Tinhifi C2

Summary: Unfortunately I am way too late for this review, but thought to do it anyway as it seems to go on sale on a lot of local places. This has decent build and looks, comfort is slightly lacking. In terms of sound this has a bright mild v shape sound signature. Overall at sound is ok but not good enough for its asking price.

Sound signature: bright, mild V shape



Overview:
This is a single DD iem with 10mm dynamic driver with an impedance of 32ohms and sensitivity of 104db.
Talking about Tin hifi, they are one of the moe popular chifi brands. One of their most popular model the tin hifi t2 started my journey with tin hifi. Other than the t2 and p1 I personally did not find their other releases that special.

Box and accessories
In the box it comes with:
Iems itself
2 pin cable, its average price considered. They have provided better cables with their other offerings.
3pairs of narrow boar tips (average quality)
3pairs of medium boar tips (average quality)
Papers



Build and Fit:
Build in general is good price considered. It’s made of cnc machined aluminum, feels decent in the hands. In terms of looks, they are one of the best in this price range, it has a industrial sci fi look. Shells are medium to small size. They are decent weight as its fully metal built. Fit is good but it does sacrifice in the comfort region. Fit stability and breathability is ok. Score 3/5

Sound
Bass
Bass performance is ok. Sub bass is more forward than mid bass with good rumble and attack. But mid bass is not as prominent and its lacking punch and slam. Bass notes are separated and bass texture is ok Speed is ok for a dynamic driver. Personally I would have prefered more mid bass extension. Score 2.5/5

Midrange
Coming to the midrange, as a whole its ok. Transition from mid bass to lower mids is linear. Vocals are crisp and clean but specifically female vocals sound a bit thin. There are some peaks which is audible but not sinilent. Instruments are also clean and linear sounding but in certain tracks it is brighter due to the peaks as mentioned. Personally I would have preferred a bit more body and thickness in the overall mids. Score 3/5

Treble
Talking about treble performance, it is energetic and bright. Details are crisp and have good shimmer to it. It has decent resolving capabilities. I would say this sound very analytical.
Unfortunately there is a fair bit of sharpness/ harshness present in a lot of tracks, so this will not be suitable for treble sensitive listeners. Although I enjoyed its treble with metal and rock music. Score 3.5/5

Technical performance (score: 4/5)
Soundstage: above average
Imaging: ok
Sound separation: ok
Dynamics: ok
Resolution:good



Conclusion
I personally do not recommend this set, as there are better options in its price range and even in its discounted price range. Other than that this is more suitable for genres like metal, rock and classical in my opinion.

Introduction

Following the descending order of review, it is now the turn of the TiHiFi C2. This is an IEMS made of 6063 aviation grade aluminium, which has a 10mm dynamic driver, with a PU+LCP (Liquid-Crystral Polymer) composite diaphragm. It uses a Daikku CCAW 0.035mm voice coil and an N52 neodymium magnet. It is clear that its metallic design is reminiscent of many other metallic IEMS with screws. But TinHiFi wanted to introduce a story behind it: the C2 is a mechanical warrior who wants to safeguard peace. It is not for nothing that the nickname of these IEMS is MECH WARRIOR.
Finally, it is worth noting that this is one of the cheapest IEMS TinHiFi currently has for sale, priced at around €25 at the time of writing this review. Let's see what TinHiFi is capable of in this price range.

• Driver Type: 10mm dynamic driver with PU+LCP composite diaphragm, Daikku CCAW 0.035mm voice coil and N52 neodymium magnet.
• Frequency Response: 10Hz-20kHz.
• Sensitivity: 104±3dB @ 1kHz 0.179V.
• Impedance: 32 Ω ± 15%.
• Power rating: 3mW
• Maximum distortion: 3% @ 1kHz 0.179V
• Jack Connector: 3.5mm SE gold plated.
• Capsule Connection Type: 2Pin 0.78mm gold plated.

Packaging

The TinHiFi C2 comes in a classic small white box with dimensions 101x101x33mm. On the main side there is a line drawing of a mechanical warrior. It is clear that this is the C2. At the top left is the logo of the brand and in the centre right is the name of the model. The back face is the same as other models: the logo, where it was manufactured, 3 QR codes and another barcode, along with several other logos of the certifications it meets. Repeating the formula, inside are a couple of cards, while the IEMS are inside a light grey foam mould. Underneath is a small white cardboard box containing the rest of the accessories. This is the complete contents:

• The two C2 capsules.
• One cable.
• Three pairs of black silicone tips, narrow core, sizes SxMxL.
• Three pairs of black silicone tips, medium core, sizes SxMxL.
• One warranty card.
• One certificate of authenticity.

The cable is not as bad as you might expect. It's fortunate that it's not the black 4-wire cable that comes in many IEMS in this price range. Without being the best, it's passable. As usual with TinHiFi, there is no bag or carrying case.



Construction and Design

We could all rattle off a list of IEMS that bear a resemblance to the metal design of the C2, but I'll skip this step. It is a metal design, manufactured from 6063 aviation grade aluminium by a high-precision 5-axis CNC. Its shape combines profiled, flat faces, with slightly rounded edges. The outer face is flat, with three Allen screws and a Y-shaped opening, through which a grille can be seen. Most of the edge faces are flat profiles, except for the edge near the mouthpiece, which is rounded to improve ergonomics. The 2PIN 0.78mm connection is on a transparent plastic plate, inside the body of the capsule. It is not surface mount, so a compatible connection is required. The inner side has several planes. The first and lowest one is rounded. The second is flat and has the letters R and L inscribed on it. The third is the first cone of the nozzle and has a hole. On the last one is mounted the mouthpiece, which is made of a more polished and shiny metallic material. The first part is a cone, followed by a cylinder with a smaller diameter of 5mm and the rim of the nozzle, with a diameter of 5.75mm. The grille is made of metal and is perforated with small holes. The construction is perfect and exemplary and the weight is surprisingly low.
The cable is fairly basic, with an angled, gold-plated, 3.5mm plug. On the outside of the metal cylinder is the brand logo. It has a velcro strap. The cable is made of two strands of transparent PVC coated wire, joined together. The splitter piece has a narrow trapezoidal shape and is made of black plastic. The cable has semi-rigid ear guides. The 2Pin 0.78mm connectors are mounted on classic black rectangular pieces that are narrower in the pin area. They have the letters R and L embossed on them and a blue dot to indicate polarity. As I say, the cable is pretty basic, but I don't find it as bad as others in its range. What can be a bit annoying is that the coating can give it a certain stiffness and undesirable memory effect.



Adjustment and Ergonomics

The metal construction could indicate that these are heavy IEMS. The shape with many profiles, edges and edges, that the capsules are uncomfortable. But neither one thing nor the other. They are quite light, of course not as light as other resin constructions, but their weight is not relevant. The ergonomics are quite good. Only, as the hours go by, I have noticed some discomfort. The texture of the metal is micro rough and pleasant. So many edges and edges do not bother you as you would expect. The mouthpieces are well projected and have a good angle to face the ear canal. In addition, they are of a length that allows a medium insertion. However, the diameter of the nozzle may limit the depth of insertion. However, the fit is simple and durable, does not allow rotation and fits securely. They are suitable for testing with a multitude of tips, as long as they are of the relevant inner diameter. With foam-filled silicone tips, a fairly high level of insulation is achieved. Quite good.



Sound

Profile

The TinHiFi C2s are another twist on the FR cocktail that is the brand's latest saga of models around a success curve. Despite being the cheapest, the C2 seems to be the model with the most emphasis on treble, if only in view of its graphics. If the T2 DLCs are the most balanced, the C3s the most V-shaped and fun, the C2s are the little brothers of the T4 Plus, but with a bit more fun, to be more attractive in such a wild price range. And, alternatively, the C2s offer another little surprise in their design, that little Y-shaped vent on the outer face of each capsule, something that adds a little more openness to their sound and a more airy and credible bass reproduction.



Bass

Back to the mid-bass. I would hazard a guess that those who don't like bass prefer more pronounced U-tunings than the current one, which achieve a more extreme and complex to reproduce lower region elevation, as well as a cleaner midrange. It certainly works and is a successful way of adding spice for audiophiles and amateurs who are choking on bass. Gentlemen, there is bass here, and in spades. The mid-bass is here to stay and to hit the eardrums, but mercifully. These IEMS are not just for bass heads, they are fun IEMS. The good thing is that the dynamic drivers are getting better and better and there is more control in the area. Thus, the punch is noticeable, dark, slightly thick and subtly invasive, one of those that leave a bit of aftertaste in the atmosphere. Indeed, heavy for some people, sweet for others. Its texture is clear, rough and descriptive. In the pure tone test it defends itself with naturalness and presence, with that dark colour I mentioned and a quite realistic sonority, although with a slight excess of rumble. In the reproduction of complex phases it imposes authority and has the ability not to drown the voices in a dark and magmatic bass well. And its level of darkness helps in this regard, because it serves to make the differences more apparent. On the one hand, there is a deep, black, but localised bass focus. On the other hand, the focus of the vocals is not in the same spot, but manages to be defined and distanced effectively and naturally. This is where the difference between good bass lies, in the relationship between control and respect. It is clear that he is not a technical prodigy when it comes to constructing structured lines and bases with the best resolution. But it has enough definition for the layers to draw a realistic melody and not just offer a bloated mass of unpolished bass. Although, admittedly, that mass may be too much for some.



Mids

The slightly dark and thick character brings warmth to the midrange. But, fortunately, an undesirable muddy feeling is avoided. There is a difference in the level of the male and female voices. The former are a little more distant, they are also denser, softer and velvety, which makes for greater musicality, but a retreat in the level of detail and complexity, when it comes to their portrayal. It is a simpler, more pleasing staging, but without an overly neat or brilliant technical execution. In this sense, the circle is closed by returning to the dark thickness, inherited from the lower range, in this first half of the middle range, something that is contagious to all the instrumentation of this phase. This is how one observes a slightly biased ambience in the brightness, subtly lacking in harmonic information, in its resolute development, which can produce a slightly dull and low liveliness representation. On the other hand, the female voices take a step forward in presence, although they are still infected by that cohesive musicality which prevents them from being freer, cleaner, neater and more transparent. Well, this can be called warmth, but also mixed with a slightly sterile dryness.
If we talk about technical qualities, the C2 presents a certain ambivalence. At first, it might seem rather plain in these respects, lacking a clean and clearly discernible background, as well as that wide bass that can flood the scene at times. However, the level of detail manages to overcome this and stands up quite well for its price range. I think it benefits from the sense of air and openness provided by the Y-slot on the outer faces of the capsules. In this aspect, in conjunction with the more than remarkable treble extension, it can sometimes even seem analytical. But, always within parameters that are kind enough to coin this term.



Treble

From the graph, it might seem that the treble is in extra favour, within the group of TinHiFi IEMS that I have reviewed lately. But, in fact, this is not the case. The high range is in the common line of the rest of these models. They have extension, but limited projection. On this occasion, the bass counterbalance detracts from its prominence and clarity. The tuning is a little uneven here, with some more pronounced peaks, something that raises a false sense of emphasis on some details and high notes, which can sound a little forced. In an overall complex expression of the treble, the high notes can be more unevenly represented, losing the more accurate control and refinement of their siblings. This is how some tones sound more natural and controlled, others a little more mismatched. Fortunately, this is not a sibilant ensemble and both control and tuning work in its favour in this respect. Finally, there is a good amount of air for the price point, something that helps to enhance the soundstage.



Soundstage, Separation

The amount of bass can be a vehicle that enhances the scene, or compresses it. At times, the scene feels deep, more physical and grand. At other times, it can feel more compact, tucked in and oppressive, crowding in detail and preventing expansion. There is good frontal projection and acceptable laterality. The stereo feel is clear and perspicuous.
As I have been repeating, there is a flattering sense of openness and air, bringing a little gas, separation and vaporousness to the ambience, helping to dilute the music. But, conversely, the cohesion derived from the darkness and warmth, fights against it. But overall, the sound has a more than reasonable separation, even remarkable for the price, something that adds extra value to the whole.
In terms of imaging and instrumental positioning, the peculiarly analytical character helps in this respect, being effective on most occasions. However, it is important to be clear about the range in which we find ourselves, when it comes to valuing this feature.



Conclusion

It is true that, lately, my ears are being fed with honeys of other, higher prices. But I can't hide my predilection for these IEMS. The TinHiFi C2s deliver everything I'd ask for under $30: stellar construction to stand up to daily treatment for a long time; a powerful sound signature, with punchy bass, but not forgetting the mids or the highs; a dash of analytical profile to bring to the fore those details that, in theory, only higher-priced IEMS can reveal; ergonomics and comfort that are not at odds with durable, metal construction. The only thing it lacks is a better cable and a carrying case. But all that can be easily fixed. However, to offer as much as these IEMS for this price is much more difficult. All in all, the C2s are a safe bet for those who like a more physical and punchy musical feel in the low end, mixed with the smoothness and control of the rest of the range, while maintaining an overall musicality and a good degree of descriptiveness.

INTRODUCTION:

The TIN HiFi C2 is dubbed as the “Mech Warrior” owing to their sturdy construction and mechanical appearance. The tagline is reminiscent of a childhood dream, where one envisions oneself as a guardian of peace, fighting tirelessly without ever surrendering.



The tagline initially left me somewhat bewildered. While I can envision a scenario of a child utilizing the C2 as a means of communication while piloting a mech warrior, I cannot connect the dots between the concept and the C2. I am left wondering if the C2 conveys a playful or authoritative sound.
While such phrases may appear more fitting for a toy packaging, they do hold a certain relevance. The TIN HiFi C2, with its dependable build and sprightly sound signature, invokes a sense of reliability and determination, as if they were a loyal companion in one’s musical journey.

The C2 boasts a refined sound quality for its price point. The C2 can produce a dynamic and energetic sound presentation, demonstrating its impressive auditory capabilities.

Put on your helmet HUD, and join me as we embark on this mission to discover the truth about the C2.

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:​

Configuration: 1 x LCP (liquid crystal polymer) + PU composite diaphragm
Impedance: 32ohms
Sensitivity: 104dB (@1kHz)
Freq response: 10hz - 20khz

PACKAGING:​

The C2 are packaged in a compact, unassuming white box that comfortably fits in the palm of one’s hand. The front features a monochrome illustration of a mechanical warrior, reminiscent of the popular Japanese anime series Gundam.



Meanwhile, the right side of the box lists the technical specifications in both English and Chinese languages. The left side is adorned with TINHiFi’s logo, while the back of the box displays QR codes for their social media accounts alongside a Chinese motto that roughly translates to “Every day is a new beginning.”

The box’s minimalist design is standard, lacking any flashy or vibrant hues that would otherwise detract from the product’s understated elegance.

In the box​

• TIN HiFi C2 IEMs
• Cable
• 3 pcs medium bore silicon ear tips (S)
• 5 pcs medium bore silicon ear tips (M)
• 4 pcs medium bore silicon ear tips (L)
• Product warranty card
• TIN HiFi card

Inclusions are barebones and are what is expected in this price range. No complaints here on my end.

The ear tips all seem to have the same bore size - no matter how I squint at them. Not much of a choice, really. But don’t worry, just pick the size that fits your ears best and gives you the perfect seal.


The S-sized ear tips were used for this review.

SOUND IMPRESSIONS:​

Tests were done with Ovidius B1, Hiby RS2 DAP, Centrance Dacport HD, Oppo A94 smartphone, and Hidizs AP80 pro DAP using FLAC, WAV, and DSD files. The streaming services used were Apple Music, Tidal, and Qobuz; mobile apps were UAPP and Hiby Music.

The C2 has an engaging,vibrant and energetic sound that is very easy to admire. They will not just cater to seasoned audiophiles or musicians but also to the average consumer.

What really surprises me is the refinement of the sound quality. A few years ago, the typical sound of sub-USD$50 IEMs was a dominant bass response that slams really hard, then the rest of the frequencies were either too recessed or veiled sounding due to too much emphasis in the low frequencies.

Although the C2 bear the usual U-shape sound signature, I can’t shake off the fact that they have good control over the whole frequency spectrum.

The tone and timbre are reasonably sensible and depict how things actually sound - closer to real life. Nothing really jumps out of its place, whether it’s jazz, reggae, funk, rock, or even orchestral tracks - all sound excellent, and exciting.

In the facets of technical performance, as we expect at this price point, there are shortcomings, including a linear soundstage. Almost everything is pointed toward the center. Imaging or placement of instruments is audibly present, but nothing remarkable to note.

On the flip side, the speed of the drivers are rather fairly acceptable as they are not insanely quick nor sluggish, and they exhibit an appropriate and consistent performance. There might be ineffectiveness when it comes to complex tracks, nonetheless, they perform decently.

Resolution is below average as the C2 doesn’t have that proper sense of individuality in instruments. The presentation is in one place rather than systematically arranged within the soundstage. Note definition doesn’t have an overly edgy presentation despite possessing quick attacks.

The C2 is fairly easy to drive, and proper loudness can be achieved even with a modest smartphone.

Bass​

The bass of the C2 is mature and controlled, delivering a refined listening experience that is not aimed at bass heads. The Chain by Fleetwood Mac intro of drum kicks has a decent punch and nice attack, showcasing the bass’s tasteful balance.

Bass guitars are never boomy or overbearing, with a good touch of mid-bass definition. The overall sound signature exudes a sense of restraint, making it a suitable choice for those seeking a more refined and discerning listening experience.

Bass bleed is almost non-existent, providing clean and nicely defined bass even for modern tracks. Although my playlist consists mostly of classic tracks (Stevie Wonder, Alan Parsons Project, George Benson, Bob James, Lynyrd Skynyrd, AC/DC, Michael Jackson, EWF, and the likes), even modern music like Daft Punk and Calvin Harris never sounds boomy or smeared. This showcases the C2’s ability to deliver a balanced and clean sound that is not overpowering, making it suitable for a wide range of music genres.

Midrange​

I find the midrange slightly recessed in the general presentation across its frequency range. Typically, this kind of presentation really turns me away, but surprisingly, it still does deliver the representation of instruments I’m quite fond of like pianos, Rhodes piano, organs, brasses, snares, mid toms, percussions, tenor sax, cellos, horns, and some synths are very bright, transparent, and have good presence. The recessed nature only occasionally comes into play, with some vocals sitting behind the bass domain.

The upper mids are never shouty nor hot, even in brightly mixed tracks. Vocals are equally proper in sound, both male and female.

Treble​

The treble on the C2 is neither aggressive nor lacking in air and openness. Among all the frequencies, the treble is the star of the show, offering impressive detail and crispiness.

Moreover, it does not exhibit any sibilance, which makes it safe for people with sensitive ears. The cymbal strikes are sparkly and have an average bite, allowing unmasked sound reproduction. The energy of the C2 gives it a lively and vivid sound signature, which is bound to impress even the most discerning audiophiles.

COMFORT and FIT:​

Comfort is subjective because we all have different ear anatomy. Small ears may experience some discomfort during long listening periods due to the C2’s sharp edges. I personally experience this on the antihelix part of my ears at around a 2-hour mark of continuous wear.

If you have a habit of sleeping or napping with IEMs on, the C2s might give you soreness over time. Nonetheless, I anticipate the opposite for large ears.

COMPARISONS:​

As part of my assessment, I will compare the C2 and Dunu Titan S, a model that I currently have on hand with a similar driver type and price range.

Vs Dunu Titan S​

The Dunu Titan S boast a more refined and polished signature, with the treble in particular exhibiting greater restraint and control. The tonality is somewhat smoother and more detailed, offering a neutral listening experience that outshines the C2.

While both IEMs perform comparably in the low-frequency range, the Titan S midrange takes the lead, delivering a forward sound that accentuates the nuances of each instrument. Overall, the Titan S proves to be a worthy contender in about the same price range, packing a more polished and sophisticated sound.

The soundstage is prominently wider on the Titan S, and instruments are better placed and accurate. Details are more audible and felt, coming off as a better player in technicalities.

Ear insertion is a tad bit deeper with Titan S with less pinna gain.

Ultimately the Titan S are more subtle and less energetic, with better technicalities. The C2 are vivid and brighter in sound and more prone to listening fatigue in the long run.

And many more… I always listen to High resolution format, being the least quality 16bit/44khz FLACS be it offline or online.

VERDICT:​

Truth be told, it scares me how well the IEM budget segment is coping with competition. The gap continues to narrow between entry-level and mid-range players. While the C2 are not giant killers, they sound not far off of gear priced around the USD$100 domain.

The C2’s tonal accuracy is noteworthy and can easily win over those who prefer brighter sound signatures. Casual listeners will likely be smitten with the sound profile right from the start, except for those who crave serious bass. However, audiophiles and discerning listeners will find themselves yearning for more technical finesse.

Despite their unremarkable technicalities, the C2 remain highly appealing and deserving of praise. Their fun and lively sound exudes the essence of being a “mech warrior” - adventurous, nimble, and ready for a battle.

I would like to thank the folks from HiFiGO for sending this unit in exchange for this review.

TinHifi C2: Sanded Down Shine


|| Introduction ||

TinHifi is no stranger in the IEM market not only in the east but also in the western side of the world after the release of their popular Tin T2 IEM back in the day. Nowadays, TinHifi hasn't been in the limelight of IEMs after releasing products that didn’t quite make it big like their T2.

We will be looking at the Tinhifi C2, the smaller of the two C-series IEMs released as of the writing of this review. Priced at around $30 and sporting a unique mechanical look and a well-known driver setup.

Tinhifi released their new line of IEMs named the C-series aiming at the price range where the T-series of IEMs were once and still revolve around. Will they once again capture the hearts and ears of the masses with this value oriented release?


|| Disclaimers ||

I don’t consider myself as an audiophile or an enthusiast, therefore the terminology and the overall review will be more mainstream.

• We prefer to keep our reviews simple without too much confusing lingo and terminologies.
  
  
• This review set is a part of a review tour and was sent free of charge in exchange for an honest review. There is no material or financial incentive for us to do this review. We guarantee no exchange has been done by both parties to influence or sway our opinions on this product.

• My thoughts and opinions are of my own. My experience will entirely differ from everybody else. The contents of this review should not be considered factual as this hobby heavily leans on subjectivity. YMMV.

| Packaging |

The C2 comes in a no-fuss compact white box with a mecha/robot illustration in the front and branding. There are also other branding surrounding the box and manufacturer information, but oddly enough no spec sheet or a manufacturer provided graph like most IEMs comes with.

(Not that it matters anyway)


| Unboxing & Accessories |

The unboxing is really straightforward and smooth. No unnecessary bells and whistles with bad execution, just clean one and done action. Once the box is opened you are greeted with some paperwork and immediately followed by the IEMs themselves surrounded by foam for protection. A separate box is present for the stock eartips (2 pairs of each standard size), and a non-braided, L-type, 0.78mm 2-pin cable with a 3.5mm termination and pre-formed earhooks.

I would like to note that I really like the stock cable similar to the one that comes with the SSR and SSP models from Moondrop. Just a simple, and minimal cable with no thick braids and has an L-type 3.5mm jack. Too bad there’s no chin slider for better adjustability.

Item Breakdown:

• TinHifi C2 Shells
• 2-pin Stock cable (non-braided, 0.78mm, L-type)
• 2 pairs of each S,M,L size eartips (12 tips in total)

| Build & Driver Configuration |

The drivers on these are said to be a “newly developed” 10mm dynamic LCP+PU driver unit. I’m not quite sure about the “PU” characteristics of a driver and what it can delivery but “new” innovations is always welcome, though LCP is quite a common driver in the budget range as of recently from popular sets such as the Moondrop Aria 2021, DUNU Titan S, and the TinHifi’s own Tin T3+

The C2 shells are made out of CNC'd 6063 aviation-grade aluminum that feels light but robust and sturdy in the hand. This is one the best feeling IEMs I’ve tried in this budget segment and is definitely a positive for me.

Each shell has a Y-shaped vent in the main faceplate and a small circular vent right under the nozzle area. The main faceplate also has 3 allen nuts that is most probably for the looks than a functioning feature (or maybe a way to holding the main faceplate to the rest of the shell instead of plastic tabs or glue).

Engravings are present towards the inner part of the shell to indicate the left and right drivers.
There are no wings on this shell design which is a huge thing for people like me who particularly find them uncomfortable and the nozzle having a nice length protruding from the body for better insertion depth.

I would like to note that the 2-pin slots are quite recessed(or one can say encased) so there may be a potential incompatibility issue with other cables that don't have a protruding pin.

Overall the drivers are shaped with sharp chamfered corners and less curves to better insinuate the industrial/mechanical look.

| Isolation |

This isolates really well as with almost any type of IEM out there, so no qualms here.

| Comfort |

This stays comfy in my ear for long hours without having too much fatigue especially with the absence of a wing. The somewhat sharp looking design doesn’t impede on comfort as per my experience with it. The occlusion effect on this one is good that it doesn't have it as bad as other IEMs, probably because of the Y-shaped vent pointing outward similar to the BQEYZ Topaz I’ve reviewed recently.
** I used the stock cable included with Sony EP-EX11 eartips(small) through the Zishan U1 **

|| Sound ||

The overall sound is a mild U-shape in my ears with ample rumble that doesn't impede other frequencies and a forward but slightly grainy treble. The C2 sound natural with no weird quirks to the playback.


| Drivability |

I find these to be very efficient and don't require much power to run properly. Better and more powerful sources are still advised by be careful with the noise floor on IEMs.


| Bass |

The bass is good, speedy, and with enough “oomph” and punch to satisfy me in my experience. Light rumble can be heard/felt for the sub-bass performance with minimal to no bleed at all. Texture and grit could be improved too as well.

Some may find this too lean or too soft depending on one’s bass preference but this isn’t for bassheads.

| Mids |

Instruments sound great with enough air and texture but vocals can sound a tiny bit thin at times depending on the song. Male vocals in particular are less forward than their female counterparts. Speaking of female vocals, they’re rich and engaging which I enjoyed very much. Though still depending on the song and the artist, they can sound mildly shouty at times.

Overall the mids don't sound drowned or veiled despite being a U-shape set. It’s exciting and has energy despite not being as forward as the other two frequencies.

| Highs |

One of the highlights of this set, some may even call this somewhat bright but to my ears it’s just a tad bit treble forward from the pack without the harshness, peaking and fatigue. It extends pretty well, doesn’t feel cut-off/capped and has good detail retrieval.

Although this may be it’s highlight in my opinion, I have experienced it sounding coarse/grainy like what other people have reported to experience.

Despite being really sibilant sensitive, I find this set to handle sibilance pretty well. It doesn’t sound “ethereal” or anything of the same description but it’s still something special.
| Technicalities |

The C2 is a very competent set when it comes to the technicalities and I for one used it on other activities other than music listening and worked quite well.

Imaging is good, I can easily pin-point the origins of the sound pretty well with ease. Layering is decent without turning the playback into a mess. I feel the soundstage may be more wide than length but sounds boxy in some instances oddly enough as if I can the “shape” of the sound.

|| Conclusions ||

This is a really good set for its price point of $30. The TinHifi C2 is definitely one of the things I’ll recommend to people looking for a great set on a budget. Combined with a great build, decent accessories, and a well executed overall sound, what’s more to ask for something under $50 price range. There are clear shortcomings, but that doesn’t take away from what it delivers well.

Overall this set is a pretty enjoyable experience for me and for my friend who tried it and immediately contemplated buying it.

Review Of The Tin HiFi C2​

Introduction​

In the world of audiophiles, TinHiFi, a company that specialises in electroacoustic equipment, has a significant following. TinHiFi, a Chinese company, was founded in 2017. Since then, a variety of iems, from affordable to high tier, have been published. Tin HiFi has conducted research on the potential of a variety of drivers, from planar magnetic to dynamic drivers. Many audiophiles also commended one of their planar magnetic iems, the P1 Max, which I particularly loved. But up until this point, they had just the T-series of dynamic drivers, such as the T1, T3, T2 plus, etc. They have introduced the C2 and C3 series of new IEMs. In addition, I'll be discussing the TinHiFi C2 "Mech Warrior" today. But first, let's clear up a few things.

Disclaimer​

*Since this unit was sent by the generous people at Linsoul, 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, visit 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 "C2."
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the C2 based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

The C2 is an in-ear monitor (IEM) with a single dynamic driver; it features a 10mm dynamic driver with an LCP+ PU diaphragm, a N52 neodymium magnetic circuit, and a CCAW 0.035mm ultra light voice coil. The 6063 aluminum grade shells are processed using a 5-axis CNC high precision numerical control machine tool. Although these IEMs are lightweight, the shells resemble typical campfire audio IEMs almost exactly. The shells have a wonderful feel to them; they are sturdy and well-kept. The body is fastened into the faceplate using three screws. The single ended, L-shaped 3.5mm termination port on the detachable cable has a 2 pin connection. The cable feels average in quality, tangles easily, but does the job. 6 pairs of eartips are among the additional C2 accessories that are offered (small, medium and large). In terms of technical details, the sensitivity is 104dB and the impedance is 32 Ohms. With a maximum distortion of 3%, the frequency response ranges from 10Hz to 20kHz.

Sound​

The tuning of C2 tends toward a bright V-shape, and the tone is polished. The tone is slender, but it seems airy and open to me. The treble extension on the C2 is good, and the midrange is lively and clear. The bass has a powerful, lively, and inviting sound. To be completely honest, this is probably my preferred tuning, but I'll make an effort to be neutral for the remainder of the review. So let's explore the sound a little bit more.

Treble​

The treble area has a fantastic presentation that is light and airy and has a very expressive and richer sound. Overall, the sound is very airy and crisp, with a large amount of high treble that nonetheless seems to be missing. The male vocals also appear bigger and more expressive, but they also seem a touch more reserved than the female vocals, which reach out far and wide. The instruments sounds presentative and bright, the cymbal crashes or the snare strikes as well pops out and stretches pleasantly. As we approach the lower treble, the sound is bright and lively, almost lean, but it doesn't sound uncharacteristic or offensive, but it may feel on the verge of being sibilant or hot. Well, this is not a problem at all. This area's appeal lies in the way it nearly sounds open and dreamlike. When spoken out loud definitively, the entire treble region's presentation is favourable, sounding bright, airy, and open with lots of energy.

Mid Range​

The presentation is upright even though some may feel thin sounding, but it is more or less light variable existent. The mid range may appear pulled back yet sounds quite dynamic and alive. The upper midrange blends seamlessly with the lower treble and has a lively, forward sound with a decent stage. The vocals appear direct and sound rich, and the instruments also sound well-done and exciting. While it is still beautiful, there are sporadic flashes of metallic notes. The lower mid range is erect and progressing. The harmonies between the voice and the instruments are excellent; they don't sound flat or muddy. The lower mid range presentation is quite fluid and unambiguous. Although occasionally it may seem like the metallic essence emerges and affects you in a new way, I appreciate the tuning in this region, which complements the upper mid range with a strong body. To be more precise, the mid range's overall performance is anything but relaxed; rather, it is spirited and active.

Bass​

Impactful punches that resolve fast and with ease are used to control the bass extremely well. Although there is solid body presence that bleeds into the lower mid range, it doesn't severely impair the sound because the bass emphasis is more on the sub bass region than the mid bass region. The bassline sounds uncharacteristic; by this I mean that they sound too good and clear, when I think they should sound heavy and solid. I therefore anticipated the note to be hefty, dense, and smashing. Of course, that doesn't turn out badly. Although the sub bass has good length, I believe it should have a more impacting, rumbly sound. Although the deep sub bass doesn't exactly resonate, the texture and intricacies of the bass are pretty comparable to the rest of the competition. I could put the exploitative character of bass on its well-established control and speed, but I'd rather not. The sub bass has a strong punch and pleasing rumble. Overall, the bass region is quite well controlled and packs punches and extension with high volume.

Technical Performance​

I'm quite impressed with the technical performance because these products compete fiercely with those in this price range and perhaps even those above. The stage is really spacious and broad, and the imaging is crisp and clear, I must say. Additionally, the distinction is extremely well done. The resolution is high, and the detail recovery is excellent. It looks like the pace is incredibly quick.

Soundstage, Sound Imaging & Separation​

Unexpectedly, the holographic sound stage covers a wide area, primarily on the left and right. Presentation that is crisp and clear enhances the imaging. Every element has enough space to breathe and can be pinpointed, and the distinction is quite apparent and far away.

Speed & Resolution​

The response now has a really fantastic resolution and adequate detail retrieval throughout. Attacks and decays of notes happen quite swiftly, and they resolve just as quickly. Such performance at this pricing point astounds me.

Sound Impressions​

Sources​

Tempotec V6 - When paired with the V6, the C2 sounds incredibly lively and clear. The treble is as expansive as ever, and the midrange is presented forward. The bass has excellent control and packs a powerful punch. The staging and imaging are excellent, and the technical performance is amazing. The resolution has also been considerably accomplished. To be completely honest, I like this coupling. Of the two, it appears to be the best.



iFi Hipdac - The presentation suffers when C2 is combined with the hipdac in terms of stage and resolving ability, but the timbre improves and takes on a more genuine tone. While the mid range is more forward and presentative, the treble is less expansive but still sharp. The mid bass of the bass seems to have more solidity, and it also sounds a little slammy. Although the technical prowess decreases slightly, the tonal performance sounds more authentic overall. I find the coupling with the iFi hipdac to be pleasant but not to my taste because it sounds so generic and regular.

Conclusion​

I'll wrap up this review by saying that I was really happy with the C2's performance. When TinHiFi produced a fantastic IEM like the C2, this new series entry in the price category makes a lot of sense. I heartily suggest this IEM to anyone who enjoys a light, airy presentation with neutral tuning.

Mecha genre is a kind of science fiction literature that revolves around mechanical robots, mostly humanoid-types. It has become an integral part of anime culture ever since and it also inspires some advances on engineering of Japan's robotics industry.

This is my second review article for TINHIFI, and we in audio enthusiast scene already know the reputation of TINHIFI and its contribution in the history of the Chi-Fi movement with their venerable, TINHIFI/TIN AUDIO T2. With their years of experience in audio manufacturing, they are very knowledgeable the current trend in audio scene and decide to release a product that will be more appealing to most listeners.



Presenting TINHIFI C2 Mecha Warrior, TINHIFI's answer to ever-changing, more fiercer competitive product in entry-level segment in the current audio market as the under $100 keeps evolving the quality of tuning might challenge the realm of midrange segment. TINHIFI C2 has a single driver setup and it was housed in a lightweight aviation-grade aluminium CNC milling process to ensures uniformity in quality and structural integrity.





The type of transducer that was in C2 is a 10mm dynamic driver with a hybrid composite diaphragm consisting of Polyurethane (PU) and Liquid Crystal Polymer (LCP) in a dual cavity design. These hybrid composite will deliver a very responsive, more sensitive sound with lower rate of distortion. The CNC-milled aluminium shell chassis takes some inspiration from design cues from Campfire Audio Andromeda then combines it with some design elements inspired from a mecha design. Since the T2 DLC, TINHIFI has changed its preferred type of connector and it was also implemented on C2 , a 0.78mm 2-pin connector.




Fitting-wise, it is quite comfortable and inserts well into my lug holes without any discomfort. The choice of its shell design gives me some uneasy glance due to its outline edges but it proves me wrong, it doesn't hurt my lug holes at all. It has a decent sealing that blocks some noises from the outside surroundings.





As for product packaging, TINHIFI takes rather a more simple and logical inclusions but might be too spartan for its given price. It was packed in a white-coloured square small box with a brand, product model and a mecha illustration at the front, some basic specs at the right side and company address with some QR codes at the rear.


Here are the following inclusions in the box:

■ TINHIFI C2 IEMs
■ SPC parallel wired stock cable with an L-shaped termination plug.
■ 5 pairs of extra black ear tips in different sizes.
■ Contact card
■ Instruction manual/ warranty card




TINHIFI C2 is an easy to drive one that a decent output source will amplify this set very well with good dynamic range and amplitude.


Like the TINHIFI T2 DLC, C2 takes a U-shaped sound signature as it has an emphasis on lows and highs and a bit recessed midrange in the overall frequency range spectrum. It exhibits a bright and crisp tonality that detail retrieval will absolutely love.


LOWS/BASS:

C2 has rather a tighter, penetrating and solid bass response. It has a more sub bass-focus tuning that gives a substantial deep with a perceived rumbling and reverberation on every single bass track that I'm throwing either Synth-pop or old school Hip-hop ones as I clearly hear those synthesisers and electronic drums.

Mid bass somehow has an enough texture that it doesn't sound wobbly and too malleable in my liking. It gives a rumbling and resonant sound on bass kicks, a more rasping and broad sound on bass guitars and sufficient deep and gravelly vocal quality on bass-baritones. All I can say is that the bass register remains clean and well-separated as I don't hear any frequency smudging across the overall sound spectrum.



MIDRANGE:

As expected to a U-shaped sound signature, it is in a tad notch in the overall presentation. It has a balanced texture on both vocals and instrument. It seems that it gives more definition on female vocals than male ones as it has crisp and clarity in it. Females voices in different vocal types and pitch has this regal and silvery feel but I have some fuss about, most vocals even the males have this characteristic that it has some occurrences of being coarse grained and raspy that I find it a bit unrefined in my hearing. Male vocals have this gruffness at the same time resonant sounding.

Regarding instruments, Strings like guitars (acoustic or electric) and violin have this crisp, lingering and vivid sound. Brass like trombones, trumpets and horns have this brassy, intense and metallic sounding. Woodwinds like flute and saxophone has a bright, brilliance and a tad of shrillness on them. Percussive like snares have this clattering and penetrating effect on every strike. Toms and field drums alike seem to have full and sonorous sound while marimba l has this resonant and lustrous sound. Celeste takes a bell-like and glistening to add more that "heaven-like" sound and lastly, the Piano sounds rather bright and vivid like most modern ones which I find a bit exaggerated.



HIGHS/TREBLE:

Treble of TINHIFI C2 is bright, somewhat velvety and with a modest amount of air on it. It does have some noticeable raise and peaks on the frequency response between presence up to brilliance treble region. As I mentioned about the raspiness on vocals. It does exhibit some grainess and a tad of grattiness in general but here's some interesting snippet, the sibilance is well-controlled and smoothen up a bit.

Cymbals have a shimmer and a good amount of sizzle but there are some occasions that it exhibits being splashy but it isn't really a major concern to me at all, just a quibbling matter. Hi-hats seem to have a very distinct sound, a dry and shortened soughing sound. It also has a good amount of air on it to add better harmonics.



SOUNDSTAGE, IMAGING & OTHER TECHNICALITIES:

In overall sound field dimensions, soundstage width appears to be above average with its perceived spaciousness, it has good height but depth is an interesting case on this one as I find it variably immersive and can't fathom the perceived distance between front to back.

Imaging performs decently it projects the basic gradual panning from left to right which makes a stereo experience on the C2 very compelling. Separation and layering on this set seems fine as I hear a decent spacing of instruments and vocals then at the same time, a distinctive placement of frequency and dynamics of specific instruments and vocal tone that playing instrumental score track carry it out properly.

Coherency of this set is quite impressive given how fast the drivers of this one perform homogeneously. As for timbre, they are rather on the bright side given how it was tuned.

As for resolution capabilities, due its tuning, it has an edgier definition on micro-details with a solid macro-dynamics as it has a substantial in note weight presentation.



PEER COMPARISONS:


KIWI EARS CADENZA

● They are the closest possible match-up, both are at almost the same price bracket and also the same single DD implementation but transducer tech's are quite different, Cadenza uses a beryllium-coated diaphragm compared to a composite one of the C2.

● They are in the same playing field when it comes to the tonal curve, both have U-shaped sound signatures. Cadenza takes more natural and perhaps a tad warmer to have a "safer" t une due to a laid back nature, it has less shimmer and less air compared to C2 and yet it has a more cleaner presentation.

● Technicalities-wise, Cadenza has a mere average performance, as it has a narrower sound/speaker stage, mediocre separation and layering. Resolution definition is rather blunted but on timbre, Cadenza executes it in a very organic manner.



TRIPOWIN CENCIBLE:

● Another product that is one of the contenders of C2, same single DD set-up but diaphragm is a graphene one, Shell housing is different as Cencible's shell was made of resin.

● Even in tonality, they are strikingly similar, taking a bright U-shaped sound profile. Cencible has more prominent mid bass while C2 is focus in sub bass, both midrange have similar balanced texture, but Cencible has a tad more warmth, vocals are slightly cleaner though it has some instances of being too shouty. Trebles of both products perform similarly as they have both a shimmer and modest amount of air on the brilliance region.

● Technicalities are also similar with exception of separation and layering as Cencible performs this area in a mediocre manner as there are some complex instrumental tracks that Cencible sounds a bit congested and disordered.



TINHIFI seems aggressive recently in releasing products in the entry-level segment. Along with C3 which I will review later and T4 which I don't have right. I am still thinking and trying to process it out why this company took this direction to market their products in a simultaneous manner at the same price bracket which is under US$50/£41.


For sure that TINHIFI C2 will have its supporters and critics on how it was tuned. But for me, C2 is decently tuned with some good technical performance for its asking price but to market it at an already very competitive IEM market, especially on a price category under US$50/£41, C2's appeal to new audio enthusiasts is quite uncertain.

P.S.

I am not affiliated to TINHIFI nor receive monetary incentives and financial gains as they provide me a review unit for an exchange of factual and sincere feedback from yours truly.

Once again, I would like to KEEPHIFI for providing this review unit. I truly appreciate their generosity towards me and other reviewers.

The Tin Hifi C2 Mech Warrior have been sent to me by Linsoul in exchange for the publication of this review. They have not requested anything specific so, as usual, I will aim to be as unbiased and sincere as possible in my review.

As always, a non affiliate link to the C2 Mech Warrior via Linsoul can be found in the version of this review published on my blog (link to my blog at the end of this post).



Intro…

I actually received 3 sets of Tin Hifi IEMs from Linsoul at the same time, the C2 Mech Warrior, the C3 and the T4 plus. For no real reason, I decided to start with these and move my way up through the numbers.

The C2, which are also called the Mech Warrior (for reasons I am unsure of but I guess it is due to the aesthetics) are another set that enters the extreme budget battle, coming in at around 30€ (at the time of writing this review).

They feature a single dynamic driver which is supposedly a new development from the brand and as far as looks, they certainly break away from the usual Tin Hifi offerings.



Presentation…

The C2 arrive in a small white box with a sketch of a robot on the cover and C2 Mech Warrior written beside it. I really have no idea what a Mech Warrior is but I actually like the fact that it is not the usual anime girl that we find on so many packages.

Inside the box there isn’t a lot but there is enough for us to grab the IEMs and get listening. Apart from the IEMs, we get the cable and 6 sets of silicone tips.

That is it as far as presentation, simple but nothing really to complain about.



Build and aesthetics…

The shells are completely made of 6063 aviation-grade aluminum and opt for a shape that is very reminiscent of some CFA models, or even some of the older KZ models. WHile not completely original, it is a change from the usual Tin offerings and while the shape is a little strange, I actually find them quite comfortable. They are not the most lightweight of IEMs but are nowhere near as heavy as they look.

The included cable is coloured to match the IEMs and while it uses plastic hardware, I can’t bring myself to complain about it at this price range.

In general I would say that the presentation and contents are ok, nothing amazing but certainly acceptable.



Sound…

All tracks mentioned are clickable links that allow you to open the reference track in the streaming service of your choice (YouTube, Tidal, Spotify, etc.)

First let's take a look at the graph of the C2 in comparison to my usual preference curve.



Starting off with the subbass as always, there is enough rumble for the lowest frequencies to be present, however, I can’t really talk about the subbass without mentioning the midbass at the same time.

The issue I find here is that the midbass is more prominent than the subbass and it is not the most controlled and clean of bass representations. When trying my usual subbass test with “Chameleon”, I found that the midbass took the focus and made itself too much the center of attention. This meant that to actually test the subbass, I found myself needing to resort to isolating the subbass frequencies.

As you all probably know by now (if you don’t, you are about to find out ), I am not someone who enjoys an overly present midbass. If there is enough subbass to compensate and the midbass is clean and controlled, then I do find myself enjoying it a lot of the time. However, in the case of the C2, it has the midbass presence that causes me fatigue and can actually give me a headache after some time.

This doesn’t mean that it is bad per se, just that it doesn’t work for me personally and I do not enjoy the lower ranges of the C2. For example, the low end of the guitar in “Crazy” becomes far too boomy for my tastes, and while it is compensated by the higher ranges, it doesn’t eliminate that sensation, just tries to mask it.

Once we get out of the lows and into the mid range, things do get better. I find that vocals are decent and nicely defined, yet they can find their lower ranges competing with that lower boominess that can bleed into the lower mids.

The upper midrange has a smooth climb to it, reaching quite a nice level of presence in the upper mids of vocals, yet, the extension of the presence is just a little too much. This doesn’t actually become painful for me in the way a 5kHz peak would, yet it does give vocals, such as Johnny Cash in “Hurt”, the sensation of being too flat and dry in these ranges. It is as though the upper mids are a 2D representation of a 3D image.

As we move into the higher ranges, there are a few peaks that help give the C2 a sensation of being a little more open and detailed, yet, again, they seem to not quite be smoothed out correctly. It doesn’t become harsh, although there is some sibilance introduced in the usual “Code Cool” test, but things are just a little… unnatural.

Details are acceptable, although the “fake details” introduced by those peaks I find actually work against the real details of the driver, so it is difficult to judge. Usually I would focus on the lower mids in these cases, to see what detail retrieval can be found in those ranges, but I find that the excessive mid bass makes that difficult to do.

Soundstage and image placement is nothing extraordinary, it’s not terrible but it is by no means above average in this regard.



Isolation is about on average with just the 3 to 4kHz range being slightly above the majority.



Conclusion…

While I can understand others maybe liking the C2, I’m afraid that to me it leaves a lot to be desired.

The midbass is excessive for my tastes, causing me fatigue, and the upper mid range and lower treble seems to be quite unnatural. Again, it is like they are presenting a 2D rendering of a 3D image and it just doesn’t work that well. It’s sort of like a blunt knife, the cutting edge is there but it doesn’t do things like it should.

This may sound a little harsh but with all of the excellent models that occupy this price bracket, I think the C2 falls quite a bit behind.

As always, this is my personal opinion based on my personal tastes, you may love them!

History:
There was a day when TinHiFi was truly groundbreaking in out-put. On February 4th, 2019 Z-Reviews did a YouTube video calling the T2 the greatest thing since sliced bread. At the time I had personally already went through my Chinese budget buying phase and was concentrating on more expensive gear. But looking back I wish I could have been a-part of this budget (flavor-of-the-month) phenomena. You can’t just get a pair of T2s now and call it a day, no the past is gone forever. While there are classics in the IEM realm, companies like TinHiFi keep making new stuff and often it is better than what came before, new driver technology ect, ect. Meaning new stuff comes out and is compared to other new stuff and so on and so on.

I just received the TinHiFi C3, T4 Plus, the TinHiFi T2 DLC and the C2 Mechanical Warrior. Yep it’s nickname is the Mechanical Warrior. Named most likely due to the shells construction which is CNC 6063 aviation-grade aluminum. Compared to the prior list I like the C2 as one of the best. Probably due to looks too, looks actually have a lot to do with how something sounds, but also the fit is nice, as well as the imaginative construction.

PRODUCT SPECIFICATIONS:
Impedance 32Ω±15%
Sensitivity 104±3dB
Frequency Response 10Hz-20kHz
Rated Power 3mW
Max Distortion 3%@1kHz



Build:
CNC construction, 3 pieces with a clam shell design, and extra nozzle creation. Weighing in at 5 grams a piece, they are nether heavy or lightweight but right in the middle, same as size……….medium. Turning them over we find giant L and R makings as well a vent. One vent is on the faceplate out-in-the-open, and the other facing towards the listener just under the nozzle. As far as over-all conduction goes they are both unique and cool looking. The part that faces your ear is relatively smooth gaining wear comfort. Even though they look like they might move around, they don’t. Amazingly I have a wide range of ear-tip personal choices which all work, being the tell-tale sign of a good fit. There is a nice nozzle inset plate with 20 holes drilled in it, as well as a screen for the outside vent on the faceplate. The aluminum has nice gray anodizing for two of the three pieces with chrome on the nozzle. The nozzle has a lip which goes to hold ear-tips on securely. There are three small hex screws which hold the thing together, and for once they are real! Normally they are always fake in this price range, and only give a look of holding the IEM together. The 0.78 two pin receivers are recessed and give-way to a large section of the cable pin mounts in placement. Amazingly many cables seemed to fit fine.


Cable:
Coming with over-ear guides the cable itself works well. The material used to build the cable is not listed. Along with 0.78 2 pins on one end and 3.5mm single-ended on the other.

Packaging:
While continuing with the Mechanical Warrior theme showing a robot on the box, the package remains average for the price asked. 6 sets of ear-tips and well as a warranty card and QC stamp inside of box.






Sound:

Comparisons:
Offering a slight upgrade (maybe) in sound from the more expensive C3, still the C3 offers slightly smoother fit. Upon first trying these out I almost thought the C2 was a hybrid with the better separation and imaging……….but no, standard 10mm full-range LCP+PU Composite diaphragm. Laughably the playback is close to the C3 but imaging is slightly wider and a tad brighter. There may be something to this N52 Neodymium magnetic circuit, and CCAW 0.035mm voice coil? Yep, if they were both on a table, you know which one I would be choosing! Still the over all difference is small if any, so I suggest simply go with which ever you think looks best.

Same goes with the TinHiFi T4 Plus, while it’s many times more money than the humble C2 Mechanical Warrior, it doesn’t sound much different. Maybe a little top-end treble details here and there, but it also sounds the same. The same goes for the TinHiFi T2 DLC, nothing extra ordinary about this playback yet due to subtle differences I would place it in forth place.




You will note the sound representation discrepancies between the two C2 graphs. A perfect example of how graphs don't possibly show the complete story, yet they are valuable none-the-less to help show us what we hear partially. As usual I take the upper areas as simply ideas as to the frequency response, yet the most important is where the pinna gain starts the amplitude of that pinna gain and its relationship to the lower midrange and bass areas.


The Salnotes 7Hz Zero
TANGZU Wan'er S.G
TinHiFi C2 Mechanical Warrior

Sound comparisons continued:
This is where it gets good. This is an interesting battle as the note the C2 has no (Possible) 8 kHz peak like the TANGZU Wan'er S.G. Debatable how the 10 kHz peak is represented with the Zero as much of the time 10 kHz and after is often not reliable. Such as the C2 10 kHz peak too. When in reality that upper section doesn’t carry all that much influence anyway, being thin and (as it maybe could be) responsible for cymbals and the like? Yet what is different is how each subtly sounds. With the Zero having the least bass presence, the TANGZU Wan'er S.G being the most forward. That’s right see the approaching 2.8 kHz pinna gain the TANGZU Wan'er S.G has? That right there is in the most highly sensitive area of the hearing where small changes make huge differences…….and it sounds like it, between the Zero and TANGZU Wan'er S.G. Where the C2 pinna gain shows roughly though the same TANGZU Wan'er S.G place, it’s due to the boosted upper bass that seems to decentralize the pinna gain effect?

And that my friends is a great comparison to what you’re getting if you choose one of the three. To summarize the Zero has less bass of the three and the C2 has the most upper bass energy which adds a style of warmth not present in the other two.

The sound in general:
TinHiFi are playing it safe in a way. Not ruffling any feathers with this tune, kinda offering an accessible and entertaining tune which while sounding even and correct, doesn’t take any chances either. In so many ways the TinHiFi T4 Plus, the C2 and C3 all sound the same. This could be considered in that they are family and share the same tuning team possibly? Yet as the sound description follows, there are no chances taken and nothing really drastic to be expected. Maybe I’ve just heard too many IEMs? Still I don’t think so, my ability to discover character is still with me, and while the C2 looks very different from the outside, it’s simply one of the pack. Don’t get me wrong, there is nothing really bad here, the sound is admirable and fantastic for the price asked, it’s just if you had the C3 or the TinHiFi T4 Plus….already, there would be no use in getting the C2, unless you loved the shell and joined well with the fit. Remember too, the C3 is probably going to be the best fitting of the three? The “tank-look” is probably what sets the Mechanical Warrior apart?

Sound details:

Bass:
A subtle V shape allows for authoritative grooves and sways. It took a while for burn-in to open-up the stage and smoothness, so don’t become disappointed how they sound out of the box. It’s that smooth upper bass that is both blanketing yet still fast, yet not as fast as some sub-bass experts seem to have become in IEM land. And in totality I’m on-board with this style of consumer tune, especially since it’s careful and complete.

Treble:
There is a slight expression of grain in the treble reaches, a character if there is any to be found in the C2 strict demeanor. While not really dark or rolled off, it is in the most careful of ways submitting just enough air to get involvement and stage presence.

Midrange:
While complete sending both of male and female vocals into audibility, there is still the backdrop of V support making the C2 Mechanical Warrior fun. This obviously is not a vocal specialist set, still that’s the magic with this tune and probably the main reason TinHiFi are propagating such IEM proliferation in numbers? Really the Mechanical Warrior does it all.

Pace:
While showing the upper bass presence, there is still a balance that gives wonderful pace regardless of obstacles in the way. There is not really any sleepiness here, and it many ways the pace character is so middle of the road it seems to avoid description? Simply adequate and correct……which leads to the soundstage abilities.

Soundstage:
Strangely this was the single area that changed the most with my usage. That and a smoothness of tone. But all I can say it get a pair of wide-bore silicone tips on these and do a few days of burn-in and watch the magic take place! Yep. That treble roughness is always there, but imaging of musical elements seem to have traveled out even further into entertainment. Yep, soundstage is critical to making the C2 all it can be in the end. Why? Optimizing soundstage offers a separation and itemization thus reality in replay found. Stuff that’s in a better soundstage can be perceived as more real. I ended with the Sony Walkman WM1Z with MrWalkman’s firmware, the ISN G4 cable, but definitely try wide-bore tips as a way to expand the soundstage!


Conclusion:
The TinHiFi C2 Mechanical Warrior finds itself with a unique shape, though the sound is efficient but also kind-of ordinary. Does that ordinary make it bad, no? Why? Simply because the C2 is a lot of sound for the money. It’s in may ways the correct sound for modern music offering a nice bounce and pace. Even vocals are represented with the needed light! Two special eccentric areas of personality become not deficits but what little there is to sway it from the rest. Namely the slight distortion of the treble and the upper bass energy. Strangely it’s this character to the treble that I in fact like about the C2, as a slight example that it’s not perfection that we are after, perfection will never be achieved, but character is what we are drawn to. Same as the warm blanket the upper bass is displaying. These are the two aspects that I think about when I grab the C2, that and the soundstage imaging. Really there is a lot here for just $29.00, a lot more than you would guess. Most of this comes down to vary small differences in-fact. We can wonder how those differences are obtained? Is it the CNC chamber the 10mm is resonating into? Are the walls of the C2 somehow responsible for different reflections of sound waves inside the shell? Are the reflections added to the sonic response somehow different than the 3D printed shell of the TinHiFi C3? Does the C2 steel plate with 20 holes drilled into it sound different than the C3’s wire mesh? Do they in-fact use the same driver? Are any of these questions really that important?

As the C3 is more expensive at $49.00 and, yes it feels slightly better inside the ear, but the C2 doesn’t feel bad in anyway, just not as silky…….I mean look at the Mechanical Warrior…..does it look like comfort was the main design strategy? Probably strength and modern CNC design was looked for? And while I should like the C3 better, I don’t. Don’t ask me why, I just spent the time to write the above paper to try and figure it out? But if you’re like me and you become endeared to IEMs due to their inherent creativity and specific differences, there are a few to be found here. The Mechanical Warrior may be designed for a much younger target user group than I? Yet I find it special, special at any price. They gray color, the real hex bolts, the way the inner shell design has been smoothed out, with the outside looking like some kind of bio-mechanical implant. The look is almost like a prosthetic science fiction robot ear, a separate ear which lays onto your ear cavity. And still you find the form and fit is comfortable, even though it doesn’t look like it. This is 2023 already and such spectacles of science fiction are all around us, everywhere you look. This IS the future, we are living in it, a far cry from 1997 when IEM started to emerge. Advances in design both in build and sound are included in an IEM purchase today. This technology is advancing and sound per dollar spent values are on the rise. If you find the Mechanical Warrior intriguing, it’s for good reason, and for the price it costs you have absolutely nothing to lose, except of course if you already have the C3, well then it’s more of the same.

The packaging is cool and inside the IEM are well made even if it's very similar to the RevoNext QT2, inside is a new generation DD and the sound of course is much different. I was a little disappointed there was no case or pouch that tin has been known for with even the lower end IEM. I found accessories minimal. The cable is not the worst by far, but it was adequate, I really not a fan of the deep two pin they decided to use just like RevoNext used in their IEM.

Now let's get on to the sound.

There is a lot to like here, its well balanced and has good technical abilities but it failed to wow me on even the best equipment it comes across boring and vanilla to me. With competition at a high it fills only a small niche of listeners looking for more details and abilities over enjoyment in my opinion. This said its not bad but a little too hyped in my opinion. This falls behind The C3 and T3 plus in terms of being able to be enjoyed with all types of music and enjoyability.

Bass: Has some depth but falls in-between neutral and enhanced a little in the Sub-Bass. Sub has a good depth when called upon but doesn't fill the bass head needs by far just good texture and a adequate rumble Bass in general is speedy and tight its not bad just a little too light in the Mid-Bass that presents well but lean in my opinion.

Mids: are yet another IEM where they are centered perfectly like the Gimlet, but the C2 mids are rather thin and have good details but are just that good not great and nothing special.

Treble: Is open and airy details are decent, but it has a well-controlled and rather smoothed over overall presentation.

Soundstage: Is good in accuracy and has a decent width but is lacking in depth and is not good for gaming at all.

Afterthoughts: The Tin C2 is a departure from the traditional Tin we know, and it is well made but it did nothing for me comparing it to the Qinglong or Gimlet and a few others I have recently tested. I would not say it's bad it's just not my cup of tea and boring to me. It has merits and this is just my opinion. I initially liked it in my video but in retrospect it's just okay.

Introduction & Packaging

Tinhifi C2 is the one of the firsts in their new product line along with the C3, a departure from their T-line and P-line. The C2 is currently priced at $29, sporting a single dynamic driver with PU+LCP composite diaphragm, solid CNC aluminium housing, and 2-pin 0.78mm recessed jack. The stock cable is a pretty standard 1.2m cable terminated with 3.5mm plug (materials not specified). Carrying case is not included. There are 6 sets of eartips, 2 sets of each S, M, and L sizes (they do not seem to be different, so the extra pairs are backups). At this price point, I can understand the very spartan packaging, but I was really expecting at least a carrying case. It's a small matter though. Can the Mech Warrior complete its mission to dominate and destroy the under-$50 market? Let's find out!




Sound Impression

Listening setup:

• Topping D90SE/A90D stack (single-ended)
• Fiio M11S (single-ended)
• Questyle M15 (single-ended)
• KBEAR 07 L eartips and stock 3.5mm cable
• Local FLAC, Tidal, or Spotify depending on the availability of the music

The C2 has undergone a 24-hour burn-in prior to testing. Unfortunately, I don't get a good seal with any of the default eartips, so I used my KBEAR 07 L eartips for the entirety of this testing session.

Graphs are courtesy of Ian Fann. Listening was done prior to looking at the graphs.

I understand that with IEMs, the shape of the ear canals, fit, eartips choice, and personal preferences can greatly affect the impression of the IEMs. I try my best to describe my experiences, however your experience may vary depending on your listening setup. While I might add some measurements and graphs for a certain degree of objectivity, it is nevertheless a subjective opinion.

In general, C2 is tuned to a U-shape/mild V-shaped frequency response with a very smooth midbass and clean midrange. The treble does exhibit slight harshness that I'd describe as "crunchy", but some people might enjoy it as it does gave some sensation of improved resolution.

I guess C2's technicalities is still comfortably within the price range. Soundstage is its strong point, there are enough space for each instruments to breathe. Imaging and layering are decent, helped with that safe tuning. The resolution is pretty good with plently of upper midrange texturing. Honestly, at this price point, I don't think there is any complaint about its sound quality and performance.



Bass: Textured, fast, and snappy.

Midrange: Decent presence, no recession. Male and female vocals are both equally well-reproduced.

Treble: Slightly grainy, decent amount of air and good amount of details. Non-fatiguing.

Technicalities: Above-average soundstage. Decent resolution, imaging, and layering.

Select Comparisons

Moondrop Aria ($80)


From the first time I listened to the C2, I am reminded of a very similar tuning... That is of Moondrop Aria. When I eventually compared the graph, it's hard not to draw similarities between them. However, Aria is noticeably smoother in the upper mids/treble region, giving an overall more 'meaty' tonality. Build quality-wise, Aria might have a slight edge with a heftier, more premium feel to it. However, the C2 is really close in almost all technicalities at much lower price point. It is quite an unfair comparison as the C2 is a much newer product and would have benefited from the experiences of the older products like Aria, but it kind of shows how insanely fast the IEM industry improves.

Kiwi Ears Cadenza ($35)


Cadenza is also my recent favourite. I delayed this C2 review since I was waiting for my Cadenza to arrive and would like to make a comparison (review soon too). The Cadenza has much better bass extension and subbass rumble, with a fuller midbass response, courtesy of the Beryllium-plated driver. C2 has a nimbler presentation with better resolution and texture with wider soundstage, but feels a bit lean overall. They are both very competent sets at this price range, so it really comes down to preferences between them.

7Hz Salnotes Zero ($20)

7Hz Salnotes Zero is currently my daily driver for casual listening. Here, it serves as the sub-$50 'referee' for me. In comparison, C2 is slightly more warmish with a more forward midbass. Midrange presentation is pretty similar, but I prefer the cleaner vocals on the Zero. C2 has better treble and air. The perceived resolution is subsequently better on the C2, as well as better soundstage. Similar to Cadenza, both are very good sets, so it came down to preferences. If you want a more fun sound, C2 would be a good choice, while Zero has a more neutral, reference-like sound profile.

Conclusion

Tinhifi C2 is the proof how fast the IEM industry moves. To rephrase the words from MKBHD, "Good (ear)phones are getting cheaper, cheap (ear)phones are getting better". In more ways than one, C2 is the epitome of that. continuing the trend of trickling down the technology from higher ranks of IEMs. C2 did to Aria, what Aria did to KXXS. While I don't think the C2 Mech Warrior completely achieved its seek-and-destroy-the-competitions mission, it did show how formidable it is. If you're looking to get a stylish IEM at around $30, it's hard not to consider C2.

General Info/Build/Comfort/Packaging
TinHifi is a name the Chi-Fi community is very familiar with. They offer budget models all the way to mid and high tier models. C series is their new lineup which has new packaging and also, according to TinHifi, they will be focusing on the sound quality and also competitive pricing. I have the C2 with me today and the build and design is indeed very different from their usual offering. Starting from the build quality and design, it features an aluminium shell and the design is quite rugged.

In terms of packaging, it came with eartips, cable and the IEM itself, this time they omitted the storage pouch, i guess they are reducing the cost on the packaging and focusing all on the sound quality itself. The IEM itself is very solid and after using it for a long listening session, i did not find any discomfort throughout my listening session.

Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far

Sound Impression
TinHifi C2 sounds U shaped to my ears. The mids are not as recessed as the usual V shaped, treble and bass is nicely done without being overly emphasised. Timbre sounds natural to my ears, tonality to my ears is on the slight bright and crisp note weight.

Bass

• The bass on the C2 is nicely done, which is quite rare for the price point, usually it is either too much bass or very lean
• Sub bass has got the satisfying rumble to it, just the right dose in terms of quantity, nowhere near basshead level of course
• Mid bass is quite controlled and clean, tight and speedy as well, Listening to Slipknot is satisfying as it is able to keep up with the pace without sounding muddy
• The overall texture is quite good for the asking price, can’t really nitpick

Mids

• The mids here are not forward nor recessed, just right to my ears
• Vocal presentation is good for both male and female overall, but i’d prefer if it has got a slightly thicker texture, then it will be very good, still good in my opinion, but can be better, considering a this price point, can’t really fault it that much
• The pinna gain is quite standard and i don’t feel fatigue listening to them for long session, nicely elevated without causing it to be shouty

Treble

• Treble is smooth and non fatiguing with enough energy
• Good amount of air as evident on complex track where it doesn’t sound congested
• Detail retrieval is good for the asking price, not exceptional but you can’t really fault it that much considering it’s price

Soundstage/Imaging

• Soundstage is good in terms of good width and height, a little lacking in terms of the depth, but it sounded very spacious overall
• Instruments can be pinpointed easily even on busy track like Slipknot’s People = crap

Driveability

• C2 is fairly easy to drive, straight out of my Macbook’s 3.5mm port, it sounded very good
• Apple’s lightning dongle is also very capable of driving C2 to its maximum potential
• It does scale with source but not so much with amplification, slightly better bass control in terms of tightness, you are not losing out much if you don’t have an amp
• Good enough to drive C2 if you have an entry level or mid tier dongle

Comparison (Kiwi Ears Cadenza)

• Cadenza is slightly more expensive than C2
• Both sound profile is quite similar in terms of both are having the same U shaped profile
• Cadenza for a slightly laid back listening experience while C2 will be a little bit more analytical
• Both have good fits but differs in terms of build quality, C2 is Metal build and very sturdy and solid, while Cadenza is plastic, but also of good quality and lighter

Final Thoughts
All in all, C2 is a very solid contender in the segment, it is balanced sounding and offers good technicalities for the asking price, a very solid product and i highly recommend this for those who are in the lookout for a budget IEM that offers good technicalities without breaking the bank, otherwise if you prefer a slightly more laid back listening experience, Cadenza is it.

INTRODUCTION:

Tin HiFi, the brand based out of Shenzhen, China is a well established brand among the audiophiles. They do have a separate fan base for their unique sound signature and lately to acquire even more audience they have turned towards a different signature led to massive success like the T3 Plus. To continue that growth they did release a new product to the product namely C2! And in this review let’s check out how well they executed this package.



SPECIFICATIONS:

Custom-developed 10mm Dual-Cavity Dynamic Driver.

Newly-Developed PU+LCP Composite Diaphragm.

CNC machined aviation-grade 6063 Aluminum alloy ear shells.

2-pin 0.78mm connectors.

Impedance: 32Ω±15%.

Sensitivity: 104±3dB.

Frequency Response: 10Hz-20kHz.

Rated Power: 3mW.

DESIGN AND FIT:

The design is pretty industrious with a great aluminum build. The screws on the faceplate do add a touch mechanical personality to the IEM. The ergonomics are pretty good too where no pain had been experienced even after longer listening sessions. The stock cable is pretty good with a nice texture and an outer sheath that prevents the frequent tangling of the cables.

The stock ear tips are however on the average side which needs more time to find a perfect seal. After finding a good seal with those tips if you try to change the position of the iem the seal tends to go away which is quite irritating. Tin should have provided the T3 Plus ear tips for a complete package.

SOUND:

The sound profile of the C2 follows a pretty U shaped curve. The bass here is nicely elevated with controlled presence thus not making the track too dark or muffled out. The Midrange is kept as natural as possible with excellent layering and positioning of the instruments. The treble is done extremely well for the price with excellent detail retrieval. Each and every note is brought out well with natural tone and timbre. The technical aspects are stellar in the C2 for the quoted price. Let’s check out in detail about the sound in the following sections.

BASS:

As a Tin product they usually stick with their in-house signature which is more of a neutral to bright sound but in recent days the brand is trying out different signatures as we saw in the T3 Plus and it even worked out well. The same thing happened with the C2 too!

SUB BASS – The sub bass here is tastefully done with nice reach and depth. They do provide that satisfying rumble in the low end without interrupting the mid bass section. Even though it's not a bass head approved it will still satisfy them with its controlled and attacking bass section.

MID BASS – The mid bass is controlled and comes to the stage whenever they are called by the track. As a common term I can tell the bass here is CLEAN. Those kick drums and the bass instruments are brought out really well without any congestion. No hindrance of the notes are observed, rather everything is very transparent enough without darkening the background too much. The bass body is adequate thus providing a nice adequate fuller sounding experience but many might find this to be pretty lean due to its open sounding nature.

Overall the bass in the C2 is pretty satisfying with excellent control and cleaner presentation. In this budget segment this is the character very difficult to find but the Tin HiFi has done a great job here! Definitely the bass here will please everyone out there.

MID RANGE:

The mid range here is presented well with proper positioning of the vocals and the instruments. Even though it’s a U shaped presentation the mid range however felt nice and engaging.

LOWER MID – The lower mid section nicely carried the body presence from the bass section thus they sounded warm enough.

UPPER MID – The upper mid section has a nice elevation which is never disturbed in the longer listening sessions. The upper mid presence made the female vocals and the percussion instruments sound bright enough. The listening experience is engaging and the tonality is kept natural with a nice smoother touch.

The vocals are placed in an appropriate position providing a nice engaging listen. The staging being on the wider side the layering is done impressively here. Different depths of notes are nicely layered out thus representing a richer experience.

Overall the mid range does sound richer, engaging and well layered. Being placed in this budget segment this kind of tuning makes me go AWE!



TREBLE:

The treble section is masterfully tuned with a nice extension in the top end. The upper end is not restrict where this C2 allows the instruments to breathe the air freely making the overall sound to appear bright enough and detailed.

The cymbal crashes and the trumpets sound natural and vivid. The attack and decay of the instruments appears precise. The timbre of the instruments are pretty natural and realistic. Most of the budget IEMs does have that colder timbre to represent a fuller tone but this one being natural realistic preserved the original taste of the track.

The shimmer and brilliance in the top end is executed very well where there is more than enough room for the notes to breathe making them appear more lively and engaging.

TECHNICALITIES:

LAYERING AND IMAGING: The star aspect of the C2! The different depth of notes are nicely layered out without any congestion and difficulty. The placement of the instruments are done exceptionally well where one can easily spot out the placement even in a busy track.

STAGING: The staging is wide enough with above average in height. The spacious staging also led to a grand presentation of the music. Along with that well extended treble the whole experience felt lively and engaging.

The channel transition felt pretty smooth with no stutters. The detail retrieval and the track separation are just stellar in this C2 considering the price segment this is placed. The resolution that this C2 brings on to the table is pretty impressive.

VERDICT:

C2, the latest offering from the house of Tin HiFi is an awesomely well executed package and most importantly they priced it right on spot!. Tin HiFi from their recent launches of products they never disappointed the consumers and the same follows to the C2! Sounds extremely good ! The 10mm Single Dynamic Driver with PU + LCP Composite Diaphragm does magic in the sound department.

The sound of the C2 follows a U shaped curve thus having an upper hand to the bass and the treble section. Thought that mid range will get dampened but thankfully it's beautifully tuned! The bass here is well controlled and bodied. Has good reach yet providing that cleaner presentation and track separation. The mid section is nicely placed in the presentation where each and every note is brought up forward giving an adequate emphasis. The resolution that this 30 usd set brings to the table is very impressive!

The layering being the star aspect and the staging being on the wider side the whole presentation felt grand enough, engaging and lively. The treble section is well extended allowing the instruments in the top end to breathe freely making them sound richer and bright enough. The tonality and the timbre of the instruments is pretty natural and realistic with a touch of brightness to add sparkle to the listen.

The design is very industrial as Tin HiFi says it in their own term “MECHANICAL ''. Those aluminum built with the screws on the face plate really look very mechanical and robotic. The provided stock cable is of great quality too which doesn’t get tangled for the most part. The ear tips however could have been improved since they are not that excellent in providing a nice seal.

Overall, the C2 is just stellar in my opinion. Under 30 USD I usually don’t recommend products since mostly they do sound more or less same with darker or more brighter signature but the C2 sets itself apart in this price segment! A cleaner sounding and a highly resolving gem yet providing that required fun for engaging listen making itself a CLASS APART from the competitors!

=============================================================Sound signature:

• The Tinhifi C2 has a neutral-bright, or mild-v, signature that leans toward the brighter end of the spectrum in some sources. The amount of clarity and cleanliness in sound you get on this IEM is almost on par with the Tinhifi T4, my personal favorite Tinhifi IEM among their lineup, followed by the T3 Plus.

Lows:

• The Tinhifi C2 exhibits an elevated, quick, punchy, clean, and impactful bass. It never came across as boomy or slow during my tests. Its midbass is more dominant than the subbass, but not by much. Bassheads on a budget may still enjoy the C2's bass, but they may notice that it does not dig as deep as other basshead sets in this price range, such as the KBEAR Rosefinch.

Mids:

• The mids are slightly recessed, but not to the point of sounding distant. It is still present, detailed, and free from any midbass bleed without sounding too thin, which I really like. Lower mids have good thickness, detail, and texture, but they aren't as lush or smooth as their Tinhifi T3 Plus and aren't as thin as their T2 and T3. Upper mids are elevated with very good air, clarity, and sparkle. This isn’t sibilant, harsh, or peaky by any means, but those people who are sensitive to upper frequencies may find this "too much to their liking." I do believe that this is because of the LCP driver’s nature, because I also experienced this type of midrange quality on some of the LCP-based IEMs and earbuds I encountered and owned.

Highs:

• Moving on to the treble, it is well extended, airy, and has a good amount of sparkle. It was noticeably more elevated in presence when compared to the lows, but it never became distracting or overwhelming on my tests. Cymbal crashes exhibit good definition and extension. Detail retrieval was average to above average during my tests, as it managed to present most details with ease.

Soundstage, Imaging, and separation:

• The Tinhifi managed to balance the quality of its tonality and technicalities in this IEM. and it really shows. The soundstage is wide, with average expansion. Separation and layering are clean for their price, with minimal congestion on very busy tracks but not up to the point where everything becomes blurry. I can even say that in this department, the C2 has better separation and layering than their T3 Plus. Imaging is accurate and can present vocal and instrumental positioning with decent accuracy.

Pros:

• A well-tuned, all-rounder IEM for 30 USD.
• One of the best tuned Tinhifi IEM in my book, surpasses the Tinhifi T4 which was my personal favorite of their products (subjective).
• Very good balance between tonality and technical quality.
• All-rounder, mild-V-shaped sound signature.
• Well-controlled, punchy, fast lows.
• Clear, detailed mids.
• Extended, airy, detailed treble.
• Very good technical performance, price-wise.
• Sturdy, metal build quality.
• Decent, soft eartips.
• Very good fit and comfort.

Cons:

• Upper mids and treble may come across “too sparkly” or “grainy” for some people, especially those who have low treble tolerance. It is by no means sibilant or harsh though.
• Fit may become fatiguing for some people due to its edged corners. I personally had no problems with it, but it may be experienced when it is fitted flush or closer in your ear.
• Minimal accessories. A pouch or a case would’ve been a good treat for everybody (my nitpick).

Verdict:

The Tinhifi C2 shows that you don’t need to spend too much just to get very good sound quality. At this price range of 40-60 USD, the Tinhifi T2 managed to truly balance the fundamentals I seek. Its clear, detailed sound, accompanied by very good quick decays, enables it to stand up to most genres and pairings you throw at it. This is probably the best budget LCP IEM under 50 USD in my book, assuming that you are looking for a brighter sound signature.


Pairing recommendation/s:

• Source: I find the Tinhifi C2 easy to drive. However, I do recommend using a 2vrms dongle or a dedicated DAP for good measure.
• Eartips: The eartips are soft and comfy enough for daily usage. However, you may use your preferred third party eartips.
• Cable is more than enough for the most part, but you can always use your preferred cable.

Thank you for reading!
