit better. Also, for fans of a darker treble, I also don’t feel that they will enjoy the Delci either. Honestly, the Delci sits right smack-dab in the middle of both extremes. I find the treble nice but not everyone will share my feelings.Technicalities
Soundstage
Okay, for a V-shaped iem, a single DD, a budget set, and for a bass heavy iem… the Delci has a much larger stage then I would’ve thought. Large as in… wide, tall, and reasonably deep. All dimensions are heard which does come across as slightly holographic. What I mean by that is the stage as a whole has a certain roundness of elements and layering which occurs. It isn’t some huge coliseum or even a large room, but the stage is very nice, and the overall sound quality is better for it. As always, not every track will come across this way. This is why I use the same 10 tracks to check for stage size. I will highlight one that I usually use in “Hook” by Blues Traveler. Right away the guitar persists past my ears with the drums beating in the background and the harmonica coming in just in front of the drums. It’s an easy song to pay attention to. After all, it’s the same damn chords played over and over again. Dimensionality, like front to back, width, and height comes through loud and clear. Once you’ve listened to a track such as this (along with any other track) then it’s easy to hear the ability of a set-in comparison to other sets. The Delci are pretty good friends. I’d say above average for a budget single DD. Which is pretty good.Separation / Imaging
For the most part separation is pretty good. Probably better than “pretty good” actually. Unless you are listening to a track with heavy and consistent bass play. The Delci bass will overtake and slightly mask the sound at times. No real good way to get around that. Maybe EQ, or tip rolling. Anyways, the separation of elements within an imaginary stage is better than they should be. The only other caveat would be complicated tracks. Obviously, single DD’s will usually have a slightly harder time creating a distinction between these elements (instruments/voices) in more congested songs. Though Kefine has done a good job crafting a set with a good dual cavity and good acoustic properties which does help in this regard. Imaging is actually very well done and easily parsed out in my opinion. The sound is pretty clean, good enough resolution, tighter than usual transients for a budget single DD, good space as well which does help to separate the sound field elements. I also feel this helps a lot with where each of those elements are within that sound field. I can hear the partitioned off instruments with good left to right imaging as well as decent enough layering and front to back depth. Not bad at all.Detail Retrieval
Details are very good in a “macro” sense and better than they should be in a “micro” sense. Beyond micro-details, I find the Delci performs well with micro-dynamics too. The quality of the sound is of a very high value for the price and the quality of the drivers I feel must come into play as well. Details do emerge pretty well. Let’s just say this; I don’t hear anything awfully congested or mashed together. Again, unless the track has a heavy bass presence or the track you are listening to is overly complicated and congested. Those are your caveats for detail retrieval. Any other situation and micro-details are brought to the surface with good clarity. Good for a budget single DD anyways. Honestly, for a fun, V-shaped iem with a richer note weight the Delci has performed very well in this regard. Musicality first iems aren’t usually very technical. Like I said earlier in the review. The Kefine Delci toes the line of musical and technical very well for what it is.Comparisons
Kiwi Ears X-Crinacle Singolo ($79)
The Kiwi Ears X-Crinacle Singolo (soon to be reviewed) is Kiwi Ears latest budget offerings and another pretty good one at that. The Singolo is actually a collaboration effort between the YouTube personality “Crinacle” and Kiwi Ears. Folks, I love Kiwi Ears. They have made some special sets over the course of the last couple years. The Singolo is a single DD with an 11mm LCP driver and the special KARS (Kiwi Acoustic Resonance System) technology. This is a set which comes in with an MSRP of $79, just like the Delci. However, like I’ve said, the Delci went on sale and since hasn’t gone back up to MSRP. At any rate, the Singolo is a highly acclaimed and hyped iem which has gotten quite a bit of notoriety over the last month or so. Let’s find out how they differ.
Differences
Looking at the build quality, the Singolo is made purely out of resin and is formed very nicely. However, the all-aluminum build of the Delci is a step up in my eyes. Both are very nice but there is a difference when both sets are in hand. As far as the design, I’d think more folks would gravitate to the Singolo. It has those Kiwi Ears gorgeous faceplates, cool logo, wavy glitter mixed with bold colors, a clear shell and a smooth feel, just like a few other Kiwi Ears sets. As for me, I like the Delci. I like the simple aesthetic. I like the minimalist but very confident look and appearance of it. Accessories go to the Delci. Much better cable, better accessories in general. Both fit nicely but the Singolo probably offers better comfort for most folks. These are minor differences though as I feel both sets are comfortable for me.Sound Differences
The Singolo has a closer to neutral sound as it’s big sub-bass presence really doesn’t warm the mix quite like the organic sound of the Delci. I find the timbre quality of the Delci is simply closer to realistic to my ears. It does take a couple more db’s to get the Delci to the same volume, but I’d also say that the Delci is rewarded a bit more with better sources and more output. The Singolo has that “Truthear Zero” type of bass-tuck tuning, where the mid-bass does a deep-dive roll-off into a scooped lower midrange to create a sort of sub-woofer effect. The Delci has the more typical tuning but with better perceived cohesion.Between the 20’s
Listening to the Singolo I hear a more guttural sub-bass by the tiniest of margins, but the Delci has the cleaner bass to my ears. More exact in its leading edge, maybe a bit more precise too. Singolo sounds a hint softer, more detached (which isn’t necessarily a bad thing). The mid-bass slam of the Delci is bigger, a hair more authoritative and the transient response is tighter and better for complicated tracks, better defined. The midrange of the Singolo is thinner sounding, less rich but better technically. Details emerge a bit easier, and separation is more evident. Take nothing away from the Delci because its musical sound is a huge benefit against the Singolo’s drier midrange. I just find that Delci’s vocals, instrument timbre, and overall appeal will likely suit more folks. The treble region of the Singolo rolls-off sooner. It’s less brilliant, less air, thinner in note body and less engaging.Technicalities
Details go to the Singolo. I only say this because the bass doesn’t really congest anything on this set. Also, the midrange is very clean, neutral and transient attack through release is relatively quick. Instrument separation is good in both sets, but the Singolo probably makes it easier to discern. However, the imaging is a bit better on the Delci with better layering of sounds in my opinion. Of course, these are not huge differences, but they are in fact differences, nonetheless. The soundstage is wider, deeper and equally as tall on the Delci. I feel this is a huge thing because the more holographic type of sound does add a lot to my music.Further thoughts on this comparison
This comparison will come down to preferences. You really have to enjoy that deep sub-bass and rolled off mid-bass along with thinner, but also cleaner midrange notes. It takes a minute of brain burn to really grow to enjoy. I actually do like it quite a lot. However, between the two I feel this is a no brainer for me. I like the Delci, it is truly a top-class competitor in the price range that wins over for its musical sound, it’s fun sound, but also, it’s better than average technical chops. Both are very nice, and I’d understand anyone arguing against my thoughts but for me… Delci.Simgot EA500LM ($89)
This next comparison features one of thee best iems that money can buy under the price of $100. My opinion of course. That set is named the Simgot EA500LM (EA500LM Review). The LM is a true “top class” iem with a huge following. Simgot has truly been on a tear through audio, like nothing I’ve ever seen. They’ve single handedly changed the game and forced other brands to step up their game. As far as the LM, it’s the successor to the wildly popular Simgot EA500 (EA500 Review). The LM is another single DD which houses a 2nd gen. 10mm lithium-magnesium dynamic driver inside of a beautiful chassis. I have to admit, this is a tough challenge for Delci. However, I could also state that these are two entirely different sounding iems.
Differences
Both of these iems are built entirely of metals, with the LM being stainless steel and the Delci completely made of aluminum. Both are built wonderfully but the Delci weighs only 5 grams. This is a huge difference from the LM which is as heavy as a brick. Both are comfy enough but no doubt the Delci takes the prize. One big difference with these two is that the LM actually comes equipped with three sets of tuning nozzles to tailor the sound to your preferences. Now, the look is an entirely different thing. The LM is truly gorgeous with its gunmetal color while the Delci also has its own bold charm to it. Both sets have a good unboxing experience. Honestly, as far as aesthetic is concerned, the LM is simply a beauty folks. I do enjoy both designs, however.Sound Impressions
Both sets come across very cleanly across the mix. The LM has an almost neutral sound, whereas the Delci has a warmer and richer sound. Without question the LM is brighter and gets very close to shoutiness much easier than the Delci. The LM has a bit rawer energy in its sound but both sets have plenty of exuberance. Between the two, the Delci has the more organic sound which is closer to realistic to my ears. I find the Delci to have a bit more of a traditionally musical sound as well, though that interpretation may be different for everyone. Unless you can tell me what “musical” sounds like. Lol. Having said all of that, the LM also has some fantastic timbre of its own and may be one of its strong suits. Both sets really do have a very refined and resolute sound respective to each sound signature.Between the 20’s
The Delci has a deeper sub-bass that comes across more authoritative and bolder. It’s just bigger across the board with less treble impacting the perceived bass quantity like the LM. The balance of the spectrum leans to the left for the Delci which naturally brings on more warmth to the sound. Listening to the LM you’ll hear more brightness which cancels some of the lower bass tones at times and in certain tracks. Both bass replays are very well perceived, but the LM is simply less guttural. I’d also say that the LM has a slightly softer leading edge to its bass notes. The midrange of the LM is more forward, possibly shoutier in some tracks, while the Delci is more reserved, less energetic, more emotionally charged and also less fatiguing too. Both sets do vocals very well for the price and both offer their own solid take on vocals. The LM is more forward, a hint thinner, more vibrant, slightly more energetic, tighter transients, more crispness & snap to percussion and better vocal clarity. The Delci comes across closer to natural, slightly smoother, lusher, with a more mellifluous type of midrange, debatably more musical. Again, both are very nice for what they are and the style of sound signature that they each represent. The LM has a brighter treble, more detailed, more crunch and bite, while the Delci has better extension into the upper treble without any undue peaks.Technicalities
Technically speaking the LM is probably the more detailed iem between the two but the difference is negligible. Honestly, I feel both sets are very good in this regard. However, the LM is simply more illuminated and not as rich in sound which does help to bring the subtleties to the surface easier. Again, negligible. I feel the Delci does just fine as it’s just as clean sounding but simply more robust in note weight and less luminance up top. The LM and the Delci offer good separation of elements though the LM makes it easier to distinguish for me. Imaging is nice in both sets, though the Delci does provide just a hair better layering of sounds. Which brings us to the soundstage. After a lot of listening to these two I found the Delci to have a wider and deeper stage. I’m not saying the LM is bad here either. Both have a nice rendition of the sound field, but the Delci is a bit vaster in size. However, these are “in-ears” and so the difference between the two is slight. At the end of the day, both iems are nice technically. Both sets are resolute enough and clean enough per their respective tuning. Let’s put it this way…neither is a slouch.Further thoughts on this comparison
I don’t know why, but these comparisons always turn into battles. I really try not to do this. Rarely do I succeed. However, I cannot say which set is better between the Delci and the EA500LM. For me anyways, because I do love them both. Both iems are truly fantastic for the price point. Also, both iems offer a different take on my music. Once again, this is a comparison which comes down to the consumers preferences. Hence, a “preference battle”. The differences are stark enough that neither really “wins”. Your preference will decide the “winner”. Do you like warmer, richer, less offensive, bassier and more musically inclined sound of the Delci? Or do you prefer a more energetic, dynamic sound with a slightly more detailed replay of the EA500LM? Both sets have an awesome timbre. I’d say the Delci is a bit more earthy and organic and the LM is more bright/natural or “off-natural” (if that’s a thing). I feel that both sets complement each other very well and I couldn’t say which is actually “better”, or which is a better value. I would certainly say that if you feel the Delci fits your listening preferences better than at $59 it is an absolute steal and would likely be the better value.Is it worth the asking price?
The $59 dollar question (at least while it’s on sale). Is the Kefine Delci worth the price that Kefine is asking for? To answer this question the best way you have to look at the landscape of iems within its price point. I can tell you straight up that if you get the sale price of $59 then the Delci is questionably the best iem you can buy. That’s if you enjoy this type of signature. There is a sea of good iems around that price, though many of those sets are tuned slightly differently, different driver configurations etc. No doubt there are some Ballers! Some awesome sets that easily could be sold for more than their price. However, the Delci is truly a champion of this price point in my opinion. At $59 this is the easiest no-brainer I’ve suggested yet.Different story at $79?
Now, if you are buying the Delci at the original MSRP of $79 then this is a different discussion. I still feel it’s worth the money but also you have better iems surrounding the Delci. The Artti R1, Artti T10, Kiwi Ears Melody, BQEYZ Topaz, Fiio JH5, Fiio JD7, Truthear Hexa, Simgot EA500, Simgot EA500LM, Simgot EM6L, BGVP P05, Muse Hifi East 6, EPZ Q5, EPZ X-Tipsy Star One, Letshuoer DZ4, TangZu Fudu, Moondrop Aria 2, Tripowin Olina, Tripowin OlinaSE, Dunu Kima, Dunu Kima Classic, and I’ll stop there. Please trust me that there are many more I could list. The point is, you simply have more options, and each option has its own realistic stake at one of the best under $100. So, at the price of $79 it’s a little bit more nuanced of an answer to the question of “worth”. However, with all that said, I still feel that the Kefine Delci is a no brainer. It really is that nice of a set.The Why…
Because the Delci is built like a champ. The all-aluminum design is one you don’t see every day, and due to it being aluminum, the Delci is ridiculously light. I don’t think you know how nice an ultra-light earphone is until you’ve used them for a while. Also, the aesthetic is one that is easy to enjoy with some of the better accessories within that loaded price segment. However, the sound is always the real reason why anything is worth its weight in audio…of course. Anyways, the Delci has a very engaging sound that teeters on being technically adept and musically inclined. Kefine did a nice job crafting a fun sound that doesn’t miss out on the finer things in my music. A nicely deep and authoritative low-end with a good transient swift slam. It’s not a bass which overtakes any other area of the mix in a detrimental way. The midrange is milky and creamy. Yet also resolute, which is a fine mixture of descriptors for an earphone. The Delci has a signature which doesn’t offer fatigue with a nicely rendered treble that has good extension too. In fact, the extension both ways help to give the Delci a nicely wide stage and good depth for a 3D type sound at times. Also, I love that Kefine is a small company made of actual enthusiasts within the hobby, I can get behind that. This is a very good set folks. I don’t even have to think twice about it, for me the Delci is worth every penny.Ratings (0-10)
Note: all ratings are based upon my subjective judgment. These ratings are garnered against either similarly priced sets or with similar driver implementations or styles with the unique parameters of my choosing. In the case of the Kefine Delci ratings below, that would be $50-$100 iems of any driver configuration. Please remember that “ratings” don’t tell the whole story. This leaves out nuance and a number of other qualities which make an iem what it is. A “5-6” is roughly average and please take into consideration the “lot” of iems these ratings are gathered against. $50-$100 US is a huge sized scope of iems, and so seeing a 9 should probably be pretty special. My ratings are never the same and each set of ratings tells a different story. Each time you read one of my ratings will be unique to that review. Basically, I create a Rating that makes sense to me.Aesthetic
–Build Quality: 9.5 Built very well, all aluminum.–Look: 9.1 Simple, bold, masculine.
–Accessories: 9.0 Pretty nice!
–Overall: 9.2
Sound Rating
–Timbre: 9.7 Top of class timbre (my opinion).–Bass: 9.3 Hello quality… meet quantity .
–Midrange: 9.1 Warm, rich, musical.
–Treble: 8.5 Non-Offensive with nice extension.
–Technicalities: 8.6 Technically better than it should be.
–Musicality: 9.5 Musicality is very nice.
–Overall: 9.1
Ratings Summary:
For a set being judged against any and every iem between the prices of $50 and $100, getting an overall sound score of a “9.1” is huge. That’s definitely up there in my book. However, ratings are a terrible way to determine worth. I’ve said it in almost every review that… I don’t like them. They tell you nothing in a sophisticated manner, and they can be taken for truth very easily. The actual truth is, ratings can only tell you individual attributes and how they rank in one reviewer’s mind, per each category. It’s almost a problem. There is so much more that goes into deciding the real value of something. There’s nuance to this game folks! Just as we are different as people, so are the devices which we review and listen with. It’s damn near impossible to label anything “the best” in anything. Too much subtlety, complexity, and variegated nuance. Rating values are simple, nothing nuanced. That said, I feel a “9.1” is probably about correct if I average out the scores. But as a whole if I were to rate the entire package that is the “Kefine Delci” … I’d give it a “9.5” without batting an eye. This is how ratings can be pretty deceptive. A set can look better or worse in individual rating points, but it may come together a certain way too. It’s not about the sum of the parts, but instead it’s about how it all comes together as a whole.Explain Yourself!
One thing which will always be divisive is “bass”. For whatever reason it is one of those areas which takes on the most scrutiny from the peanut gallery. I get more DMs about bass ratings than anything else. Do you rate on its boom boom capabilities? Or do you rate the bass region on its refined quality? In the case of the Delci, it’s a little bit of both. A “9.3” is fairly high in this price segment but I stand by it. Not many sets have a good quality with an elevated bass in this price point. There’s a couple but it’s rare. Also, treble heads will think I’ve lost my mind. How in the world can a relaxed treble score an “8.5”?! I would answer that it’s not about the quantity of brilliance and forced resolution all the time. Sometimes even a less brilliant treble which actually fits cohesively with the overall tuning can actually sound… better. Still, in this relaxed state, the Delci manages good details, has some bite, and has better extension than you may think. No, it’s not an ultra-defined EST type treble. But also, name a set under $100 that does have that type of treble. Yes, there are more boosted treble replays, I know this because I listened to them ad-nauseum over this Rating period. And yes, there are flat-out better treble replays. Hence why it’s only an “8.5”. The rest of the ratings I feel confident in.Conclusion
To conclude my full written review of the Kefine Delci, I want to give a warm thanks to the good people of Kefine, in particular to Collin Yang for sending the Delci to me. This is a smaller company, a lesser-known brand, and a brand which isn’t trying to add flash and fluff or boast in an over-the-top manner while advertising their products. Their ascension has been organic. This is a brand formed by friends and like-minded individuals with a passion to create something that they would love and be proud of. I cannot tell you how important these brands are for the hobby. These are the enthusiasts who keep this hobby afloat, who challenge the status quo, and who keep the bigger brands honest. So, for a small brand who is trying to create a successful venture into audio and who has just begun… I thank you wholeheartedly Kefine! You have most certainly made a good product and I do hope folks take the chance on the Delci.Thank you!
I also thank any of you who chose to click on the link and actually read this review. Similar to Kefine, we are a small website of reviewers who are trying to scratch out our spot in the hobby. So, it’s of great importance that any of you have clicked the link to our site. You are the deciding factor for whether we succeed or we fail and by all accounts… we’re doing pretty darn well. So, thank you. Beyond that, please check out other thoughts of the Kefine Delci. Not every reviewer sees things the way that I do. It’s that simple. We are very different, each and every last one of us. None two are alike. It would behoove you to look at other thoughts because we want you to make the right choice for you. After all, this entire journey is all about music folks. With that, I think I’m done with this review. Please take good care, stay as safe as possible and always… God Bless!

Review Of The Kefine Delci
Introduction
Kefine, a newly established company, debuted its first product, the Klanar, which was well received by many audiophiles, including myself. In my opinion, it was an upgraded version of the original 7Hz Timeless or LetShuoer S12 with better details and clarity while maintaining safe tonality. The firm specializes in electro-acoustic equipment, notably in-ear monitors. They just introduced a budget set called as the Kefine Delci, which I have had the opportunity to evaluate; however, before I go any further, I would want to clarify a few issues.
Disclaimer
*Since this unit tour was organised by the lovely people at Kefine, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “Delci.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the Delci based on their performance, even though I will explain how it feels and seems physically and aesthetically.
Specification
Delci features a single dynamic driver with a 10mm DLC+PU diaphragm. The shells appear to be composed of light metal, yet they look and feel well manufactured. In terms of comfort and fit, its lightweight and design made it quite easy to listen to even for long periods of time, and the fit was excellent. The cable offered is comprised of 164 copper wires designed to compliment the DLC diaphragm and terminates in a 3.5mm straight connector with two pins on the other end. The other included equipment are six pairs of eartips and a carrying bag. Technical characteristics include an impedance of 28 Ohms and a sensitivity of 108dB. The frequency response ranges from 20Hz to 20kHz.

Sound
When it comes to sound quality, this single dd IEM blew me away, and I feel they are the most well-tuned “balanced” sounding IEM under $100. I mean, I don't see anything wrong with it and I can't put them down. As previously stated, the response leans toward a tonally rich, revealing, and balanced sound profile. To believe that in this highly saturated category, an IEM that does not need to excel in sounding very precise or very target-specific, I am quite pleased with Kefine for delivering essentially an IEM that everyone will like. I mean lately, I also got the chance to evaluate the rose technics Quietsea which also follows a balanced sound with warmth in the bottom to mid region while sounding a bit spicy in the high area however the quality of the tuning Kefine produces makes the sound interesting and engaging.Alright, let's go further into sound to learn more.
Treble
So, I don't think there's a problem with the treble, and as I previously stated, this isn't a particularly target-specific sound like the CCA Rhapsody, QKZ Khan, or Truthear Zero, but rather a really nice and smooth adjusted treble. The treble holds the excitement at bay and attempts to make the details seem less exhausting and more revealing. A fantastic example is the upper treble; while listening to tracks like AURORA's Black Water Lilies or RADWIMPS' The great Escape, the higher treble helps show the small details yet does not sound excessively dazzling and glittery.The voice and instruments have a relatively broad and airy expression, yet they seem unified and relaxing to listen to. The lower treble tends to bring the energy out of the vocals where the instruments complement them. The vocals have a solid response, but the dynamic quality is surprising. This could be due to the fact that the instruments do not come across as sharp and detailed sounding, which allows the vocals to breathe and move around freely. As a result, the overall presentation of the treble range is mellow, calming, and expansive.
Mid Range
When it comes to the midrange, I believe there are two approaches I may take. The first is that some people may find it quiet, while others may find it tonally rich and true. From my viewpoint, both are correct; the reason being that the bass elevation and a peak in the upper treble at 11-12k make it sound not bizarre but distinct; I believe I can relate to the TangZu Fudu Verse in terms of how the Delci is tuned in the midrange. Don't get me wrong; I'm not suggesting they are deep and drowning-sounding vocals, but rather quite natural and relaxing. The upper mid-range places a strong focus on how voices and instruments should complement each other. In fact, I feel the upper midrange and lower treble have the same intensity and cohesive character, making the sound smooth and genuine. Returning to the point, I find mid range to be both somewhat subdued and tonally accurate because most IEMs in this price range bring vocals forward and splashing instruments, while IEMs that don't tend to sound very mellow as if the vocals are drowned, not that I compare them to the Delci. Delci gives harmony and tone richness to the voice and instruments, which I believe combine well. Regarding people's preferences, this may not meet your need for open-sounding female vocals and crispness. The lower midrange is adjusted to keep note weight and density under control, resulting in a tonally pleasant and rich response. The lower midrange has a thick and hefty response, yet it allows vocalists and instruments to be heard. As a result, the midrange presentation sounds natural, tonally correct, and rich.
Bass
When it comes to the bass, I have no idea why dynamic driver bass sounds so good. I love how fluid and adaptable this bass response is. Looking at the Delci's FR response, one could easily conclude that the bass emphasis makes it a bass-heavy IEM—in fact, that's exactly what I thought. Let me clarify that it sounds warm instead of bass-heavy. Although the mid-bass presence is also very noticeable, the bass emphasis is over the sub-bass region. The answer could be described as a prominent or influential bass presence that isn't overtly focused on pounding bass, but when it comes to bass-heavy tracks, it definitely reveals a very satisfying thumping and rumbling. While the slams and thumps in the mid bass region are controlled, the sub bass texture and quality make it easy to come through, giving it a deep, rumbly sound. Warmth that flows into the lower mid range is rather welcomed by the mind bass, but masking is not possible. To put it another way, the way the warmth is controlled and allowed to spread makes it sound like a calming and fulfilling reaction. In addition, the tonal accuracy of the kick drum, toms, and four-string bass guitar all exhibit a very organic response that is not cold or precise, but rather produces a warm and pleasant sound that is not sharp or edgy.
Technical Performance
I'm not sure if one should anticipate specifics and clarity from this duo, given the reaction is more tonally oriented. But I think the layers and staging are wonderfully done. Of course, for the price, they sound quite adequate in terms of technical capability, but for the amount of money spent, clarity is also expected. So let's get more precise for a better understanding.
Soundstage, Sound Imaging & Separation
The stage is well-established, with a wide spread that makes it sound spacious and allows for good pointing of the vocals and instruments, but they don't sound very precise and sharp, so imaging is not very clear and edgy, but clean enough to convey an understanding that the space between notes is recognisable, and the distinctiveness allows for a better presentation that sounds satisfying.
Speed & Resolution
As I previously stated, I feel that most micro details are not adequately revealed, while big elements are readily apparent. The assault and decay of the notes are not fast-paced, but rather natural, which helps to keep the mix from becoming chaotic.
Sound Impressions
Sources
Sony WM1A - while listening to Delci paired with WM1A, I instantly felt the stage becoming wider and spacious while the whole response sounded more warm and big. The response in the bass region or treble felt more extensive and large. But again the mid range felt richer and maybe more than it should. But all in all I find the pair sounding very emotional while listening to slow pacing tracks or concerts.
Tempotec V6 - While listening to Delci paired with V6, I noticed that the response was more forward and revealing generally, with the exception of the bass, which was less accentuated since the vocals, or upper midrange in particular, gave more revelation to the mix. The treble sounded similar to the asme, but with a more powerful response. This combo may be perceived as more distinct and defined, making it an excellent choice for those seeking clarity in their blend.
Simgot DEW4X - While listening to Delci coupled with DEW4X, the clarity and forwardness felt greater than any of my other sources, but DEW4X also maintained a coherent and tonal agreeable response. The clarity is attributable to the fact that the stage is narrower and more intimate, yet the whole reaction remains clearly defined and separated. The notes sound polished, making the overall response more fascinating. The combo makes perfect sense to listen to.

Conclusion
Finally, the Delci impresses me with its overall tuning for its melodic and pleasing presentation, which has not been surpassed by any other IEM. Whether it meets your taste in terms of technicality will depend on your testing, but from what I've heard, a well-balanced sound with a fantastic warmth and exquisite bass response makes it a really fulfilling and delightful experience, and for the price, I believe it's worth it. So these have my entire approval, unless you want to go with the same old tuning preferences you think would bring justice.

Personally I found the response warmish, I really can't comment on whether it follows a Harman target or any other specific target yet I am pretty sure it isn't a U-shape tuning.

KEFINE Delci :: 1DD IEM :: $59 (At the time of writing this review)
A somewhat unfamiliar brand, KEFINE debuted in last October with its first product - the Klanar, which used 14.5mm flat-backed drivers.
For a new brand's first product, it has attracted the attention of many people thanks to its surprisingly good quality, and if you look at some reviews, there is a mention that it is a sister brand of SIVGA / Sendy Audio, which has already made a name for itself as a high-performance headphone manufacturer.
hmm, now I get it.
KEFINE's second product, the Delci, is an IEM with high-performance 10mm dynamic driver made of DLCDiamond-Like-Carbon + PU composite, featuring a CNC-machined aviation aluminium unit for a lightweight, comfortable fit and an affordable price point.

Huge thanks to HiFiGo for providing a sample unit for this review.
However, this review fully reflects the my honest opinion without anyone else's interference.
Btw, are you more familiar with Korean?
So am I, and If that's the case, I think you'd be better off reading my review written in Korean here.
This entire review was translated from Korean article using DeepL Translator with some refinement by myself.

This is the package of KEFINE Delci.
Once you open the package and remove the manual, you'll see the unit and a leather case.
There's also a protective film over the KEFINE logo at the unit.
Here are list of the full components
- KEFINE Delci unit
- 0.78 2PIN to 3.5mm copper cable
- 4 pairs of narrow-bore eartips (S, M, M, L - M size preinstalled)
- 3 pairs of wide-bore eartips (S, M, L)
- Leather Hard case
If you look closely at the eartips, you'll see that there are differences in the size of the holes, as well as the overall shape of the eartip and the length of the core.
Eartips with wider holes have a more flattened shape and a shorter core, which naturally encourages the user to wear the earphones relatively shallow, resulting in a different overall sound characteristic.
We'll discuss this in more detail later.
This bundled cable is said to be the best match for Delci's Diamond-Like-Carbon (DLC) diaphragm.
It's a 54×2 + 28×2 copper cable, and thanks to the flexible yet lightweight characteristic of material, it was very comfortable to wear.
Combined with tight-fitting connectors and a great finish, and it was hard to find any flaws with it.
The leather hard case is very spacious inside, making it very easy to store the earphones.
There's also a mesh pocket on the top of the lid, perfect for storing ear tips or silica gel.
The KEFINE Delci has a precision CNC-machined aviation-grade aluminium unit design.
Based on an aluminium alloy, it was anodised to create a distinctive gun metal color, making it durable and scratch resistant.
Compared to other products, it has slim, light-weight, compact unit design. This makes them very comfortable to wear, and they don't protrude out of my ears at all.
A rather thick nozzle, about 6.1 mm thick, has a unique patterned mesh at the end, and a fairly dense damper is attached to it.
The faceplate design is a little underwhelming.
With the KEFINE lettering imprinted on it. It almost feels like a recycled Klarnar unit, and I honestly think it would have been better to have a circular logo instead of just engraving text on it.
But the more I look at it, the more I realise that it's actually not that bad.
'KEFINE Delci' uses a single 10mm dynamic driver.
This high-performance driver features a Diamond-Like-Carbon (DLC) + PU-based composite diaphragm with a Japanese Daikoku CCA voice coil.
A Dual-Cavity construction with it allows precise airflow to create a distinctive bass texture.
Measured with IEC 60318-4 (711) while maintaining 94dB@500hz.
The sample used for the measurement does not represent the characteristics of the entire product.
Following Measurements are available at silicagel775.github.io
Unusual for a single DD IEM, KEFINE Delci has a very impressive bass that stretches out linearly, as if was drawn with a ruler.
The sound is heavily weighted in the sub-bass, offering a deep rumble balanced between tightness and fullness, with just the right amount of punch.
Depending on the song, there's a little chance that the vocals can sound like they've taken a half-step back, but I got the impression that they have a crisp and clear midrange overall. They don't particularly stand out, but they don't diminish their presence either.
Instead, there's a good amount of treble, so despite having a fair amount of bass, it doesn't feel like it's muffled.
Overall, the KEFINE Delci has a rich resonance and a slightly crisp treble, with more of a U-shape than a V-shape sound.
I mentioned that there are two types of eartips available, each with different characteristics.
And from my measurements, there doesn't seem to be much difference except for a change in the treble characteristics - the treble seems to be slightly better with the narrow bore eartip.
However, in my listening experience, I got the impression that the bass rolled off a little bit with the wider bore eartips, shifting the centre of gravity away from the sub-bass and towards the treble.
The product description states that the 'bowl shaped eartips have a UV finish and wide bore for a more transparent sound', which kinda makes sense to me.
I'm not sure what's a 'UV finish', but I suspect it's similar to UV treatment that some gaming mouse manufacturers use to give a nice matte finish.
Normally, when measuring earphones, the insertion depth is adjusted to ensure that the resonance peak is matched at 8kHz so that it can be compared to other measurements.
However, KEFINE Delci had to be inserted considerably deeper than usual to achieve 8kHz.
Therefore, I think the purple graph is a little closer to the actual hearing characteristics than the blue graph shown earlier, and if you find the treble to be irritating, I would recommend reducing the size of eartip and try a deeper insertion.
It may not look like it, but the nozzle length is quite long, so the Delci's insertion depth is on the deeper side than normal.
So far, we've taken look at the KEFINE Delci 1DD Wired Earphones.
Delci is a pair of high-performance dynamic driver IEM that deliver punchy bass and sparkling highs, but there's a lot more to them than just the sound. A comfortable fit, flawless build quality, and decent accessories beyond the price point.
The only downside for me is the slightly bland unit design, but otherwise, they're a great value for money and a very well-built product.
I conclude this review with the thought that KEFINE, who has created another well-made 1DD IEM, is a brand worth keeping an eye on in the future.

Mids steps back just enough to add more space to the already big soundstage it lush and natural sounding, warm while maintaining clarity.
Treble is bright sparkly enhancing micro macro detail retrival and instrument separation adding to a more holographic sound experience.
Delci checks all the boxes i want in an iem, it has the crisp clarity and technicalities of simgot ea500 and the sub bass slam and mid bass smoothness of Hidizs mp145.
This is my new favorite sub 100usd iem Kefine Delci! it will immerse you with your favorite tracks with its powerfull smooth bass and indulge your craving for clarity and details with its well extended sparkly treble and the organic natural sounding mids that you get only from a well tuned dynamic driver. Subtle and elegant looking design, compact lightweight ergonomics fits and seals well in my ears.
In conclusion, the Kefine Delci IEM stands out as a compact powerhouse, offering exceptional sound quality and technicalities, comfort, and versatility in a sleek and portable light weight package, Delci delivers a performance that punches above its weight.

Big thank you to Kefine for shipping the Delci into for review. This is their 2nd iem in the line up after the Klanar. Kefine is a little word play on Refine. The owner of Kefine also wants to bring the best value for your money. Let's see if they succeeded in his mission.
Specs
Driver: DLC+PU DIAPHRAGM DYNAMIC DRIVER
Driver Size: 10 mm
Sensitivity: 108 dB +/- 3 dB
Impedance: 28Ω +/- 15%
Let's start with the package you get. The box is self in nice and pretty no trulls. The tips were a little con for me since they were tin of a material to make a proper seal for me whatever size I took to. I took my trusty Divinus tips on to them. The cable is pretty nice and on par with other brands and better than some others. Just wished it had a 4.4mm option but no biggy. Cables enough I landed on a Xinhs cable for the review. I always try to make what's inside the box work for a review since some people don’t have the luxury of having and owning a lot of cable source and tips. Ofc i can’t forget the carry case with a nice little accent on the zipper with their name.
The shell is really elegant and low profile. To flashy bling bling. Just straight up classy design. The nice touch I found is the flat spot they made to make sure the 0.78mm connector sits flush with the iem. it can happen in some iem’s that isn’t the case and that might lead to drop outs or bad connections down the line. They are CNC machined and they come in around +-5.3g which is still pretty light. So they don’t feel like throwaway candy when the next best thing comes out.
Sources used in this case Fiio Q11, KA17, M11Plus ESS, Shagling M3X and Hiby Digital M300. Tips: I tried Penon Liqueur Orange and Black, Divinus Velvet. used a couple of narrow borres as well but I don't know the name of them.
Tonalily: it leans towards a U shape sound. What makes quite an easy fit for most music genres. The DD stays in control and hasn't found many tracks where it lost its head or footing and became distorted in playback. The sound is little more focussed on the bass region then on the upper mids/treble but didn’t overshadow them in any chance
Bass: It packs a serious punch without being a basshead. The kick drums are nice. O my world the attack and decay are very good in the envelope Some might find it dry some prefer a wetter bass hit that each their own preference. Personally I didn't overpower or overshadow the mids and highs. I had multiple encounters in a couple of tracks that really felt the air move in my ear. Is there bleeding into the lower mids a little bit but it is very minor. It was more a couple on what type tips I used.
Mids: Even being a U shape the mids are transparent, clear. Instruments are very easy to listen to and are very well layered. In my simple guitar test it was still clear and not muffled. Even if you put a blacked on top of them to make them join the dark side. upper mids are very smooth there is maybe a -+5-6 dB of ear gain. What makes this also perfect for people who are sensitive about that part in iems. I found zero instances that this was fateging or shouty.
Treble: The treble really brings the resolution and clarity in the mix. In some instances I found it to be a little spicy that there was a firebreather afterwards just that little bit too much pepper in the soup some people like some don’t. If you don’t like that in your music well with a narrow bore tip you can reduce that a little but you're also enhancing the bass a little more then.
Timbre: Was very natural, especially in my little guitar test. It worked perfect for acoustic tracks and instruments where the soundstage is that little more intimate.
Soundstage: is really far above average. It has a really good depth and height, even width. Can usually tell there is the bassist there is the saxophone in the space specially in a good recording of Blue and Jazz. Even on rock song like i added 3 Doors Down in youtube link above.
Technicals; Solid layering, solid instrument separation. The micro details that can pick up that some sets leave behind the resolution is also good. i can’t really find fault
All said and done, The Kefine Delci, The Delci my god what a set this is for the price. This is a solid one to pick up. It is hard to find faults, The only nitpick I had with this set is: no 4.4mm termination and the tips that were for me slightly too flimsy so I couldn't get a proper seal. Decli Delci why you are so good and yet so cheap. My recommendation is to stick around for a while. I also think it gives other iems a run for their money even in the bracket above. I'm not a guy that’s gonna use the above price point easily but it's up there.

Good morning, readers! It is time for Kefine Delci!
Today we are going to talk about a new brand called Kefine, which is a SIVGA subbrand. Their first IEMs were planars at a very low cost. If you are interested, I recommend you take a look at the KEFINE Klanar.
The brand new ones are called Delci and are a single DD IEM with an excellent quality-to-price ratio. Their goal is to provide high-quality products at low prices, and they appear to be successful.
Thank you, Kefine, for sending me this unit to review.
I am not an audiophile; I am just a guy who enjoys trying out different IEMs and DACs and spending a lot of time listening to music.
So I will not use super-technical terms to review it, but I will do my best to describe it.
Tech Specs:
- Driver type: 10mm DLC + PU
- Frequency response: 20 Hz–20K Hz
- Sensitivity: 108 dB +/- 3 dB
- Impedance: 28 ohm +/-15%
- Plug size: 3.5mm SE
- Shell: CNC-machined aluminum
- Weight: 5.3 g for one side
Packaging:
The new packaging is noticeably more refined than the previous version. The Kefine Delci arrives in a very fine and elegant package, and this time it is well-equipped with accessories.
Inside, we find:
- A nice cable (only present with 3.5mm termination)
- 2 types of tips (7 pairs)
- A rigid case for transport
Finding a nice cable, absolutely high-quality tips, and a case for such a well-made IEM is truly impressive. The price is only 59 USD, and I do not recall seeing other IEMs with such a comprehensive package. KEFINE has surprised me because, despite being new and unknown, they have managed to keep their prices low. I would have preferred to be given the option of selecting a balanced cable; not much power is required, but a DAC/AMP is extremely beneficial.
Design/Build quality:
The Kefine Delci has a particularity compared to the competition, namely that the shell is not obtained from a mold but is CNC machined from aluminum blocks. In this way, the shells are extremely light and, above all, resistant; furthermore, the gunmetal finish should not present defects over time.
The design vaguely recalls those of the Klanar; the brand is on the faceplates and is clearly visible but not invasive; the shape of the shell is very ergonomic and, above all, compact; in terms of size, they are approximately the same as the Simgot EW200. In the part facing the inside of the ear, we have two ventilation holes; the rest is all sealed.
These types of shells are usually seen on higher-cost IEMs; the same is true for DLC + PU drivers.
Initial sound impression:
I noticed right away how similar the overall sound was to Klanar. They decided to stick with the same V-shaped philosophy (staying safe), which I like. If the Simgot EW200 or EPZ Q5 are too bright for you, this IEM could be the solution. As a very first test, I connected the Fosi SK02 to it and I will tell you that it wasn’t bad at all; it was actually a bright and powerful source with a warm IEM.
I gave it a quick listen, focusing primarily on the very full-bodied and energy-rich bass (a slight pressure in the ear canal is felt), and I noticed a very good soundstage. I began with a deep house playlist, and if the track requires a lot of bass, the Delci pushes extremely hard; in my opinion, it enters basshead territory. However, it manages to maintain a high level of detail in the trebles, with a hint of air.
Final sound impression:
Equipment used for testing the above
Device:
- iMac
- Redmi Note 7 (MIUI-Based)
- Poco M4 Pro
Software:
- Amazon music UHD 24bit 96kHz
- Tidal Hifi Plus
DAC:
- Moondrop Dawn Pro ( Good choice)
- Simgot DEW4X (extra refinement)
- EPZ TP50 (Audiophile combo)
- iBasso DC04 Pro (always good)
- Muse Hifi M4 (on-the-go option)
- Hidizs S9 Pro Plus (better mids)
- Fiio Ka11 (great pairing)
- Fosi SK02 (extra brillance)
After performing a bit of burn-in as usual, whether I needed it or not, the Kefine Delci immediately sounded good and I didn’t notice any extra improvements.
I started trying different dongles and some led to some improvements, especially in terms of depth. I personally stopped on the Fiio Ka11, which has excellent synergy with the Delci. The soundstage has literally opened up compared to the Creative Sfxi Amp; perhaps the greater power of the KA11 or simply the amplification stage, is more refined.
Of the original tips, I liked the wide-bore ones as usual, but it’s definitely a set that deserves some rolling tips.
The shells for my ears are decidedly small but in reality, it is not a problem at all, as you have more positioning possibilities and, above all, greater possibilities with different tips.
Kefine certainly got this model right, and I think many will like it.
Comfort & Fit:
If you have large ears, they may be small, but they should not cause you any problems. If you want them to be more external, consider getting tips like the DUNU S&S or Tri Clarion. In the photos, I am wearing Tri Clarion tips in size L.
Tips Rolling?
The originals are fine; you don’t necessarily have to buy other tips like on similar sets, but since I have a lot of tips to test, I decided to try playing with them a bit.
Divinus Velvet: I don’t know how but they are universal; any IEM I pair them with makes sense. In this case, they slightly reduce the bass pressure in the ear canal while keeping the sound almost unchanged. There are some small improvements in the high frequencies.
DUNU S&S: What a pleasure, Excellent combination. The Delci have a slightly short nozzle so even if the Dunu are a little longer, they don’t create any problems. Improved soundstage, slightly softer bass, and a slight recovery of medium and high frequencies.
Tri Clarion: If you want to keep your budget low, these tips are great on the Delci, and I honestly do not notice any loss of bass; in fact, because they are so wide, they do not compress the sound, and they keep the soundstage open. Excellent comfort.
Treble
Kefine Delci managed to maintain a certain brilliance on the high frequencies, although they remained in the safe zone. The driver has sparks, brightness, and even a bit of air. There is energy but even the most sensitive can tolerate it. The macro details are present and I would say that even some micro details manage to emerge. I was greatly surprised by these controlled trebles.
Mids
In terms of mids, I thought they were much more recessed. Although they are not protagonists, they are particularly natural and well represented. The mids feel thick, silky, and rich. Vocals are pitch correct but not tonally neutral. It’s an IEM that focuses a lot on the fun factor without losing too much seriousness. Excellent both male and female voices. Cymbals and musical instruments sound vivid and full of energy. There is a certain musicality.
Bass
Kefine has a decidedly heavy and abundant hand. The bass has great emphasis, transporting you to the dark side of the bass as soon as the track calls for it. I must say that they are fast and well defined for the quantity.
The subbass doesn’t have much roll-off and overpowers with harmony. I would describe him as nice, rich, and thunderous. Despite its weight, the driver manages to maintain a certain level of control even through complex tracks. If you are looking for something neutral, this IEM is not for you.
Soundstage and Imaging
Both the driver and the CNC-machined shell have resulted in accurate acoustics, and the soundstage is decidedly wide for the average. In this price range, I hadn’t yet tried the IEMs that Bassheads would like so for 59 USD, they are truly amazing. The image is very good, in some cases, it loses a bit of resolution but overall, it is really well done from several points of view.
Comparison:
vs EPZ Q5 & Simgot EW200
I have grouped them together as they are not comparable as they aim at two user targets that, in my opinion, are different. Here we are talking about very high-value IEMs, characterized by a bright and detailed sound signature. The bass sounds more natural and overall, it is less fun-oriented than the Kefine Delci. I can say that Delci easily competes with them but in the bassheads category.
vs EPZ x Tipsy Star One
The EPZ x Tipsy are the ones we can compare the most in terms of musicality. The Tipsy driver is 64 ohm with excellent scalability and is characterized by a totally dark background that highlights the track in the center. The shell is made of resin (with handmade details), and the accessories included are a little scarce for the cost but I must say that it still has something that makes me buy it. A slightly more balanced sound is characterized by less emphasis on subbass and a slightly more natural sound.
vs Kefine Klanar
I was forgetting to compare them with the Kefine Klanar; the planar driver has a much less accentuated but still very strong bass and sub-bass. If you have the opportunity to purchase both (both are excellent and cheap), you will notice how the DD provides a fuller bass, perhaps a little slower. The mids feel less recessed, and macro and micro details come out more easily from the tracks. It has another level of definition and resolution. However, it is noticeable that they come from the same brand, even if this is slightly more balanced.
Conclusion:
Kefine is proving to be a brand that knows what it’s doing, and despite following a safe path, the results are still worthy of note. The Kefine Delci enters the Simgot and EPZ markets, targeting the segment that loves full-bodied basses. The bass also has a lot of pressure in the ear canal; my left ear has become particularly sensitive to moving air so I’m pretty confident. If you are sensitive to the acoustic pressure exerted in the ear canal, these are certainly borderline; however, if bass & subbass is your secret love, this IEM will certainly be a joy. For 59 USD, you get a complete IEM, full of well-made accessories, a very light and robust CNC-machined shell, and a DLC + PU driver (more expensive than an LCP).
Congratulations to Kefine, who is following a decidedly successful path. Thanks to Collin Yang for sending me this unit to review. I am delighted with it and it will stay with me for future comparisons.

@drakar06 I don't own the HBB but I honestly believe the Delci are superior at least qualitatively. I believe some reviews have made comparisons.

Introduction!
Hello friends,today in our review we will look at dynamic headphones from Kefine.
And they come in a small box with very minimal design, just a picture of the headphones themselves and the name of this Delci model.
And on the back are the technical specifications, a 10 mm dynamic driver is responsible for the sound here, and the sensitivity is 108dB and they have a 28ohm impedance, and they are quite easy to drive.
Let's take a look at what's included!
The headphones here are completely made of metal, so they are quite light and I’m glad that they are not very large, and on the front panel there is a company logo and two compensation holes are located on the inside next to the markings of the left and right channels, there is also a standard 2-pin connector!
But the sound guide here is quite slightly elongated and has a very distinct side so that the ear pads cling here more reliably it performs its function perfectly and in general everything is fine with the fit, although it seems to me that the sound guide could be made longer for a better and tighter fit, at least in my case.
Accessories!
And all the accessories are in this great leather case with the company logo, and that's what we get.
(1) An excellent copper cable with 2-pin connectors and a 3.5 jack plug.
(2) Standard silicone tips.
(3) A manual in two languages and a quality control card.
How do these headphones sound?
Now we have come to the most important part of the review, an analysis of the sound of these amazing dynamic kefine delchi headphones, and I have been asked a lot about them lately, how do they sound, since there have been some disputes on this matter, but I hope After my review, you will have absolutely no questions and everything will be clear to you.
And I would like to start with the fact that the first thing I liked when I connected these headphones was this, that same neutral, very balanced tuning, with correctly emphasized bass with a very neat approach to the mids, and the upper mids were pulled up perfectly exactly according to my target...well, the high frequencies are just a fairy tale, they are very long lasting for purely dynamic headphones, it’s just some kind of beauty, you’ll agree, here the tuning was not bright for us, and the whole concept of tuning is very clear and familiar to me and in this regard I definitely appreciate respect to the manufacturer.
Low Frequencies:
Now let's start with the low frequencies, which here have a good volume and weight, a deep and well-developed subwoofer rumble but without obvious bassheading, and the bass here does not sound monotonous and its texture is very good, distortion is audible and all the harmonics are due to saturation and very transparent, that is, there is no turbidity here, but the only thing I would like to get is a more highlighted and punchy midbass since it feels a little relaxed on the attack, that very obvious highlighted impulse would not hurt here,but again, I don’t think that everyone will notice this and basically you pay attention to it only in hip-hop or electronic genres and provided you have good expensive reference headphones, but as for rock or metal, it’s orderly and I don’t think it will bother you , these are not the genres where it will be so significant since, as a rule, synthesizer basses are very rarely used there.
Mid Frequencies:
But at mid frequencies there is almost standard neutrality with a slight warm tone in the vocal part, and I like the way everything is presented here, the vocals are very clear, very slightly highlighted a little forward and do not take on too much attention, they sound very balanced and correctly staged with good transparency and optimal amount of air, there is no darkness here,dryness or an enclosed space where all the oxygen has been cut off to you, on the contrary, everything here is very breathable and the timbres here are very correct and practically do not have any extra color and unpleasant squeals of rustling or overtones, as happens especially in bright headphones with excessive amplification of this area, that is, a let down the result is that everything here is presented carefully with a little emotionality but without any excessive tediousness, since at the end we get a very immersive, atmospheric and smooth presentation that gives only positive emotions and in terms of attacks and transient processes, everything is fine here, since the snare drum does not feel blurred when hit and leaves behind long tails from reverberation, that is, this is in complete order.
High Frequencies:
But at high frequencies everything is doubly more interesting, I like that these headphones did not lead into the dark side, as is often the case with dynamic headphones at this price, but on the contrary, they literally revealed to us how much the driver potential allows, all the percussion cymbals and various small micro and macro details that you can only find in your compositions.
And as for me, what we get here is simply gorgeous analytics that are not hidden anywhere and no less lost technicality, that is, everything is exactly as I like, they gave us a little air, added transparency so that everything sounded more open, but also did not lose the main indicative moments at high frequencies. good headphones as a technician and analyst, at the same time, I will note that there is no sibilance of vile timbre or sonority, and again, as in the situation with averages, there is no additional gain or color observed here, and there is a small peak in the graph, but it just slightly does its job, but no more he has no goal of taking all the attention to himself and throwing all the hihats in our faces, as well as various nuances of recordings and mixing, that is, the headphones even play out some poorly recorded material quite cheerfully
Stage and stereo panorama:
But the sound stage surprised me from the first listening, damn, it’s beautiful, a gorgeous extended stereo panorama, that is, the balance between the channels is very good, everything sounds separate and all the plans are very detailed and don’t sound like one piece, but on the contrary, they are very clearly aligned in space among the dynamic headphones and at such a low cost it’s not so easy to find one.
My conclusion on this headphones:
Kefine Delci are simply super amazing, very balanced neutral dynamic headphones that fell in love with me immediately from the first listening, firstly with their competent and understandable tuning, and secondly with their super absorbing sound stage that literally takes you to another dimension.
Without any doubt, I recommend these headphones for purchase, and fans of such tuning will definitely appreciate them.

But at mid frequencies there is almost standard neutrality with a slight warm tone in the vocal part, and I like the way everything is presented here, the vocals are very clear, very slightly highlighted a little forward and do not take on too much attention, they sound very balanced and correctly staged with good transparency and optimal amount of air, there is no darkness here,dryness or an enclosed space where all the oxygen has been cut off to you, on the contrary, everything here is very breathable and the timbres here are very correct and practically do not have any extra color and unpleasant squeals of rustling or overtones, as happens especially in bright headphones with excessive amplification of this area, that is, a let down the result is that everything here is presented carefully with a little emotionality but without any excessive tediousness, since at the end we get a very immersive, atmospheric and smooth presentation that gives only positive emotions and in terms of attacks and transient processes, everything is fine here, since the snare drum does not feel blurred when hit and leaves behind long tails from reverberation, that is, this is in complete order.
High Frequencies:
But at high frequencies everything is doubly more interesting, I like that these headphones did not lead into the dark side, as is often the case with dynamic headphones at this price, but on the contrary, they literally revealed to us how much the driver potential allows, all the percussion cymbals and various small micro and macro details that you can only find in your compositions.
And as for me, what we get here is simply gorgeous analytics that are not hidden anywhere and no less lost technicality, that is, everything is exactly as I like, they gave us a little air, added transparency so that everything sounded more open, but also did not lose the main indicative moments at high frequencies. good headphones as a technician and analyst, at the same time, I will note that there is no sibilance of vile timbre or sonority, and again, as in the situation with averages, there is no additional gain or color observed here, and there is a small peak in the graph, but it just slightly does its job, but no more he has no goal of taking all the attention to himself and throwing all the hihats in our faces, as well as various nuances of recordings and mixing, that is, the headphones even play out some poorly recorded material quite cheerfully
Stage and stereo panorama:
But the sound stage surprised me from the first listening, damn, it’s beautiful, a gorgeous extended stereo panorama, that is, the balance between the channels is very good, everything sounds separate and all the plans are very detailed and don’t sound like one piece, but on the contrary, they are very clearly aligned in space among the dynamic headphones and at such a low cost it’s not so easy to find one.
My conclusion on this headphones:
Kefine Delci are simply super amazing, very balanced neutral dynamic headphones that fell in love with me immediately from the first listening, firstly with their competent and understandable tuning, and secondly with their super absorbing sound stage that literally takes you to another dimension.
Without any doubt, I recommend these headphones for purchase, and fans of such tuning will definitely appreciate them.

DISCLAIMER
I would like to thank KEFINE for providing this review unit.
The Delci can be gotten here: https://hifigo.com/products/kefine-delci or https://www.linsoul.com/products/kefine-delci (no affiliate links).
SPECIFICATIONS
ACCESSORIES
Other than the IEM, these are included:
- 3 pairs of wide-bore silicone eartips (S/M/L)
- 4 pairs of narrow-bore silicone eartips (S/M/L)
- Cable
- Carrying case
The accessories are very decent for a sub-$100 USD set, perhaps other than the lack of foam tips being a small nitpick.
We have 2 variants of silicone tips provided - the narrow-bore ones boost bass but compress soundstage a bit, whereas the wide-bore ones increase treble and air, with some soundstage improvement.
While we have no information on the exact cable materials, this stock cable is actually quite good for a budget IEM. It is well-braided, with minimal tangling and negligible microphonics. There is a chin cinch for added grip during usage. The cable only comes in a single-ended 3.5 mm termination, but it is no biggie for diehard audiophiles to pair an aftermarket balanced cable, with the detachable 2-pin housing.
Lastly, we have a semi-rigid leatherette zipper carrying case; it is tough to withstand compression, with inner webbing.
The rest of this review was done with the stock cable and stock narrow-bore silicone tips. No aftermarket accessories were used, so as not to add any confounders to the sound.
BUILD/COMFORT
The Delci is fashioned from aviation-grade CNC machined aluminum alloy. It is literally built like a tank, and comes in a steam punk-like gunmetal hue.
Each earpiece weighs a mere 5.3 g, and coupled with smooth inner aspects sans awkward protrusions, the Delci promises to be a comfortable proposition for longer listening sessions, in terms of ergonomics.
I didn't detect any driver flex on my pair, but this is partially dependent on ear anatomy and type of tips used. Even though this IEM is heavily vented, isolation is above average and it can be used in noisier environments.
INTERNALS
The Delci's engine is a 10 mm DLC + PU diaphragm dynamic driver.
DRIVABILITY
I tested the Delci with the following sources:
- Apple dongle
- Cayin RU7
- Chord Mojo 2
- Fiio KA11 dongle
- Fiio KA17 dongle
- Khadas Tone Board -> Schiit Asgard 3 amp
- Questyle M15 DAC/AMP dongle
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Sony Walkman NW WM1A DAP (Walkman One WM1Z Plus v2 Mod)
- Smartphone
This IEM is relatively easy to drive, and can be powered off a weak smartphone. But it will scale with amplification, in terms of bass tightness, dynamics and soundstage.
SOUND & TECHNICALITIES
Graph of the KEFINE Delci via IEC711 coupler. 8 kHz is a coupler artefact.
Sound wise, the Delci has a U-shaped tonality, which makes it quite compatible with a myriad of music genres.
This set is sub-bass focused, with a nice visceral rumble heard in sub-bass heavy tracks. The mid-bass is nevertheless very nimble, with no mid-bass smearing. Admittedly, texturing may be at times one-noted, but it can handily cope with fast complex bass tracks. For example, in Sting's Englishman In New York, at around 2:12 there is a double bass solo, which the Delci handles with aplomb.
The lower midrange is relatively transparent, allowing vocals and instruments to be easily layered on a dark background. With no more than 6 dB ear gain, upper mids and vocals are extremely non-fatiguing, with zero instances of "shout". The vocals are still forwards and are not drowned out in the mix - so not to worry - but the pinna-gain sensitive gang will be very home with this tuning choice.
The slight boost in the upper mids continues on with an elevated lower treble. This brings resolution and clarity to the table, though there are some instances of spiciness. Sibilance is just slight, but thankfully the narrow-bore eartips included in the packaging can tame the treble for the very treble-sensitive. The upper treble tails off, so it isn't the most airy IEM per se.
Timbre is very natural, and is a highlight on this set, for acoustic instruments in particular.
In terms of technicalities, the Delci boasts of an expansive soundstage in all 3 dimensions, especially when well juiced with amplification. Imaging is accurate, with solid instrument separation and layering. Micro-details and resolution are good in view of the boosted lower treble, no complaints here.
All in all, with the big sub-bass and slightly augmented lower treble, the Delci amalgamates musicality and technicalities nicely. It does not veer to either extreme - not being overly sterile and analytical, yet staying away from being too analogue-sounding.
COMPARISONS
Comparisons were made against other $50 - $100 USD single DDs. Planars, hybrids and BA types are omitted, as the different transducers have their own pros and cons.
Oriveti OD100
Graph of the Delci versus OD100 via IEC711 coupler. 8 kHz is a coupler peak.
The OD100 is a much brighter IEM, and is very shouty in the upper mids, due to an over zealous 14 dB ear gain! The OD100 also has a marked sub-bass roll-off, and is quite sibilant in the treble. Thus, perhaps only trebleheads will gravitate to the OD100's tuning, as it can be grating for other consumers in tonal balance.
The OD100 is much more sterile in note weight, and sounds rather metallic in timbre. The OD100 has weaker soundstaging and imaging, but has slightly sharper edge definition and clarity, which is perhaps a function of the brighter signature.
The OD100 can be worn cable down or over-ears due to a bullet shaped design, which slightly increases fit permutations.
Moondrop Aria 2
Graph of the Delci versus Aria 2 via IEC711 coupler. 8 kHz is a coupler peak.
The Aria 2 follows the virtual diffuse sound field (VDSF) - which is essentially Moondrop's in-house variant of the Harman curve. Its sound signature is on the thinner side, with an upper midrange boost - this provides a "clean" soundscape, but it can sound boring and a bit shouty in the upper mids, with a 9 dB ear gain. Bass is also less pronounced on the Aria 2.
The Aria 2 is thus more sterile sounding, with less dynamics on tap. In technicalities, the Aria 2 loses in soundstage and imaging, with micro-detailing about on par.
The Aria 2 is much heavier in weight, and may be uncomfortable to use for longer listening sessions.
Simgot EA500LM
Graph of the Delci versus EA500LM (3 tuning nozzles) via IEC711 coupler. 8 kHz is a coupler peak.
The EA500LM has 3 tuning nozzles, with all tuning permutations being much brighter - and fatiguing - in the upper mids. This IEM has slightly better versatility though, due to the aforementioned tuning nozzles, but upper mids-sensitive folk should be wary of the EA500LM as such.
The EA500LM sounds a bit more metallic in timbre. With the gold/red nozzle installed on the EA500LM (ie least fatiguing/shouty combination), technicalities like imaging and micro-detailing are about on par with the Delci, though the Delci is the winner in soundstage.
CONCLUSIONS
The KEFINE Delci is a stellar entrant to the ultra-competitive budget single DD market. At its current pricing of $50ish USD, there's a lot to like about it. Externally, accessories, build, drivability, comfort and isolation are quite impeccable (literally and figuratively).
Sound-wise, the Delci is no slouch, espousing a U-shaped tuning with huge sub-bass rumble, yet being quite nimble in the mid-bass. The upper midrange eschews the commonly-found shout-fest fanatical steroid-boost in CHIFI budget sets, being very sedate in this region. Timbre is extremely natural, which should please the most ardent of timbre-snobs, and the Delci excels at soundstage and imaging, beating some of the single DD benchmarks in this arena.
I would have preferred a hair better texturing in the bass, but can close an eye considering its modest pricing. The lower treble is on the brighter side, and can be a tinge spicy, but thankfully, the provided narrow-bore eartips can mitigate this frequency band, even for my treble-sensitive ears.
In a nutshell, the Delci is an excellent budget single DD that I would heartily recommend for newcomers to the hobby, or even for those that want to sample something that blends musicality and technicalities adeptly, with no shouty upper midrange to boot.

INTRODUCTION:
Buckle up, fellow audiophiles, because we're about to dive headfirst into the latest offering from Kefine! Remember the Klanar? That planar wonder that dropped jaws with its killer sound and budget-friendly price tag? Well, Kefine's back for another round, this time throwing their hat into the crowded sub-$100 IEM ring with the Delci. Did they make the smart move venturing into this hotly contested territory? Will the Delci manage to carve out its own niche in this cutthroat price bracket? Let's separate the wheat from the chaff and see if the Delci has the chops to impress! So, clear your ears and prepare to be transported to sonic bliss!
FOREWORD:
The gear on hand has undergone at least 10-15 hours of use before it was assessed.
No EQ is ever applied in my reviews.
For the sake of convenience, I try my best to use a stock setup. Not everyone has access to personal ear tips or cables. If personal ear tips, cables, or accessories are used, you will be notified.
As I try to be objective, my claims inevitably will be subjective and biased to my personal preference. I cannot stress more that you should take this with a grain of salt for we have different perceptions to sound and what we hear.
SPECIFICATIONS:
Maker: Kefine
Model: Delci
Drivers: 10mm DLC+PU dynamic driver
Impedance: 28 ohms
Sensitivity: 108db
PACKAGING & DETAILS:
Ah, the Delci's packaging - no bells and whistles, just a down-to-earth black box. It's clear Kefine's prioritizing the sound over the spectacle, which I can respect. Let's be honest, in this price range, fancy boxes are like icing on a stale cake. Sure, unboxing can be a fun little ritual, but for a sub-$100 IEM, I'd rather Kefine focus on what truly matters: the sonic experience. After all, as the saying goes, you can't polish a turd, and sometimes, all that glitters isn't gold. Let's hope the Delci's sound is more like a hidden gem than a dime-a-dozen dud.
CASE:
The Delci's carrying case isn't exactly winning any beauty contests. It's your standard, no-frills affair. But hey, at this price point, I'd be singing a different tune if there wasn't one included at all. Let's face it, a halfway decent case is the cherry on top for a sub-$100 IEM. Sure, it might not be the most glamorous, but it gets the job done – keeps those precious Delcis safe from getting tossed around in your bag like yesterday's news. In this case, beggars can't be choosers, and I'm happy Kefine at least threw us a bone.
EAR TIPS:
Kefine seems to be following the "if it ain't broke, don't fix it" philosophy with the Delci's ear tips. Just like the Klanar, they've included a generous spread of different sizes. Now, differentiating between the regulars and wide bores can be a bit of a treasure hunt – they all look pretty similar. Here's a pro tip: feel is your friend! The wide bores tend to be a tad softer, so give them a little squish to tell them apart. As for quality, the stock tips are decent enough to get you started. But hey, if you're a seasoned audiophile who's mastered the art of "tip rolling," feel free to throw on your favorite premium pair and see where the sonic journey takes you!
BUILD:
Let's be honest, I'm no watchmaker, but Kefine seems to have pulled off some serious engineering magic with the Delci's housing. They're using CNC machining, which basically means computer-controlled precision cutting, to craft these beauties. No wonder they're bragging about the quality at such a wallet-friendly price! Picking them up, they feel surprisingly premium – solid and smooth, like something way out of their sub-$100 league. Kefine even throws some shade (without naming names, of course) about how these are built to last, unlike certain other IEMs that turn into chipped paint nightmares after a single tumble. Looks like Kefine put their money where their mouth is, and that's music to my ears!
APPEARANCE:
The Delci might be the Klanar's doppelganger at first glance, but a closer inspection reveals some subtle distinctions. The Delci's sculpted form is noticeably more petite than its predecessor, making it even more comfortable for extended listening sessions. The color scheme takes a turn too, with the Delci sporting a sophisticated dark brown chrome that exudes a touch more elegance than the Klanar's classic black. While the overall layout might share some similarities, the Delci's refined design edges out the Klanar in the looks department, at least in my humble opinion. While a part of me yearns for a complete design overhaul, the Delci's understated improvements undeniably elevate its visual appeal.
COMFORT:
The Delci aces the comfort test! These little guys are light as a feather, nestling snugly in your ears without any pressure or fatigue. The fit is secure, creating a good seal that blocks out unwanted noise. They're so comfortable, I even managed to snag a snooze with them in – that's the ultimate comfort test, folks! Let's just say, if you're looking for an IEM that disappears into your ears and lets the music take center stage, the Delci definitely delivers.
CABLE:
The Delci's stock cable is a bit of a mixed bag. It's on the lighter side, which some might find appealing. Kefine gets points for the color choice though – it complements the IEMs nicely.
SOUND IMPRESSIONS:
For this review, I hooked up the Delci to a variety of sources to see how they performed. This included some heavy hitters like the Ovidius B1 and Cayin RU6, as well as some more portable options like the Fiio M11 Plus LTD and Oppo A94. To keep things interesting, I used a mix of streaming services (Qobuz and Apple Music) and my own FLAC collection. Basically, I threw everything but the kitchen sink at these IEMs!
TECHNICALITIES:
The Delci boasts an impressive soundstage for its price point. It offers a surprisingly spacious presentation, exceeding expectations for a sub-$100 IEM. This translates to a well-defined separation of instruments and vocals, creating a clear and layered listening experience. The spaciousness enhances the overall presentation, fostering a sense of immersion that rivals more expensive models.
The Delci's imaging is a revelation in the sub-$100 realm. Usually, with budget IEMs, you get what you pay for, and that often means a homogenous sonic mush. But the Delci throws a curveball. I found myself constantly surprised, discovering previously unheard details and instrument placements in tracks I thought I knew by heart. It's like rediscovering your favorite record store – you never know what hidden gem you might unearth! This precise and nuanced imaging is a true strength of the Delci, making it stand out from the crowd in its price bracket.
The Delci's Achilles heel, for some listeners, might be its texture. It leans towards a smoother presentation, which can leave certain instruments, particularly bass and guitars, lacking a touch of that raw, textured "bite" some audiophiles crave. Think of it like a beautifully restored vintage car – sleek and elegant, but maybe missing the subtle imperfections that tell the story of its journey. However, it's important to remember that this smoothness falls well within the realm of satisfying resolution and detail. Ultimately, it boils down to personal preference. If you prioritize a ruthlessly analytical sound signature, the Delci might not be your end-all, be-all. But for those who appreciate a smooth and refined presentation, the Delci delivers in spades.
The Delci truly shines when it comes to timbre. As expected from a single dynamic driver design, it delivers a refreshingly natural and organic presentation. Vocals and instruments possess a lifelike quality, free from artificial coloration. This translates to an incredibly engaging and soulful listening experience. While some might argue the Delci leans slightly towards genres like jazz and classical, where its natural timbre can truly flourish, it handles a wide variety of musical styles with remarkable ease. No matter your musical preference, the Delci's smooth and accurate timbre will ensure your music remains rich, detailed, and utterly captivating.
BASS:
The Delci prioritizes subbass, delivering deep, impactful rumbles. While the midbass is less prominent, it remains well-controlled and doesn't overpower the sound. Overall, the bass is agile and responsive, handling intricate basslines with ease. This emphasis on bass might not suit listeners who prefer a neutral sound signature, but bass enthusiasts are likely to enjoy the Delci's powerful bass presentation.
MIDRANGE:
The Delci's sound signature definitely isn't neutral – the mids are lush, rich, and full-bodied, with a warm presentation that keeps the details and transients clear. Instruments sound great, but the vocals are a bit recessed, making the overall soundstage wider. I would've liked them to be a bit more forward, but it wasn't enough to bother me – overall, the mids are still good.
TREBLE:
Kefine impressed me with the treble on the Delci. Initially, I worried the safe tuning might mean a lack of energy in the highs. But to my surprise, the treble delivers a surprising amount of detail, shimmer, and sparkle when the music calls for it. It's still on the safe side, which is great for people who are sensitive to harsh sounds (sibilance). Crashes, cymbals, bells, and hi-hats all come through with a nice balance of liveliness and control.
COMPARISONS:
Simgot EA500
The EA500 undoubtedly boasts a brighter soundscape. It excels in note definition, offering crisp, well-defined edges. However, this brilliance comes at the cost of a narrower soundstage. In comparison, the Delci presents a more natural timbre, faithfully reproducing the intended sonic character of instruments. While the EA500's modular tuning nozzles provide greater flexibility for sculpting the sound to your preference, the Delci takes the cake for pure listening enjoyment. It's undeniably addictive, offering a highly engaging experience that the EA500, despite being a long-standing benchmark for the $100 price point, can't quite match. The EA500 might leave you fatigued after extended listening sessions, whereas the Delci strikes a perfect balance between sonic pleasure and technical prowess. While the EA500 might have the edge in pure resolution, the Delci wins hearts with its ability to keep you glued to your music for hours on end.

The Titan S is the epitome of neutrality – balanced across the frequency spectrum, almost to a fault. While this meticulous approach unveils hidden details with impressive clarity, it can sometimes leave you wanting more. You might crave a touch more bass punch, a hint of midrange warmth, or a dash of treble sparkle. This neutrality, however, makes the Titan S a technical marvel, a pristine window into the recording itself.
The Delci, on the other hand, injects a shot of vibrancy into your music. It prioritizes fun and engagement, adding a touch of color to the sonic canvas. While the Titan S boasts superior technical prowess, the Delci's ability to keep you captivated and wanting more is undeniable. It sacrifices some technical perfection for a more emotionally involving listening experience. The choice boils down to your preference: surgical precision or infectious musicality.
Stay tuned, audiophile friends! I'll be diving into comparisons between the Delci and other contenders in the near future. We'll have showdowns with the EPZ Q1 Pro and the Orivetti OD100, dissecting their sonic personalities to help you, the discerning listener, pick your perfect match.

VERDICT:
The Delci undeniably checks most of the boxes for a stellar IEM. While a touch more resolution, textural detail, and a slightly forward vocal presence would be the icing on the cake, these are minor quibbles when considering the big picture. Kefine masterfully prioritized the right elements, crafting an IEM that prioritizes enjoyment without sacrificing technical merit. At a wallet-friendly $60 price tag, the Delci is a clear winner. It delivers a fantastic balance of accurate timbre and technical prowess, even if it doesn't excel in every single aspect. But that's the beauty of it – Kefine made the right choices, prioritizing what truly matters for a truly engaging listening experience.
A huge thank you to
Collin Yang of Kefine for their continued generosity in providing the Delci for this review.
Buckle up, fellow audiophiles, because we're about to dive headfirst into the latest offering from Kefine! Remember the Klanar? That planar wonder that dropped jaws with its killer sound and budget-friendly price tag? Well, Kefine's back for another round, this time throwing their hat into the crowded sub-$100 IEM ring with the Delci. Did they make the smart move venturing into this hotly contested territory? Will the Delci manage to carve out its own niche in this cutthroat price bracket? Let's separate the wheat from the chaff and see if the Delci has the chops to impress! So, clear your ears and prepare to be transported to sonic bliss!
FOREWORD:
The gear on hand has undergone at least 10-15 hours of use before it was assessed.
No EQ is ever applied in my reviews.
For the sake of convenience, I try my best to use a stock setup. Not everyone has access to personal ear tips or cables. If personal ear tips, cables, or accessories are used, you will be notified.
As I try to be objective, my claims inevitably will be subjective and biased to my personal preference. I cannot stress more that you should take this with a grain of salt for we have different perceptions to sound and what we hear.
SPECIFICATIONS:
Maker: Kefine
Model: Delci
Drivers: 10mm DLC+PU dynamic driver
Impedance: 28 ohms
Sensitivity: 108db
PACKAGING & DETAILS:
Ah, the Delci's packaging - no bells and whistles, just a down-to-earth black box. It's clear Kefine's prioritizing the sound over the spectacle, which I can respect. Let's be honest, in this price range, fancy boxes are like icing on a stale cake. Sure, unboxing can be a fun little ritual, but for a sub-$100 IEM, I'd rather Kefine focus on what truly matters: the sonic experience. After all, as the saying goes, you can't polish a turd, and sometimes, all that glitters isn't gold. Let's hope the Delci's sound is more like a hidden gem than a dime-a-dozen dud.
CASE:
The Delci's carrying case isn't exactly winning any beauty contests. It's your standard, no-frills affair. But hey, at this price point, I'd be singing a different tune if there wasn't one included at all. Let's face it, a halfway decent case is the cherry on top for a sub-$100 IEM. Sure, it might not be the most glamorous, but it gets the job done – keeps those precious Delcis safe from getting tossed around in your bag like yesterday's news. In this case, beggars can't be choosers, and I'm happy Kefine at least threw us a bone.
EAR TIPS:
Kefine seems to be following the "if it ain't broke, don't fix it" philosophy with the Delci's ear tips. Just like the Klanar, they've included a generous spread of different sizes. Now, differentiating between the regulars and wide bores can be a bit of a treasure hunt – they all look pretty similar. Here's a pro tip: feel is your friend! The wide bores tend to be a tad softer, so give them a little squish to tell them apart. As for quality, the stock tips are decent enough to get you started. But hey, if you're a seasoned audiophile who's mastered the art of "tip rolling," feel free to throw on your favorite premium pair and see where the sonic journey takes you!
BUILD:
Let's be honest, I'm no watchmaker, but Kefine seems to have pulled off some serious engineering magic with the Delci's housing. They're using CNC machining, which basically means computer-controlled precision cutting, to craft these beauties. No wonder they're bragging about the quality at such a wallet-friendly price! Picking them up, they feel surprisingly premium – solid and smooth, like something way out of their sub-$100 league. Kefine even throws some shade (without naming names, of course) about how these are built to last, unlike certain other IEMs that turn into chipped paint nightmares after a single tumble. Looks like Kefine put their money where their mouth is, and that's music to my ears!
APPEARANCE:
The Delci might be the Klanar's doppelganger at first glance, but a closer inspection reveals some subtle distinctions. The Delci's sculpted form is noticeably more petite than its predecessor, making it even more comfortable for extended listening sessions. The color scheme takes a turn too, with the Delci sporting a sophisticated dark brown chrome that exudes a touch more elegance than the Klanar's classic black. While the overall layout might share some similarities, the Delci's refined design edges out the Klanar in the looks department, at least in my humble opinion. While a part of me yearns for a complete design overhaul, the Delci's understated improvements undeniably elevate its visual appeal.
COMFORT:
The Delci aces the comfort test! These little guys are light as a feather, nestling snugly in your ears without any pressure or fatigue. The fit is secure, creating a good seal that blocks out unwanted noise. They're so comfortable, I even managed to snag a snooze with them in – that's the ultimate comfort test, folks! Let's just say, if you're looking for an IEM that disappears into your ears and lets the music take center stage, the Delci definitely delivers.
CABLE:
The Delci's stock cable is a bit of a mixed bag. It's on the lighter side, which some might find appealing. Kefine gets points for the color choice though – it complements the IEMs nicely.
SOUND IMPRESSIONS:
For this review, I hooked up the Delci to a variety of sources to see how they performed. This included some heavy hitters like the Ovidius B1 and Cayin RU6, as well as some more portable options like the Fiio M11 Plus LTD and Oppo A94. To keep things interesting, I used a mix of streaming services (Qobuz and Apple Music) and my own FLAC collection. Basically, I threw everything but the kitchen sink at these IEMs!
TECHNICALITIES:
The Delci boasts an impressive soundstage for its price point. It offers a surprisingly spacious presentation, exceeding expectations for a sub-$100 IEM. This translates to a well-defined separation of instruments and vocals, creating a clear and layered listening experience. The spaciousness enhances the overall presentation, fostering a sense of immersion that rivals more expensive models.
The Delci's imaging is a revelation in the sub-$100 realm. Usually, with budget IEMs, you get what you pay for, and that often means a homogenous sonic mush. But the Delci throws a curveball. I found myself constantly surprised, discovering previously unheard details and instrument placements in tracks I thought I knew by heart. It's like rediscovering your favorite record store – you never know what hidden gem you might unearth! This precise and nuanced imaging is a true strength of the Delci, making it stand out from the crowd in its price bracket.
The Delci's Achilles heel, for some listeners, might be its texture. It leans towards a smoother presentation, which can leave certain instruments, particularly bass and guitars, lacking a touch of that raw, textured "bite" some audiophiles crave. Think of it like a beautifully restored vintage car – sleek and elegant, but maybe missing the subtle imperfections that tell the story of its journey. However, it's important to remember that this smoothness falls well within the realm of satisfying resolution and detail. Ultimately, it boils down to personal preference. If you prioritize a ruthlessly analytical sound signature, the Delci might not be your end-all, be-all. But for those who appreciate a smooth and refined presentation, the Delci delivers in spades.
The Delci truly shines when it comes to timbre. As expected from a single dynamic driver design, it delivers a refreshingly natural and organic presentation. Vocals and instruments possess a lifelike quality, free from artificial coloration. This translates to an incredibly engaging and soulful listening experience. While some might argue the Delci leans slightly towards genres like jazz and classical, where its natural timbre can truly flourish, it handles a wide variety of musical styles with remarkable ease. No matter your musical preference, the Delci's smooth and accurate timbre will ensure your music remains rich, detailed, and utterly captivating.
BASS:
The Delci prioritizes subbass, delivering deep, impactful rumbles. While the midbass is less prominent, it remains well-controlled and doesn't overpower the sound. Overall, the bass is agile and responsive, handling intricate basslines with ease. This emphasis on bass might not suit listeners who prefer a neutral sound signature, but bass enthusiasts are likely to enjoy the Delci's powerful bass presentation.
MIDRANGE:
The Delci's sound signature definitely isn't neutral – the mids are lush, rich, and full-bodied, with a warm presentation that keeps the details and transients clear. Instruments sound great, but the vocals are a bit recessed, making the overall soundstage wider. I would've liked them to be a bit more forward, but it wasn't enough to bother me – overall, the mids are still good.
TREBLE:
Kefine impressed me with the treble on the Delci. Initially, I worried the safe tuning might mean a lack of energy in the highs. But to my surprise, the treble delivers a surprising amount of detail, shimmer, and sparkle when the music calls for it. It's still on the safe side, which is great for people who are sensitive to harsh sounds (sibilance). Crashes, cymbals, bells, and hi-hats all come through with a nice balance of liveliness and control.
COMPARISONS:
Simgot EA500
The EA500 undoubtedly boasts a brighter soundscape. It excels in note definition, offering crisp, well-defined edges. However, this brilliance comes at the cost of a narrower soundstage. In comparison, the Delci presents a more natural timbre, faithfully reproducing the intended sonic character of instruments. While the EA500's modular tuning nozzles provide greater flexibility for sculpting the sound to your preference, the Delci takes the cake for pure listening enjoyment. It's undeniably addictive, offering a highly engaging experience that the EA500, despite being a long-standing benchmark for the $100 price point, can't quite match. The EA500 might leave you fatigued after extended listening sessions, whereas the Delci strikes a perfect balance between sonic pleasure and technical prowess. While the EA500 might have the edge in pure resolution, the Delci wins hearts with its ability to keep you glued to your music for hours on end.
Dunu Titan S
The Titan S is the epitome of neutrality – balanced across the frequency spectrum, almost to a fault. While this meticulous approach unveils hidden details with impressive clarity, it can sometimes leave you wanting more. You might crave a touch more bass punch, a hint of midrange warmth, or a dash of treble sparkle. This neutrality, however, makes the Titan S a technical marvel, a pristine window into the recording itself.
The Delci, on the other hand, injects a shot of vibrancy into your music. It prioritizes fun and engagement, adding a touch of color to the sonic canvas. While the Titan S boasts superior technical prowess, the Delci's ability to keep you captivated and wanting more is undeniable. It sacrifices some technical perfection for a more emotionally involving listening experience. The choice boils down to your preference: surgical precision or infectious musicality.
Stay tuned, audiophile friends! I'll be diving into comparisons between the Delci and other contenders in the near future. We'll have showdowns with the EPZ Q1 Pro and the Orivetti OD100, dissecting their sonic personalities to help you, the discerning listener, pick your perfect match.
