TinHiFi​

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.

TinHiFi T5: Missed the Memo
Pros: Ergonomics and material quality - Clarity and detail - Soundstage
Cons: Bright sound can be fatiguing - Large earpieces might be a challenge for smaller ears
Greetings!

Today we're checking out TinHiFi's newest entry into their ever popular T-Series of earphones.

TinHiFi's claim to fame is the original T2, a reference quality dual-dynamic earphone that didn't break the bank. Since it's release in 2017 put them on the map, TinHiFi's lineup has been fleshed out with a wide variety of products, some great like the T2+, some lacking like the true wireless T2000.

When the T5 was announced, I was pumped for the gorgeous new shell design, the move to a 2-pin system, and the inclusion of super stiff DOC single dynamic drivers. It sounded like it was going to be a killer release. Since I wasn't expecting the opportunity to review it, I scoped the usual suspects once reviews dropped and was shocked to see it being almost universally panned. Once that happened, I knew I needed to hear it for myself and reached out to TinHiFi to see if they would be willing to provide a sample. You're reading this so you know how that went.

I've had it in hand and in the ear since early May with listening interspersed with a variety of much more expensive, top of the line products. Clearly I missed some important anti-T5 memo sent to my peers because the T5 is absolutely fantastic. Let's take a closer look, shall we?

P5070009.JPGP5070010.JPGP5070011.JPG

What I Hear Bass from the T5 is sub-bass biased with a lean mid-bass region. This leaves it with a cooler tonality. It has plenty of snap and attack to notes and if quite nimble and quick, easily tackling Havok's 'Time Is Up' album with ease. Texturing is good but not class leading with grungy notes from The Prodigy and Tobacco being satisfactorily replicated. A bit more grit would be nice, but then it would probably end up being even more polarizing so this is fine. Quantity is certainly above neutral, but far from basshead, or even bass-focused. If you're familiar with the T4 or T2 Plus, expect a presentation in line with those, but with less mid-bass.

The lower midrange is pretty much in line with the low end in terms of emphasis, with a prominent rise in the upper mids. While this boost does result in a strong presence for rhythm instruments that some will undoubtedly find fatiguing, this is right up my alley and in line with what I enjoy from other upper-mid boosted iems like the Moondrop SSR/SSP, Meze 12 Classics V2, Meze Rai Solo, among others. I love the way vocals are clear and prominent with amazing clarity and coherence, though deeper vocalists come across more natural. Those with a softer, warmer tonality would benefit from a mid-bass boost the added warmth that would bring.

With a presence region bias that gives the T5 it's near class leading clarity and detail, you'd be excused for thinking they'd kill the brilliance region. Nope. A mild 7k peak is present giving the T5 plenty of sparkle and shimmer to go along with all that detail. The lean note weight present in the low end of course carries through to this region too which results in plenty of air and space between notes. The T5 is also plenty speedy in this region with notes hitting hard and decaying fairly quickly. I have no issues tossing King Crimson's various, improvisation-heavy, jazz-addled tracks at it. Given all the emphasis going on up here, know this is a bright earphone. If you don't like the sound of that, this one probably isn't for you and you'd be better off with Dunu's SA3, the Moondrop Starfield, or even BGVP's underappreciated DMS.

When it comes to sound stage, I'm quite satisfied with the T5. Wider and deeper than average, it can very easily surround you with your music. Vocals have a semi-intimate default location, sitting just outside the inner ear. This still leaves room for closed in moments like the trailing vocals of Culprate's “Undefined” to sidle over uncomfortably close, and for the sounds of shells ricocheting off a tank's hull to careen off into the distance when playing World of Tanks. It's also awesome with film since you can become completely immersed in the impressive sound design of most modern epics. When it comes to technical qualities, the T5 doesn't lead the pack, but it's far from a slacker. Imaging is reasonably smooth with it's channel-to-channel movements, lacking the precision of multi-driver models like the BQEYZ Summer and Brainwavz B400. The wonderful depth of the staging allows layered tracks to appropriately space out, and for individual instruments to remain well-separated. At really high volumes these qualities falter somewhat, but you shouldn't be listening that loud anyway. Unless of course you don't care a bout your future hearing. In that case, go wild.

Overall, a pretty damn awesome earphone. Intoxicating sub-bass, amazing detail and clarity, and a spacious sound stage serve it well, while the general brightness and lack of warmth will turn some off. This is one I use all the time, so clearly none of those subjective negatives are of a concern to me.

TinHiFi T5.jpgTinHiFi T5 & Friends.jpg

Compared To A Peer (volumes matched with a Dayton iMM-6)

BQEYZ Summer (129.00 USD): The single-dynamic T5 has less bass emphasis with a more linear transition into the lower mids than the tribrid Summer. It sounds less meaty, cooler, and more lean than the notably bassier Summer. The T5 comes across a bit speedier with similar texturing. The midrange of the Summer peaks just before 2k then slowly tapers down as you head into the treble whereas the T5 peaks around 2.5k then remains fairly even in emphasis until you slip into the presence region. These differences result in the T5 being considerably more detailed and crisp, but it comes at the expense of note weight and some realism. The Summer's timbre and vocal reproduction are more full-bodied and natural. Treble on the two is quite different with the T5's presence region bias giving it a huge advantage in detail retrieval and general clarity. The Summer pulls this regions back in favour of a ~7k treble peak resulting in a more sparkly but distant presentation. Both earphones have a good sound stage with the T5's coming across deeper and more layered. Imaging is a touch tighter on the Summer, but they're both quite competent.

Overall I find both extremely enjoyable, though the T5 fits in more with my preferences for less bass and an upper mid push. I also appreciate the smattering of detail it outputs, though the Summer isn't a slouch by any means. If you prefer a thicker, warmer, bassier, more natural presentation, the Summer will be the better choice.

Dunu SA3 (139.99 USD): Bass from the SA3 has a slower, thicker feel to it with a more linear and even run from sub- to upper-bass regions. It lacks the visceral feedback on the deepest of notes, and isn't quite as nimble nor competent with congested passages. Heading into the mids the SA3 peaks earlier around 1.75k with a soft transition into a minor 3k peak, after which things take a strong drop into the treble region. In comparison, the T5 peaks later, around 2.5k, then continues to rise in emphasis as we head into the treble. This gives it a leaner, brighter presentation with a much snappier attack than the SA3, in addition to much more crisp and clear vocals. While timbre on neither is perfect, the SA3 gets the nod. While both products place a focus on the presence region over the brilliance region, the T5's ~5k peak happens about 15dB higher than the SA3's, which is also more of a mild plateau than a peak. Peaks occur again around 7k, with the T5's occurring a mere 10dB higher this time. These two vastly different presentations give each earphone their own unique presentations. The T5 is quite a bit more vibrant and detailed with technical chops the SA3 can't match. These technical advantages carry over to the T5's sound stage which is considerably wider and deeper. Thanks to the improved layering and separation qualities of the T5, the SA3 falls behind on congested tracks leaving it better suited to less complicated passages. Imaging on the SA3 is similar, with precise enough channel-to-channel movements.

Overall I much prefer the T5. I like a bright, vibrant earphone with prominent upper mids and the T5 is just that. While it's not as natural sounding or relaxing over long listening sessions, the T5's technical advantages are too much to ignore, as swapping between the two leaves my wholly underwhelmed with the SA3. If you prefer a more relaxing sound, obviously the SA3 will be a better choice for you.

In The Ear The T5 features a completely new shell design for the brand, and I'm completely on board. Gone is the awkward over ear bullet design of past T-Series models (T2 Plus excepted). In place of this is an extremely well thought out, highly ergonomic low profile design that makes this TinHiFi's best shell yet, in my humble opinion of course.

As is standard for the brand, build quality is quite good. The aluminum shells are very neatly crafted with smooth curves, a clean, brushed face plate and subtle branding. On the inner sides of each ear piece are laser etched left and right indicators. Up top are deeply recessed ports to accommodate a 0.78mm 2-pin system. I'm very glad Tin has decided to move away from MMCX with this model since so many customers have had problems with it in the past. Fit and finish is generally quite good with just the slightest misalignment of the main components leaving the otherwise extremely tight seams more pronounced than they otherwise would be. It's nothing that will cause any discomfort, it's just not perfection. I can forgive a brand for falling short of perfection.

The cable is another winner in my opinion. It reminds me of the types of cables TFZ and TRN include with some of their products, but without the sticky, bouncy sheath of the former, and annoying memory of bends and twists inherent to the latter. Advertising likes to pitch the Kevlar plating that should in theory help with overall durability, but who really knows since the T5 hasn't been out that long. Strain relief is minimal at best with a small, but fairly soft relief present at the straight jack, none present at the y-split, and preformed guides carrying double duty leading into the earpieces. That Kevlar will have it's work cut out for it if it's going to keep this cable alive at the typical failure points. Sheath aside, the hardware TinHiFi uses is excellent. The straight jack is surrounding in two bands of fine knurling which not only looks nice, but provides plenty of grip. The tiny metal y-split has the TinHiFi logo laser-etched into it so it won't wear off over time. I can overlook the lack of relief since they opted to include a chin cinch. While it's a little more loose than I prefer, and can be forced out of position with relative ease, it works well enough to warrant being included. Last but not least, the tiny metal 2-pin plugs have the channels marked with L/R and colour coded plastics, meaning there is no excuse for a user to plug them in incorrectly. Overall an awesome cable in use, but boring to look at thanks to the plain black sheath and tight twist that must be looked at up close to truly appreciate. Not a cable I'll be swapping out anytime soon.

Comfort is where the T5 is a step over everything else TinHiFi has released in the past, at least for me. The size will be a hurdle for this with smaller ears, but for everyone else it should be just right. It has soft curves, a short nozzle, and excellent weight distribution, all qualities that result in a product that can be worn for long periods without any discomfort. I have used the T5 for hours on end multiple times without any need to adjust the fit or take a break due to physical discomfort. It also isolates really quite well with the included tips, silicone or otherwise. I have no issues using it out and about in loud areas, though when using silicone tips a slight bump in volume is needed around construction sites and screaming children.

In The Box The T5 comes in a large, vibrant white, textured box. One neat detail that will likely be overlooked is the embossed TinHiFi logo pattern that makes up the texturing. On the front of the package you find the usual branding and model information. Flipping to the back you won't find a list of contents, specifications, measurements, or much information at all really. Beyond some QR codes for their website and social media platforms, all that is present is a retail bar code and where the T5 was made. Lifting off the lid you are greeted to a sizable, bright white carrying case and the T5's earpieces safely tucked in shaped foam cutouts. Lifting the insert in which the earpieces are set, you find a user manual in various languages, a social media card, some ear tips, and other accessories. In all you get:
  • T5 earphones
  • 0.78mm 2-pin 4-core cable with 40/0.05 high-purity Oxygen-Free-Copper cable with Kevlar 200D plating
  • Carrying case
  • Sony Hybrid-like single flange tips (s/m/l)
  • Spintfit-like single flange tips (s/m/l)
  • Foam tips (m)
  • Spare filters (3 pairs)
  • Tweezers
  • Cleaning brush
Overall a very premium unboxing. I was quite impressed. The modern, minimalist design and white colour scheme looks classy and the simulated scent of leather given of by the case smells nice. All of the accessories have a purpose. The case definitely gives off the impression you're getting a more expensive product than you are. It's a bit too large for anything but a jacket pocket or bag, but the construction is top tier. It has neat stitching and a metal TinHIFI badge, along with a spacious padded interior that can accommodate the earphones, some spare tips, and a compact DAP like the Shanling M0 and/or type-C dongle like the VE Odyssey HD. It's a wonderful case.

The included tips are also worth a mention. The Sony hybrid style tips are stiffer than the real deal, but they still work well. The same or very similar tips have been included with some Kinera products. Unlike Sony's tips, they hold up extremely well over time and are not at all fragile. While the hybrids are good tips, it's the Spinfit-like tips that really caught my attention. They feature a similar pivoting design between the shaft and flange, but unlike Spinfits are a standard tip length. I found they provided an impressively reliable seal along with outstanding comfort. These are something I'd buy a bunch of and use with quite a few different earphones, they're that good.

Final Thoughts With the T5 TinHiFi has released something that is apparently polarizing. I'm taking the side of it being a good release and have no issues recommending it. If you like earphones with a sub-bass over mid-bass bias, and can appreciate the decision to highlight clarity and detail over absolute tonal accuracy, or just like a brighter sounding product, then check out the T5. It's both fun and technical. The new shell looks fantastic and has some of the best ergonomics to cross my path, and it comes with a well appointed accessory kit. This slots in as a personal favourite and is something I will continue to use long after this review has been posted and the next new hotness has become long forgotten. I'd give it a higher score but 4 stars will already trigger enough people, so, 4 it is.

Great job TinHiFi. Keep releasing products that cater to a variety of customer preferences, even if it doesn't make you a ton of money. It'll earn you respect, something that can't be bought.

Thanks for the “alternative” view on the T5. This is exactly why you can’t look at a graph and say, “oooh, I don’t like that.” Nicely done.

I would like to thank DD-Audio Store for providing a review unit of the T5. Rest assured that my impressions written in this review are my own personal thoughts and opinions and in no way influenced by outside parties.

I am not an expert in this hobby nor claim to be an audiophile. I just love listening to music and am fond of writing articles.



Introduction:


The TIN HiFi T5 is the latest release from the audio company. Utilizing a single 10mm “DOC” dynamic driver, the technology is advertised as an evolution of the DLC drivers people have come to love. I don’t know if that’s just random marketing “facts” or something, but spoiler alert – they don’t sound particularly exceptional. Currently selling for 129 USD, it has a sensitivity of 103 dB with an unusually high impedance for an IEM at 48 ohms.

These were plugged to my Oppo Reno 4/Asus X409 with the Earstudio HUD100 MK2 (bypass, high power) for the review. While the impedance says otherwise, there were no observed improvements with more power. A phone will do.

IMG20210627114210.jpg



Build and Comfort: Exceptional build. On their page, it says that the shell’s made of aviation-grade aluminum and it feels awesome on hand. Shell is of the bigger side but has cuts that contour to the human ear.

Regarding fit, looks can be deceiving, and that is the case with the T5. It fits surprisingly well in my small Asian ears, doesn’t feel heavy at all, nor fits big where you will always know that it’s there. One of the best-fitting IEM I have.

Nozzle is of below average length and average width. It did fit all eartips in my possession and I didn’t encounter any issues with the nozzle design.

The stock cable is a 4-core, Kevlar-reinforced cable with a twisted design. In my considerably short audio journey, I’ve found twisted stock cables to be rarer compared to the more commonly included braided ones. Handles well though is on the thinner side. Connectors, jack, splitter, and slider (sometimes works) are all made of metal.

Isolation is below-average. Basically consider it non-existent for an IEM especially of this size. Earbud-like isolation.


Package: 3 pairs of colored stem silicone tips (S/M/L). 3 pairs of translucent grey “spinning” silicone tips (S/M/L). 1 pair of foam tips (M). Faux-leather carrying case. Paperwork. Cleaning brush. 3 pairs of nozzle filters. Filter application tool. 4-core cable.


IMG20210627114254.jpg



Now, onto sound:

For this review, the IEM was left in stock mode, without mods using the BQEYZ Summer vocal tips (any eartip advertised as vocal-enhancing will do) with a low listening volume low.

----------

Bass:
elevated tuning. Sub-par detail and extension. Close to non-existent texture. Tonality leans slightly towards mid-bass over sub-bass. Sub-bass, while present, is like a trickle (no rumble felt at all). Unacceptable for the price it sells for. IT BLOOMS. Due to the bass quality concerning speed (unacceptably slow) and tightness, it has a more-than-usual tendency to present monotonous bass lines – smeared and woolly. Bass bleed manifests a lot. Worst aspect of the T5.

Midrange: they alright… if it was selling for 30 USD. The upper midrange elevation leads to a shouty presentation at higher volumes, with a significant lower-to-mid treble peak adding to that (can’t turn up the volume; maintain at low volume listen). Slightly recessed midrange overall (excluding quite shouty upper midrange), which does add to the stage presentation. Resolution is average. Midrange proper sounds thin and harsh (can’t go more than 1.5 hours). Male vocals get eaten by the bass response.

Treble: “most inoffensive” part of the T5’s sound when compared to the other regions. Decent air, clarity and control (though does almost cross the splashy border). BUT it is exceptionally *chef’s kiss* peaky in ear, which become unbearable in longer listen (same experience with EDX; peakier with stock tips). Really, really close to being sibilant for my ears/tolerance. Listening to badly recorded tracks is quite the torture from the highs department with the T5.

----------

Timbre:
The DOC driver utilized in the T5 sounds particularly dry with a tendency to be thin and artificial.

Soundstage, Imaging, and Separation: The stage immerses the listener inside this huge world. Though it is absolutely unnatural, the presentation is, for lack of a better word, quite magical. The feeling is like freediving – where the individual is engulfed in this unexplainably vast and deep space. I’m attributing this trait to the large chamber thanks to the huge shell as well as the non-existent isolation. Imaging does well in presenting spatial location of sound/s. HOWEVER, the other half of the presentation – separation, falls short. While it does image well, its instrument separation capabilities cannot fully utilize the remarkable soundstage, most especially when things get even the slightest busy. The driver cannot handle multiple instruments and the space between instruments blur and go over each other.

Detail-retrieval: nothing exceptional. Macro and microdetail is present but doesn’t jump at you. You have to specifically look for it to notice.

----------

Conclusion:



The unboxing experience was very premium-feeling. The box has debossed print literally all over it, which look like they were made as the product box of a designer brand. The IEM itself feels like a 200+ USD product on hand. But the most important aspect in this hobby fails real hard. If I were to conclude the SQ, I’d say it’s decent… if it was sold for 30 USD. The only special thing it does in the price bracket it unjustifiably lives in is soundstage. But then again, who buys a 129 USD IEM for its soundstage when everything else fails?

INTRODUCTION AND DISCLAIMER:

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.

SOURCES:​

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.

PACKAGING AND ACCESSORIES:

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.

BUILD QUALITY AND DESIGN:

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.

COMFORT, FIT, AND ISOLATION:

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.

MEASUREMENTS:

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

https://bedrock.squig.link/

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.

SOUND:

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.

COMPARISONS:

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.

AMPLIFICATION REQUIREMENTS AND SOURCE PAIRING:

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

CLOSING WORDS:

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