TIN T4 is one of those IEMs that can generate, idd generated mixed emotions, at least to me.
The very first time I auditioned them I almost hated them as I was assaulted by their 6KHz peak which made them come accross unacceptably bright even while playing a treble-friendly genre such as bebop. I almost trashed them after a week. Then, with a process in the end quite similar to how final E4000 sucked me in, while listening to some genres with other IEMs I noticed where such latter drivers were lacking vs my memory of the “other” T4 parts, and I called them back into service. Once, and then again. And again.
Yes the 6K peak is there but it can be tamed with some very easy EQing if really wanted, revealing a solidly clear performer with such a neutral signature as to almost sound arid, if it weren’t for that modest but decisive midbass dry coloration and treble airyness granting a world more of engagement, but taking all care to not even coming close to imposing a definite personality.
T4’s balance between neutrality and endogenous dynamics is frankly difficult to replicate, and even some of its single features are not easy to upgrade. Take its sub-bass for example: it’s kept scarce on the altar of neutrality, hoewever even taking that in absolute terms, finding another IEM with a significant higher sub-bass presence strictly paired with uncompromised high speed and tightness on one end, and not accompanied by meaty let alone bloated midbass is a hell of a bad search. Shuoer Tape is such a truffle. And a tasty one at that – although miles from a widely applicable tool like T4 is, rightly due to its specialties.
Take clarity, or better yet clear neutrality, as another example. Where do I find something really better on that? Until now, for me it took TIN P1. Which on the other hand is the epitome of the de-energetic, supremely-relaxing cuddler. Besides being “expensive” to amp.
Summarising, T4 is a really difficult to beat compromise in its applicative segment – in a budget price bracket or thereabout. A few (not many) other IEMs can do better at single sections, but if I only had space in the bag for just “one” IEM to overdecently cover the entire jazz spectrum, I would still probably choose T4.
Test setup

5N OFC and copper alloy single-ended cable (stock cable with TIN P1)
Nicehck 16 core High Purity Copper balance ended cable
Symbio Peel / T4 Stock white / JVC SpiralDot tips
Lossless 16/44.1 – 24/96 – 24/192 FLAC tracks.
Signature analysis
Tonality Fundamentally neutral, with some small concession to a modest midbass elevation and moderate treble bump; the latter being prevalent to the former, the end result is an overall “slightly bright-neutral” tonality, with a reciprocal calibration offering quite engaging dynamics.
Sub-Bass Flat compared to mid-bass, which means not elevated (but not rolled off either). Fast in its category, decently textured.
Mid Bass Very modestly elevated compared to a purely flat-neutral signature, just enough to offer a brushstroke of warmth, and some light bass tones to the presentation, always staying very far from bleeding in or even compromising mids clarity.
Mids Fast and clear are the words here. Mids are very well rendered overall, with special regards to the high part.
Male Vocals Bodied and natural. Warmed up (but not veiled) by the modest midbass elevation.
Female Vocals Crystal clear and as good as Males in quality, in some case female voices present sibilance to me. It goes away in two ways: either adopting appropriate tips (in my case JVC SpiralDot or Symbio Peel) and leaving T4s relatively shallow inserted, or fitting other tips allowing for a deeper insertion (in my case JVC Spiraldot or T4’s stock white tips work equivalently well for me). YMMV, as always.
Highs Averagely extended alhough very airy, clair, almost bright without being offensive. The obvious peak (positionable between 5 and 6KHz, depending on insertion) contributes to the overall crispness of this section, but comes accross as excessive some times and this is probably the sole real “con” in the entire presentation
Technicalities
Soundstage Above average, but no more than that. Width is just about out of my head.
Imaging Indeed, I’d call this more a well done stereo effect than a good 3D positioning. Imaging is therefore “average” in my books.
Details T4 offers more “clarity” than “details” per se. That said, perceived detail retrieval is not bad at all especially in this category. It honestly takes a more specialised IEM to do significantly better.
Instrument separation Overall clarity and neutrality is accompanied by very, very good layering and separation all over the entire spectrum
Driveability Good. A phone is way enough.
Physicals
Build Full metal, very solid housings, complemented with a quite stylish turbine-shaped engravure on the back side (it’s not a vent!). I never had any issues but quite a few users reported problems to the female MMCX connectors.
Fit The housings are not huge and cylindrical and as such they tend to be quite easy to fit, barred very small or uncommondly shaped conchas. They fit perfectly to me anyway. The nozzle not short, allowing for relatively deep insertion.
Comfort Extremely comfortable once properly fitting.
Isolation Especially when a realatively deep insertion is opted for, isolation is very good.
Cable While not a bad one electrically speaking (5N Silver-Plated Copper) my T4 stock cable miserably failed after a week (both male MMCX connectors gone). I must say the vendor promptly sent me a replacement, although not an impressive one either in terms of quality. Considering T4’s easy driveability, I’ve recently adopted P1’s very good (5N OFC and copper alloy) but single-ended stock cable on it, and I’m quite happy of the pairing.

Cons: They are too neutral, not exciting in any way.
There is a slight peak somewhere in the lower treble.
Bad sound placement.
It's just left-right, I don't know what they've done, but it's just absolutely the worst I've heard.
I can tell that something is somewhere left, right, or center, but I can't tell where exactly.
As if something's happening with the phase, but phase tests don't show anything, so it's not a faulty unit that was wired incorrectly.

Would've been 4.0/5.0 if they didn't fail with imaging that bad.

Introduction
TinHiFi is a brand, established in the province of Guangdong (China), which was launched in 2017. Its philosophy is to offer HiFi sound and the best quality, at the best price. To this end, they strive to ensure that high quality music is not a luxury, but the norm. Since then, they have released several IEMS (T2 Pro, T3, P1, T2 Plus, even a TWS, the TWS2000).
The model I'm currently reviewing is the T4. They are IEMS which price is around $99, which is equipped with a 10mm dynamic driver, with CNT diaphragm. It has been manufactured in aluminum, aerospace grade, which combines elements of automotive design and high-end aircraft.
Specifications
Packaging
The T4 comes in a sober black box, measuring 182x137x51mm, in the centre of which the brand logo, in gold relief, stands out. On the bottom, in a dark green colour, almost imperceptible, it is possible to read the name of the model. On the side faces, top and bottom, is the model in white, while on the right and left faces, one can read the name of the brand. On the back side there are barcodes, QR and certifications. After lifting the lid of the box, it is possible to see the two capsules, with some white tips, red core, on. Both are strongly protected by a dense foam mold. The moulded part where they rest can be removed and underneath it there is a black cardboard box, an instruction booklet and a guarantee card. In the lower half of the box, a large light brown leather box, embedded in another black mould, stands out enormously. Inside the little black box, there are the rest of the items. In short:
The packaging is plain, very functional, simple, well-structured. The transport box is formidable, one of the best in its range, very elegant, as well as practical. Perhaps its size is a bit large, more on the outside than on the inside. The accessories, two pairs of tips and a pair of foam, fit the standard within the price, fair and adequate. The cable looks quite premium, with high quality connectors, too bad the plastic coating is too rigid.
Construction and Design
The capsules have a double cylinder design, coupled at 90º, at their rear. In detail, the body of the IEM is a thick cylinder of 12mm diameter and 18mm total length. At its rear there is another cylinder, attached to a ring at 90º, which surrounds the capsule. Inside, the MMCX connector is embedded, plated on another one. At the base of each connector, there is a plastic washer, red or blue, which identifies each channel. At the very centre of the junction between the connector cylinder and the ring, there is a hole. Above it, in the same vertical, at the base of the nozzles, there is another hole. They are located on a rounded base and have a length of approximately 3.5mm. The smallest diameter is 5.4mm and the outer ring is 6mm. Inside there is a dense metal grid. The rear face is formed by a multitude of radial grooves, like a car wheel.
The capsule construction is quite solid, mixing aerospace grade aluminum, along with a stainless steel casing. Its size is not very big and its weight is less than it seems, at first sight.
The cable has generous metal connectors. The plug housing is large, cylindrical, straight, with roughened rings on each side to improve grip. The piece divides a smooth, metallic cylinder, with the logo inscribed in white ink. The pin is a transparent plastic ball. The sleeves of the MMCX connectors are metal cylinders with two slots on the back. They have the letters R and L painted in white, to identify the channel. All the connectors are gold-plated. The cable is made of high purity copper, silver plated and consists of two strands of 1.5mm each. They are covered with a transparent, somewhat rigid plastic and, in spite of the fact that they are braided, the cable is not very flexible and has a slight memory effect, which spoils the whole. Finally, near the plug, there is a velcro band, in grey, with the logo of the brand in white, to collect the cable.
Despite the fact that the capsules are cylindrical, the 90º connector gives it a different design. The surfaces are highly polished and shiny. The MMCX connector fits a bit tightly and the cable does not rotate too much inside. But both connections feel secure. The cable is very much in line with the design of the capsules, but its plastic coating does not give it the best flexibility, so it is totally comfortable.
Adjustment and Ergonomics
The capsules, although the connector cylinder is a 90º piece, are of a classic cylindrical design. Thus, the ergonomics are quite simple. The design has taken care that these connectors do not disturb or rub against the rest of the ear parts, at least in my case. I can rotate the capsules at will, to find the best insertion, which, on the other hand, is quite straight. Ergonomically speaking, there is no greater fitting than direct insertion, which can limit their coupling, depending on one's morphology. In my case, I consider that I have quite normal ears and I have hardly any problems with IEMS. With the T4, neither and this means that I find their adjustment simple and comfortable. The cable over the ear does not bother and barely rubs, hanging quite free and imperceptible. The best fit will depend on the tips used, as IEMS don't hold up anywhere. The insertion is superficial, and bi or tri-flange tips can be used for deeper insertion, but the straight design may not be the most appropriate for this type of insertion, although everything is tested, depending on the morphology of each.
Sound
Profile
The Tin HiFi T4 are IEMS with a very slightly warm character, within a balanced profile, with an analytical tendency. The lower part stands out in the middle and the warmth is noticeable in the projection of the initial part of the mids. My unit, feels balanced in the upper mids, being very clear and sharp, but never unpleasant. The upper zone is detailed, resolving and pleasant. I find that the three bands have a good harmony and that one can enjoy each one of them, without interference from one band to the other.
Bass
The lower zone of the T4 has a presence that is somewhat superior to neutral, without ever entering into bass territory. I think that Tin HiFi has educated the lower zone to recreate beauty, achieving a slight emphasis on its central zone, which brings depth and an exciting touch to the music. Its texture is soft, yet vibrant, with a faintly warm color and very well executed. Its decay is fast and it is harmless to the rest of the frequencies. The sub-bass, does not have as much presence as I would have liked, but its sonority is never forced, but is very natural and perceptible. The bass is executed fast and tight. The descriptive capacity of the low zone, is in charge of providing a tonal musicality to the bass, which makes them very melodious and pleasant. So much so, that a greater amount of emphasis and notoriety is missed, something that would have finished off the area in an excellent manner.
Mids
The search for beauty continues its journey in the central zone, finding, in this range, the gateway to the area closest to its goal. Swimming in a sea of clarity, cleanliness is revealed from the beginning of the mid-range, accompanied by a tenuous transient warmth, which bids farewell when the mids reaches its zenith. Voices sail subtly, blending between the fullness of its width and the absence of a more vigorous and deeper body. They feel present and close, their texture is smooth and harmonious, but they do not feel so rounded, as they are not very energetic or corpulent. The analytical tendency of this area, builds the voices in a detailed way, wide, although somewhat flat. The cleanliness of its execution, is its strong point and it is there where the beauty of its recreation lies, generating a sensation of height and superior origin, that wraps the instruments, as if it was a light and transparent mantle. Similarly, the instruments are reproduced with the same feeling of delicacy and finesse. Although, on this occasion, many of them require something more powerful than just a high-resolution sketch, which lacks a greater packaging. In this sense, the central area suffers from sufficient flesh, and does not give the range greater volume and a more exuberant presence. Instead, all that absence becomes definition and transparency, revealing the true analytical pulse of the midrange.
Treble
I think the treble is quite attractive, being slightly bright and expressive in its first half, standing out in presence, but not reaching fatigue, measuring its edges at the right point. In this way, the first flashes are very fine and very well defined, giving the sound that analytic quality, beyond neutrality. The delicacy is not lost, nor is its beauty disfigured, only a slight descent is appreciated in the continuation, necessary to limit sibilances and to avoid fatigue after a long use. Despite this, transparency never disappears and stands as another great virtue of the T4. The amount of detail is unquestionable, but, at the micro level, a simply good resolution capacity is perceived, which is not capable of revealing the best kept secrets. Finally, the amount of air is quite moderate, appreciable, but without being decisive within the overall sound.
Soundstage, Separation
Despite the good work of the lower zone, neutrality has a greater weight when it comes to recreating the scene. In this way, it is drawn wider than it is deep, with good separation and that characteristic height of its sound. The distance is quite good, in that horizontal coordinate, but it is perceived as somewhat limited between planes. In this way, the instrumental recreation has a good positioning and good silence around it, but it does not transcend in depth, nor in three-dimensional generation. That is why the scene is perceived frontally, panoramic and slightly curved, but not completely involving.
Comparisons
NF Audio NA2
NA2s are more polarized IEMS than T4s, with a more V-shaped profile. Both their lower and upper-middle zones are more emphasized. The sound pressure of the bass is more impressive, the sub-bass is perceived deeper, with a longer body, somewhat slower. Meanwhile, the T4, do not have so much sub-bass, but have a very successful texture, which borders the mid-bass frequencies, drawing them with a very evocative buzz. In the mid zone, the NA2 have more body, something that can be noticed in the male voices and in the remarkable instruments of this part. The lower-mid range acquires a fuller presence, while the T4 sounds flatter, smoother and cooler, with less emotion. However, they have better balance and poise, while the NA2s feel more extreme. Even the greater presence in the upper range of the mids makes them more persistent, comparatively speaking, where T4s are more delicate, less intense, but softer and more homogeneous. On the other hand, this greater linearity of the midrange, in the T4, provides a slight sensation of hollowness, where the NA2 offers a more complete and rounded experience, despite the greater sinking of its central zone.
In the upper part, the sonority is somewhat different between the two. The T4s have more defined, fine and delicate highs. While the NA2 are somewhat harder and wider, while more incisive. In the T4, its initial extension is longer, being perceived more natural and complete. The details sound better in T4, due to its better resolution, but it is also true that the NA2 has more air, something that helps it generate a wider scene, while deep and more three-dimensional, with a greater level of separation.
In the construction section, the differences are clear: the T4 are metallic and cylindrical, the NA2 are polycarbonate, with a semi-custom shape, which barely weigh. The cable is thicker and seems to be of higher quality in the T4, although it is somewhat more uncomfortable. The ergonomics are somewhat better in the NA2, due to the weight and fit, but the difference in this aspect is not relevant, as is the packaging and level of accessories.
In short, more than rivals, both IEMS could be, almost, complementary.
TFZ No.3
The No.3s are old-fashioned rockers who are still alive, thanks to the house brand sound, TFZ, where the bass rules. And, of course, it's in the low end that the differences begin. The TFZ bass is strong, deep, slightly slower and wider and more powerful, with a strong sub-bass, a rough and pleasant texture, able to satisfy the fans of the area. On the other hand, the low range of the T4, is not so complete, but it still has a very precise and pleasant texture, besides being faster, clear, precise, defined and clean.
The middle zone, in the T4, retains its classic homogeneity, while the TFZ polarizes this range. Again, the cooler timbre is perceived in the T4, which is noticeable in the voices, which seem to be pushed upwards, while the TFZ plays them from below, with a greater sense of depth and fullness. In these voices, the T4s show finesse and final details, but their reproduction is flatter, smoother and less suggestive. The upper mids are very different, starting from that polarization I was talking about earlier, in No.3. They have much more energy, due to their more U-V profile, which exerts an important power, providing the sound with more dynamics, but also with a more forceful and, certainly, hard character. The T4, are more muted, comparatively, due to that balance of theirs, which prevents them from going out of their own script.
In the sonority of the treble, the differences persist. In the T4 they sound wider, softer, relaxed and more delicate. In the No.3, they are more aggressive, but also more crisp. Overall, the No.3s have a higher pitched sound and also, with more bass, due to their U-V profile. The T4s are more balanced. The representation of detail is another point: No.3s sound more incisive and present, while T4s sound dimmer and less bright, but are not omitted.
The scene is wider in T4, but has less depth. In the TFZ, it's more compact, but deeper. The lateral separation is greater in the T4, however, more three-dimensional in the No.3, while in the T4, the music is recreated flatter.
There are clear differences in the construction: metal vs plastic in the capsules, cylindrical vs semi-custom shape. The cable has similar connectors, being thicker in the T4, but equally rigid in both models. Better accessories in the T4, with a very superior box, as opposed to a too simple bag, with the same number of silicone tips. Although the T4, provides a couple of foam tips. The presentation of the packaging is superior in the T4, being more careful and eye-catching.
Conclusion
The T4 has been my first Tin HiFi and, after reading a lot about them and about the brand itself, it has been an excellent start. From them, I must emphasize the sound generated with its dynamic, analytical, very descriptive, detailed, bright, clear and transparent driver, without losing sight of the quality in the recreation of the lower area. Without a doubt, it is an explicit, neutral sound, with a somewhat cold tendency, which I like and which allows me to enjoy many details and its richness of nuances. But it's not just the sound that's good, the design, construction, ergonomics and packaging are up to, even above, its price. Considering its profile, I consider the T4 to be a counterpoint to the classic sound coming from a dynamic driver, which every enthusiast should try.

The capsules have a double cylinder design, coupled at 90º, at their rear. In detail, the body of the IEM is a thick cylinder of 12mm diameter and 18mm total length. At its rear there is another cylinder, attached to a ring at 90º, which surrounds the capsule. Inside, the MMCX connector is embedded, plated on another one. At the base of each connector, there is a plastic washer, red or blue, which identifies each channel. At the very centre of the junction between the connector cylinder and the ring, there is a hole. Above it, in the same vertical, at the base of the nozzles, there is another hole. They are located on a rounded base and have a length of approximately 3.5mm. The smallest diameter is 5.4mm and the outer ring is 6mm. Inside there is a dense metal grid. The rear face is formed by a multitude of radial grooves, like a car wheel.
The capsule construction is quite solid, mixing aerospace grade aluminum, along with a stainless steel casing. Its size is not very big and its weight is less than it seems, at first sight.
The cable has generous metal connectors. The plug housing is large, cylindrical, straight, with roughened rings on each side to improve grip. The piece divides a smooth, metallic cylinder, with the logo inscribed in white ink. The pin is a transparent plastic ball. The sleeves of the MMCX connectors are metal cylinders with two slots on the back. They have the letters R and L painted in white, to identify the channel. All the connectors are gold-plated. The cable is made of high purity copper, silver plated and consists of two strands of 1.5mm each. They are covered with a transparent, somewhat rigid plastic and, in spite of the fact that they are braided, the cable is not very flexible and has a slight memory effect, which spoils the whole. Finally, near the plug, there is a velcro band, in grey, with the logo of the brand in white, to collect the cable.
Despite the fact that the capsules are cylindrical, the 90º connector gives it a different design. The surfaces are highly polished and shiny. The MMCX connector fits a bit tightly and the cable does not rotate too much inside. But both connections feel secure. The cable is very much in line with the design of the capsules, but its plastic coating does not give it the best flexibility, so it is totally comfortable.
Adjustment and Ergonomics
The capsules, although the connector cylinder is a 90º piece, are of a classic cylindrical design. Thus, the ergonomics are quite simple. The design has taken care that these connectors do not disturb or rub against the rest of the ear parts, at least in my case. I can rotate the capsules at will, to find the best insertion, which, on the other hand, is quite straight. Ergonomically speaking, there is no greater fitting than direct insertion, which can limit their coupling, depending on one's morphology. In my case, I consider that I have quite normal ears and I have hardly any problems with IEMS. With the T4, neither and this means that I find their adjustment simple and comfortable. The cable over the ear does not bother and barely rubs, hanging quite free and imperceptible. The best fit will depend on the tips used, as IEMS don't hold up anywhere. The insertion is superficial, and bi or tri-flange tips can be used for deeper insertion, but the straight design may not be the most appropriate for this type of insertion, although everything is tested, depending on the morphology of each.
Sound
Profile
The Tin HiFi T4 are IEMS with a very slightly warm character, within a balanced profile, with an analytical tendency. The lower part stands out in the middle and the warmth is noticeable in the projection of the initial part of the mids. My unit, feels balanced in the upper mids, being very clear and sharp, but never unpleasant. The upper zone is detailed, resolving and pleasant. I find that the three bands have a good harmony and that one can enjoy each one of them, without interference from one band to the other.
Bass
The lower zone of the T4 has a presence that is somewhat superior to neutral, without ever entering into bass territory. I think that Tin HiFi has educated the lower zone to recreate beauty, achieving a slight emphasis on its central zone, which brings depth and an exciting touch to the music. Its texture is soft, yet vibrant, with a faintly warm color and very well executed. Its decay is fast and it is harmless to the rest of the frequencies. The sub-bass, does not have as much presence as I would have liked, but its sonority is never forced, but is very natural and perceptible. The bass is executed fast and tight. The descriptive capacity of the low zone, is in charge of providing a tonal musicality to the bass, which makes them very melodious and pleasant. So much so, that a greater amount of emphasis and notoriety is missed, something that would have finished off the area in an excellent manner.
Mids
The search for beauty continues its journey in the central zone, finding, in this range, the gateway to the area closest to its goal. Swimming in a sea of clarity, cleanliness is revealed from the beginning of the mid-range, accompanied by a tenuous transient warmth, which bids farewell when the mids reaches its zenith. Voices sail subtly, blending between the fullness of its width and the absence of a more vigorous and deeper body. They feel present and close, their texture is smooth and harmonious, but they do not feel so rounded, as they are not very energetic or corpulent. The analytical tendency of this area, builds the voices in a detailed way, wide, although somewhat flat. The cleanliness of its execution, is its strong point and it is there where the beauty of its recreation lies, generating a sensation of height and superior origin, that wraps the instruments, as if it was a light and transparent mantle. Similarly, the instruments are reproduced with the same feeling of delicacy and finesse. Although, on this occasion, many of them require something more powerful than just a high-resolution sketch, which lacks a greater packaging. In this sense, the central area suffers from sufficient flesh, and does not give the range greater volume and a more exuberant presence. Instead, all that absence becomes definition and transparency, revealing the true analytical pulse of the midrange.
Treble
I think the treble is quite attractive, being slightly bright and expressive in its first half, standing out in presence, but not reaching fatigue, measuring its edges at the right point. In this way, the first flashes are very fine and very well defined, giving the sound that analytic quality, beyond neutrality. The delicacy is not lost, nor is its beauty disfigured, only a slight descent is appreciated in the continuation, necessary to limit sibilances and to avoid fatigue after a long use. Despite this, transparency never disappears and stands as another great virtue of the T4. The amount of detail is unquestionable, but, at the micro level, a simply good resolution capacity is perceived, which is not capable of revealing the best kept secrets. Finally, the amount of air is quite moderate, appreciable, but without being decisive within the overall sound.
Soundstage, Separation
Despite the good work of the lower zone, neutrality has a greater weight when it comes to recreating the scene. In this way, it is drawn wider than it is deep, with good separation and that characteristic height of its sound. The distance is quite good, in that horizontal coordinate, but it is perceived as somewhat limited between planes. In this way, the instrumental recreation has a good positioning and good silence around it, but it does not transcend in depth, nor in three-dimensional generation. That is why the scene is perceived frontally, panoramic and slightly curved, but not completely involving.
Comparisons
NF Audio NA2
NA2s are more polarized IEMS than T4s, with a more V-shaped profile. Both their lower and upper-middle zones are more emphasized. The sound pressure of the bass is more impressive, the sub-bass is perceived deeper, with a longer body, somewhat slower. Meanwhile, the T4, do not have so much sub-bass, but have a very successful texture, which borders the mid-bass frequencies, drawing them with a very evocative buzz. In the mid zone, the NA2 have more body, something that can be noticed in the male voices and in the remarkable instruments of this part. The lower-mid range acquires a fuller presence, while the T4 sounds flatter, smoother and cooler, with less emotion. However, they have better balance and poise, while the NA2s feel more extreme. Even the greater presence in the upper range of the mids makes them more persistent, comparatively speaking, where T4s are more delicate, less intense, but softer and more homogeneous. On the other hand, this greater linearity of the midrange, in the T4, provides a slight sensation of hollowness, where the NA2 offers a more complete and rounded experience, despite the greater sinking of its central zone.
In the upper part, the sonority is somewhat different between the two. The T4s have more defined, fine and delicate highs. While the NA2 are somewhat harder and wider, while more incisive. In the T4, its initial extension is longer, being perceived more natural and complete. The details sound better in T4, due to its better resolution, but it is also true that the NA2 has more air, something that helps it generate a wider scene, while deep and more three-dimensional, with a greater level of separation.
In the construction section, the differences are clear: the T4 are metallic and cylindrical, the NA2 are polycarbonate, with a semi-custom shape, which barely weigh. The cable is thicker and seems to be of higher quality in the T4, although it is somewhat more uncomfortable. The ergonomics are somewhat better in the NA2, due to the weight and fit, but the difference in this aspect is not relevant, as is the packaging and level of accessories.
In short, more than rivals, both IEMS could be, almost, complementary.
TFZ No.3
The No.3s are old-fashioned rockers who are still alive, thanks to the house brand sound, TFZ, where the bass rules. And, of course, it's in the low end that the differences begin. The TFZ bass is strong, deep, slightly slower and wider and more powerful, with a strong sub-bass, a rough and pleasant texture, able to satisfy the fans of the area. On the other hand, the low range of the T4, is not so complete, but it still has a very precise and pleasant texture, besides being faster, clear, precise, defined and clean.
The middle zone, in the T4, retains its classic homogeneity, while the TFZ polarizes this range. Again, the cooler timbre is perceived in the T4, which is noticeable in the voices, which seem to be pushed upwards, while the TFZ plays them from below, with a greater sense of depth and fullness. In these voices, the T4s show finesse and final details, but their reproduction is flatter, smoother and less suggestive. The upper mids are very different, starting from that polarization I was talking about earlier, in No.3. They have much more energy, due to their more U-V profile, which exerts an important power, providing the sound with more dynamics, but also with a more forceful and, certainly, hard character. The T4, are more muted, comparatively, due to that balance of theirs, which prevents them from going out of their own script.
In the sonority of the treble, the differences persist. In the T4 they sound wider, softer, relaxed and more delicate. In the No.3, they are more aggressive, but also more crisp. Overall, the No.3s have a higher pitched sound and also, with more bass, due to their U-V profile. The T4s are more balanced. The representation of detail is another point: No.3s sound more incisive and present, while T4s sound dimmer and less bright, but are not omitted.
The scene is wider in T4, but has less depth. In the TFZ, it's more compact, but deeper. The lateral separation is greater in the T4, however, more three-dimensional in the No.3, while in the T4, the music is recreated flatter.
There are clear differences in the construction: metal vs plastic in the capsules, cylindrical vs semi-custom shape. The cable has similar connectors, being thicker in the T4, but equally rigid in both models. Better accessories in the T4, with a very superior box, as opposed to a too simple bag, with the same number of silicone tips. Although the T4, provides a couple of foam tips. The presentation of the packaging is superior in the T4, being more careful and eye-catching.
Conclusion
The T4 has been my first Tin HiFi and, after reading a lot about them and about the brand itself, it has been an excellent start. From them, I must emphasize the sound generated with its dynamic, analytical, very descriptive, detailed, bright, clear and transparent driver, without losing sight of the quality in the recreation of the lower area. Without a doubt, it is an explicit, neutral sound, with a somewhat cold tendency, which I like and which allows me to enjoy many details and its richness of nuances. But it's not just the sound that's good, the design, construction, ergonomics and packaging are up to, even above, its price. Considering its profile, I consider the T4 to be a counterpoint to the classic sound coming from a dynamic driver, which every enthusiast should try.

Greetings!
Today we’re checking out another new release from Tin HiFi, the T4.
Back in 2017, a great sounding earphone was released on the world. That earphone was the TinAudio T2. Despite receiving almost unanimously positive feedback, it flew under the radar until a few key hypsters got their hands on it. It has since become a staple recommendation to anyone wanting a well-built, neutral-leaning earphone for under 100 USD. Tin did not rest on their laurels and over the years have developed a handful of excellent followups like the single dynamic T1 and the planar magnetic P1. They rebranded to Tin HiFi, and have become one of the more highly respected Chinese hifi brands.
The T4 is the fifth earphone in the T Series and the culmination of everything Tin HiFi has learned from their past products. Is the T4 yet another outstanding release from Tin HiFi? Yes it is. Let’s look at why, shall we?
What I Hear I’ve been a big fan of Tin HiFi since the original T2 was released. It had a near-neutral signature that was a rarity for the price. The use of dual dynamics was also somewhat of a novelty since at the time, hybrids were still dominating the new release market. The T4 continues the Tin HiFi trend of neutral-bright signatures, but with only a single 10mm dynamic driver powering each side. The use of a carbon nanotube coating is kinda old school too since that was at it’s peak popularity in the early to mid 2010s.
Treble out of the T4 is light and sparkly with plenty of real detail, not just perceived detail because of some elevation in the brilliance region. That said, it has still been dialed back compared to earlier models like the T2 Pro, T3, and P1, and focus resides mostly in the lower treble. When combined with the improved low end performance that we’ll get to later, this makes the T4 the most balanced earphone in Tin’s lineup imo. Notes are lean with tons of air and space between them. This lightness translates into something that feels very nimble and well-controlled, regardless of how busy a track may get, and as such gives the T4 a very snappy presentation. Decay is maybe too quick. Not necessarily accurate, but it results in some impressive technical handling. While I know the treble here will bother some, I find it surprisingly non-fatiguing.
Like its predecessors, the T4 has pretty spectacular mids. They are forward, balanced and linear, have reasonably accurate timbre, and are technically capable. Female vocals turn out slightly cooler than I prefer, but are consistent in presentation with male vocals so neither ends up benefiting more from the T4’s style of tune. Clarity and detail are both above average with the T4 pulling the slightest nuances forward. It’s reasonably analytic, but not tiring in the process. As noted, timbre is fairly accurate but ends up making instruments sound slightly brighter than is correct. Still, it works in the context of the overall tune and minimal warmth injected into the overall sound presentation.
Bass is the aspect of the T4 I’m most impressed with when comparing to past Tin HiFi earphones. Extension is excellent and while sub-bass isn’t strongly emphasized and doesn’t overwhelm, it still gives off a proper rumble. Midbass is lean but extremely detailed and well-textured. It is fairly punchy for the most part, only occasionally lacking impact. It is very fast too and never drags it’s feet on rapid basslines, resulting in some of the most articulate and well-defined bass I’ve heard from in a single dynamic. Texture and detail is another positive, with the sort of grungy, low-res basslines your hear in tracks by The Prodigy and Malibu Ken coming out as offensively trashy as they’re supposed to.
When it comes to soundstage and related abilities, the T4’s weaknesses show. The soundstage itself is satisfyingly large with songs playing just around your head by default. Effects are effectively tossed off into the distance thanks to the width available. Depth is a bit more on the average side. More than workable since tracks still sound layered and there are no issues with instruments and effects blending together and losing their separation. But alas, now we come to imaging. This is where the T4 is a let down. While sound unquestionably moves from channel to channel, the process lacks precision and definition. Sounds sort of fade from one channel while becoming louder in the other, but without the impression of movement that usually accommodates that process. This was painfully obvious listening to BT’s ethereal “If The Stars Are Eternal Then So Are You And I”.
Imaging issues aside, this is to my ears the best earphone Tin HiFi has released to date. While it still retains the neutral-bright signature I have come to associate with the brand, brightness has been toned down and sub-bass improved both in terms of extension and emphasis. Where the T3 improved on everything I disliked about the T2 Pro, the T4 does a good job of tackling the T2s foibles.
Compared to a Peer (volumes matched with Dayton Audio iMM-6)
KB EAR Diamond (79.00 USD): Bass out of the T4 is notably less prominent, but slightly more impressive in my opinion. Like the Diamond it hits low notes with ease, but holds back the mid-bass and dials up the texture and speed. The T4’s driver gives off the impression of being exceptionally light and nimble, and feels like it runs circles around the Diamond when it comes to complex passages. That said, I can see the more weighty, thumpy presentation of the Diamond finding more fans because it’s a straight up more fun way to tune a low end. The T4’s mids are smoother and more refined. Upper and lower balance is improved benefiting both male and female vocals. Clarity is also a step up. Lastly, in my opinion, timbre also sounds more natural out of the T4. I was very surprised to find the T4 had less upper treble energy than the Diamond, with lower treble being similarly emphasized. Normally that would put the Diamond right into my preference crosshairs, but the midbass ends up being too distracting. The T4 also has better note control and is free of the slight splashiness present in the Diamond. Lastly, sound stage sits firmly in the T4’s favour with it being much more spacious all around. However, it has vague imaging with limited channel to channel differentiation that doesn’t hold a candle to the Diamond. Layering and separation are more in line though.
The T4 is definitely my preferred listen of the two thanks to it’s more balanced tune and all the extra detail it provides. Can’t help but be disappointed by the imaging though which the Diamond does much, much better.
In terms of build, the T4 is smaller, lighter, doesn’t isolate as well, is less comfortable, and has better fit and finish. I think the Diamond has a more appealing design though, and feels like the more premium product. A big part of that is the cable. The T4’s cable sucks. It is sticky, bouncy, and the loose braid is sloppy and gives the impression of cost cutting. Very similar to the P1’s cable, but worse due to the stickiness. Bleh…
Moondrop Starfield (109.00 USD): Bass on the Starfield is a little heavier and warmer with similar extension. The T4 is more textured and faster handling rapid notes even better, but like the Starfield can lack impact at times. The T4’s midrange is more forward with more upper mid emphasis. It has a cooler tonality and less accurate timbre as a result. Clarity and detail are similar with the T4 having a very slight edge. While neither earphone adds sibilance to a track, it’s more prominent through the T4. Overall a much less forgiving midrange than the Starfields is. Treble out of the T4 is more prominent from lower to upper giving it’s presentation extra energy and sparkle. Attack and decay are snappier than they are out of the Starfield giving it a more analytic feel. Sound stage is pretty even between the two with the Starfield’s less forward mids giving the impression of a more distant and rounded stage. The T4 can toss effects further away despite a more intimate starting point. Imaging is notably more nuanced out of the Starfield while both provide excellent layering and separation.
I’ll give the Starfield a slight edge in overall sound quality due to the T4’s mediocre imaging, but otherwise they trade blow for blow and are both outstanding earphones. Go with the T4 if you like a more neutral leaning sound, and the Starfield if you prefer some extra low end and general warmth.
In terms of build, both are great. The T4’s design isn’t as eye catching but fit and finish is better, and since it features bare metal, you won’t have to worry about paint chips as seems to be an issue for some with the Starfield. While I like MMCX connectors, the T4’s have too much play and feel nowhere near as secure as the Starfield’s excellent recessed 0.78mm 2-pin ports. The Starfield’s cable is also nicer.
While the T4’s cable is thicker and has a nice chin cinch, it’s also quite bouncy and sticky. The Starfield’s cable is light and lean and rarely gets in the way. Both have well-designed preformed ear guides.
In The Ear Modern earphones have really stepped things up in the build quality game. There are sub-20 USD earphones out there with full metal shells and a level of fit and finish that pretty easily shame pricier gear, without resorting to a generic design or shell that is shared with various other brands and products (see BGVP YSP04). The T4 is a good example of this with bare, polished aluminum shells that have taken inspiration from automotive and aviation realms. Fit and finish is excellent with a design that incorporates seams in a way that they are naturally hidden. My only complaint about the build centres around the MMCX ports. With the cable connected, there is a fair bit of play and I worry about longevity. I’d be totally okay with Tin HiFi moving over to a 2-pin design for future products.
Well, I guess I can complain about the cable too. In my opinion it’s a big step back for the brand. While it features quality materials, the sheath is loosely wound like it was on the P1. It makes the cable look somewhat sloppy and feels like they cut some corners to save on manufacturing costs since there is quite a bit less material being uses. The sheath is also quite bouncy AND sticky. The worst of all worlds really. Outside of the nice metal hardware, useful chin cinch, and well-formed ear guides, there isn’t much I like about this cable at all.
Even though the general barrel-like shape of the earphone doesn’t stray far from other models in the T Series, Tin HiFi did make at least one major change that improves the overall wearing experience, and that is their use of aluminum. The T4 is light. Almost worryingly so upon first grasp. When I took them out of the package for the first time the feathery weight came as a shock compared to its predecessors. It felt kinda cheap to be honest. However, pull out a past T Series model and you find that the T4 is just as solid, though the latter model’s matte finish is more appealing in my opinion. The turbofan texturing on the back adds some cool factor missing from the notably more plain T2, and to a lesser extent the T3 as well. Back to the point; the low weight combined with very similar ergonomics to the T2 and T3 fixes some of the stability issues with those models. The T4 is still somewhat reliant on your tip choice for a consistent and reliable seal that isn’t affected by movement, just not to the extent of past models.
Isolation is below average, which could be attributed to the ample ventilation and shallow fit. I’m guessing the aluminum shells are quite thin too, a decision that would help keep the weight as low as it is. Using them as earplugs with no music playing, I can go about my day more or less normally, only having to remove the earphones once in a while to hear something I missed. Tossing on foam tips helps, but still doesn’t make the T4 suitable for use in very noisy areas. With music playing things fare better, but I still wouldn’t be inclined to pick these up for a bus ride. A study session at the library or walk through the park would be more appropriate.
In The Box In the past Tin HiFi has shipped their earphones in some pretty unique packages. The blue book-like cases that came with the T2, T2 Pro, and T3 were like nothing else on the market. The T4’s packaging is nice, no doubt, but isn’t anything we haven’t seen elsewhere.
The matte black box has Tin HiFi and T4 branding and model information printed on the front in gold lettering, while various Tin HiFi logos can be found in white around the sides. Lifting off the lid you’re greeted to the T4 ear pieces set within a foam insert, with a snazzy new leatherette case down a little further. Lifting out the upper foam insert reveals a slew of tips. In all you get:
Final Thoughts Let’s get the bad out of the way first; imaging quality is sorely lacking, the cable needs to be replaced asap, and isolation is minimal at best. Other than that, the T4 is amazing. The light weight aluminum housings improve fit over the similarly shaped T2 and T3, and the turbofan inspired backing looks pretty slick. While the general signature follows the Tin HiFi trend of neutral-bright, upper treble has been toned down and lower bass enhanced. Detail and clarity are above average for the segment. All of this results in what I think is one of the most balanced and capable earphone in their lineup.
Nicely done yet again Tin HiFi, and thanks for reading!

The T4 was easy to drive so there is no need for an amp, HOWEVER, tossing it on something more capable than a basic phone or DAP did help VERY slightly with imaging.

The T4 also has better note control and is free of the slight splashiness present in the Diamond. Lastly, sound stage sits firmly in the T4’s favour with it being much more spacious all around. However, it has vague imaging with limited channel to channel differentiation that doesn’t hold a candle to the Diamond. Layering and separation are more in line though.
The T4 is definitely my preferred listen of the two thanks to it’s more balanced tune and all the extra detail it provides. Can’t help but be disappointed by the imaging though which the Diamond does much, much better.
In terms of build, the T4 is smaller, lighter, doesn’t isolate as well, is less comfortable, and has better fit and finish. I think the Diamond has a more appealing design though, and feels like the more premium product. A big part of that is the cable. The T4’s cable sucks. It is sticky, bouncy, and the loose braid is sloppy and gives the impression of cost cutting. Very similar to the P1’s cable, but worse due to the stickiness. Bleh…
Moondrop Starfield (109.00 USD): Bass on the Starfield is a little heavier and warmer with similar extension. The T4 is more textured and faster handling rapid notes even better, but like the Starfield can lack impact at times. The T4’s midrange is more forward with more upper mid emphasis. It has a cooler tonality and less accurate timbre as a result. Clarity and detail are similar with the T4 having a very slight edge. While neither earphone adds sibilance to a track, it’s more prominent through the T4. Overall a much less forgiving midrange than the Starfields is. Treble out of the T4 is more prominent from lower to upper giving it’s presentation extra energy and sparkle. Attack and decay are snappier than they are out of the Starfield giving it a more analytic feel. Sound stage is pretty even between the two with the Starfield’s less forward mids giving the impression of a more distant and rounded stage. The T4 can toss effects further away despite a more intimate starting point. Imaging is notably more nuanced out of the Starfield while both provide excellent layering and separation.
I’ll give the Starfield a slight edge in overall sound quality due to the T4’s mediocre imaging, but otherwise they trade blow for blow and are both outstanding earphones. Go with the T4 if you like a more neutral leaning sound, and the Starfield if you prefer some extra low end and general warmth.
In terms of build, both are great. The T4’s design isn’t as eye catching but fit and finish is better, and since it features bare metal, you won’t have to worry about paint chips as seems to be an issue for some with the Starfield. While I like MMCX connectors, the T4’s have too much play and feel nowhere near as secure as the Starfield’s excellent recessed 0.78mm 2-pin ports. The Starfield’s cable is also nicer.
While the T4’s cable is thicker and has a nice chin cinch, it’s also quite bouncy and sticky. The Starfield’s cable is light and lean and rarely gets in the way. Both have well-designed preformed ear guides.
In The Ear Modern earphones have really stepped things up in the build quality game. There are sub-20 USD earphones out there with full metal shells and a level of fit and finish that pretty easily shame pricier gear, without resorting to a generic design or shell that is shared with various other brands and products (see BGVP YSP04). The T4 is a good example of this with bare, polished aluminum shells that have taken inspiration from automotive and aviation realms. Fit and finish is excellent with a design that incorporates seams in a way that they are naturally hidden. My only complaint about the build centres around the MMCX ports. With the cable connected, there is a fair bit of play and I worry about longevity. I’d be totally okay with Tin HiFi moving over to a 2-pin design for future products.
Well, I guess I can complain about the cable too. In my opinion it’s a big step back for the brand. While it features quality materials, the sheath is loosely wound like it was on the P1. It makes the cable look somewhat sloppy and feels like they cut some corners to save on manufacturing costs since there is quite a bit less material being uses. The sheath is also quite bouncy AND sticky. The worst of all worlds really. Outside of the nice metal hardware, useful chin cinch, and well-formed ear guides, there isn’t much I like about this cable at all.
Even though the general barrel-like shape of the earphone doesn’t stray far from other models in the T Series, Tin HiFi did make at least one major change that improves the overall wearing experience, and that is their use of aluminum. The T4 is light. Almost worryingly so upon first grasp. When I took them out of the package for the first time the feathery weight came as a shock compared to its predecessors. It felt kinda cheap to be honest. However, pull out a past T Series model and you find that the T4 is just as solid, though the latter model’s matte finish is more appealing in my opinion. The turbofan texturing on the back adds some cool factor missing from the notably more plain T2, and to a lesser extent the T3 as well. Back to the point; the low weight combined with very similar ergonomics to the T2 and T3 fixes some of the stability issues with those models. The T4 is still somewhat reliant on your tip choice for a consistent and reliable seal that isn’t affected by movement, just not to the extent of past models.
Isolation is below average, which could be attributed to the ample ventilation and shallow fit. I’m guessing the aluminum shells are quite thin too, a decision that would help keep the weight as low as it is. Using them as earplugs with no music playing, I can go about my day more or less normally, only having to remove the earphones once in a while to hear something I missed. Tossing on foam tips helps, but still doesn’t make the T4 suitable for use in very noisy areas. With music playing things fare better, but I still wouldn’t be inclined to pick these up for a bus ride. A study session at the library or walk through the park would be more appropriate.
In The Box In the past Tin HiFi has shipped their earphones in some pretty unique packages. The blue book-like cases that came with the T2, T2 Pro, and T3 were like nothing else on the market. The T4’s packaging is nice, no doubt, but isn’t anything we haven’t seen elsewhere.
The matte black box has Tin HiFi and T4 branding and model information printed on the front in gold lettering, while various Tin HiFi logos can be found in white around the sides. Lifting off the lid you’re greeted to the T4 ear pieces set within a foam insert, with a snazzy new leatherette case down a little further. Lifting out the upper foam insert reveals a slew of tips. In all you get:
- T4 earphones
- Silver-plated MMCX cable (0.03/63C+200D enamelled wire*1C+0.08/28C silver-plated enamelled winding)
- Leatherette carrying case
- Foam tips (m)
- White single flange silicone tips (s/m/l)
- Grey single flange silicone tips (s/m/l)
Final Thoughts Let’s get the bad out of the way first; imaging quality is sorely lacking, the cable needs to be replaced asap, and isolation is minimal at best. Other than that, the T4 is amazing. The light weight aluminum housings improve fit over the similarly shaped T2 and T3, and the turbofan inspired backing looks pretty slick. While the general signature follows the Tin HiFi trend of neutral-bright, upper treble has been toned down and lower bass enhanced. Detail and clarity are above average for the segment. All of this results in what I think is one of the most balanced and capable earphone in their lineup.
Nicely done yet again Tin HiFi, and thanks for reading!

Disclaimer Thanks to Lillian with Linsoul audio for arranging a sample of the T4 for the purposes of review. The thoughts within this review are my subjective opinions based on nearly two months of time spent with the T4. They do not represent Linsoul, Tin HiFi, or any other entity. At the time of writing the T4 was retailing for 109.00 USD: https://www.linsoul.com/pages/tin-hifi-t4
Specifications
- Driver: 10mm Carbon Nanotube Dynamic Driver

Thank ya sir. When I posting the T2 Plus review I realized I never posted the T4 review here. Oops...

Great review. Thanks for your efforts. I love these iems. Recommended them to my son, and of course, they were insufficient in the low-end for a 25 year-old hip-hop/edm fan (I forgot. So sue me, I got free iems out of it.) He gave them to me, and for the $80 he paid, they are stellar. I don't listen to much bass-heavy music tho, so horses for courses I guess. These are my every day carry iems. Not as forgiving as the Arias, but more revealing, especially from the mids up. Bass is not huge in quantity, but it's tight and controlled. I think they would be a bargain at twice the price.

This review originally appeared on my blog: https://medium.com/10hztech/tin-t4-review-48092e6b6e9d
I’ll be blunt with this one: Tin T4 is something I cannot quite recommend for reasons other than its sonic quality (albeit the sound itself has its fair share of mishaps).
Many seemed to have adjusted to the fact that these IEMs will likely have poor build quality/Quality Control in general and thus certain issues are “fine” as long as they get good performance at a lower price. Unfortunately, this kind of mentality causes more harm than good in the long run. We should demand better for the nearly $100 one has to pay to get these. Increasing the price nearly 3 times over the original T2 and then having similar, if not worse quality control issues is unacceptable.
Note: the ratings given will be subjective to the price tier. I bought the Tin T4 from Amazon with my own funds. Disclaimer

Price, while reviewed: 99 euros
Build: The T4 has similar build to the previous T series of earphones with an all metal (aluminium) housing+nozzle and plastic color-coded rings for channel identification. The big change this year is the finish of the housing as it is shinier than ever.
The big issue, however, is the Quality Control. My unit had the wobbly cable that would often cut-off abruptly. A quick discussion across various forums/groups later it seems to have been a rather wide-spread issue. Tin Hifi/Linsoul (their distributor) did offer a replacement cable (as the issue was mostly on cable-side) but this whole ordeal doesn’t inspire much confidence in the T4’s long-term durability. I can’t speak for others, so I will rate the build quality as it was on the unit I received: rather poor, solely because of the wobbly mmcx connector. Moreover, some seemed to had the issue on the IEM side, which was even worse.
3/5
Accessories: The accessory set has been improving for Tin Hifi over the years and with the T4 they did address most of my complaints with the T3 packaging. There is now a nice, over-sized carrying case, an attractive SPC cable, and 7 pair of ear-tips (3 pairs of white and 3 pairs of black silicone tips, 1 pair of foam).
The case looks great but is rather impractical if you prefer to stash you IEMs inside your pocket. Apart from the cable-controversy, no complaints. That’s a big complain, however.
3.5/5
Comfort and Isolation: It’s the third generation (fourth, if you count the T2 Pro) in a row that Tin Hifi has opted for this awful shape for their T series IEMs. It’s the very definition of poor ergonomics. The IEMs don’t fit snugly, the shape necessitates a shallow fit and it’s not a comfortable experience overall. The IEMs don’t fall out of your ears for sure, but as long as they are there — it isn’t a pleasant feeling.
Isolation is above average, and can be made even better if you use the foam tips.
3/5
Now, about the sound.
The T4 houses a 10mm Carbon Nanotube (CNT) driver. The overall sound signature is very analytical with noticeable boosts in the upper-mids and lower-treble. Bass punch isn’t sacrificed, however, and that is a welcome departure from Tin Hifi’s tendency to completely butcher a fundamental part of the frequency range. The T4 somehow reminds me of Audio Technica M50X, and that spells trouble.
Bass: My biggest complaint with the previous T series IEMs have been their poor, or utter lack of bass. T4 rectifies that big time. Heck, it’s one of the better bass responses you can get within the price bracket. I personally like the overall linearity of it, as the bass doesn’t go through abrupt bumps and shifts from 200Hz down to 20Hz. The sub-bass rumble is very much present (depending on the track) and while it won’t punch you into submission, it won’t be missed either. Bass speed is pretty good for a dynamic-driver IEM, and can keep up with fast note changes. Rage Against the Machine’s Killing in the Name demonstrates that perfectly.
It is neutral-ish bass done right.
4.5/5
Mids: The mid-range is where my problems with the T4 start cropping up, but let’s get through the positives first.
This is a very detailed pair of IEMs. I actually can’t think of another IEM that can beat it in overall detail retrieval under $100, and many higher priced IEMs are left in its wake. The lower-mids are also pretty even-handed and baritone vocals come through fine.
Now, on to more pressing issues. The upper-mids are overly emphasized by about 10dB which makes them a bit too spicy in general. Depending on the track and the mastering, the female vocals can range between “clear” to “I don’t want to listen to this anymore”. Loreena McKennit’s Dante’s Prayer doesn’t sound overly wrong and won’t pose much problems. Then you move to Meg Myer’s Desire (NSFW) and the chorus section is just overdone. Also leading edges of guitar riffs can sound harsh.
4/5
Treble: What I find more problematic than the overdone 3KHz peak is the overzealous 6KHz peak in the treble region. The other virtues of the mid-range also applies here: abundance of details, good instrument separation. But the 6KHz peak (this can be anywhere between 5–6KHz, varies upon insertion depth) is a massive letdown.
The rest of the treble region is mostly reined in. There’s even good amount of upper-treble extension with a peak at around 12KHz that adds air into the mix. Cymbals sound crisp with proper shimmer, and transients are also well defined as can be heard in some of the cymbal-choke passages (or numerous electronic music if you’re into that, check this one out).
That 5–6KHz peak is one that I’m personally sensitive to, and if you have similar issues with emphasis in that presence region, the T4 will be very difficult to listen to for long periods.
3.5/5
Soundstage: Soundstage is below average, with an overall intimate presentation. It’s not as intimate as Tin Hifi’s infamous P1, but it’s definitely a downgrade over their age-old T2. Such a bummer.
2.5/5
Imaging: Imaging is yet another letdown. Spatial cues are hazy, and while left-right channel separation is excellent, the instrument placement is very flat with no discernible directionality apart from left and right. Central imaging is good, however.
3/5
Select Comparisons
vs KBEar Diamond ($70): Both these IEMs are single dynamic drivers, with the Diamond having a DLC coated PET diaphragm vs the CNT diaphragm on the T4.
The Diamond has a better accessory set and far better build quality and comfort. The sound signature is polar opposite: KBEar Diamond going for a dark, bassy tuning whereas the Tin T4 is magnifying every little detail. Sub-bass is more prominent on the Diamond whereas T4 got more punch in the mid-bass. Overall timbre is better on the Diamond as a whole, but the vocals are more up-front on the T4.
In terms of soundstage, Diamond is wider whereas T4 is more intimate. Both have subpar imaging with perhaps the Diamond very slightly edging out the T4.
Dark vs Bright. You probably know which you want already.
vs Moondrop Starfield ($109): The Starfield and T4 both share the CNT diaphragm driver. The Moondrop IEM is warm-neutral in tone, with a more boosted mid-bass that sounds bloated in comparison to the tight, punchy mid-bass on the T4. Sub-bass rumble is also more prominent on the T4 despite having lower bass quantity versus the Starfield.
Midrange has more agreeable tonality on the Starfield, with excellent male/female vocals and no shout or shrill. The midrange, however, lacks excitement and sounds bland in the end. In fact, Starfield’s overall signature can get too dull and doesn’t really do justice to many tracks with high level of dynamics. One of reasons for this dullness is the subdued treble that robs it off of dynamics. T4 meanwhile can portray the dynamics well but often exaggerates the upper-ranges heavily thus resulting in a more fatiguing listen vs the Starfield. Starfield imaging is as poor as the T4, and soundstage is just as shallow.
I personally don’t find the Starfield’s much impressive, as apart from midrange they aren’t really doing anything that well. They are a safe recommendation however as they don’t do anything particularly wrong either.
Too safe is boring though. T4 pulls out all stops to get you the details, so at least it’s doing something exceptional.
vs Final E3000 ($60): The Final IEM doesn’t have a detachable cable. If you don’t mind that cable — let’s talk.
Comfort goes squarely to the E3000, and accessories/isolation to Tin T4.
In terms of bass, E3000 sounds boomy and sloppy in comparison. The mids are more recessed vs the T4 and lacks the upper-mid emphasis so female vocals are not as on-your-face. Treble presence is more noticeable on the E3000 but not as emphasized as it’s on the T4. Detail retrieval is also firmly in T4’s grasp as E3000 is more of a relaxed, chill-out IEM than something that constantly screams for your attention.
So far, E3000 is outclassed, but it’s gonna hit back with a wider soundstage and instrument separation/imaging that’s way out of Tin T4’s league. Vocal and timbre is also E3000’s forte. Most of all, it’s the overall presentation that makes the E3000 a more enjoyable listen than the technically superior but tonally challenged T4.
E3000 is something I don’t want to stop listening to, whereas T4 is a struggle to listen for more than half an hour at a time.
Conclusion
If all you’re after is gobs of details and can ignore everything else — Tin T4 will be one of the, if not the best options under the $100 range, undoubtedly. You can however spend a bit extra and get the Etymotic ER2XR but they have their unique set of challenges (fit, for one). So in a traditional IEM shell, T4 is kind of a lone wolf. It’s a laundry list of trade-offs, but if you know this “technicality overload” is what you want — pay no heed to my cries of agony.
I cannot, however, ignore the build issues. Many can only afford one IEM at a time and expects durability or quality assurance to a degree. Tin T4 spectacularly fails at both of these fundamentals. The tuning itself is polarizing, as I find them too dry, too analytical and too… forgettable. Yes, I hear things that most others in this range can barely pick out, but the peaky treble and shouty upper-mids sap out all the joy I find in music.
So I look elsewhere. Letting go is part of the process after all.

Thanks for the effort. They might sound better when you get old. They sound great to my old and damaged ears, but by that time they will be shot if your impressions of the build quality is correct. I have never removed the stock cable due to the reports of a crappy mmcx connection, but they don't require the power of a balanced connection anyway. Bummer that your experience has been so different from mine. I enjoy them a lot. I've never heard iems over $500 though, so maybe I don't really know what good sounds like Good for my wallet. Cheers.

Tin Hifi (Chinese audio company) took the community by storm with the affordable Tin T2 which was praised for its sound quality given its price. Today, we will take a look at the Tin T4 which is currently the latest model in Tin Hifi’s Tx series, the oldest brother of the siblings (T2, T2pro, T3).

The packaging is simple and elegant. It comes in a black box branded Tin Hifi with a set of ear tips, a good pleather case, and the IEMs themselves. Pretty standard nowadays but the light brown pleather hard case, which I found pretty aesthetic, was a nice inclusion.
Build quality and Fit (Score: 8/10)
Alright let’s start with the good things first. The build material of the earbud is stainless steel which seems to be chromed and polished until it shines which I felt was quite fancy. The cable seems to also be designed to match well with the earpieces. The materials used are pretty nice and ear earpieces are well-made. However, I've only used these for a short period of time so I am unable to tell if they will stand the test of time or if there would be any MMCX connection issues.
Now for the not so good stuff. I felt that the unique design of the shell is uncomfortable for longer listening sessions. It might differ from person to person depending of your ear shape and size but, for shorter sessions I am fine with it.

Bass (Score: 7.5/10)
Sub-bass is rather good here, you can really feel the rumble and that deep oomph (coming from modern pop genres). Mid bass is textured enough and the overall the bass performance is decent. In general, bass hits are clean and impactful but not overpowering other parts, a good reference point for anyone that is looking for neutral signatures with slight bass boost to keep that energy going.
Mids (Score: 6.5/10)
Lower mids are clear and very detailed, and have a very pleasing presentation. It's less emphasized than the sub bass but I would feel that its natural or “normal” here, sounds pretty leveled with the bass so no complains here at all, well done. Upper midrange just sounds a bit more emphasized and sometimes I feel that there is a “glare” or feels shouty in this region? I felt tired after longer listening periods and its part of the reason why it sounds bright-neutral. Female vocals, trumpets and violins are really forward (some synths too) and it just gets tiring after a while. However, it does detail pretty well in general so... Some quirks here and there but generally good.
Treble (Score: 7/10)
There are some spikes that may cause some sibilance but might just be me with the s sounds since I’m quite sensitive to that region. There is some airiness to this unit and generally its very detailed and clean with very little or some parts that may sound splashy depending on the tracks you listening to. In general, It is pretty good except for some peaks that make it sound quite bright which is prominent in the T2, T2 pro and T3).
Overall Sound and Comparison to the Tin T2s
Sound stage and imaging wise I would say it fares slightly above average in my opinion so minimally, you can expect some form of staging here so not entirely null in that area. Tonality wise its rather balanced and clean which is quite like the T2s but slightly better. Overall, I would say this is a decent step up from the T2 if you enjoy its signature but it costs twice as much hence some may argue that the T2 has more value. The T4 definitely holds its ground against other offerings as one that is cleaner and more sterile. This is relatively unique in its class right now so if you want something that is balanced, detail-oriented and somewhat neutral, go for the T4s.
Comparison of TinT4 vs Moondrop Starfield
Full review of the Moondrop Starfield here.
The Moondrop Starfield also uses a Carbon Nanotube Dynamic driver and they both lie within the same price range, hence, a comparison is definitely warranted. Despite the similar driver configuration, the two earphones were tuned with a completely different tuning in mind. The Moondrop Starfield is definitely much smoother and musical in its presentation whereas the Tin T4 aims for a colder and more analytical sound.
If you find yourself deciding between the two, it would become a matter of preference. I find myself leaning towards the Starfield due to it being more "fun" sounding as compared to the T4s. The T4s do have their strengths over the Starfields which are their ability to handle more complicated tracks without muddiness in the bass. This sometimes happens on the Starfields due to the slow decay of the bass on the Starfields.
Vocals (especially female) sound a little too forward and aggressive at times for me on the T4s and I prefer the presentation of vocals on the Starfield. People who enjoy a greater emphasis in the treble instead of a softer and more relaxed one would prefer the T4 for that matter.
Conclusion
The T4s do perform well with their more mature and refined tuning as compared to the T2s. One of the main weaknesses of the T2s was its bass extension and this was greatly improved in the T4s which was a really nice touch. This would make the T4s a much more easy listen formost people as compare to the T2s. However, it is becoming hard to rec the T4s today with the release of so many great earphones and IEMs in the $100 - $200 range. This is especially so when the T4 struggles with fit and doesn't really stand out in any area in terms of sound. This is not to say the T4s are bad but it just loses the value card that worked so well for the Tin T2s.

Comparison of TinT4 vs Moondrop Starfield
Full review of the Moondrop Starfield here.
The Moondrop Starfield also uses a Carbon Nanotube Dynamic driver and they both lie within the same price range, hence, a comparison is definitely warranted. Despite the similar driver configuration, the two earphones were tuned with a completely different tuning in mind. The Moondrop Starfield is definitely much smoother and musical in its presentation whereas the Tin T4 aims for a colder and more analytical sound.
If you find yourself deciding between the two, it would become a matter of preference. I find myself leaning towards the Starfield due to it being more "fun" sounding as compared to the T4s. The T4s do have their strengths over the Starfields which are their ability to handle more complicated tracks without muddiness in the bass. This sometimes happens on the Starfields due to the slow decay of the bass on the Starfields.
Vocals (especially female) sound a little too forward and aggressive at times for me on the T4s and I prefer the presentation of vocals on the Starfield. People who enjoy a greater emphasis in the treble instead of a softer and more relaxed one would prefer the T4 for that matter.
Conclusion
The T4s do perform well with their more mature and refined tuning as compared to the T2s. One of the main weaknesses of the T2s was its bass extension and this was greatly improved in the T4s which was a really nice touch. This would make the T4s a much more easy listen formost people as compare to the T2s. However, it is becoming hard to rec the T4s today with the release of so many great earphones and IEMs in the $100 - $200 range. This is especially so when the T4 struggles with fit and doesn't really stand out in any area in terms of sound. This is not to say the T4s are bad but it just loses the value card that worked so well for the Tin T2s.

TinHiFi T4 ($109): Iterating towards grace.
4.25 stars
I thank Lillian from Linsoul for the review sample. It is the understanding of this reviewer that the unit maybe asked to be returned at any time. Until then the item is mine to keep. There is no monetary compensation for the review, and words are mine and mine alone. Any reference to other reviews is for your viewing and additional knowledge only. This is not an endorsement of said links, but they are pretty darn good.

Based in Guangdong, China, TinHiFi, which was formerly known as Tin Audio is an IEM maker. The T4 makes the 5th iteration of their vaunted T-series with the former models T1, T2, T2Pro, and T3. Each iteration had their near-cult-like following, and to me built upon the sound of each. I found the T2Pro better than the T2. I found the T3 better than the T2P. I find the T4 to be the best so far, with a well-rounded sound and none of the peakiness of some of the formers. I have also liked the look of all iterations, with the svelte polished look adding what I will call “grace” to the picture. I will also admit this was surprise package on my porch as I had been expecting another audio product. Needless to say, this was a nice surprise.
Upon receiving and checking to make sure all was well; the unit was placed upon my Shanling M2x (and others as necessitated) for well over 100 hours. You either believe burn in or you don’t. My ploy is to present something beyond the new candy-store look and sound to the “I’m used to this after 6 months; how does it feel now?” appeal.
The Story of TIN T4
“As a successor to the famous T and P series, the TIN HIFI T4 is a game changer that features a revolutionary new 10mm CNT dynamic driver to ensure outstanding sonic accuracy, musical tuning, and high-resolution sound across its entire 10-20kHz frequency range. Born for the audiophile and music enthusiasts on the go, its high-end level acoustic performance will drive you to experience the evolution. Step up to brilliant sound quality and professional styling with the T4.”

Unboxing:
To say this box opening was different from past T-series would be an understatement. Normally clad in an all-white sleeve over a blue “book,” the T4 comes in an all-black box like many today. Opening the top turtle shell, you are met with two “compartments.” The bottom holds the leather case complete with cable. The top shows off the cylindrical IEM’s, replete with spoke-like wheel on the back side. Under the IEM you find a box, which contains the tips, 6 silicon and one foam. There is an informational card as well. That’s it. Not too much, not too little.
Fit-n-Finish:
I have always liked the look of the T-series, with the heavy machined-industrial touch, and the T4 is no different. Adding the bespoked wire-wheel look on the end, adds a touch of turbine effect, which complements the line and look. Made from four pieces including the nozzle, the construction of aluminum pieces is good and fit together well. The “sleeve,” which contains the MMCX connection is a bit larger diameter, but I think this is by design to give a better grip. I find it all quite appealing. A small lip allows for good connection between tip and nozzle, without the need for Herculean strength to place the tip. A welcome addition. A screen covers the nozzle so no ear “stuff” will fall in.
The cable is another thing all together. Why TinHiFi did not stay with the wonderfully soft cable of both copper and silver I do not know. It was supple and worked extremely well. The current cable is of a lightly braided 2-wire design and I do fear for its safety upon snagging something. I prefer more tightly wound cables, but this one does play well, even with the stiction. This is about the stickiest cable I have seen in a long time. My fear was that it was so tacky the cable would stick to itself or clothing. Thankfully, neither has happened and it lays well. With a long jack, the cable is well protected. No dedicated ear guides, but with a bend the cable fits neatly over my ears and glasses. I did not find a problem such as others may have experienced, but I can understand why it may happen. The cable is less prone to staying in place, and hence may come out over one’s ear. So overall, I do believe that TinHiFi blew it with this cable. Go back to the other one.
Sound:
It seems that with each iteration, the sound gets better. Or maybe I enjoy the sound characteristics more. The same would hold here. I consider the T4 to be the best yet. To me each iteration tamed the harsh tonality of which I heard. And this made me glad. The T4 is no different. Bass is the strongest yet to me of any iteration, showing wonderfully, but without that earth shaking of some on Please Don’t Tell Her. Clean and fairly deep, the bass reach falls short, but the quality is quite good. Fast decay aids in a tight clean bass. To me about as good as it can get at this price, without being too boomy.
Coming off some very, VERY good TOTL IEM’s, it can be hard to shift gears; but the T4 fit the bill for an excellent lane-changer. That one of those flagships had a mid-forward signature, which could become tiresome made me analyze the T4 even more closely. With regard to those mids of T4 iteration, I found them to be placed pleasantly and without shoutiness. These Days Without You came across like the love song it is. Todd’s voice melodious and seminal. Placed right in the heart of the song, I find myself enjoying this song as much as on those other flagships. A grand song, with a moderately defining mid tone. Just about dead center in the stage, it neither grates, nor deflates to the background. Pretty darn even.
And to top it off, the treble comes across just as I like. Slight sparkle and rolled a bit. Again, neither grating or piercing. Just fits in well to the overall schema. Midnight In Harlem is a favorite of mine for judging the top end as well as female vocalizations. Susan Tedeschi’s voice is simply sumptuous and melodic. The kind you would enjoy with a fine single malt watching the sun set from your front porch over the mountains of the west as summer comes on. And the T4 would be a good fit for that occasion. Softer edges to the treble than previous iterations (but still a bit sharper than I prefer), TinHiFi seems to be edging closer to my preferred signature. Not a bad thing.
Getting back to the music, cymbal clash behind the vocals seem to be a bit artificial, as many ChiFi (old term I know) do at this level. Still, they improve with every generation. But when focusing on the vocal aspect, they sound quite lifelike and true. Close to reality, making one feel quite welcome to song and IEM. I appreciate it when companies try to improve upon each iteration and not just to throw new models out; but genuine improvements. There are those of course who still prefer the T2 or T2 Pro (and I do the T2P), but to me the T4 is better in every fashion. To verify, I switch to my current favorite test artist, Joey Alexander. That a 16-year-old can be so accomplished makes me feel both joy and grief. Joy that I get to listen to his musical talents. Grief that I have not done enough with my life! Warna is a song, which I do enjoy hearing repeatedly for its melodic adeptness. Efficient of key, but spontaneous in generation. Joyful in representation it is, and the T4 provides enough to enjoy the song without thinking too hard on the down sides (a few as mentioned) of it.
When complications arise, the T4 can feel compressed and compromised. I liken this to me just being darn picky and a want of the flagships, which left. With good fit and tip, the T4 can provide good musical talent of its own and the merits outweigh the downsides. Just listen. Also, with a decently wide sound stage, the T4 gives an openness, which belies to technology inside. Airiness is there in decent shape and talent, and quite adequate for this range. Layering does suffer a bit with that complicatedness, but I do not mind for the song is rich and slightly warm. As the most expensive T-iteration one should expect good solid characteristics. And the T4 does provide. Mosaic (Of Beauty) follows from the same Warna album, and I forget the dribble written above and simply enjoy.
Comparisons:
TinHiFi T4 ($109) vs TinHiFi T2Pro ($50):
Each comparison should get a little bit harder as the models ramp up the sound. So here, I will bow to the conclusion of my T2 Pro review: …So, what’s left? Well, the word salad as such espousing the virtues again ad nauseum, and summarizing what the critter does well, and what it might not. Oh, the heck with that, just go buy the Pro, you will not be disappointed.
But the T4 bests the T2P in all regards. End of discussion.
TinHiFi T4 ($109) vs TinHiFi T3 ($60):
So, to continue, from my T3 review: …So, this is the third iteration of the venerable T-series. And I can say that with each they tend to get better. The T2 was marveled as an affordable well-built Chi-fi with good sound. The T2 Pro added a bit of clarity and a bit more bass. This iteration, the T3 expands upon that further. Better control than the other two, with quicker bass decay, which to me aids in a solid succinct sound, which goes a bit away from the Chi-Fi norm…that too much sparkly top end. And I for one am glad.
You see where I am going…the T4 is better yet.
TinHiFi T4 ($109) vs Shuoer Tape ($129):
I will start this by openly stating I absolutely HATE the case, which came with the Tape. It is the dumbest case in which I have ever had the displeasure of opening. It is slick, slippery, slidey, and WILL NOT OPEN without me taking two extra glasses of single malt. As Adam from Myth Busters might state, “please, please, PLEEAASSE, change it!” Once open, though you find a small tasteful IEM, which comes with a 2.5bal cable attached and includes a 2.5bal to 3.5se adapter. A nice touch. More in an upcoming review.
As for the sound, the Tape is more vibrant of signature, harkening back to the older T-series with regard to brightness. It also has a kind of funky flat mid sound. Not pinched, but different. That could most definitely be the electrostat, and the price of said electro, but it does put the signature off a bit. Gauging between the two purely on that, the T4 wins. But for some reason, I am enamored with the Tape the more I listen. Notice I did not say like, but enamored. It piques my interest and will do so more in depth. But head to head at this point in time, I prefer the T4 for its more even presentation and control of bass.

Ah, it works with everything I tried. And did so without fuss. The Shanling M2Xfit the character very well. Warmer than neutral, the M2x added a bit of hominess to the sound. On in which I enjoyed and would gladly use on commute or gym or trail. The Dethonray DTR1 is one of my current fancies, especially hooked to the HA2 amp. What a wonderful sound. Alone, the DTR1 is amongst the cleanest sounds I have. Period. Hooked to the HA2, the added juice and warmth makes for a melodious pair worthy of pretty much anything this side of a Grover Cleveland. That said, you must be VERY careful when running the lineout aspect of the DTR1. It is loud of connection and does not take much on the HA2 as a result to raise the volume to extreme levels. I warned you.
Finite:
There you have it. Another iteration of the venerable TinHiFi staple, the T-series. I continue to like the whole series but find the newer one more to my liking. It would be as if you liked your younger children more than the older ones. NO, not really! Seriously, you fell for that? In all honesty, the T-series moves upscale a bit with each iteration, and so does the price. This is the price of progress, I guess. And one where at least in this series, TinHiFi is playing it cautiously. Some will immediately jump to the $500 range with the “upgrade,” when it really isn’t. Here though, TinHiFi takes a more cautious approach, modifying and tweaking a near-cult classic. That is all right in my book, and so is the T4. It is indeed the best T-series yet.
I again thank Lillian from Linsoul Audio for the sample. Without support such as this, there would be far fewer reviews of good (or mediocre, it happens) products with which to choose. In that regard, this is a definite positive. Cheers.

Tin Hifi (formerly Tin Audio) are probably best known for their T2 model released a couple of years ago. With a neutral and well-balanced sound, rather than the more prevalent V-signature, it became very successful. This was followed by the T2 Pro and then the hybrid T3. The T4 is the latest model in the series and employs a single dynamic driver featuring a 10mm carbon nanotube (CNT) diaphragm.
The T4 is packaged very luxuriously, being presented in a discreet black box bearing the Tin Hifi Logo with the product name T4 below. Opening the box reveals the IEMs in a foam cut-out above a very nice tan case which contains the spare eartips, which include three sets of dark grey wide-bore silicone tips, three sets of white narrow-bore silicon tips, (one of which is pre-fitted to the earpieces) and two sets of white foam tips. Removing the foam layer you will find the supplied cable, which is a two-core high purity silver-plated copper type with an MMCX interface. The straight 3.5mm plug is silver coloured with knurled detail. There is a small clear spherical bobble which acts as a chin slider. The Y-split is cylindrical and of shiny metal matching the earpieces, and the reinforced earhooks are soft and supple, giving a very comfortable over-the-ear fit.
The IEMs themselves are beautifully constructed from machined stainless steel and are similar in shape to those of the T3 and T2, but the finish is shiny metal throughout. They are very light in weight. There is a small pinhole vent beside the MMCX socket and another further up the barrel at the base of the nozzle. The rear of the earpiece features a radiating metal grille resembling a jet engine turbine. The channels are identified by coloured rings on the MMCX sockets, red for right, blue for left. The MMCX connectors fitted very securely, and I did find it very difficult to remove them when changing to a different cable, so I would recommend retaining your selected cable once fitted.
The earphones were left burning in for 100 hours before testing and included tracks of white and pink noise, glide tones and other audio conditioning tracks. The principal equipment used was an Xduoo X20 DAP set to high gain. I did not obtain a secure fit with the pre-fitted tips, so I fitted my go-to JVC Spiral Dots (size ML). Their rounded shape and domed profile ensured a good seal. I also replaced the cable so I could use the balanced output on the Xduoo X20 and employed an 8-core copper balanced cable for this purpose.
It was clear from the beginning that the T4 displayed the traditional Tin Hifi sound, that is a neutral profile with good extension in the treble and a slightly brighter tonality with good detail. Where the T4 differed from the T3 was in the bass which had more sub-bass weight and power. The midrange was particularly articulate and expressive, and the treble clear and very transparent. It was hard to believe this wide frequency range emanated from just one driver.
Bass
Like the T3, the bass was largely linear in nature but with improved depth and power, especially in the sub-bass, where some decent rumble was on offer. This helped electronic music to show its full range, a good example being Jonn Serrie’s “Land of Lyss” from his “Midsummer Century” album. This track delves deep into the sub-bass and along with the very good extension the texture and resolution was top-notch and this deep bass background formed a perfect foundation for the flowing electronic effects floating over the top. “Escales” by Jacques Ibert is a colourful suite of lively orchestral pieces depicting exotic locations. The third movement, “Anime” features the whole gamut of the orchestra in a dynamic and powerful performance. In a recording by the Minnesota Orchestra under Eiji Oue, the bass drum displayed excellent depth and impact as well as an impressively natural decay. The ambience of the recording venue was beautifully rendered. “Something Inside So Strong” by Labi Siffre features a powerful bass accompaniment with drum and bass synth playing together. The T4 managed to distinguish between these very clearly while at the same time possessing excellent musicality and impact.
Mids
The T4’s midrange was a tad forward but exceptionally transparent and free of bass bleed, allowing a wealth of detail to be revealed. Vocals, both male and female, retained their individual character very well. Cat Stevens’s “Father and Son” was authentically reproduced with the individuality of his voice well-defined, and the guitar accompaniment clean and bright and the various members of the band accurately positioned within the image. “Lo Siento mi Vida” by Linda Ronstadt equally showcased the T4’s abilities with the acoustic guitars and backing harmonies beautifully depicted and the emotion of Ms Ronstadt’s vocals abundantly evident. The T4 also excelled with classical music, with the accurate string timbre in The Guildhall String Ensemble’s version of the Nocturne from Borodin’s String Quartet No. 2 very impressively presented. The separation of the various string sections and their positioning in the stereo image was also immediately apparent, producing a musically satisfying result.
Treble
I was surprised by the T4’s treble reproduction, not expecting a single DD to rival, or even exceed the resolution and extension of multi-BA models or more exotic driver types now becoming more common. With a brightness just north of neutral, transparency, detail and delicacy were all on offer and no disturbing peaks marred the sound. Mark Dwane’s MIDI guitar productions always impress with their high-quality sound and “Paragons” from his “Archives” album was no exception. Jangly rhythm guitars panned left and right overlaid by synth string patches, with a bright synth melody line over the top. Percussion and other layers came into the mix with the treble detail remaining clear and articulate, even during the complex passages. Bach’s Brandenburg Concerto No.4 in a classic 1960s recording by the Saar Chamber Orchestra under Karl Ristenpart’s baton also impressed with the woodwind and violin solo parts soaring over the string accompaniment and harpsichord continuo. The counterpoint was easy to follow and capped a wonderfully musical performance, full of vitality and joy. Juice Newton’s “Queen of Hearts” displayed expressive vocals set against a bright backing of rhythm guitars and percussion. The diction remained precise and clean throughout and the lively rhythmic qualities of the track were reproduced entertainingly.
Soundstage
The T4 possessed an expansive airy soundstage which improved upon that on the T3 with an unusually natural depiction of space. Width, height and depth were all above average in dimension, and layering, separation and positioning were all top class. Added to this, the excellent detail retrieval and resolution added to the effect. “Elsewhere” by Vangelis from his album “Direct” showed what the T4 could do in this respect with complex percussive elements interweaving across the image accompanied by sparkly electronic effects. The melody line occupied a high central position and the whole was contained in an attractive reverberant acoustic. The dynamic range in the climaxes was also impressive with decay and reverb particularly well-rendered. Pink Floyd’s “Cluster One” is an instrumental track from their “The Division Bell”album. Once again, the stereo imaging impressed with the electronic effects at the beginning occupying all parts of the stage and Dave Gilmour’s guitar solo nicely complementing Rick Wright’s keyboard work. When Nick Mason’s bass drum kicked in later in the track it had real weight and character and, being set back somewhat in the production, produced a good sense of depth. “Benedictus” from “The Armed Man” by Karl Jenkins is an expansive choral piece. The vocal line alternates between male and female choirs and then unites them in an impressively powerful climax. The words could be heard clearly at all times with the character of the voices nicely differentiated. During the climax, “Hosanna in Excelsis”, even with the bass drum and the choir in full cry, clarity and focus were maintained.
Conclusion
The CNT driver has been seen in a number of recent IEMs and possesses a wide frequency range and excellent dynamic ability. It is tuned more neutrally than the popular BLON BL-03 which uses a similar driver and has a warmer tonality with powerful bass and mid-bass. It has a more recessed midrange but lacks the detail and precision of the T4. It does have an attractive “analogue” tonality which is a contrast to the more accurate presentation of the T4.
The T4 continues the evolution of the “T” line. Adding a more solid bass foundation, a transparent and expressive midrange displaying good presence and a clear, extended treble, it maintains the largely neutral presentation of the earlier models in the series. The bass is well extended but linear in nature, so bassheads may want to look elsewhere. The midrange and treble are even more refined than before and detail retrieval is up a notch. Nicely presented with a good set of accessories and with the excellent build quality we have become used to from Tin Hifi, the T4, with its even-handed approach suiting multiple genres. is close to being the complete package.
The T4 is packaged very luxuriously, being presented in a discreet black box bearing the Tin Hifi Logo with the product name T4 below. Opening the box reveals the IEMs in a foam cut-out above a very nice tan case which contains the spare eartips, which include three sets of dark grey wide-bore silicone tips, three sets of white narrow-bore silicon tips, (one of which is pre-fitted to the earpieces) and two sets of white foam tips. Removing the foam layer you will find the supplied cable, which is a two-core high purity silver-plated copper type with an MMCX interface.

Sound Review by Kev
Disclaimer : ShenzhenAudio has graciously provided us with this sample unit in exchange for an honest review. The views discussed below are a reflection of Project A3's thoughts surrounding the product. The sample has been run-in for at least 50 hours prior to reviewing in order to achieve an accurate representation of the product.
Introduction:
TinHifi is no stranger to the budget audiophile market. Their universally acclaimed T2 and T2 Pro’s are heralded as IEM’s that epitomize the current philosophy in budget audio; that price alone does not dictate impeccable sound quality. In fact, the Tin Audio T2 and T2 Pro’s are still frequently sold on Drop (formerly known as Massdrop).
There is only so much that can be achieved by spending excessive amounts of income on audio-gear. And to the majority of the audiophile demographic, $100 is plentiful to attain gear that doesn’t drain their bank accounts. The ambitious release of the power-hungry, P1 IEMs’ captured the brand’s maverick attitude, unafraid to push the boundaries of what can be achieved at a humble price. That, and funky driver configurations.
To further the brand’s established presence in the chi-fi marketplace, TinHifi has released the T4; the spiritual successor to the cult T2 and T2 Pro. During its initial Indiegogo campaign, through word of mouth alone and Tin Audio’s glowing reputation, the campaign secured funding upwards of $500,000 SGD.
The T4 features a carbon-nanotube (CNT) diaphragm; a popular diaphragm material that is used by costlier IEMs’, except they’ve stuck to their roots, selling the T4 at a reasonable $99 USD. What makes the material, CNT special (from a layman’s perspective), is its ability to displace air rapidly, reducing unwanted vibrations and total harmonic distortion in the process.
But, as seen from the hype surrounding its successful Indiegogo campaign, would the Tin Audio T4 be able to meet the monumental expectations of avid audiophiles?

Unboxing:
On first glance, the non-descript cardboard box features nothing but an embossed logo with gold leafing, spelling out the name of the brand, and the model below it. Removing the lid, reveals the impeccably finished T4 Shells, alongside a tan leather case with a magnetic flap/lip and regular silicon eartips (S, M, L), 1 pair of foam tips and spin-fit styled tips (S, M, L).
Opening the leather case unveils the high-quality, mmcx silver-plated copper cables alongside a velcro cable-tie.
For $99 USD, I wouldn’t expect a premium case, let alone a braided silver-plated copper cable. Tin Audio has spoiled the market with its package that far surpasses its already affordable price tag. It is easy to see why the brand has a loyal following. The hype is certainly warranted.
Scalability:
The TinHifi T4, with its low impedance and high sensitivity, is easily driven out of all the sources I used for testing. There was no discernible hiss or static from any of my testing gear, including the Aune X1s with its high-impedance output.
However, because of its low mechanical impedance, it is harder to achieve a significant damping factor to exert more control on the driver. Nevertheless, when the T4 is fed more power, there is a slight improvement in the lower-end, with a snappier mid-bass response.
Overall, the T4 sounds crystal clear out of all sources and works well with many paired sources.
Fit:
Despite its rounded ear-shape akin to that of the Sony IER Z1R, the T4 sit well on my outer ear canal. Its lightweight aluminium shells are featherweight, sinking into my ears, barely noticed during my long listening sessions prior to composing this review. The cables are supple and pliable, easily conforming to the outer earlobe without placing any excessive strain, distributing the weight of the cable evenly. TinHifi’s signature L-R markings (as featured on the T2 and the T2 Pros) are back, using red and blue coloured rings around the mmcx connector for easy identification.
Its nozzle is fairly long, allowing for decently deep insertion to attain a tight seal. Because it seals so well (especially when paired with the stocked spinfit tips), the T4 offers above-average isolation. On the daily train commute to the city, the T4 managed to drown out the monotonous hum of the train engine by 70% at regular listening levels; a remarkable feat, considering it has a small pinhole vent next to the nozzle. These are the ideal grab-and-go everyday carry earphones.
However, it is tough competing with the ubiquitous adoption of universal acrylic shells, one which utilizes a form factor that is widely accepted as the most comfortable shell design available in the massive IEM market.
Sound Sig:
The T4 is incredibly balanced. It is resolving, articulate with a slight mid-bass bump to liven up its representation of music. What makes the T4 unique is its ability to adapt quickly to most of the genres thrown at it. Its pristine representation of the entire frequency spectrum makes it an audio-chameleon. Despite its linear sound-signature, there is a fun-mid bass lift to ensure music sounds dynamic and musical enough for daily listening.
Bass:
The T4 is a bass-light earphone. Apart from a slight lift in the mid-bass department, the lower registers sound full enough without overstaying its welcome, decaying quickly so as to not stray too far from its neutral sound signature. It stays in its own place, without ever bleeding into the upper registers.
However, on songs such as Natalia LaFourcade’s Soledad Y El Mar, there’s a noticeable lack of weighty low-end and sub-bass bloom, resulting in the string sections lacking both reverb and warmth that are characteristic of acoustic guitars. Without that slightly slubbier low end, the classical guitars and double basses sound slightly hollowed out.
In the defence of the T4 however, a speedier bass response ensures minimal bleed in the mid-range, prioritizing clarity and realism.
However, the T4’s excels with all genres of music, sounding inoffensive in the bass registers without boosting any bass qualities.
Mids:
The T4’s mids are dynamic and clear, sounding incredibly clean. Across the entire track list, it was hard to pinpoint any glaring faults. It adapts quickly to what is being played on it. However, it does favour upper-mid clarity and sparkle over the lower-mids which tend to blanket the entire mix with too much warmth. As much as I prefer a heavy emphasis on timbre and even-harmonics, the T4’s tuning Is much more mature, defining itself as a jack of all trades, avoiding unnecessary colouring of the entire frequency band.
With tracks such as Chasing Kites by Iamamiwhoami, which generally favor the traditional consumer V-shaped sound signature, The T4 represents the tracks pulsating kick-drums and crisp synths fairly well. Even the voluminous thud of the kickdrum is fleshed out pretty accurately on the T4, with Jonna Lee’s porous vocal melodies sounding clean and full.
All in all, the mids remain unadulterated; what you hear is what you get.
Highs:
Like the T4’s midrange, the highs are given enough room to breathe, without any purposeful attempt to tame or tweak the highs; it is neither extended or muted. In Ryo Fukui’s Scenery, the striking of each key sounds refined and effortless on T4. From each key to the next, the track radiates an impressive high range that somehow manages to sound smooth, without any trace of harshness. The T4 is a polished piece of kit that plays well with so many tracks across a multitude of genres.
Treble:
Now, “treble” is the widely divisive quality that has split the audio community; you either love it or hate it. If you’re either a treble-head or a treble-sensitive listener, the T4 straddles the line between both realms, attempting to appeal to opposing ends of the spectrum.
Thankfully, it does this with ease and more successfully than its pricier counterparts. The treble is slightly splashy, with enough shimmer and forwardness to prevent it from sounding overtly thin. On songs like My Queen is Harriet Tubman by Sons of Kemet, the hotness of the ride and crash cymbals do not sound sibilant at all, bereft of any of the associated harsh overtones that are characteristic of brass cymbals. Most importantly, the highs still are pushed far enough so as to remain captivating.
Soundstage:
At $99 USD , the T4 displays above-average staging capabilities. Horizontal width isn’t an out-of-the-head experience, but it sounds wider than most earphones in a similar price category. With the track, Dispossession by Algiers, vocal cues from the background singers can be clearly heard, without sounding too distant nor too close to the lead vocals on the track.
Separation:
Because of the T4’s linear presentation, each frequency band sounds distinct from one another, and it isn’t all that difficult to position or identify instruments or vocals in a 3D soundstage. It is important to take note that this isn’t a $1000 IEM or a multiple balanced-armature setup. Do not expect excellent imaging capabilities that rival flagship status IEMs’. What the T4 does well in however, is coherence, no thanks to the utilization of a single, full-range dynamic driver. Sometimes, less is more.
Musicality:
The TinHifi T4 is a powerhouse of an IEM that is well-adept with all genres of music, ranging from the free jazz to chiptune. To cut this section short, the T4 pairs well with all genres and doesn’t excel in one particular one; it just sounds great all around.
Comparison:
TinHifi is considered a resident favourite in the chi-fi audio scene. I decided to put it in its paces, challenging a North American brand, Periodic Audio, with their entry-level Mg (Magnesium); a single dynamic-driver IEM with a unique magnesium diaphragm.
In addition. The Shueor Tape serves as a more expensive contender, to see what an extra $50 offers in tangible value.
Lastly, the Tipsy Dunmer, could be seen as a direct rival in the chi-fi marketplace vs the T4, considering it houses a single dynamic driver as well.
Sound Conclusion:
The TinHifi T4 is an IEM that offers tremendous value for the “everyday listener” that favours not only flexibility, but a resolving sound that favours accuracy and clarity. At $99USD, the T4 is a steal and I can see myself grabbing it as my go-to IEM for my day-to-day listening sessions.
I would even argue that the T4 is valid competition against IEMs’ that are significantly more expensive. Sound like this is unprecedented in this price category. I look forward to seeing more releases from Tin Audio.
Aesthetic talk by Steve ( TinHifi - T4 )
TinHifi was one of the successful example of Chinese audio these years by introducing their budget lineup starting from T2 and til now from the result on the Indiegogo campaign for the T4, pretty obvious that the new gem has been successfully drawn so much attention before the official release and is highly hyped again in the budget audio world , if you track back to their previous models on the T lineup, there wasn't any noticeable changes on the Aesthetic side in between T2 and the T3 but today on the T4, I think it's a good time point to talk about their effort based on this criteria.
Colour:
Comparing to the T2 T3, the changes on the Colour has changed to a silver glossy finishing which make things look more chic and trendy this time, you will notice that many brands are now producing metal shells , glossy finishing on mass production which I believe it's starting to be the trend of the iem industry. back there on the T2, T3 the whole feeling leans towards to a more Industrial design and was a bit hardcore on the overall presentation. the T4 this time somehow reminds me of the Sony IER-Z1R but of course a " simplicity" and much smaller housing one. By looking into the recent trend, IEM with similar finishing, no matter it is electroplating, aluminum or stainless steel has proven that the Aesthetic is more acceptable on the marketing side and was a good shift on for the T4 in making such decision. Great decision made here on making the appearance more commercial and up to date to meet the modern aesthetic trend,comparing to the T2 T3, the T4 made a successful move to achieve a more premium feel. However the plastic blue/red ring that indicates left /right on the mmcx plug should be considered to swap it with a electroplating finishing one for a more consistent look with the metal shell for the next generation of the T series. Something like the Meze did on the rai solo would be a great idea either.
Craftsmanship:
Judging by the sample that I got, overall the built is pretty solid, weighting for a metal build iem is good, not much pressure on ear, satisfied for long time listening. However the flaws that I noticed is the mmcx plug seem to be a bit wobbly and also there are some tool marks ( photo above) on the shell caused by the CNC process, you can see the marks under sunlight and in certain angles , but of course for the price I think this is forgiveable as even if the turnings has been adjusted to be a more precise and slower speed which definitely will add more cost onto the project, it still have a certain chance of getting shallow marks on it. It's only about the degree of the issue So why bothered?
Design details:
Besides the change of the finishing we said before, another major change of the design is the faceplate. I've talked with boss of TinHifi directly about the design and they said the idea was inspired by turbocharger, indeed you can tell by the faceplate this time, the whole design is on point, without being too exaggerated or too similar to a actual turbocharger. Craftsmanship on the faceplate is very detailed, precisely made from the CNC process, edges are smooth without any corner spikes, it's always good to see a design starting from inspiration and this time the T4 really deserved a big thumbs up comparing to the T3 transmitting from the T2. A relatively fresh feeling here that differentiate the T4 from the other models in the T series.
Silhouette:
Nothing much to talk about in this aspect. It's basically just a over the ear bullet shape iem, no weird outlines or disproportionate on the whole. Other than the silhouette itself, the fitting might be a bit tricky for some to get it place properly into your ear canel also ergonomic and isolation would be relatively a slight down side comparing with those universal acrylic shells out there since the design of T4 is more relying on the proper eartips to get a better isolation just like the typical bullet type iems, so if you are expecting something fits really well and sticking tight fit to your ear shape, this might upset you a little. But overall this shouldn't be any issue for most of the people in general listening.
Cable:
The cable itself is a significant improvement from the T2, however the rubbery cable sleeve might bother some people especially when they dont get their cables tied properly, it will definitely drives you crazy when you are trying to untie it, after all this issue is more of a personal preference. But speaking of the cable quality itself and regarding the price tag of T4, it's quiet a decent cable especially when comparing with some of the competitors in the same price segment and I do suggest Tin audio to start designing their own plugs in order to establish a more define image on their branding and for product line ahead.
Packaging:
This is another significant upgrade from the T2, the package box itself looks much more Hi-end than the models before, the use of the silicon texture for the box seem to be a trend of packaging nowadays in China , already seen couple of brands using it such as IKKO, NFAUDIO etc. And indeed it looks pretty decent along with minimalist design idea. The presentation is average, not the best but more than satisfy and What really impressed me here is actually the earphone case. For a 99USD IEM THIS IS A STEAL. The whole case looks pretty similar to the one that was provided by Hidizs ms4. Slightly smaller by looking at it side by side , but generally it gives you the same texture, same quality built, a sturdy and premium case that you will have no complaints with.
Conclusion:
The T4 is truly one of the most impressive project out there in the 99USD bracket, from IEM design to package presentation, offering one of the best case out there, all these elements that meets all the general requirements that customers are asking for. It's really hard to fault TinHifi on the T4 particularly in this price market. By talking with the boss of TinHifi, I can sense how ambitious and passionate they are aiming for their coming lineup. Not just on sound but also on Aesthetic side, Will TinHifi maintain their hypes and break a new selling record in 2020? Let's sit back and see.

I am a student who loves to talk and write about everything I made and found. Music/Audio happens to be one of them as I listen to music daily and play some Piano/Guitar along the way. My music preference is Rock, J-pop and especially Instrumental, I do listen to other genre of music if I happen to enjoy the song provided.
The review is from my website: https://banbeu.com/tin-hifi-t4-review/ with some editing to fit the time I am writing.
Introduction:
Tin Hifi, despite my dissatisfaction with the P1, they still seem generating new hypes every time they release a new product. The Tin Hifi T4 is no exception, with tons of positive reviews from reviewers who received the product early just to "tease" their audiences and more or so with a successful crowdfunding campaign of over 300.000$ on Indiegogo, no doubt it is one of the hype of the chifi community in the last quarter of 2019. So, while most of the reviews out there are far before the release of the earphone itself, this post will be one of the first reviews of the Tin Hifi T4 after its release to the public, reflecting my own experience with it after a few days using it.
Informations:
- Price: 110$
- Drivers: 1 DD
You can purchase the Tin Hifi T4 on linsoul website after a few days.
Packaging and Builds
- 3 pairs of white silicon tips (S/M/L)
- 3 pairs of black silicon tips (S/M/L)
- Pair of foam tips
- 1 leather case
- 3.5mm unbalanced MMCX cable (Which Tin Hifi also claim to have a market value of 35$)
- The IEM itself
The Tin Hifi T4's build is metal as usual, but the coating is different from T3 and T2, there is also a new jet-engine like pattern on the back plate also. For some reason, the earphone has actually shocked me several times when I tried to use it with my laptop, something which hasn't happened to me when I tried their past product. While this issue is common for metal IEMs, I will give out this warning for the first time to future Tin Hifi buyers. (Or at least, ground your house...)
Sound:
Signature & Measurement:
Measurements are done on a steel coupler with dynamic microphone, while the result seem to be close to an IEC 711 coupler, there are noticeable roll off in the bass region and frequencies higher than 10kHz is also expected to have roll off.
The T4 seem to follow a neutral bright signature from its predecessor, but I have seen different interpretations of it: mildly V-shaped, U-Shaped, some even would even say it is warm-neutral. But, I think it still can be called as a neutral IEM despite the tuning.
The bass seems to be more focused in the sub-bass region rather than the usual mid-bass which gives more rumble to the T4, but not really punchy in anyway whatsoever so I would still obviously not recommending it to bassheads. The lower mids are slightly elevated and the upper mids peak nicely at 2kHz, there is also a peak on 6kHz, which can make vocals shouty depending on song choice. Finally, treble roll off after 6kHz, so cymbals don't seem to shine much on the T4.
Subjective opinions:
Surprisingly, while I expect a somewhat thin sounding notes from the T4 after hearing its predecessor, the reality seem different. Vocal for some reason sounds thick and while I am not that impressed with the T4 on many "weeb" song in my music library like 凋叶棕 - ためすがめ due to the high-pitched "anime" females vocal doesn't sound right to my taste, I was able to enjoy songs with male vocals like Baio - PHILOSOPHY! more than I usually do.
Comparing to T2 and T3, the Tin Hifi T4 tuning is less bright and less aggressive, providing a more balanced sounds across the board. It also sounds different from the newly released BLON BL-03: The Tin T4 is more shouty on female vocals and its bass lacks punch comparing to the BLON.
But, putting away my complaints about the tuning of the T4 which goes by my preference more than anything, the T4 note clarity is good, better than most (if not all) of the past Tin Hifi product (Yes, I think it beats the P1 technical wise, I wasn't a fan of it anyway despite the fact that it was an improvement to Tin Hifi past product at the time). Although this earphone imaging and soundstage is seemingly "average", for 110$, its technical ability seem to shoot nearly everything in this price range off the cliff which is really impressive.
Conclusion:
I usually would try to write some more of my thoughts about the IEM that I am reviewing, but this time, let just keep it short: Do I recommend the Tin Hifi T4? Yes! For 100$, in my opinion, it is the best that Tin Hifi has to offer and I see the earphone would still be relevant in the future as a solid recommendation to a lot of people just like how the T2 was. Hats off to you Tin Hifi.

100+ Head-Fier
Pros: Design, build and comfort well above price point. Neutral Ballanced tonality with excellent timbre, all frequencies perfectly represented, soundstage almost holographic
Cons: Imaging and detail not as on point as I've heard at this price. Upper mids can be a touch in your face with silicone tips, the supplied T2 foamies smooth this out though
This is my first review outside of listing reviews so apologies in advance
A short intro about myself: I can't profess to have anywhere near the experience of others here but I've been keen enthusiast of music, production but particularly its reproduction for many years. From DJing in some fairly well regarded cubs during the heady 90's rave scene, some rudimentary producing but mostly decades of keen listening using only the best music I can afford. Up to recently this included a set of custom Wilmslow Audio Studio Monitors driven biwired by 2 Audiolabs, a Linn CD player and my trusty old 1200's as source, so I have a reasonable reference point of quality gear.
Unfortunately life events changed so I had to trade most of this in, lost for affordable quality audio I happened on what was coming from China at relatively rediculously cheap prices. I chanced a set of kz as10's and while far from perfect was blown away by what chifi's producing, genuine 'audiophile' sound at budget prices. I've since been bordering on the obsessive and at some point owned all 'the better' regarded KZ's (as16, ZS10 pro, zsx an extremely accomplished iem), CCA's (cca10, c12 and C16, superb, reference class) Trn's (the new Ba5's rediculously well tuned for a sub $50 all BA IEM) Shuoer Tape, a couple of Senfers and everything that Tin hifi have produced (T's and P) up to and now including the T4. I've forked out my own hard earned cash for all of the above including the £62 for the T4 from the Indiegogo 'Campaine' (still not sure why Tin Hifi would need this being their apparent establishment, but hey so long as its a few quid cheaper, makes it a bit more special, purchased on day of release I received them yesterday just over 2 weeks later.
Opening the box your immediately greated with a far more premium experience than the T2, T2P even the T3 (and Tin do do premium presentation well) using a similar black box to the P1 with a comparable array of accessories including a new, much larger ,leather carry case and their usual well above average array of quality silicone tips and just 2 of the grey Tin Foamies (3 pairs of T2 blues also in the deal). For testing I used the T2 tips and set of cp145 spinfits (although tbh I found the included silicone tips virtually as good)
Build quality is even even better than Tin Hifi's usual top notch standards (P1 excluded), the IEM's are cnc machined steel alloy, unlike earlier T series incarnations the T4 is not bullet like in terms of weight as well as build, the T4 is machined from mysterious substance lighter than air. In fact I could bearly feel any weight at all holding both iems and the cable, doing the tried and tested piece of chocolate method the entirety weighed less than 1 and half cubes of Cadbury Dairy Milk I had at hand. The cable is a simple twin braid which looks exquisite with the machined back to the housing. My only complaint would be the cable is slightly tacky to touch and therefore tangle prone. I never thought weight was an issue until wearing these you wouldn't know they're there, ZERO fatigue (in every respect). Using the classic old bullet design the diameter is slightly narrower with an almost sexual fit (my apologies just the only way I can describe a tin hifi T fit). This provides superb isolation and I suspect better acaustics, presenting the sound to your ear drum directly and securely, certainly to my ears and I'm yet to hear much different! They are by far the most comfortable headgear I've ever worn, superb ergonomics and virtual weightlessness means that even after 5 hours straight I don't even know there there, I never realised the weight of an iem mattered quite this much.
For testing I used my Fio m6 as source playing mostly Tidal Master quality via my Tempotec IDSD plus (better known as the Hiditz dh1000 - rediculous value at about a hundred quid from Ali for a superbly tuned neutral Dual Sabre Dac, looks boss too). For testing I've played some of my favourite test tracks from Radiohead (in Rainbows mostly), Some Zeplin, Beafheart for some more avant garde Jazz thing, a few Damien Rice live and other acaustic tacks and a couple of live albums from Daft punk and justice to cover edm.
Unlike nearly any Chifi iems these required zero burn in or 'adjustment' (depending on which side of the argument you fall) there was no unusual peaks, bloating or general weirdness they sang to me straight from the box, more so their incredibly easily driven from a reasonable smartphone, as well as a low powered DAP to more dedicated focused and powerful Dac/amp, they require no pushing and didn't sound strained at any point.
Lows are strong but almost delicate in texture, sublime! Deap sub bass rumbles can be met whilst mid bass are tight enough, I wouldn't describe bass as tight and authoritive but realistic (had my fill of overly tight almost bomby bass), I'd say relaxed but on point
To my ears these are the most balanced iems Tin Hifi have done and the mids represent this perfectly their just there, where they should be, detailed and textured beautifully with a timbre I've personally not hears on an iem near this price (even on high end cans). Male vocals are right there articulate detailed and strong ,female vocals just have a clarity and tenderness every note distinct sweet! Upper mid vocals can be a bit intense with silicones (cp145's) but smooths out nicely with foams
Treble perfectly pitched with a reasonable amount of detail retrieval, others have found them overly bright and I'd agree with silicone tips this may be the case but use the supplied T2 (or foamies of your choice) and this is nicely tamed. I've heard better detail and imaging at even half this price but the presentation is everything I'd want to hear on the recording (do I really need to hear the bassist fart! ). There are many more iems even cheaper than this producing more detail throughout the frequencies but there's a richness, engagement and musicality you hear here you'd only hear on high end gear way beyond this price point and I believe this is where the T4 lives with that premium vibration!!
Staging is magnificent broud, deap, high low, whatever, holographic to my ears. Combine that with the fact i can hardly feel I'm wearing them and i really am there, each instrument playing with tenderness, authority, richness and reality. Positioning is pretty good but like the detail, being a DD you won't get that pin point accuracy and sharpness you may get from BA's etc so could appear slightly vague almost, compared to many IEM's near or even bellow this price point.
In summation theirs a premium quality oozing through the T4's from there design, accessories to their build but mostly in the musical presentation, there's richness and delicacy combined with enough authority to really present a well poised beautiful sound, especially at this price, the only weakness might be I didn't find they amp as well as some.
If I was to sumerise in one word.....deft (deft and sublime if I could have 2)
I understand on general release these will retail at around 110usd, I still feel this is good value as they easily compete if not beat a Shuoer Tape (one of the most regarded midfi iem) and imo Tin Hifis very own P1 retailing at approximately 30% more. There are things either of the 2 mentioned iems do do better but as an overall package (especially accounting for comfort and achieving a good seal) but require a lot of work faffing with tips or acquiring the power from a medium sized power station, the T4 just does this effortlessly
Perhaps the best summation would be technically the likes of the Tin hifi p1, Shouer Tape, BLON BL-03, TRN BA5 may well ofeen beat the T4"s in 90+% of areas but they lack that rich premium timbre you only get with truly high end gear

Thank you Nimwerth does appear we certainly frequent the same bars lol. Tbh maybe poor fit or something but never got on with the Blons similarly the Tape, I'd happily pay tripple for comfort, an underrated thing (#### I'm getting old lol)
daverdoodles
You mentioned having the KZ ZSX, I too have that model and found it to be amazing for the price. How do the T4's stack up directly against the ZSX?
I have some T4's on the way but I was just curious what your thoughts were.

Haven't got the zsx anymore to properly AB but from memory the T4 does have a more neutral tune and better more natural timber, the zsx is more V/U shaped has better micro detail from its BA's and more impactfull bass. Compliment each other well

Intro
The TIN HIFIT4 is the in-ear which the T2 Pro could have been and the T3 should have been. So it took a while until a worthy successor of the popular T2 came out. The T4 is a perfect symbiosis of the T2 and the T3 and combines both advantages perfectly, without reproducing its disadvantages. The whole thing is done with a dynamic driver, which is almost perfectly tuned to the given possibilities of a single driver.
Handling
To see that the T4 belongs to the TIN HIFI T-product line, just take a quick look. The evaluated case design of the T2, T2 Pro and T3 is also used in the T4. As an optical eye-catcher, the T4 has fine lamellas that resemble a turbine, which sets it apart from its relatives. Also the metal is not matt, but polished, the rest remains the same.
For the cable, TIN HIFI does not rely on reinforced material, but likes to constantly go other ways with its models. The cable of the T3 was really an eye-catcher, both haptically, optically, but also on the workmanship.
With the T4 we get a cable, which NICEHCK often likes to add to its MMCK-IN-Ears.
It has "only" 2 cores, which have a good diameter and are silver plated. It has a rubberized coating, which doesn't feel as smooth and supple as the previous models. However, it is very comfortable to wear and does not really tend to knot.
Talking of comfort, the T4 is not to be outdone if you also rely on the right tips.
In this context, you can also influence the insulation, which is very good with the foam tips supplied.
The transport case is also a small highlight. It rather reminds of a jewel case, which is covered with leather and has a soft inlay. TIN HIFI knows how to put a smile on the face of their customers with the accessories, as with the T4.
Sound
Let's get to the actual topic: The T4 has really gripped me in terms of sound and so far represents the most mature in-ear of TIN HIFI for me, I'm deliberately ignoring the P1 here, because it stands alone and with the right DAC behind it is really a small work of sound art for me.
Back to the T4, which has hardly any weaknesses and if so, these are not of technical origin but simply a matter of taste. I always have a hard time with statements like: "This is the best in-ear under 100€" or something like that, because that can only be a personal feeling for myself, but the T4 does damn much right to negotiate such a status, because it doesn't only want to appeal to a small category of audiophile listeners, but the broad audiophile mass.
TIN HIFI is not known for its invasive bass in terms of quantity. However, it usually offers a controlled, detailed, dynamic bass that is more at home in the midrange. This is also the case with the T4. However, the expansion into the sub-bass range is more pronounced and, for my taste, more stable, fuller and rounder than its predecessors. It blends in perfectly with the sound without being too intrusive, but not too shy either. Very well-balanced and linear, it always finds the right balance between noble restraint and powerful substructure, depending on what is required of it. Rarely have I heard such a balanced bass that nothing really disturbs me.
Meanwhile you read more and more about the Harman curve when it comes to the tonal characteristics of an in-ear. This curve represents a curve which should come close to the current "ideal" sound image for the majority of society and is adjusted annually. The T4 is strongly oriented towards this, but for me it has to admit defeat in the mids compared to the Kanas Pro (also Harman). These are more advanced in the upper regions and not quite as relaxed and soft as in the Kanas Pro. On the other hand, they suggest more clarity and assertiveness with the T4. The voice reproduction is very successful with the T4, because although the upper mids are somewhat more prominent, which usually gives female voices more vitality, male voices are just as good. Be it by the solid body through the precise bass, which does not slip into the mids, or by the present lower mids. TIN HIFI has always had the knack of presenting mids in a very natural and tonal flawless way. They do the same with the T4 with ease.
The treble is also an outstanding feature of the T4. Somewhat bright, but not too exaggerated, they have an amazing extension. They open the sound far upwards, so that music never sounds pressed at any time, but can always move freely in space, which leads to a wonderful separation and spatial representation. They don't sound too metallic or unnatural in any other way. They bring this infamous sparkle to the top end and always surprise with fine micro details. There are no signs of fatigue even after a long time of music enjoyment. But you should keep an eye on the volume. Not that the T4 gets dirty at higher levels, but still the rise in the upper mid-range (5 kHz) could become a bit independent and the signature could drift a bit too much into brightness due to higher gain in the higher frequencies.
But what really makes the T4 a must-have for me, or let's say at least a listening test, is the stage, but especially the 3D presentation. Here you can hear everything you need to hear, neatly distributed throughout the room. Maybe some more expensive multi-driver models can do that even better, but here I see the T4 at eye level with the Kanas Pro, in detail even more brilliant, but the Kanas sounds rounder and more mature.
Outro
What else would I want from the T4? Slightly smoothed upper mids and a slightly warmer disposition. The T4 is far away from sterile, but it could still bubble a bit more vitality out of the small turbine. But that's really just a subjective perception and a lot of complaining on a very high level. I'm really fond of the T4 and can recommend it without a guilty conscience, for all those who are looking for a natural, directionally neutral V-signature, with balanced bass and good sub-boost, precise, tonal correct mids and an excellent expansion in treble without fatigue factor. In addition one gets an outstanding spatial representation, which scores with vocal intimacy and astonishing separation in depth and width.
However, it won't be a perfect match for those looking for pure fun headphones. Fans of absolute neutrality might also dislike the upper mids and the sub-rise.

Maybe some more expensive multi-driver models can do that even better, but here I see the T4 at eye level with the Kanas Pro, in detail even more brilliant, but the Kanas sounds rounder and more mature.
Outro
What else would I want from the T4? Slightly smoothed upper mids and a slightly warmer disposition. The T4 is far away from sterile, but it could still bubble a bit more vitality out of the small turbine. But that's really just a subjective perception and a lot of complaining on a very high level. I'm really fond of the T4 and can recommend it without a guilty conscience, for all those who are looking for a natural, directionally neutral V-signature, with balanced bass and good sub-boost, precise, tonal correct mids and an excellent expansion in treble without fatigue factor. In addition one gets an outstanding spatial representation, which scores with vocal intimacy and astonishing separation in depth and width.
However, it won't be a perfect match for those looking for pure fun headphones. Fans of absolute neutrality might also dislike the upper mids and the sub-rise.

As I write this, I just realized I never tried the Tin T1, and I know nothing about it. But that aside, the product line from Tin Hifi has been decent to good. The Tin T2 was an instant chi-fi classic, with a neutral reference-like sound signature, good build quality, and removable mmcx cables at an affordable price. The follow-up T2 Pro had a very bright signature, that some like and others hated, and the T3 took parts of the T2 and T2 Pro and added just a Balanced Armature driver to give it just a little more resolution, and slightly added warmth and was pretty successful at that.
The last Tin Hifi product I reviewed was their attempt at a Planar Magnetic IEM, the P1. This one had mild success in my eyes. It had a better out of box tuning than any other planar magnetic IEM I’ve tried (that is, default tuning with no modifications or equalizer applied), but the bar is quite low in this aspect, and the tuning still had some flaws such as overly bright tonality, and in-your-face soundstage, or lack thereof.
Introducing…
Quickly on the heels of the P1, Tin Hifi announced their latest creation, a dynamic driver, Tin T4. This new item retails for $109, but will be sold on Indiegogo at a special early bird price of $79 starting on Nov 11th.
While in some ways, this is their simplest effort yet. Unlike the previous T-series I have tried, the T4 only has a single dynamic driver, while still retaining a generally similar housing shape and size. This new housing is much more intricately designed though, with a milled design that is reminiscent of a moving turbine blade engine.
The new housing is still made from aluminum and feels rather light and nice. The connectors feel more sturdy than previous iterations, and the new cable is silver-plated and looks luxuriously braided with thick wires. In a small change from the past, the T4 is designed to be worn over-ears, instead of drop-down cable style like on the T2.
Also included are a variety of tips and a really nice fake-leather brown jewelry-style flip box that has plenty of room to house the IEMs and a couple other small accessories.
Sonic Barrier
When I first put on the Tin T4, I was quite reminded of how the Custom Art Fibae 7 sounded for some reason. It has a neutral-ish reference type sound that I like with a touch of bass elevation that gives it just enough warmth to sound balanced, and not overly bright. The T4 has that same type of sound, while perhaps being a tad brighter, but not in sounding harsh or sibilant.
Frequency Response Graph -- Note Channel Matching was exceptional!
I was actually very pleasantly surprised by this IEM. It fits closely to my ideal neutral reference sound signature. The bass levels are right about where I like it, giving more quality than quantity. There’s still enough sub-bass quantity to provide rumbling texture in songs that provide it, and a smidgen of punch when necessary, but in general, it is a little lighter than other IEMs, especially those that are coming out of the Chinese marketplace lately.
The mid-range is quite coherent and just slightly warm. It’s not thick and lush, nor does it sound thin to me. It sounds just how I’d like it so that every frequency stands on its own and doesn’t get bloated or becoming missing. The midrange is forward, just like the T2 and T3 before it. The pinna compensation begins around 1KHz as expected, and rises up quite high to a 2KHz peak and a reduction at 4KHz and another into the lower treble with a peak at 6KHz and a smaller one at 8KHz.
The 6KHz peak doesn’t bother me, and typically doesn’t unless it’s overly boosted. The 8KHz are is where I have seen issues with past in-ears, but since it’s lower than the rest of the upper-midrange and lower treble frequencies, I don’t have any issues with sibilance or edgy harshness with the T4, and I did put this IEM through several pop tracks with female vocalists and known edgy songs for me and the T4 seemed to past with flying colors.
This type of elevation in this area does make female vocals really stand out, and I do enjoy that. I love hearing vocalist’s emotion and bravado in their voices and having this type of rise really pushes that forward.
The troughs and rises do help give the T4 with an adequate soundstage width, and I found the T4 to have just enough to separate instruments clearly and deal with congestion pretty well, which isn’t something I can say with many IEMs in this type of price range.
I do think the T4 struggles a little bit with raised volume levels. While I typically do listen at around 70 dB/SPL when I’m using IEMs and headphones, occasionally I do raise the volumes a bit. I found the T4 to sound a tad strained and perhaps distorted slightly at higher volumes (I’m thinking 80dB and more). But at my moderate listening volumes, I find the T4 to sound clean, clear and actually surprisingly good.
Some Selected Comparisons:
Moondrop KXXS
Normally, I would compare it with the Moondrop Kanas Pro, but since the IEM is now discontinued, the next best thing is their successor, the KXXS. I actually think the Kanas Pro and T4 sound very similar up to about 4KHz, but the Kanas Pro has a more laidback sound with reduced treble, while the T4 has more clarity due to the increased treble presence. Ok, so I guess, I did compare to the Kanas Pro after all.
Now, the KXXS, it has noticeable more bass elevation, impact, sub-bass quantity, and longer decay than the T4. This could be good or bad depending on your tastes. For me, I like the T4’s bass levels because, in comparison, I find the KXXS’s bass decay to extend into the lower mid-range and actually that actually ends up muddying up a bit.
I also find the KXXS to sound harsher and brighter, and surprisingly the T4 doesn’t have that issue, despite having what seems to be a measured higher response in those areas. I think where it differs is that the T4 has a big roll-off in the upper registers, and the KXXS has some rise there.
So, for me, I was surprised that I prefer the T4 more than the KXXS.
Etymotics ER2 Series
I think the Tin T4 fits somewhere in-between the ER2 Studio Reference (SR) and Xtended Response (XR) models, and this is particularly where it’s bass and mid-range falls. The T4’s response is warmer than the SR, but not as warm as the XR. I think part of this is due to the T4’s higher rise in treble, which shifts the overall balance towards that area over the lower frequencies. This makes the XR have the same type of relative comparison to the T4 as the KXXS has above.
I think both are similar in terms of overall quality though, but the ER series is extremely better at isolation. The ER2 series also has a more natural timbre due to the lower treble, but some may find that to be a slightly laidback in a sense.
Blon BL-03
Both have a shallower fit, though I find the Tin T4 to be much more comfortable to wear and easier to just put on and go. I had a lot more trouble out of the box with the BL03 with finding the right fit and seal and it was pretty instant with the T4. While the BL03 is a good, even great, value, I actually didn’t like it as much as many other people have. This is partially due to the sound signature being a little too bass and treble emphasized, and lacking mid-range forwardness.
For the most part, I found the bass too heavy, and wished it was a few dB lower. That’s why I find the T4’s bass levels to be ideal for my personal preferences.
Overall
I find the Tin Hifi T4 a competent and good IEM, and I’m actually very happy with adding it to my collection. It’s the right type of sound signature for what I enjoy and I’m happy to recommend it at the introductory price, and even a strong consideration at the regular retail price. I think those who prefer a neutral sound signature will find this one right at home, and it comes with a nice set of accessories to go with it.
The Tin T4 is an improvement and easily the most complete Tin Hifi product to date, and easily out performs the recent P1, which again, wasn’t one I particular liked.

This a review of the Tin HiFi T4, the single dynamic driver successor to Tin HiFi's T2 and T3. I got the T4 early as a review unit from Linsoul and it will go on sale on November 11, 9:00AM EST on Indiegogo for $79 as an early bird special + $20 in-store credit at linsoul.com Otherwise, it will have an MSRP of $110. Here's the Indiegogo link: https://www.indiegogo.com/projects/tin-hifi-t4-in-ear-monitor-earphones
About Me: I've been a live sound tech for the past 6-7 years at a church as a hobby and I play the piano occasionally on the side. My current daily driver is the Sony MDR-EX1000 though I do enjoy dipping my toes in the ChiFi world. Rock is my favorite genre (stuff like this) though I'm impartial as long as there's great musicianship. I'm fairly new to the HeadFi scene but I've written a few reviews on reddit on other budget ChiFi IEMs before.
Build: The full metal shell is almost identical to the T2 with minor modifications. The first notable one is that the the nozzle is slightly longer than in the T2. The second is that the back vent hole is now moved to near the MMCX connector. The third is aesthetic with the turbine backplate. Otherwise, everything is the same. The nozzle is similarly wide, the weight is the same, and the other vent hole is still right next to the nozzle.
Accessories: The stock tips are pretty decent. You get 2 sets of silicon and a set of foamies. Despite looking like SpinFits, they are NOT SpinFits sadly. One thing to note is the stock silicon tips are about 50% longer than the stock in the T2 (9mm vs. 6mm). The included over-ear cable is quite nice, a 2 core cable with a simple braid. It's fairly soft and pliable, if a little bit grippy. It does have some cable noise, but it's not too bad. Oh, you also get a premium-looking leather case. It's a bit on the bulky side IMO, more of a toss-in-your-bag rather than put-in-your-pocket type of thing.
Fit and Comfort: The T4 actually fit better than the T2. The longer nozzle and tips really help the fit as you don't need push the wide nozzle as deep into your ear to get a seal like you did with the T2. Additionally, the pre-molded over-ear cable does a good job holding up the weight of the T4s. That said, if you had major issues with the T2's fit, this might not work for you. I personally didn't have an issue with the fit.
Overall Sound Signature: A neutral bright tuning with enough bass that doesn't feel lacking yet not bassy. Bright because it is slightly treble focused and may potentially be harsh or sibilant depending on your music. The T4 is particularly clean with solid resolving ability, having an engaging and almost sterile or analytical presentation.
Bass: Bass is clearly present without being overbearing, with more of a subbass focus than a midbass one. It leans a touch towards punchy than boomy and has a fairly quick decay. Bass impact is nice and tight though nitpicking says it would be improved if it were a little more authoritative. The strength of the T4's bass is that is well controlled without a hint of muddiness or bloat while maintaining a good sense of nuance in tone. Bass lines are smooth with well-defined notes that pop off in tracks.
Mids: Thanks to the single DD, the mids stay nicely in step with the transition from bass and to treble to maintain coherency. The lower mids are very lightly elevated while the middle mids are neutral, leading to a lack of coloration here. The upper mids rise reasonably around the 2kHz mark to meet the pinna compensation similar to both the DF and Harman targets but are tamed as to not be overly strident. Instruments are presented cleanly with their natural tone coming through nicely. One instrument that stood out to me was the clarity of the snare drum timbre paired with a good dynamic response. Vocals are clearly presented without being too forward or favoring male or female vocals.
Treble: The T4 starts its treble response with a soft peak around 5kHz in the lower treble that elicits a crispness to the sound. Past this peak, the T4 maintains an elevated treble response with good treble extension. Vocals benefit from this elevated lower treble response as it brings out clarity in voices. Additionally, individual note definition is distinctly apparent in the hats and cymbals, and the T4 is able to render the delicate sound of these instruments quite well, with a crisp initial attack and clean, nuanced shimmer. Speed is not an issue. This is something many IEMs struggle with and I'm very pleased that the T4 can handle this region without trouble. Some may find it harsh or sibilant, especially if they're sensitive around that 5kHz mark or listen to music that hasn't been too well mixed. I personally don't have any problems.
Staging and Imaging: Here the T4 stops being so stellar. The staging and imaging are quite average as far as IEMs go. While it never feels congested and there is enough staging and competent imaging, it doesn't push any new boundaries and has a slight in-your-face feel that makes the T4 more engaging.
Resolution and Separation: Compared to all the other ChiFi I've reviewed in the past, the T4 is a very solid step or two above in the resolution department. I'm able to pick out extra notes or nuances in instrument timbre in many of the tracks listen to that were previously obscured in other budget IEMs. I've used the words "clean" and "clear" multiple times throughout this review and honestly, that's because the T4 is just that. Notes and chord changes are distinct and instruments are well separated. Together with it's tuning, the T4 culminates into an IEM that sounds almost sterile and analytical at times with how clean it is.
Comparisons to the Tin HiFi T2: I spent a few days listening to the T2 before I got the T4 and the constrast is fairly stark. In terms of technicalities, the T4 defeats the T2 in every way and reveals the T2's weaknesses. It has greater resolution, less graininess, and a cleaner sound. Where the T2 is able to compete on is tuning, as it has sweeter vocals and better electric guitar body thanks to the small bump in the lower mids.
Comparisons to the BLON BL-03: These two IEMs are quite different from each other. The BL-03 has relaxed and bassy tuning compared to the more engaging neutral-bright signature of the T4. The BL-03 has a softer bass response that lies more in the midbass than the tighter subbass focus of the T4. Additionally, the BL-03 also sounds more smeared out while the T4 has a much cleaner note presentation. Resolution wise, the T4 does beat out the BL-03, but the gap isn't as wide as it as it was in the T2. Staging and imaging is about the same for both. The T4 handily beats the BL-03 in the treble thanks to it's ability to manage complex hats/cymbal passages where the BL-03 cannot. However, the BL-03 does have a warmer tone that may be more enjoyable for those who are treble shy.
Should you buy it? At it's MSRP of $110, I think it's absolutely worth it. It's a very good IEM that checks almost every box for what I believe a great IEM should sound like (tuning aside). I would have to nitpick to point out flaws. If you aren't treble shy and don't need a ton of bass, the T4 may fit the bill beautifully as a starter IEM (or even ending depending on you). It's engaging and coherent with great resolution and minor flaws. I can't say what it can beat above the $100 mark but I'm confident that the T4 will be a major benchmark for the entry into midfi.
Distorted Vision
Why have they gone for crowdfunding? Never heard of Indiegogo and was about to back it until I read their Trustpilot reviews: https://uk.trustpilot.com/review/www.indiegogo.com.
I'm going to wait until I can buy them in the conventional way.

@Distorted Vision My guess is that the Indiegogo campaign is solely a form of marketing. Indiegogo (which is similar to Kickstarter) is a much larger platform than any conventional audio forum (such as HeadFi, SBAF, or reddit). Thus while Tin HiFi does not actually need the funds to manufacture the T4, they're using it as a way to reach many more customers that would have no idea about audio.

I have to say I'm envious of your selection of IEM's if you found staging average on the T4, finding my set possitively holographic straight from the box. I guess there's always scope for different fits and subjective reception of sound presentation though. Absolutely agree with your view on tonality and general resolution etc though
