TinHifi has steadily carved its niche in the budget audio world. They've consistently offered IEMs with commendable performance at affordable prices, and many of us have likely experienced one or two of their models over the years. Some of their notable releases include the T2, T3, and the original C3, all of which garnered praise for their sound quality relative to their cost. With the C3 MKII, TinHifi aims to build upon this legacy and deliver another compelling option in the budget segment.
Box Contents:
Unboxing Experience:
The IEMs arrived in a compact and sturdy box, with the C3 MKII units themselves in the storage case. Inside, I found a selection of ear tips in various sizes, which is always a welcome sight. The included carrying case was a bit larger than I expected, but hey, who am I to complain about extra space? It's perfect for storing the IEMs, extra tips, and even a small dongle if needed.
I'm not quite sure what TinHifi means by 'High Sex Energy' when describing the N52 neodymium magnet in the C3 MKII's driver. I'm assuming in less colorful terms, means it's a strong magnet that contributes to the driver's dynamic performance.
Design and Build:
The C3 MKII has an understated design. The resin shells have a smooth, polished finish that feels nice to the touch. They're not overly flashy, but they have a certain elegance to them. The shells feel robust for an IEM in this price range. The resin shells seem durable and I've been using them for a while now, and they've held up well to daily wear and tear.
Speaking of the cable, it's a fairly standard affair. It's black, relatively thin, and feels reasonably durable. While it's not the most premium cable I've encountered in this price bracket (I'm looking at you Dunu), it gets the job done without any fuss. The 3.5mm termination feels sturdy, and the y-split and chin slider are functional, though the slider can be a bit loose. I would have preferred a slightly tighter slider to keep it in place, but it's a minor quibble.
Wearing Comfort:
Comfort is paramount when it comes to IEMs, and the C3 MKII doesn't disappoint. The lightweight design and ergonomic shape make them disappear into my ears. I've worn them for hours on end without any discomfort. The ear tips create a good seal, which is crucial for both comfort and sound isolation.
One thing to note is that the C3 MKII is designed for a deeper fit. This might not be ideal for everyone, but I personally found it to be very comfortable and secure.
Driveability:
Although I could not find the impedance or sensitivity numbers anywhere, the C3 MKII is a breeze to drive. It's sensitive enough to be powered by most sources, including Type C to 3.5mm dongles. I've used them with my Google Type C to 3.5mm dongle, DC Elite and a dedicated DAP, and they've performed admirably with each. No need for a crazy powerful amp here!
Sound Analysis:
Tonality
The C3 MKII greets you with a balanced sound signature, but there's a subtle warmth that permeates the entire frequency spectrum, making it enjoyable for long listening sessions. This balanced approach makes it incredibly versatile across genres, handling everything from acoustic jazz to electronica with grace.
Sub Bass
The sub-bass on these IEMs is surprisingly potent for the price point, reaching down into the depths without ever becoming boomy or overpowering. It's clean, controlled, and adds a satisfying weight to bass-heavy tracks. Listening to "Limit to your love" by James Blake, I was genuinely impressed by how well the C3 MKII handled the deep, rumbling bassline. It maintained its composure even when things got intense, allowing the sub-bass to shine without muddying the rest of the mix.
While the sub-bass extension is commendable, hardcore bassheads might find themselves yearning for a bit more rumble and slam. In tracks like "Why so serious?" by Hans Zimmer, where the sub-bass frequencies are prominent and intended to be felt as much as heard, the C3 MKII's sub-bass, while present, lacks the visceral impact that some might desire.
Mid-bass
Ah, the mid-bass, where the C3 MKII's warmth truly comes alive! It's punchy, textured, and adds a delightful thump to kick drums and basslines. The decay is on the slightly slower side, which contributes to the overall warmth and fullness of the sound. This is where I personally feel the C3 MKII shines. "Madness" by Muse, with its driving bassline, absolutely slaps on these IEMs! The mid-bass provides that extra oomph that makes you want to tap your feet and nod your head.
In some instances, this slightly slower decay can lead to a minor lack of separation in busy tracks. In songs like "YYZ" by Rush, where the bass guitar and kick drum intertwine in intricate patterns, the C3 MKII might not offer the absolute cleanest separation between the two.
Lower Midrange
The lower midrange is where the magic of male vocals happens, and the C3 MKII doesn't disappoint! It's well-balanced and present, providing a solid foundation for those baritone voices and instruments that occupy this range. Listening to Johnny Cash's "Hurt," I was captivated by the richness and depth of his voice. The C3 MKII rendered his vocals with a natural warmth and presence that sent shivers down my spine.
While male vocals generally sound fantastic, some instruments in the lower midrange, like cellos, can occasionally sound a tad thick. In orchestral pieces like "Jupiter" from Gustav Holst's "The Planets," the cellos, while still enjoyable, lacked a bit of the definition and texture that I would have preferred.
Upper Midrange
The upper midrange is where female vocals and instruments like violins and trumpets take center stage. Thankfully, the C3 MKII handles this region with finesse. It's clear, detailed, and never harsh or fatiguing. In "Hide and Seek" by Imogen Heap, her ethereal vocals soar through the mix with incredible clarity and emotion.
One minor observation is a slight dip around the 4kHz mark, which can sometimes result in a subtle lack of presence for certain female vocals and instruments in that specific range. For example, in "Running Up That Hill" by Kate Bush, her vocals, while still clear and enjoyable, lacked a bit of the bite and edge that I'm accustomed to hearing.
Lower Treble
The lower treble is where things start to get sparkly! The C3 MKII strikes a good balance here, providing ample presence and detail without ever veering into harshness or sibilance. Cymbals shimmer, hi-hats sparkle, and there's a lovely sense of airiness to the overall presentation. Listening to "Take Five" by Dave Brubeck, I was tapping my feet along with the crisp percussion and vibraphone.
It's worth noting that the lower treble can occasionally exhibit a slightly uneven response, with some peaks and dips that might become noticeable with certain recordings. In "Kashmir" by Led Zeppelin, the cymbal crashes, while generally well-rendered, occasionally displayed a slightly splashy quality.
Upper Treble
Now, let's reach for the stars—the upper treble! The C3 MKII extends well, providing a good amount of sparkle and air without becoming harsh or fatiguing. It's like a sprinkle of fairy dust on the music, adding that extra bit of magic. In "Violin Concerto No. 1" by Max Bruch, the C3 MKII beautifully captured the delicate nuances and overtones of the violin, creating a truly captivating listening experience.
While the upper treble extension is good, it's not the absolute best I've heard. In tracks like "The Great Gig in the Sky" by Pink Floyd, where the upper treble frequencies are crucial for creating a sense of space and atmosphere, the C3 MKII's performance was slightly less impressive. The sense of air and sparkle was present, but it lacked the ultimate extension and "shimmer" that I've experienced with some higher-end IEMs.
Soundstage
The soundstage on the C3 MKII is surprisingly spacious for an IEM in this price range. It's not quite an out-of-head experience, but it definitely doesn't feel cramped or confined. There's a decent amount of width and depth, and the imaging is surprisingly accurate. Listening to "Stimela" by Hugh Masekela, I was pleasantly surprised by how well the C3 MKII placed the various instruments in the mix. It created a sense of space and depth that added to the overall listening experience.
The soundstage height, however, is somewhat limited, which can sometimes make the presentation feel a bit two-dimensional. In orchestral pieces like "Symphony No. 5" by Beethoven, where the vertical placement of instruments is crucial for creating a sense of scale and grandeur, the C3 MKII's soundstage felt a bit flat.
Layering and Separation
The C3 MKII does a commendable job of layering and separating instruments, especially considering its price point. It's not the last word in resolution, but it manages to keep things organized even in busy passages. In "Bohemian Rhapsody" by Queen, the C3 MKII deftly navigated the complex arrangement, allowing me to appreciate the individual layers of vocals and instruments without them becoming a jumbled mess.
When pushed to its limits with extremely dense and complex tracks like "The Dance of Eternity" by Dream Theater, the C3 MKII's layering and separation capabilities start to show their limitations. While it still manages to keep the presentation from falling apart completely, some finer details and nuances might get lost in the mix.
Timbre
The timbre of the C3 MKII is largely natural and realistic, which is always a welcome quality in any audio gear. Instruments and vocals sound believable, without any glaring colorations or unnatural textures. Listening to "Hallelujah" by Leonard Cohen, I was moved by the raw emotion in his voice, which the C3 MKII reproduced with remarkable fidelity.
There's a slight hint of metallic sheen to the timbre, particularly in the upper midrange and lower treble. This is a minor nitpick, and it doesn't detract significantly from the overall listening experience, but it's something that I noticed with critical listening.
Coherence
The C3 MKII exhibits good coherence across the entire frequency spectrum. The different frequency ranges blend together seamlessly, creating a unified and harmonious presentation. In "Stairway to Heaven" by Led Zeppelin, the C3 MKII demonstrated excellent coherence, allowing the track to flow effortlessly from the quiet acoustic intro to the powerful climax.
The slight emphasis in the mid-bass and the occasional peaks and dips in the lower treble can sometimes introduce a minor disconnect between those specific regions and the rest of the frequency spectrum. This is a subtle observation, and it doesn't significantly impact the overall coherence, but it's something that I noticed with critical listening.
Detail Retrieval
The C3 MKII is a decent performer when it comes to detail retrieval. It's not the most resolving IEM out there, but it manages to unearth a good amount of musical information without ever sounding analytical or clinical. In "Teardrop" by Massive Attack, the C3 MKII revealed subtle textures in the strings and nuances in the vocals that I hadn't noticed before.
Compared to other IEMs in its price range, the C3 MKII holds its own. It doesn't necessarily outperform all its competitors, but it certainly doesn't fall behind. It strikes a good balance between detail retrieval and musicality, making it an enjoyable listen for a variety of genres.
Conclusion:
So, where does the TinHifi C3 MKII stand in the grand scheme of things? Well, the budget IEM market is a battlefield, with new contenders emerging constantly. It takes something special to stand out from the crowd, and I think the C3 MKII has a tuning that's fairly to be unremarkable in this price range. What does set the C3 MKII apart is its overall value proposition. It's not just about a single standout feature; it's about the whole package. You get a balanced and enjoyable sound signature, a comfortable fit, a robust build, and all this at a price that won't break the bank. That's a combination that's hard to beat!
Sure, it's not perfect. There are IEMs with more impactful bass, a wider soundstage, or a higher level of detail retrieval. But at this price point, it's about finding the right balance of strengths, and the C3 MKII does decently well.

TinHiFi C3 MKII :: $49.99 :: 1DD
Huge thanks to 'GoodSound Audio Store' for providing a sample unit for this review.
However, this review fully reflects the my honest opinion without anyone else's interference.
> Link to original review in Korean
-
TinHiFi is a Chinese earphone brand that was born in 2017, started by a company that has been making earphones for other companies for quite some time.
It's not an exaggeration to say that they've been around since the beginning of Chi-Fi wave. Their bullet-shaped T2 / T3 models have enjoyed quite a bit of popularity, even being sold at the DROP.
The TinHiFi C3 MKii is the successor to the C3 model launched back in 2023.
It is said to offer great sound from its newly designed 10mm LCP dynamic driver and is comfortable to wear thanks to its compact and lightweight design, weighing just 4.1g.
It's another IEM with 1DD configuration that has been a long-standing favourite of TinHiFi, and I was very curious to see if it can become another entry-level pick, especially since it's so affordable at a retail price of less than $50.

Package & Build


This is the package of TinHiFi C3 MKii.
When you open the box, you can see all the accessories are inside a large case. This generously sized hard case is quite good in quality. It's not bad to have such a practical package without spending a fortune on it.
You'll get :
- TinHiFi C3 MKii Unit
- 6 pairs of silicone eartips
- 2 pairs of replacement nozzle filter
- Carrying case
- Warranty card


The accessories that come with the C3 MKII is quite decent at the price point.
There are six pairs of silicone eartips, two each in small, medium and large sizes. The outer walls are a bit too thin, which can make them feel a little flimsy, but overall, there are no major complaints about the shape or material.
The included cable is pretty good, with a thin, lightweight, easy-to-handle wire that's fairly comfortable to wear, and the quality of the various terminals, splitters, and other components is above average. For the price point, I think it's a pretty nice cable.


Like its predecessor, The C3 MKII emphasises the ‘small, lightweight unit design for superior comfort’.
You can see that they've managed to keep the unit as small as possible while remaining the area where the drivers are placed.
At the top of the unit, you'll notice a slight protrusion inwards. It will sit naturally inside your ear to keep the unit securely in place on the auricle.
It's a design element that some people may or may not like, but the protrusion isn't severe enough that it shouldn't be uncomfortable for most users.
It fits quite nicely in my ear, and I think rest of users will feel the same comfort.


Unlike its predecessor with carbon-fiber design, the C3 MKII has a more natural-grained carbon backdrop underneath, topped with a silver, shimmering star decoration.
I personally think it's a nice design that's neither too boring nor overdone.
The nozzle isn't made out of a separate piece, but is moulded from the same resin from the unit.
It has a metal sticker on the end to prevent debris from getting in, and is 5.2mm to 6mm thick, which shouldn't be a problem for matching custom eartips. The finish on the nozzle tips is a little rough, which is a bit of a bummer.

Sound Impressions
Measured with IEC 60318-4 (711) with 94dB(L)@500hz.
The sample used for the measurement does not represent the characteristics of the entire product.
Following Measurements are available at silicagel.squig.link

In many ways, the sound characteristics haven't changed much from its predecessor, the C3. Overall, the tone is fairly close to the Harman target, with a moderately rich, full-bodied bass and crisply drawn treble, which is a nice balance that works well with a wide range of genres.
As would be expected, the C3 MKII's bass impression varies quite a bit depending on listening volume: at lower volumes, the bass has more warm and lush characteristics than being analytical and dry, but as I cranked the volume up to a reasonable level, I could hear the bass gradually revealing more detail and transforming into a reasonably punchy and clear bass.
TinHiFi didn't specify the impedance and sensitivity of this product, but I personally felt that the C3 MKii required some power to drive. Despite the fact that my normal listening volume rarely exceeds 90dB, I had to push the volume up to around 60 levels with 3.5mm SE, high gain setting on the FiiO JM21.
I don't usually say this, but the 4.4mm balanced cables might be a great choice for C3 MKii.

As it follows the characteristics of the Harman Target relatively well, the midrange sounded quite decent.
Vocals are presented with a just right amount of body and distance. It's hard to detect any masking of the mid-range at moderate volumes, and you can even feel a slight sparkle from a voice.
Compared to some of the 'meta-tuned' IEMs that have been proposed in recent days, some may find the treble a little brighter. However, I rarely found the treble to be shouty or sibilant, but rather crisp and clear in most genres. If you're into a slight V-shaped sound signature, you'll enjoy this set.
The soundstage is also quite good. The rooms aren't very spacious, but the elements placed within them are quite detailed. The separation is quite good considering the price, as I was able to pinpoint the position of the various instruments immediately.

Conclusion

TinHiFi has been working with 1DD configurations for a while now, and I'm happy to say that the C3 MKIIs are a pretty solid product for $49.
A slightly V-shaped, Harman-style sound signature makes the C3 MKii an 'all-rounder', suitable for any genre of music.
Add to that the fact that the C3 MKII is positioned at a price point that anyone can afford, and with a design that's tiny enough to be used by those with small ears, I think the C3 MKII has all the charms to become a solid entry-level unit that I can recommend to anyone.
If I had to nitpick, I'd say the standard ear tips were a little disappointing, but I don't think that's too much of an issue in an age where you can get decent quality ear tips for cheap.
All in all, if you're looking for an affordable, all-round entry-level IEM with decent features and a comfortable design, I can easily recommend the TinHifi C3 MKII.

Review of TinHifi C3 MkII:


TinHifi C3 MkII is a new single-dynamic driver IEM from TinHifi. It is an updated version of the OG C3, originally released in 2022. The new model was announced on January 6, 2024, and immediately went on sale for $49.
For those unfamiliar with TinHifi, it is a Chi-Fi brand that started in 2017 and has since released many budget IEMs. Some of its most well-known models include the T3 Plus, the predecessor C3, and the planar one P1 Max. TinHifi aims to create affordable IEMs with a versatile and pleasant sound signature, making them suitable for a wide audience. Today, it is a competitive company in the Chi-Fi market, offering a variety of audio products—from cables to full-sized headphones.
Let's get back to the C3 Mark II. TinHifi C3 MkII features a single 10mm dynamic driver with an LCP diaphragm and an N52 neodymium magnet to help reduce distortion. While such a driver is common in many IEMs, the key factor is how TinHifi’s engineers tuned them. The C3 MkII also has an updated design, a new cable, and a convenient carrying case, which I will cover in this review.
TinHifi C3 MkII comes in three versions: Standard Edition with 3.5 mm cable, DSP Edition with Type-C cable and Upgraded version. For this review, I have the standard version with a 3.5mm cable.
Well, let's get started
Hello, and thanks for taking the time to read my review. I really appreciate it!
I’m Vlad, a former semi-pro FPS player, mainly in CS:GO, and now an audiophile and reviewer of audio devices.
My passion for music started with a classic Japanese Panasonic boombox. Later, I got my first headphones - Koss Porta Pro, which I absolutely loved. I spent years listening to music on those and the Sennheiser CX200. Back then, my playlists were filled with Linkin Park, DMX, Dr. Dre, and Eminem. Hip-hop and rap captivated me, especially the deep, rumbling bass and the distinct rap-style delivery.
Now, I consider myself a music enthusiast who enjoys a wide range of genres, from metal to classical music, choosing what to listen to based purely on my mood.
When it comes to sound, I prefer a neutral-warm V-shaped tuning. I appreciate a rumbling, well-defined bass and would consider myself more of a basshead than a treblehead. In the midrange, I have a particular fondness for male vocals, as I find them the most engaging and essential in modern music. What do I dislike? Harsh treble, a lack of bass, and a narrow soundstage.

The TinHifi C3 MkII comes in a small white box with a minimalist design. The front side features the model name with a small TinHifi logo on top, while the back side has an illustration of the dynamic driver structure along with manufacturer details.
Surprisingly, TinHifi did not include any technical specifications on the packaging. Perhaps I got a pre-release unit, and they might add this information later.
Inside the box, there is a large carrying case, nearly the same size as the packaging itself. Upon opening it, I found several labeled pouches: one containing the IEMs and cable and another with ear tips and meshes. Additionally, inside the case were a warranty card and a TinHifi brand card.
Back to the case, this is one of the most spacious and convenient cases I’ve ever used. It is made of durable fabric and features two compartments separated by an elastic band, allowing you to store multiple IEMs along with portable DACs.
I appreciate the attention to detail from TinHifi, especially this well-designed carrying case. I will definitely be using it for transporting my IEMs in the future.




The TinHifi C3 MkII shells are made of resin using 3D printing technology. The resin is completely dark and glossy, making the internal dynamic drivers invisible.
The design of these IEMs is, I would say, calm, pleasant and recognizable, for the company TinHiFi. The faceplate features a night sky with a few stars, symbolizing infinity, which each listener can interpret in their own way. There is also a large and distinct TinHifi logo on the faceplate.
For me, infinity is an endless journey into the musical world, getting emotional from the sound, and searching for something new and exciting in such a diverse world.
On the inner part of the shell there is a rather wide, but not long nozzle with a metal mesh inside and a damper, which can be easily removed and replaced by the included mesh. There is also an indication of the R/L sides.
On the side of the shell there is a small compensation hole and a recessed 2 pin connector.


The TinHifi C3 MkII shells are small and quite lightweight, weighing only 4 grams each. Their shape resembles a bean and is identical to the C3 or T3 Plus. This is an ergonomic shape that perfectly follows the shape of the ear and fits perfectly, providing a deep and secure fit.
Thanks to their anatomical shape, these IEMs fit perfectly in my ears and remain comfortable even during long listening sessions. The fit is very secure and deep, so they won’t fall out, even while walking or running.
I would say this shape is universal, making it suitable for most people, regardless of ear size or ear canal width.
As for sound isolation, this set isolates about 70-90% of external sounds. Yes, there really is decent sound isolation here, thanks to the closed shell shape , the short nozzle, the tight and deep fit and the small compensation hole.
I can confidently say that background noise won’t distract you, whether you're in a noisy room or on public transport.




The included cable is one of the strong points of these IEMs. It features a two-core braided design, made from oxygen-free copper and coated with a layer of PVC to protect it from external damage. The cable is extremely thin, lightweight, and quite flexible, with a slight memory effect. Additionally, it has beautiful metal fittings with a logo engraving. The total length of the cable is 1.2 meters.
At one end is a gold-plated 3.5mm plug, housed in a robust casing to prevent bending and damage. In the middle, you’ll find a metal splitter with the TinHifi logo, while on the other end, there are ear hooks with 0.78mm 2-pin metal connectors.
Quick reminder, you can also purchase the TinHifi C3 MkII with a Type-C cable and a built-in DAC.




The included ear tips are completely standard, similar to those found in most IEMs, including other TinHifi models. They are made from dense and firm gray silicone, which may cause slight discomfort in the ear canal due to its material.
The TinHifi C3 MkII comes with a generous selection of these ear tips in three sizes: two pairs of size S, two pairs of size M, two pairs of size L
The ear tips have a standard bore, meaning they do not alter the sound in any way. With them, the sound remains exactly as it was tuned from the factory.
Personally, I used similar ear tips from SpinFit, as they offer better material quality, although they are functionally and visually almost identical.


It’s difficult to determine how power-hungry these IEMs are, as we don’t have official information on their impedance and sensitivity. However, I’ll try to share my thoughts on their pairing with different sources.
While testing the TinHifi C3 MkII, I connected them to various sources, from an Android smartphone to a full-size DAC, gradually increasing the power output and I didn’t notice any significant difference in sound, apart from a slight variation in volume.
This is due to the fact that these IEMs use a standard dynamic driver, which doesn’t require much power to work properly.

The TinHifi C3 MkII has a neutral-warm, naturally V-shaped sound signature, with a slight boost on the lower range, a dip in the mids, and a rise in the upper mids. At times, they can sound slightly dark.
Imagine sitting in a small room, with drums playing in front of you, keyboards and strings positioned slightly further back, and cymbals and violins behind them, while you sing in the middle - that’s how the TinHifi C3 MkII presents its sound. But let’s break their sound profile down in more detail.


Sub-Bass: The sub-bass delivers a fast, energetic punch that is felt through a bassy rumble. It is audible and distinct at the beginning of each bass attack, with good separation, smooth rise, and quick decay, adding weight and body to the bass.
Mid-Bass: The mid-bass is boomy, deep, fast, and dense, with good resolution. It is very smooth, unfolding gradually and decaying slowly.
A great example to describe the bass performance is the track “Dancin” (KRONO Remix) by Aaron Smith.
I wouldn’t call these basshead IEMs, as bass quality takes precedence over quantity. The bass guitar sounds energetic, the drums add depth to the sound, and the drum kit with MIDI controller blends seamlessly into the EDM genre, making the sound fuller and weightier.
I found these IEMs particularly enjoyable for rock, EDM, hip-hop, and other similar genres.


Lower Mids: The lower mids in the TinHifi C3 MkII sounds warm and full-bodied, with a slight melodic and bassy touch. However, it depends on the song you're listening to.
To experience the warm, melodic lower mids, I used "The Lazy Song" by Bruno Mars, while for a more bassy feel, "Just The Way You Are" by the same artist worked well.
Instruments in this range sound full-bodied and pleasantly warm, without distortion, while the vocals feel delicate, layering over the instrumentals like a feather.
Overall, the lower mids act as a bridge between the bass and mids.
Mids: As a fan of warm tuning, I really enjoy how the mids sound in the C3 MkII. They deliver exactly what you’d expect at this price point, or maybe even more.
It’s clear that TinHifi’s engineers put effort into tuning the mids, making them melodic, tonally rich, and airy. I can confidently say that this tuning will appeal to most listeners and it’s probably the best mids among TinHiFi’s dynamic driver models.
To describe the mids, I chose two warm-sounding tracks: "All of Me" by John Legend and "Only Love" by Ben Howard. These tracks perfectly highlight both vocals and instruments.
Almost all instruments in this range sound realistic and warm: The guitar timbre is natural, piano notes are melodious, and the violin has a slightly dark tonality
Male vocals sound like they are wrapped in a warm blanket. Tonally rich, warm, and pleasant to the ear, but not always the most accurate.
With these IEMs, I enjoy listening to artists like Ed Sheeran, Pharrell Williams, Bruno Mars, and Lewis Capaldi. However, they are not ideal for deep-voiced singers like Louis Armstrong, Frank Sinatra, or Elvis Presley, as their lower vocal register is not quite suited to such a setup.
Female vocals sound sparkling, slightly bright, and sharp. Similar to male vocals, this tuning works well with warm-sounding female voices, such as Britney Spears or Carly Rae Jepsen. However, it struggles with operatic voices like Ella Fitzgerald. A track like "Summertime" may sound unnatural and unconvincing on this set.
Upper mids: This range feels elevated and energetic, adding a quintessential liveliness to the sound. I wouldn't say that there's an excessive amount of upper mids, they don’t cause fatigue, but rather add a unique charm to the music, like a cherry on top.
This is particularly noticeable in high-pitched vocalists, such as: "Happy" by Pharrell Williams and "Someone You Loved" by Lewis Capaldi
You can clearly hear a slight darkness in the overall tonality, which is a characteristic of this model. However, despite this darker tone, there is a generous amount of upper mids in the mix.




Treble: The treble is sparkling, moderately bright, and clean, with a slight darkening as they decay.
To describe the treble, I chose two songs: "Chandelier" by Sia. This track perfectly highlights female vocals, which sound slightly bright but clean, without breaking apart at the end. "Starboy" by The Weeknd, here, you can hear male high vocals blending smoothly with the instruments, without noticeable sibilance or graininess.
The treble is not dominant, I would even say they lean slightly dark. However, for my ears, this tuning is just right.



To feel the instrument separation and soundstage, I used "Chop Suey!" by System Of A Down.
The soundstage here is wide and spacious but not particularly tall. I would describe it as a medium-sized room where all the instruments are positioned in their own spaces.
In terms of instrument separation, there are no problems, each instrument and vocal line is distinctly audible and well-isolated from the rest of the mix. Because every instrument occupies its own space, the imaging is accurate, making it easy for me to determine the direction each sound is coming from.



- TinHiFi C3 MkII vs Kefine Klean (49$):
The first comparison I’d like to make is with the single DD - Kefine Klean
The Klean is made of metal and features a removable nozzle, allowing for a more customizable sound signature, while the C3 MkII is made of resin and comes with extra meshes in the package. Both pairs offer a comfortable fit and provide similar levels of soundisolation.
When it comes to sound, these two models have different approaches to tuning.
The Klean follows a U-shaped tuning, providing a more balanced sound across all frequencies..
On the other hand, the C3 MkII is a natural V-shaped IEM, with a slight dip in the midrange.
Bass is fairly similar in both, though the C3 MkII might have deeper sounding bass.
Mids in the Kefine Klean sound melodic, accurate and well-defined, while in the C3 MkII, they are smoother and warmer, slightly recessed.
Treble in the Klean is brighter, more sparkling, and airier, while in the C3 MkII, it is warmer, slightly darker, but still pleasing to the ear.
Soundstage in the Klean varies depending on the source but is more spacious, deeper, wider, and taller than in the C3 MkII.
In summary, both are dynamic driver IEMs, but the Kefine Klean offers a more melodic, accurate, reference-like tuning, while the C3 MkII delivers a more fun and warm sound signature.
- vs Kinera Celest IgniteX Beast (49$):
Next, I’d like to compare it with the Kinera Celest IgniteX Beast:
Both models are made of resin, have a similar ergonomic shape and fit, and offer a decent soundisolation.
In terms of sound, the IgniteX Beast feels tighter and has a noticeable metallic timbre, especially in the midrange and treble.
Bass is similar in both quantity and quality across both models.
Mids in the C3 MkII sound more natural and pleasant, while in the IgniteX Beast, they exhibit a noticeable BA timbre, which some listeners might not prefer.
Treble in the IgniteX Beast may feel overly bright, while in the C3 MkII, they are warmer and darker in comparison.
Overall, I would only recommend the Kinera Celest IgniteX Beast if you specifically enjoy a BA sound signature. In most other cases, the TinHiFi C3 MkII would be the better choice.


The TinHiFi C3 MkII is a versatile choice for a wide range of listeners, whether you're a casual listener or an audiophile. They offer everything a typical listener needs, from a high-quality stock cable to a well-balanced tuning.
I believe TinHiFi has addressed the shortcomings of its predecessor's dynamic driver model. The new tuning is warmer and less bright, featuring: Deep and impactful bass, warm mids with a pleasant vocal presentation, a slight emphasis on the upper mids, sparkling and slightly bright treble, a spacious soundstage with precise imaging and separation. And all of this comes at an affordable $49 price tag.
I'm confident that this is a worthy upgrade over the original C3 and perhaps the best dynamic driver IEM from TinHiFi to date.
