Tin Hifi is one of the major and original manufacturers of affordable Hi-Fi in-ear monitor brands and have been beloved for their budget-friendly T-series and innovative P-series IEMs. Emphasizing build quality and high resolution audio playback, Tin Hifi strives to make the best of the Hi-Fi world accessible to all. You can be sure to trust Tin Hifi to make the greatest innovations in the audio market affordable and reliable.

The Next Chapter: T5​

The T series IEMs have garnered international praise for their excellent sound quality and affordability. The T5 continues on this legacy to combine the latest driver technology with excellent sound quality. The T5 utilizes the next generation of carbon drivers: DOC. In the recent few years, DLC (Diamond-Like Carbon) dynamic drivers have been popular for their fast responsiveness, achieved by their carbon material. From this foundation, Tin Hifi has engineered the next innovation in dynamic driver technology. The new 10mm DOC driver features an enhanced molecular carbon atom structure and composition that more closely mirrors that of diamond. The new structural design allows the DOC diaphragm to be thinner, while being 60% stronger and more rigid than that of traditional DLC diaphragms. Furthermore, due the closer proximity of the carbon atoms to each other, the DOC driver is 5 times harder than that of typical ceramic diaphragms.
Moreover, the physical properties of the DOC diamond diaphragm will not change even after many years of use. This feature has a great effect on the heat dissipation of the voice coil. Additional benefits of the DOC includes:
1. The DOC diamond diaphragm unit can achieve a complete linear frequency response, achieving detailed and excellent broadband and instant response, and strong dynamic contrast.
2. The DOC diamond diaphragm unit can push the split vibration frequency to a higher level, and the T5 can cover an unimaginable bandwidth range to ensure that the ideal frequency response is obtained in the two end frequency bands audible to the human ear.
3. The frequency linearity that the DOC diaphragm provides allows the mid-frequency to be completely coherent with the bass and the treble, creating a transparency in the texture and sound balance, while minimizing phase offsets.
In short, the T5 achieves an immensely punchy bass response that is combined with extremely well-extended and detailed ultra-high frequencies. The textural properties of its sound is characterized by a cohesive smoothness, linearity, and transparency across the frequency spectrum. The DOC driver is an innovation that is just as audible as it is industry-leading.

New Face​

The housing of the T5 has been constructed of aviation grade aluminum to achieve an even more refined look, as well as durability. To tune the new DOC driver, the internal cavities of the housing have been carefully designed with several unique acoustic chambers that have been mathematically calculated to achieve the perfect angles of reflection for the sound waves. Additionally, the T5 is the first of its series to utilize machine learning strategies to design the perfect shape to match that of the average human ear. Matching every curvature of the typical human ear, the fit of the T5 is ergonomic and secure, allowing long hours of listening without any discomfort. This new shape design also allows greater sound isolation, allowing you to immerse yourself in the music even when you are commuting or on the stage.

Kevlar Plated Cable​

In preparing the T5, Tin Hifi has pulled out all the stops to make it special and unique. The T5 comes stock with a 40/0.05 Oxygen Free Copper cable that is plated with 200D Kevlar to achieve complete electrical isolation for an extremely fast and clean transmission. This 4-core cable is extremely lightweight, tangle-free, and comfortable allowing you to feel as if it was cable-free.

Pros: good treble presentation, soundstage, and instrument separation, great build quality, good accessories
Cons: monotonous and poorly detailed bass, too much ear gain and presence


The TinHiFi T5 is an in-ear monitor (IEM) featuring a 10mm “DOC” dynamic driver. TinHiFi claims that DOC improves on the now-commonplace diamond-like carbon diaphragm dynamic driver type. The T5 is available at Linsoul for $129. I received the T5 from Linsoul in exchange for a fair and objective review.


I have used the TinHiFi T5 with the following sources:

  • Hidizs S9
  • Qudelix 5K
I have tested these headphones with local FLAC and Spotify Premium. Visit my last.fm page to get an idea of what I listen to.


The TinHiFi T5 comes in a large rectangular white cardboard box. This box is largely unmarked apart from TinHiFi branding on five of its six sides. There is a faintly raised pattern that spans the entire surface of the box, which I thought was a subtle yet unique touch. Inside the box, the IEMs and the included carry case are held in foam mounting sheets along with the included tips and other accessories. The package includes a detachable 2-pin cable and 14 eartips in three varieties. There are three pairs of conventional silicone eartips (S, M, L), three pairs of Sony-esque grippy black eartips with brightly colored stems (S, M, L), and one pair of TinHiFi foam eartips (M). The package also includes a small cleaning brush, a set of six replacement nozzle filters, and a tool to install them with. In terms of documentation, the T5 includes a user manual written in English and Chinese and a contact card.

The included carry case has a clamshell design with a magnetic latch. The case appears to use a presumably synthetic white leather for the bulk of its construction, with the interior surface lined with white fabric. The front of the case has a stainless steel stamp emblazoned with the TinHiFi logo. The stitching is well-done and the leather material avoids feeling cheap or tacky. One thing I did not like about the case is the top lip of the bottom half, which blocks off roughly a third of the case volume around the edges. It would have made more sense to me to omit this lip to make it easier to stow the IEMs.


The TinHiFi T5 uses a three-part shell design consisting of a faceplate, upper housing, and lower housing. Each shell component is built with gunmetal grey aluminum, polished to a near-mirror sheen. The teardrop-shaped faceplate is set into the top half of the housing body. The text “TINHiFi” is etched into each of the faceplates. The housing as a whole has an ergonomic, pseudo-custom fit. “L” and “R” indicators are marked in white in the center of the ear-facing surface of the lower housing. There is a small circular vent on the top of the upper housing as well as on the bottom housing, slightly offset from the nozzle. The T5 has brass nozzles with perforated metal mesh nozzle covers and sizable lips for securing eartips. The recessed 2-pin connector housing is bisected by the seam between the upper and lower housings.

The oxygen-free cable included with the T5 is light, flexible, and not prone to tangling. The cable strands are wrapped in a spiral pattern below the Y-split and follow a double helix pattern above it. The straight 3.5mm jack hardware, the Y-split hardware, and the greatly appreciated chin-adjustment slider are also made from a shiny gunmetal grey aluminum that matches the housing materials. There is strain relief above the jack but not at the Y-split. The 2-pin housings have “L” and “R” indicators printed in white, and the Y-split hardware is marked with the TinHiFi logo. The cable has pre-formed clear plastic earguides.


The TinHiFi T5 is intended to be worn cable-up. They have a shallow insertion depth, and I found them to be extremely comfortable to wear for extended periods. I did not have issues with the housings migrating out of my ears with the included foam eartips. Isolation is below average. There is very slight driver flex even with foam eartips.


My measurements, including those referenced in this review, can be found on my expanding squig.link database:


My measurements were conducted with a Dayton iMM-6 microphone using a vinyl tubing coupler and a calibrated USB sound interface. The measurements use a compensation file derived from relating my raw measurements to published measurements from Crinacle and Antdroid. The measurements are presented with 1/24th smoothing. There is a resonant peak at 8k. Measurements above 10 kHz are not reliable. These measurements were taken with the stock small-sized silicone eartips.


Note: My impressions are based on use with the included pair of foam eartips.

The TinHiFi T5 is a bright-sounding IEM with a broadly elevated bass response.

The TinHiFi T5’s bass tuning is somewhere between a mid-bass hump and a sub-bass shelf, but more closely resembles the first. However, the T5’s tuning produces none of the benefits of fully committing to either approach. There is not enough sub-bass or mid-bass to produce visceral rumble or tangible slam. Instead, the T5 generates sonic mud. There is an appalling lack of internal resolution in the bass response for an IEM above the $100 price point. While musical notes are distinct from each other, and the T5’s instrument separation and soundstage size are impressive overall, there is little insight into the character of individual notes. The T5’s bass has little texture. The speed at which notes are delivered is adequate for faster musical passages, but they arrive with an unsatisfying thud.

While not congested, the TinHiFi T5 has a thin, tinny midrange that suffers from both shout and shrillness. There is little warmth or body in the lower midrange, and the overall character of the T5’s midrange is somewhere between chilly and frigid. Vocal intelligibility is excellent for both male and female vocals. However, female vocals are too far forward and easily transgress the boundary between vibrancy and sibilance. Similarly, while midrange clarity is excellent, the presence region is perforated by a harsh peak which makes electronic music in particular difficult to endure without discomfort. Male vocal intelligibility can suffer during busy musical passages but remains adequate in most cases. Timbre is a mixed bag. There is a hint of metallic harshness throughout the T5’s frequency response, but I suspect this is related to the IEM’s frequency response and not the intrinsic qualities of its driver.

The TinHiFi T5’s treble is the least troubled segment of its frequency response. It seems to fall evenly from the presence region without presenting any egregious peaks and is well balanced against the elevated upper midrange. It is crisp and detailed without being harsh to my ears. There is a bit of extra energy around 10 kHz that gives cymbals some additional splash. This may cross the line into artificiality for some, as it is worth noting I prefer more mid-treble emphasis than many. There is a healthy amount of air, and transient delivery seems realistic. Imaging is adequate.


TinHiFi T5 ($129) vs TinHiFi T2 Plus ($53.99)

The TinHiFi T2 Plus is easier to listen to with a wider variety of musical genres than the T5. This is primarily due to its more restrained upper midrange. The T2 Plus avoids the shout and shrillness of the T5 but is too restrained in terms of ear gain for my tastes. Vocals sound a bit flat to my ears with the T2 Plus, especially after switching from the T5. The T5 offers much greater vocal clarity and intelligibility than the T2 Plus, though this comes with the costs I described earlier. Ideally, I would prefer something in between the two IEMS in terms of ear gain and presence. The T2 Plus has better internal bass note resolution and texture than the T5, whereas the T5 has more detailed and resolving treble. Interestingly, the T5 does not exhibit the treble ringing phenomenon I sometimes experienced with the T2 Plus. The T2 Plus has a less noticeably metallic timbre than the T5. The T5 offers slightly better soundstage width than the T2 Plus, but vastly greater soundstage depth and instrument separation.

TinHiFi T5 ($129) vs Moondrop Aria ($79.99)​

The Moondrop Aria more closely approximates the Harman target than the TinHiFi T5, with a greater emphasis on sub-bass and a more deliberate upper midrange presentation. The greater sub-bass emphasis combined with the absence of the T5’s extreme presence peak makes the Aria a much better choice for electronic music. The Aria’s upper midrange is also much smoother than the T5’s while retaining a healthy amount of ear gain. Female vocals come across as more evenly balanced with the rest of the frequency response on the Aria. The T5 has more sparkle and less air than the Aria. The T5 has a larger soundstage than the Aria but worse instrument separation and imaging. The T5 has more premium construction and a better-fitting shell design. I also prefer the T5’s included cable to the one included with the Aria.


The TinHiFi T5 can be readily driven with modest sources. I did not notice hiss with any of my sources.


The TinHiFi T5 is uncompetitive at its price point and fails to definitively eclipse more affordable models within TinHiFi’s own lineup. Not recommended.

The TinHiFi T5 can be purchased below:

TinHiFi T5 New Innovation — DOC Dynamic Driver In Ear Earphones — Linsoul Audio


Headphoneus Supremus
When too much is like not enough
Pros: Soundstage size, Transparent'ish Layering, Construction
Cons: Wacky tonal balance, uncontrolled technicalities, uneven musicality, low sound value


Decent clarity, decent holographic layering, Big soundstage, Good construction

CONS: Boomy resonant bass that lack body and definition, artificial timbre, lack of attack edge and snap (shouty), thin vocal-mids, unbalanced treble, price value, not versatile 2pin connector



It look like TinHifi launch a new IEM every 2months lately, and while the T2+ wasn't completely nailing my tonal target in term of clean immersive dynamic, it sure was a well-tuned and cohesive sound.
For 60$.
Now the expectation bar as set way higher with the new TinHifi T5 which sell for 140$, a price range filled by great offering like BQEYZ Spring2, FIIO FH3, IKKO OH1.

Another thing that pumps up my expectation was the use of a new 10mm DOC Dynamic Driver which is supposed to be an improved DLC (Diamond-Like-Carbon) Diaphragm made of improved molecular carbon that make the diaphragm thinner but 60% more solid and sturdy than typical DLC. While this is very exciting, it's the first-gen of new patented technology and we don't know anything about the flexibility of the material. As well, how this driver will be implemented in the big acoustic housing of T5 will sure interfere with its final rendering. One thing sure, Tinhifi promises a lot of advantages with this driver but....

Let's see in this review how the whole thing sounds to my ears.


The construction seem robust, its made of ''aviation grade aluminum'' which is surprisingly light. The 2pin connection is a little too deep in the housing, making it hard to pair it with different cable. Talking of cable, T5 have a kevlar reinforced cable and promise best sound transmission, in my hands it seem like an average quality cable and i wouldhave love to change it but I can't.


The Design, while not particularly sexy for they eyes, neither ugly or cheap looking, have a unique ''universal ear shape'' that Tinhifi achieve with machine learning process, interestingly, it work well because those are very organically shape and fit my ears easily even if the housing is big.

189163616_810659546555735_2683502871402904538_n (1).jpg


T5 has a warmed W shape sound signature, with boosted resonant bass, bit recessed mid-range with rolled off lower mid and slightly shouty treble. The bass has a strange rubbery slam that can bloom mids with its uncontrolled resonance, making it light but boomy in impact, lacking proper weight and roundness and unbalancing overall sound with it’s distracting uneven presence. Bass doesn't have proper articulation and is the worst part of T5 sound spectrum. The mids are a bit hollow in definition edge and impact, thin and dry, but with good transparency and clarity when bass doesnt bloom it. The treble is a bit unbalanced and artificial, it can go splashy without going harsh, with tamed crunchiness and a lack of sparkle-decay.

The soundstage is wide and tall and Imaging has good numbers of sound layers. Highs can dig some micro-details.
Attack lack control everywhere but in upper treble, bass attack is slow and uncontrolled, imaging is unrealistic, background isn’t clean, upper mids can create sibilance lacking in snap, weightless sound, harmonic distortion is high

It doesn’t have a good amount of density and pitch contour, has a strange texture with an emphasis in the higher pitch (lower-mid treble) so you got uneven micro-details in it that seems out of place, can create slight sibilance. Dry, thin and artificially brighten.

The TinHifi T5 just can’t trigger any emotionality in me, its musicality is what i would describe as dry, boomy and resonant and while burn in do improve slightly bass response, it still sounds plain wrong with its reverberant extension that has an overly excited artificial slam. Whatever I listen too it sounds wrong, except for a few indie rock and folk tracks that haven't kick drum either bass in it. The soundstage is impressive in size, but what's inside it isn't.

Ear tips include are good enough and interferes minimally the sound representation due to the fact the DD driver isn’t placed in front of the nozzle but at its side pointing in an angular direction. For the cables, i don’t know because the 2pin connector is too deep to permit any of the cables i have to be used. It seems T5 doesn’t scale up with amping, but it sure doesn’t want a warm bassy audio source because the sound will be super muddy-hollow. Simply put: nothing can save T5 from its tonal imbalance and meshed-up technicalities.



VS VSONIC VS7 (single DD-140$)

VS7 is more balance even if similar in tonality, with notably less, boosted and boomy bass, cleaner less sibilant mids and sharper bit treblier highs. Imaging is cleaner, more precise and with more air between instruments. While not perfect, it sounds way more refined and balanced than T5 which has a more shouty sound, with unnatural tonality-timbre, and notably less snappy attack. T5 being more excited W shape in signature and forwards yet hollow in presentation, the vocal has more sibilance and wacky lips noise or piece of instrument texture, silence is hard to found due to lot of post-attack reverberance...instrument sound dryer more artificial even if VS7 isnt a very natural sound IEM.
Here, T5 lose in both technicalities and tonal balance.

VS NFaudio NM2+ (single DD-180$)
NM2+ is more bright mid-centric, with lusher, fuller wider and more fowards mids-vocal. Bass is better controlled, have more roundness and weight, bassline sound like it kinda should while T5 sound like a cranked defective sub stock in a hall. The soundstage of T5 is a bit wider deeper, transparency too is bit better due to oversaturated texturing of NM2+. Tonality is more cohesive and less artificial than T5. Attack is a bit more edge but treble has less bite-decay. NM2+ sound too fowards while T5 too distant. So at the end, both are bad and I don't know who win...NM2+ for bit fuller more balanced tonality?

VS TINHFI T2+ (50$)

Tonality is notably more balanced and natural, with fuller timbre, more weight in the attack. Its more relaxed yet more snappy in attack. The soundstage is a bit more intimate and less airy, imaging is more realistic but compressed. T2+ is L shape vs W shape of T5. Whatever the instrument, it sounds more life-like with T2+. Vocal has a more natural body and, unlike T5, no sibilance or lipsy timbre.
At near 3 times the price, T5 is near 3 times inferior to T2+. Tonality and uncontrolled attack being the biggest flaws as well as boomy resonant bass.



Saying Tinhifi is inconsistent with is offering is an oxymoron. In that regard, they are a bit similar to a company like Kbear that seems like a big experimental audio lab that tests random tuning and ideas without a comprehensive vision of what balanced tonality means to them. It’s hard to find a connection between T line up IEM apart the letter and the T5 is the one that feels the most out of place with its wacky resonant tonality. The T2 and T2+ both offer a more cohesive, realist sound with a higher level of musical enjoyment. And even if they weren’t 3 times cheaper than T5, they sure would represent a higher sound value.

Tin HiFi T5 -The Best from Tin HiFi !



This unit was supplied to me by Tin HiFi for the purpose of an honest review. Everything mentioned in this review are purely my own based on my experiences with the IEM.


Tin HiFi is an emerging Chinese based audio Brand who have produced quite a few audio gears within the $20 to $350 price range. Their sound signature is quite well known to the masses and I have also used 2-3 of their products myself starting with the original Tin T2. T5 is their latest iteration and in the $100-120 category it seems quite promising with great looks and promises to deliver even better sound. Let's see what they have been up to with the T5.


Specifications are as below:

Driver Unit: 10mm DOC Driver
Sensitivity: 103dB ±1dB @1kHz 0.126V
Frequency Response: 10-20kHz
Impedance: 48Ω±15%
Rated/Max Power: 3/4mW
Max Distortion: 1%@1kHz 0.126V
Interface: Gold-plated 2P connector
Plug: 3.5mm black glue gold plated plug
Conductor/Cable: 2.8mm (40/0.05 oxygen free copper +200D Kevlar)* 4 - core Black PU cable L=1.25m
Housing Color: Titanium grey



Following items are found in the package:
  • Tin HiFi T5 earphones
  • 2 Pin Cable
  • Faux leather carrying case
  • 6 replaceable nozzle mesh filters
  • Nozzle removal tool
  • Cleaning brush
  • 6 pairs of silicone ear-tips
  • 1 pair of foam ear-tips


Design & Build Quality:

Looks are always subjective, but I think these are great-looking IEM, that’s both striking and ergonomic. The outer shell is made out of titanium for an even more solid appearance. The added durability is also a positive attribute. The shape of the IEM is nice & universal fit that and provides a comfortable fit for most listeners. In my experience with the T5, the earphones achieved a standard level of comfort. Sometimes the body can feel a little larger and heavier but nothing of significant discomfort at all.


The Stock Cable:

The cable this time around is much improved than all previous Tin HiFi stock cables. it looks nice and also performs well.

Amp-ing Requirements:

I have found that this IEM can perform well without any amping at all while being directly connected to devices such as: iPad, iPhone, etc..
However, this IEM really shines when paired with a good and powerful DAC/AMP.


Items used for this review:

Shanling UA2, IFI Micro IDSD Black Label Signature
DAP/Source : Fiio M3 Pro, Laptop & iPad
Streaming Source: QOBUZ

Upgrade Cable: Following upgrade cables used to see how FH5S fares with different types of cables:
- CEMA Electro Acousti 6N OCC + OCC Silver plating 26AWG single crystal copper cable with balanced 4.4mm connector
- CEMA Electro Acousti 22AWG 7N type6 advanced pure silver cable with balanced 4.4mm connector

Ear Tips: Final E series Clear red tips

Tracks Used:
The tracks I have used can be found from the below playlist that I have used and generally use for most reviews...

Let's now talk about the quality of Sound....


Bass felt fast and punchy. These is good texture & air in the bass. the punch & thump is there with a good amount of muscle but nothing overwhelming.
Overall good performance in Bass I would say.


Midrange is less pronounced due to the V-shaped sound of this IEM. Nevertheless, it's not like anything is missing. Mids are good with texture. Vocals sound natural.
However, micro details in the mids section seemed somewhat less pronounced.

The Treble:

Treble seems just great. textured and airy. No peaks found anywhere. Though the graph shows few peaks in tge treble region - I found the treble to be not fatiguing and enjoyable.


Soundstage has good width and depth and can be considered as slightly above average for the price.

Imaging & Timbre:

Sense of direction is quite good and the sound is quite natural hence I would say that this IEM has good imaging & timbre for the price.
However, in terms of micro details retrieval - I found this IEM is to be a bit lacking.

Comparisons :

Tin HiFi T5 vs BQEYZ Summer :

The BQEYZ Summer is the latest release from BQEYZ and comes at the same price points - and hence despite the differences in specs can be considered as direct competitors.


Build & Comfort: The BQEYZ Summer comes with resin build which feels non-premium unlike the Tin HiFi T5 which comes in titanium with Gunmetal type finish and feels very premium. However, in terms of comfort, I would hands down prefer the BQEYZ Summer for longer listening sessions over the Tin HiFi T5 which is slightly heavier and bigger.


Bass: When it comes to bass, the BQEYZ Summer excels in terms of details reteieval and air in the sub bass region while the Tin Hifi T5 seems to have more thump.
The BQEYZ seems to have better depth in bass than the Tin HiFi T5

Mids: I found the Mids on the BQEYZ summer to be much more detailed, textured. This is where the weakness shows in Tin HiFi T5. The Mids have more layering and muscle in the BQEYZ Summer.

Treble: This is where the Tin HiFi T5 really excels with it's non-fatiguing sound signature. The BQEYZ though has good amount of details and texture and layering and to some extent better details than the Tin HiFi T5, it has few peaks in the treble region which acts as Achilles hill for them.

Soundstage & Timbre: BQEYZ Summer has better soundstage both in terms of width & depth than the Tin HiFi T5. It has much better micro details retrieval and texture and hence timbre is also better in the BQEYZ Summer.

Conclusion :
Having said all that - both IEMs have their goods and bad and each excels in their own area of strength. The Tin HiFi T5 has better overall sound than the previous T4 and can be considered the best performing Tin HiFi IEM till date.
