TINHIFI T1S Universal In-Ear Monitor

INTRODUCTION:

Tin HiFi, the brand based out of China is a well renowned brand among the audiophiles for its amazing audio products. The team has their In House sound signature which one can hear via the older products like the T2, T4 etc.. The planar driver earphones still follow their in house curve while the budget products from Tin HiFi are turning towards general consumer oriented sound signature to capture the budget market. The T3 Plus is an example for the success and to continue their strike in the budget market they have launched this T1S as a successor to the T1 Plus and in this review let’s check out how good this is in the current times.



SPECIFICATIONS:

Configuration: Beryllium Plated Diaphragm dynamic driver

Pin Type: 0.78mm 2 PIN

Colors: White, pink, black, and green

DISCLAIMER:

This unit has been provided to me by Tin HiFi to review out. The whole views are based on my observations with this product and it might differ from person to person based on their pairing and sources.

If you are interested in purchasing this product then please go ahead with this unaffiliated link: Here

DESIGN AND FIT:

The whole construction is made out of plastic but well built with nice sturdy finish overall. The body is transparent which allows the components to be seen via the naked eye while the faceplate is coloured to give a style to the IEM.

The QDC connector feels sturdy but can feel the tightness while inserting the cable. The stock cable is good and it's a silver plated cable. The braiding feels good but definitely not to the level of premium. The cable feels neither soft nor hard on hands, rather it's ok in terms of supple nature.

The provided stock tips does provide nice seal and isolation overall hence the after market tips are not required for the most part.



SOUND:

The sound profile of this product is more on the balanced side which is pretty interesting since most of the budget products do have that traditional V shaped sound. Initially I thought that this product was going to have that mediocre v shaped sound with a more warmish tone but the T1S really surprised me in that aspect.

The overall tonality of this product is pretty smooth and balanced accompanying the overall signature too. The bass is on the heavier side while the midrange and the treble are on the balanced aspect. Technicalities being on the above average side, this really brings up some heat to this budget competition. Let’s discuss the sound in detail in the following sections.

BASS:

The bass in the T1S is pretty prominent and the most instantly striking feature during your initial listening periods. The amount of the bass here in the T1S is more on the pronounced side. The mid bass takes up the center stage hence the sub bass might feel weaker in presence. The quality is pretty good too and I will see in detail.

SUB BASS: It’s good but due to that bigger mid bass presence the sub bass gets lost in the background most of the time. The bass being bigger, lost its track on the control aspect. The sub bass reaches deep enough and creates some good rumbles but their presence gets masked by the mid bass.

MID BASS: The mid bass section is bigger and thicker but lacks the impact. The mid bass feels loose hence the impact it creates is pretty small. The loose mid bass also lead to that noticeable mid bass bleed hence they sound not that great in terms of separation. The bass does sound good in the simpler tracks but when the tracks get complicated with more background bass drops they struggle in terms of separation.

Despite the usage of the Beryllium coated diaphragm the bass they delivered is of mediocre quality. The beryllium bass usually tends to be more precise with more tightness while the T1s is not that great in terms of above mentioned aspects. The speed is on the slower side thus helps in those nice sub bass rumbles.

Overall the bass is thicker, bigger and bodied while lacking on the technical aspects like the control, separation and impact. The beryllium can be used to reach its full potential but here they have failed as per my testing.



MID RANGE:

The mid range is the more positive aspect in this T1s especially the tonality. Despite that bigger bass presence the tonality felt more balanced and smooth, more pleasing to listen to in simple terms.

The lower mid range has that nice full bodied sound that got carried along from the bigger bass presence. The lower mid section feels fuller and the male vocals have that nice richness. The piano notes and the kick drums have a nice fuller sound but lacks the impact though.

The upper midrange section feels very pleasing to listen to. They are not that accentuated but still able to deliver that soothing sound overall. The harshness is avoided at all costs in the upper mid section hence the guitar strings do sound absolutely fantastic.

The tonality is pretty balanced with smoother edges. The timbre of the instruments felt natural and that's expected from a single dynamic driver. The instrument separation in the mid section felt nice and wide since the staging is pretty big in terms of both the dimensions.

The detail retrieval in the mid section is brought out well and felt above average. The minute background instruments are brought out nicely without any congestion or hindrance. The vocals are placed at an appropriate position which never felt too forward nor very backward.



TREBLE:

The treble section is inoffensive here where they are controlled in all aspects and even in extension. The extension that they possess in the treble section is moderate hence the detail retrieval in the treble section cant be expected that much but the overall presentation felt clean and smoother.

The cymbal crashes, electric guitar strings and the trumpets do sound good but lacks the splash and shimmer. The attack and decay are pretty precise in terms of timing but lack the brightness factor. The bigger mid bass section and the smoother mid section made the treble to sound less brighter hence the instruments in this section got hindered behind the darkness.

The brilliance and the shimmer in the top end is pretty restricted thus the brightness is much reduced with a darker background. The sibilance is kept under control hence no sort of harshness is observed during my testing.



TECHNICALITIES:

STAGING: The staging is pretty big in terms of width and has a good sense of depth since the bass is bigger. The whole presentation felt pretty grandeur without any noticeable constriction. The instruments are nicely placed with a good amount of space in between them thus the presence of air felt nice.

IMAGING AND LAYERING: Imaging is done pretty neat with nice transient response over the channels. The instruments are neatly laid out hence one can easily spot out the instruments without any confusion. The notes at different depths are captured out precisely and the instruments behind them are layered out very well.

The detail retrieval and the separation are above average in this price range. The treble is not that extended hence the details are moderate at best while in the mid section the separation felt neat and clean. The separation in the bass section however felt congested due to that uncontrolled mid bass section.

VERDICT:

T1S, the latest budget offering from the house of Tin HiFi is a well made product with a very good intention of bringing out a nice balanced sounding one. The brand has a well expertise in the audio industry and has their own line of successful products like the T3 Plus etc. When comes to budget offering only few brands are able to catch up the competition since the people’s demands are expensive to meet within a single budget product. The T3 Plus is one of the rare gem which was able to meet the requirements. If you ask about the T1S, does it meet the criteria? Well it's a yes/no situation here.

First of all, the build is great with a nice transparent body and a coloured faceplate. They feel pretty lightweight and comfortable to wear. The QDC connector is a downside though but despite that the connection feels sturdier. The stock cable is fine but could have been better. The stock tips do provide nice isolation and seal.

Second, when coming to the sound aspect they do tick most of the boxes but misses out on some, especially like the bass region. They have mastered the tonality, smoothness and an overall pleasing listen in the budget range via this T1S and a very good upgrade over the T1. The midrange felt lively and engaging while the treble felt smoother yet detailed enough. The worry aspect is the bass where the impact is lacking. Despite the use of beryllium they haven’t unlocked the full potential of it seems. Their bass quantity is bigger and bodied while the control, impact and the separation is pretty mediocre.

The brightness is another factor which is lacking in the T1S due to that bigger bass. The whole presentation is presented in a darker background which is good for bedtime listening but it would have been better if the brightness was there.

Overall the T1S is a very good product with one of the best tonal packages, smoother signature and bigger bass. This is a perfect choice if you already fell in love with products like iBasso IT00 etc. Person who loves the darker background with smoother sound will love the T1S for sure since this is one of the best “TONAL PACKAGE” with smoother sound presentation.

Introduction​

Tin Hifi is well known in the Chi-Fi world and sometimes they come up with a new set for the budget segment. The T1s, which is supposed to be a sort of “successor” of their T1+, were launched at the end of this spring, and in this review we’ll be try to look deeper into what they’re able to offer.

Disclaimer: the sample was won in a giveaway organized by Keephifi. I do not represent them in any way and this is not promotional content.
At the time of the review, the Tin Hifi T1s were sold for $25 on Keephifi’s webstore.

Technical Specifications​

• Configuration → 1DD (Beryllium Coated)
• Sensitivity → 105dB
• Impedance → 32 Ohm
• Frequency Response → 10 Hz – 20000 Hz
• Cable → 1,25m copper cable with 0,78mm PINs
• Connector type → Straight gold plated 3,5mm jack connector

Packaging​

The packaging is very simple, with no fancy paintings or pics. It contains:

• The Tin Hifi T1s
• The cable
• 4 pairs of tips in different sizes

Design and Build Quality​

The T1s are entirely built of plastic, and the samples used for the review has a completely white faceplate.
Since the shells are identical to the ones used for the T1+, and considering that this sample of the T1s shows “Tin Hifi T1 Plus” on one side (see the photo), maybe Tin Hifi decided to make use of the unused shells from the older T1+ production in order to build the newer version.
In general, the T1s are very thin, lightweight and solid, this also thanks to the plastic material which is not uncommon in this price range.

Cable​

The included cable is more than decent for the price, it sports a chin slider and doesn’t feel like the usual cheap cables that are provided with such cheap products.

Comfort and Isolation​

The T1s are remarkably light and their small form factor seems like a real deal from the first look: comfort wise, these earphones are astounding.
Isolation is not the best out there (the thin plastic shells cannot do miracles) but the passive isolation is more than sufficient for daily use.

Sound​

How do these sound?

This is the real reason you’re reading this review (I guess).

[Personal preference: I listen to almost every genre, even though my main preference goes to EDM subgenres. I always like a bit more energy on the bass and on the highs, leading to a personal preference for Y-shaped sound signatures, but if I have to choose, I’d prefer having many different IEMs with various signatures, in order to choose a particular one of them when I want to listen to a specific genre. I love switching between my IEMs so it’s even better if they’re very different from each other.]

TEST GEAR

• DAC: Topping E30
• AMP: Topping L30
• Mobile phones: Poco F2 Pro, Samsung Galaxy S7 Edge
• Dongle: Apple Type-C dongle
• Portable DAPs: Benjie S8/AGPTEK M30B
• Other sources: Presonus AudioBox iONE

Do they need an amp?
No, they don’t need an amp, but when amplified they improve slightly.

Sound signature
The Tin Hifi T1s are L-shaped, with emphasized bass and linear midrange and treble that lead to a pretty warm and dark signature.

Lows: sub-bass and bass are emphasized, and they have decent extension. Bass is very punchy and impactful yet well controlled, perfect for EDM, Hip-Hop and similar genres. It’s pretty trivial, already from the first listen, to hear that its behavior sometimes causes a bleed into the midrange that many won’t like.
Bass texturing is not really great unfortunately and speed is average, so nothing spectacular in this sense.

Mids: the midrange is pushed behind the bass, instruments play in the background, and while female vocals somehow find a way to sound pretty linear and intimate, male vocals are pushed back due to the intrusive and thick bass. Don’t expect serious layering as the T1s are not that great with respect to this.

Highs: super safe with average detail retrieval. They don’t sound closed in, but it’s clear that Tin Hifi wanted to tune these so that treble sensitive people could use them with no issues. Therefore, these sound pretty intimate, and even though there are some hints of air and sparkle, they are not able to provide a sort of “out-of-the-head” experience.

Soundstage is average and while it’s not able to surprise the listener, it is well rounded for the kind of product. Same can be said for the separation, which is more than decent considering that these are dark and bassy at the same time. Imaging, instead, is nothing special, and in this price range there are earphones that do better.
One thing to note is that, due to their signature, the T1s tend to sound much worse with poorly recorded or mastered tracks, so be aware of it.

Some comparisons:
TinHifi T1s vs Moondrop Chu
The T1s are warm, bassy and dark, the Chu are neutral bright with extended treble, hence totally different.
Low end is much more emphasized on the T1s, that also happen to have a less forward midrange and darker treble; the Moondrop Chu, on the other hand, have a more lightweight low-end (which does not bleed into the midrange), leaner mids and more sparkling, airy and detailed treble, while being more fatiguing and more prone to show sibilance.
Imaging, separation and stage are better on the Chu.
The T1s are slightly harder to drive than the Chu.
The Build quality of the Chu is better, but the T1s have detachable cable.
The T1s are more comfortable and they also have better isolation than the Chu.
Summing up, the Chu are technically superior in almost every way, whereas the T1s are much easier to use for long sessions thanks to their warm and non fatiguing signature.

Tin Hifi T1s vs Blon BL-03
The BL-03 are generally airier, more natural and airy, whereas T1s are darker and less “open”.
Low end is boosted on both, but BL-03 have a more natural and ample bass.
BL-03’s midrange is richer, with better layering, more natural instrument reproduction and much better vocals.
The highs are more vivid on the BL-03, that also happen to have more details and sparkle.
Soundstage, imaging and separation are generally better on the BL-03.
The BL-03 are easier to drive and get loud faster than the T1s.
The build quality of the BL-03 is better, but the T1s come with a better cable.
The T1s are more comfortable and lightweight, and they also insulate better from external noises than the BL-03.
It’s a very hard fight for the T1s, but if you search for a comfortable daily driver that can guarantee a non fatiguing sound and awesome comfort, maybe the T1s can have their chance.

Final Thoughts​

The T1s aren’t gonna change the game in their price bracket, nor are they gonna become a sort of new budget standard.
At first, they may seem a non-sense product, and it’s pretty understandable considering that the competition does better in practically every way. But it is when you use them for long sessions that you realize their value and the reason why Tin Hifi decided to cover a market hole that was left open by other brands: a part of the market where the need of a super comfortable, non fatiguing and basshead’s IEM had not yet been met.

The review sample was kindly provided by TinHiFi free of charge in exchange for my honest and subjective evaluation, I only paid import fees and tax.
I haven't received monetary or any other kind of compensation and I don't use affiliate links.
The retail price is $39 but you can grab it as low as $20 during some sale events.
You can order it directly from TinHiFi.



T1S

The T1S is an improved version of the T1 Plus with a re-tuned driver on the basis of T1 PLUS and for the T1S it is equipped with a re-developed acoustic silicon sleeve.
The T1S adopts a new, 10mm beryllium-coated Driver.
While designing it, TinHiFi engineers wanted to find the right combination of weight and stiffness/rigidity, so Beryllium was naturally one of the ideal materials for the driver.
It’s lightweight but also exceptionally rigid as it is 2.5 times lighter than titanium but three times more rigid.
T1S adopts one of the highest strength-to-weight ratios of all materials but with an affordable price thanks to the single sided driver that is 98% Beryllium-coated.



Design and comfort

The T1S has anatomically shaped ear shells that are made from hard plastic.
The faceplate is available in black, pink, white or green while the rest of the shell is transparent so you can actually see the driver and the cables.
Nothing too fancy but at 3.2g each, they are very lightweight to the point that you forget about watering them.
The shells are quite shallow so they fit very comfortably but not too deep and snug, as a result passive noise attenuation is moderate.



Cable

T1S comes with a detachable cable made of silver-plated wires using a 0.78mm recessed 2-pin connector that offers extra protection than usual connectors.
The cable is of good quality, it is not stiff, it doesn't get too tangled, it has low microphonic noise and the 3.5mm plug has an aluminium outer jacket.
Left and right markings are difficult to discern both on the cable and the ear shells.



Accessories

The T1S comes with the detachable cable and six pairs of eartips (three narrow bore and three wide).
A carrying pouch is not included.



Listening impressions

As per usual practice the T1S was burned about 100 hours before listening.
The T1S is ridiculously easy to drive and most of the listening was done with the FiiO KA1, iBasso DC05 and Periodic Audio Rhodium.



The overall sound signature is warm and bassy without too much treble extension, lacking in overall resolution.
Sub-bass extension is pretty good for such a small driver while the rest of the low end is definitely emphasized all the way up to the mids.
Not a bass-head level of emphasis but still good enough to handle electronic music and without masking the mid-range too much.
What gets affected though is the clarity and definition of the bass range itself where the mid-bass gets fogged and overlapped by the lower bass.
This is not necessarily bad as long as you are not interested in critical listening because in the T1S transparency and definition are not its strong points.
On the other hand the bass is mostly controlled and not murky or boomy while it is quite visceral, impactful and dynamic with good timing making the T1S a great earphone for modern music and bassy tunes.
And not only for synthesized ones but also with vocals and real acoustic instruments because eventually the mid-range finds its way to sound present and clear with above average levels of presence and articulation.
It might not be the most detailed presentation but it has some nice warmth and a mostly natural timbre with satisfying harmonic saturation.
The treble is safely tuned, it is smooth and very controlled but not too much as to sound muted.
The T1S is an easy listen, treble sensitive users are going to love it, no brightness or harshness, no sharp overtones but at the expense of detail retrieval, overall resolution and the absence of too much of excitement.
This type of sound signature also has some side effects on the soundstaging properties of the earphone which is nothing too special when it comes to positioning accuracy, instrumental separation or depth layering.
On the plus side the soundstage is quite extended on the horizontal axis and it doesn't sound congested.



In the end

The T1S has a warm and pleasant sound signature with plenty of impactful bass that is not that well defined but it doesn't get murky or out of control.
Easy to drive, super comfortable and discreet is intended to become your everyday partner for casual music listening as long as you don't have excessive demands.

Introduction: TinHiFi is a brand that surely needs no introduction. They rose to prominence a number of years ago for their T2 model, a dual dynamic with a neutral-bright signature that at the time was quite the rarity in the budget segment. They have been steadily churning out models ever since, and unlike Moondrop which basically releases the same IEM over and over again at different price points, Tin opts instead more for the “throw everything at the wall to see what sticks” business model. To be fair to them, this has produced some very nice models such as the T4 and the T2 Plus, but at the same time we have also gotten more disappointing models such as the T5.

In for review today is the T1S, the second iteration on the original T1 model with a slightly altered tuning over the first successor, the T1 Plus. And in fact the shells and some of the packaging amusingly still read “T1 Plus” instead of “T1S.” The differentiator for this product line is that it is beryllium coated, perhaps not the complete marketing coup that this would have been two years ago, but still it’s probably the least expensive IEM out there making this claim.

I would like to thank Zoe at TinHiFi for sending me a sample to review. You can purchase one for yourself here if you are so inclined, currently on sale for $23.



Packaging & Accessories: Packaging and accessories are fairly basic, as is to be expected at this price point. Thankfully the earpieces themselves arrive encased in foam for safe transportation. There is a set of silicon tips which (as usual for Tin offerings) are perfectly serviceable for my ear anatomy, although obviously I can’t guarantee the same will be true for you. I appreciate the fact that they are wide-bore tips since the T1S is an L-shaped monitor. The stock cable is fine, fairly chintzy-feeling but it has a working chin slider and everything. There’s no carry case.



Build & Comfort: The ABS plastic shells are extremely light, and quite small — no issues with side sleeping for me at all. They’re very comfortable but don’t isolate particularly well (and of course they are double vented as is standard for DD implementations). I never experienced any driver flex. Thankfully TinHiFi has switched to QDC-style 2-pin connectors from their prior MMCX implementations which were often a sore spot for the community due to longevity issues. Other than that, there’s not much to say: it’s a $20 earphone, but there are no real issues with build quality here that I can tell.



Signature: As I mentioned before, the T1S is a warm, bassy, L-shaped IEM. They seem to have toned down the bass and lifted the upper mids push a bit as compared to the T1 Plus to give it a little more clarity and balance, and while I never heard the T1 Plus I actually like the tuning here much more than I would have thought if someone had randomly showed me its graph. It’s just a relaxed, warm, inoffensive type of tuning that clearly won’t come anywhere close to satisfying the type of analytical listeners who loved the T2 but will perfectly suit those who just want an inexpensive earphone with which to chill out and listen to some tunes.



Bass: There’s a generous elevation to the low end, focusing on the mid-bass as there is some rolloff in the sub-bass region even though it does retain some decent tactility. It’s not the most nuanced or textured low end I’ve ever heard by any stretch, but nevertheless retains fairly good control given its punchy heft. There’s some bloat here, but again not so much as the graph would predict; maybe the beryllium is even doing something!

Mids: There’s a fair bit of warmth bleeding into the midrange, which helps to give very good note weight and body to male vocals and deeper instrumentals, although it does tend to suffuse the scene so that there’s not much sense of openness. However there is a decent push into the upper mids, providing some much-needed clarity, but stopping short of the point of shoutiness thankfully. Still, it’s clearly tilted towards lovers of male vocals rather than female.

Treble: Surprisingly the treble isn’t totally buried by all of the low end warmth, and there is even a moderate amount of extension and air. Cymbals for example are certainly recessed, but retain a natural sound and even a bit of sparkle. It isn’t an exceptionally even treble response, but neither is it anywhere close to peaky enough to be offensive in any sense.



Soundstage & Technicalities: The T1S isn’t going to win any awards for $20 IEMs on the technicalities front, but even so I was surprised at its relative competence given the tonality with which it is working. The soundstage is on the smaller side, but is actually fairly proportional in terms of width and height. Likewise, there’s not a lot of instrument separation given all that warmth, but it does manage to accomplish some degree of layering and even on busier tracks keeps the congestion somewhat in check. Resolution and detail retrieval are muted due to the tonality, but there’s not obliterated either. Timbre on the other hand is pretty good. All in all, I would say technically they are “good enough” given the signature and price point.

Conclusion: Between classics like the BLON BL-03 and heavy-hitting newcomers like the Moondrop Chu, the $20 price point is no cakewalk these days; even beryllium coating is not enough to guarantee the sale. But at like any price point, the real question is: what kind of IEM are you looking for? If you want a more relaxed and laid-back BL-03 without the issues with fitment, and you like punchy mid-bass and thick lower mids, you might be quite happy with the Tin T1S. Likewise, it might work really well as a gift for a casual music listener who would normally buy Beats. And I mean, even though my normal preferred signature is much different than what the T1S provides and I’ve been going back and forth between it and a $650 IEM, I still find it very enjoyable for what it is — especially at the end of a long day when I just want to sit back and relax. For $23, it may not do anything particularly well but neither does it do anything particularly wrong.

The Tin Hifi T1s have been sent to me by Linsoul in exchange for the publication of this review. They have not made any specific requests but I will leave a (non-affiliate) link to the T1S via their webstore on my blog, as usual in these cases.

I will do my best to be as sincere and unbiased as possible in this review but it is always worth considering the fact that these IEMs have not cost me anything.



Intro…

I have owned a few Tin Hifi IEMs over the years, with the T2 being one of my first sets back when I started in the realms of IEMs, something that seems like a long long time ago, seeing how many models have been and gone since then.

I have also reviewed a couple of Tin IEMs on Acho Reviews, one of which were the Tin T1 Plus, back in 2020. This set is the T1S and I believe they are an an updated version of the the Plus, although I have done my best to not really know anything about them (as usual, when possible).

I do know that they use a Beryllium plated dynamic driver (according to the spec) and that they come in at less than 20€, placing them firmly inside the sub 50€ category I like to point out.



Presentation…

I got a little smile when opening the T1S as it is basically the same presentation as the T1 Plus, in fact, when sliding the box out from the cardboard sleeve that shows the model and the spec of the T1S, the box actually says T1 Plus on it.

Basically it is a no frills presentation, containing the usual IEMs, cable, a few sets of silicone tips and the warranty card. Nothing special but nothing to complain about at the price.

Actually, after recording the video for this review, while taking photos, I noticed that it is not only the box that has T1 Plus on it, the shells of the IEMs also say T1 Plus on them. So I guess that they are using up what they have in stock left over from the T1 Plus. I have no idea if at some point the T1S will start to have its own name on the shells, I suppose it depends on how much stock they have left and how many T1S are sold.



Build & Aesthetics…

The T1S are available in 4 colours. In my case I received the black which is the only set that features a semi transparent faceplate, with small silver speckles on them. They are completely made of plastic and are (obviously!) the same size and shape as the previous T1+.

This means that they are very comfortable and also very lightweight. They are amongst the lightest sets of IEMs that I have (as are the T1S). There is no discomfort or fatigue from them over long periods, due to the ergonomics (which fit me well, but obviously everyone is different) and the lightness.

The cable is also quite thin and light, and although it does get prone to a little tangling, is not terrible. Nothings special but again, nothing to complain about at the price, it gets the job done. They have also stuck with the use of 2 Pin connectors, something that I personally appreciate.



Sound…

Before commenting on sound, let's take a quick look at the graph comparing the T1+ to the new T1S:


(all measurements are available on achoreviews.squig.link)
You can see that there isn’t a lot of change between the tuning of the two, however, I will say that the small tweaks have been for the better. Now, it is not a night and day difference between the two, but I do find the newer T1S to just be more cohesive overall.

Starting off with sub bass, there is a roll off as we get down into the lowest notes, with even less presence than on the previous set, however, it still gives enough rumble for things to be pleasant enough in the bottom frequency range.

I don’t think these are going to be the pick of those that want a huge rumbling low end, but the boost of the midbass is enough to give the impression of them having quite a presence down low. This gives a warmth and smoothness to electric bass guitars and other instruments sharing the same sonic space, and while it is a little too much for my personal preference, it is by no means offensive nor overpowering.

The midbass boost does roll over into the mids and while it may seem like there is some bleed on the lower end of the mids, it doesn’t really sound too bad, it gives a nice warmth to the lower ranges of vocals, adding a bit of smoothness to male and female vocals.

There is a dip as we get to the middle of the mid section, although it is less pronounced than on the T1+, with the climb towards 3kHz starting a little earlier than on the previous version. This actually makes them sound less V shaped in my opinion (although it is still really a V shaped tuning overall), giving them a little more clarity in the upper ranges of vocals and presence of the notes found in the higher mids.

As we climb into the hr ranges, there isn’t much extension up there, I don’t think anyone is going to consider these “airy” or “extended”. The upper treble does remind me of the typical upper treble found on so many budget IEMs with single dynamic drivers.

The soundstage is pretty much average for a set of IEMs, with nothing spectacular going on. Images are easily located but they are not pinpoint images, more of a general placement that works for things like binaural and panned stereo images, without any real placement of background details.

Speaking of details, they are also nothing extraordinary, although I do feel that they are a step up from the T1+ in this regard. There is nothing that is going to jump out and make you say “wow, I didn’t know that existed”, but at the same time, they don’t make you feel like your music is missing anything.



Conclusion…

I feel that the T1S are more similar to the T1+ than not. There have been some tweaks and these are for the better, in general they are a better set of IEMs, although I don’t think there is anything amazing about them.

When I reviewed the T1+, I said they were more focused on the casual listener than anyone looking to focus on details, and I feel that the T1S are in the same category. They are a set of IEMs with a fairly safe tuning, with a pleasant overall sound that shouldn’t really offend anyone. I can’t see them polarizing opinions.

They are very comfortable (for me) and very lightweight, so if you are looking for a budget set of easy listening IEMs for daily use, then I think you can do a lot worse than the T2S, there is no doubt that they are worth their price tag.

Prologue​

Tin Hifi is no stranger to anyone. Focused mainly around the budget segments, Tin has paved its own way into everyone’s eyes. With two main line-ups, the T and P series, there’s an offer for everyone.

P series are the planar segment, which we will not talk about today, and of whose I’ve only heard the P1 Plus (while I keep my eyes on P1 Max), but we are going to rather talk about the T series, that have a DD as a core, either it’s alone or accompanied by something else.

Just like the planar craze that the P series are trying to keep their blood on, they are also focused on another market war: the ultra budget segment. Kicking in at 20 USD, T1S is the latest offer of Tin Hifi, with a single DD under its hood, claiming to have a beryllium coating on it. For those who don’t know, beryllium was very much appreciate once it got more common and accessible to the wallets, so this got my curiosity to say the least - I’m still a firm believer that a better tuning and/or implementation go a longer way, but it’s great to see this kind of stuff around this lunch money price, at least to some.

Given the influx of ultra budget IEMs lately, it’s not hard to imagine the competition will be rough, so let’s dive right into it.

Non-sound characteristics and accessories​

I know it will come as no surprise, but the package, accessories and build quality are on the budget side of the budget segment. What do I mean by that?

The shell is very small and thin, made of plastic and it gives it one of the cheapest feelings I’ve ever experienced on hand. Despite me feeling I could easily break it with my hands if I throw it around, this doesn’t bother me much as it’s light as a feather and has a rather easy fit to my ears, which I feel someone who has fit problems with bigger IEMs would appreciate.

As far as accessories go, once again, it goes as expected for the price: cable is not the worst I’ve seen but it’s very thin, tangle easy and hardware is made of plastic - comes in 3.5mm only. Regarding tips, the ones included are very wide and short, which I actually think work with this IEM, but I’m sure they won’t fit everybody - be ready to tip roll on this one, - while the biggest size almost doesn’t seal on me.

Sound characteristics​

Tuning

We are in May and for those who live in south Europe at the moment, the weather will match this Tin pair, as they are extremely warm.

The sub-bass is a bit rolled off and is noticeable when compared to the mid-bass (Hans Zimmer - Dream of Arrakis) - it for sure could use some more extension and rumble. I would say it is on the average side of tight (Kendrick Lamar - Backstreet Freestyle), tilting towards the slower side of the speed metrics (Polyphia - 40oz).

This is actually a double down for my preferences as mid-bass is too elevated, and let me explain to you why with some examples. When listening to *Throw Away Your Television’*s intro, Flea’s bass is way too forward and blurred. This causes mainly two problems. First problem is that all this elevation and shelf shape affects the bass directly, giving it a sense of lacking detail and texture and also not feeling too micro-dynamic as expected - kickdrums aren’t thunderous as you would imaging from the graph (Ghost-Note - Shrill Tones).

The second one is that the mids are overly affected by its bass bleed, which causes the usual lack of transparency I look for. A great example of this would be pianos that get mushed into the rest of the song, sounding too thick and lacking some detail (Hania Rania - Glass or Nils Frahm - Says).

As for vocals, the male ones (Michael Bublé - Feeling Good) feel a bit husky while the female ones (Adele - Daydreamer) lack a bit of bite, sound nasally in some tracks, but never shouty which, lesser evil to be honest.

To me the treble is the best tuned region of this set. It’s not perfect, but it’s slightly different than what we get used to in this price range: no overcooked peaks attempting to give false micro details, no fatigue whatsoever and on the dark side, which I usually prefer (Iggy Pop - Lust for Life). It has some extension but its mid treble is clearly on the darker side.

Technicalities

As expected for 20 USD, the technicalities are mostly sub-par. Stage is rather small without much depth or height, imaging is not great and the detail level is low (Agnes Obel - Curse).
Timbre is very good for its price point, and I would say it’s one of the T1S strongest points in this department.
Separation and layering aren’t the best, but if you factor in the stage size and warmth, it’s not too shabby.
While listening to Polyphia - Playing God I got some sense of macro dynamics, which is again good for the price range, but the notes where a bit mushed up together and lacked definition between strings.

Again, this is what it’s expected for a 20 dollar IEM, but the market has become a minefield around this segment, so the competition is tougher than ever.

Comparisons​

• CCA CRA (with Final E tips)

Where the T1S can sometimes feel small and congested, CRA feels airier but also thinner - this is pretty evident to me on female vocals, where the presentation is good due to this sense of “air”, but the vocal replay feels more natural on the T1S. The CCA monitor shows a more “wispy” presentation, that also comes as more detailed, while the T1S is more softened out and organic.

The trend follows as we move up to the treble region. The darker replay of the T1S gives it once again a safer reproduction - fatigue and overcooked free. The extension is more present on the CRA where I can see it shine more on more treble demanding libraries. To me, I would take the T1S treble if I had to choose one.

Doing a full reverse to the start line, the bass is also pretty different between the two. CRA focus on the lower regions where T1S focus on the mid frequencies, at an arguable cost of mid clarity. Regarding intangible characteristics of the bass, CRA is the clear winner thanks to its speed, impact texture and tightness, making it better suited for more technically demanding bass libraries - double kick drums or guitars comes to mind.

Regarding technicalities, T1S is better suited in the timbre tests with my library, where the CRA shows a better capability of producing a better picture of the stage. Thanks to the tuning, T1S does also come out as less resolving overall.

• CCA CRA+ (with BGVP W01 tips)

Just like its older brother and if you read the above comparison, the CRA+ will have basically the same turnout when battling Tin’s IEM. The reason I decided to include the CRA+ it’s due to the tuning, making it a more fair fight.

If a couple days ago I just mentioned that CRA+ has too much mid-bass to me, T1S takes it a step further. Again, this has direct implications in the mid-range and the overall perception of the psychoacoustics throughout the spectrum.

Basically, everything I said about the CCA CRA above still applies, with some subtle nuances. Treble disparity on CRA+ is better tuned than its predecessor, making it closer to T1S, but it still has some nasty peaks, which also affect the timbre.

Technically, I think the CRA+ is closer to the T1S as well, due to the tuning.

• Moondrop Chu (with Final E tips)

The time has come for the current 20 dollar king to show up. Starting right out of the bat, their presentation comes out as polar opposites. The Chu feels cleaner, transparent but also arguably less natural.

The tuning is undeniably more balanced in the Moondrop’s, and also appeals more to my ear, but I can see the lower treble to be on the T1S side of the court - and this is also followed by having a better female vocal body to it, a more organic replay. Where Chu might get close to sibilant when volume is raised, T1S holds up. Once we go past this area, Chu wins hands down, especially in the most upper regions.

Now to the overall presentation of the sound and technicalities, Chu offers a better depth to the sound while feeling less congested with better separation/layering, especially in the mid range. This area is where Chu shines and where T1S falls short, pushed by its bass tuning.

---

Bonus track​

While doing this assessment, I tried to tune down T1S bass by adding some PEQ to the mix. The result was fairly impressive to my ears and I decided to graph it.

I usually avoid any type of modding or eqing in my reviews, but we are talking about a budget segment and these might shine some light on some potential buyers/current owners.

PEQ settings:
Peak @ 20hz, +6db Q:1
Peak @ 100hz, -2db Q:1
Peak @ 150hz, -1db Q:1
Peak @ 250hz, -3db Q:1
Peak @ 400hz, -1.5db Q:1.5

Click to expand...

The point of this change is to open up the mids and free up the presentation, leaving it more analytical while still being very musical.

---

Conclusions​

As you might have guessed, the T1S isn’t for me, but it might be for you if you are a warm-head. I really think that offers like the CRA+, which compete directly with the T1S’ tuning, are way more valuable for just 8 dollars more. Again, to me the Chu is still the king of the lower bracket and I would pick it over, for the same price.

I think Tin tried to get their own slice of the cake that everyone now wants, but the timing wasn’t the best. This court now belongs to solid offers and competition has to bring the A game to challenge them - and let’s take a moment, as consumers, to appreciate this!

Despite the competition, the driver on the T1S doesn’t feel that good, despite their achievement of making an ultra budget offer that doesn’t give me headaches after testing it for some days now. I hope Tin goes back to the drawing board and comes out with new and spicy ideas, with better build quality and accessories as well.

Value stars: 3.5/5. Personal ranking: 3.5/10​

All my notes were taken using Xduoo XD-05 Plus with Burson V5i Opamps and using BGVP W01 as tips. Other sources were used to listen to this IEM like the Cayin RU-6 and Hiby R5 Gen2, but the final sitdown was done with the XD-05.

Thanks for reading!

Welcome to Head-Fi!

This beginners headphone offers a thick and enchanting sound. Amazingly the TINHIFI T1S In-Ear-Monitor produces an even, correct and complete frequency response…………….it’s a great way to get started in this hobby. While sold for only $20, it’s built well, and offers superior fit and comfort.

It happened again!
I found another Golden Retriever. I’m not talking about dogs silly! I’m taking about headphones. This is a headphone place.



No, I’m not referring to finding a lost dog.
There are basically three different styles of IEM playback.

1) One is finicky. It’s a high maintenance IEM. Nothing is really wrong with it, as long as you pay for expensive dinners and shoes. If you get it high quality playback songs, and/or sources you're in. The playback will actually serve you well. But give it the wrong amp and things simply won’t work out right. You’ll be sorry! These types may be better off with someone else, still the time you spend with them can be genuine and pleasurable. They simply take care in feeding!


2) The next is Bad. Yep. Simply an uneven, incorrect and maybe incomplete playback. There is no way to get correction to the sound. There maybe brief moments of success, but the window of opportunity for such playback is small, even smaller that #1.............to the point that it’s really nonexistent. Such is life, as nothing is perfect. Though if you look there are examples of better IEM playback. What we don’t have here is forgiveness, combined with a loss consistent playback character. We are not even talking subjectivity here! These are IEMs that get bad reviews, and anyone who gives them high marks is inexperienced, a paid operative, or someone looking for something free!


3) The third and final category is The Golden Retriever. This style of IEM can actually be at any price point. Sometimes they cost a lot, sometimes they cost a little. It’s not always about money but of course at times it is. Still, what we are looking for is beyond monetary value. It is simply the result of effort on the part of the manufacture. But more than that it is an example of experience, the experience the manufacture has at making something good. Just like any business they learn from trial and error..............what to do and what not to do. Often a manufacture obtains economy-of-scale which allows them to include parts and technology that typically the others guys just can't offer. Such concepts are truly found in the TINHIFI T1S. They have used the years of experience to mass produce this T1S IEM. The aspects I will talk about are simple really. The great design and build of the cable, the IEM comfort and fit, and of course the quality of sound they were able to milk-out of this single 10mm Beryllium alloy diaphragm!

This is science, but at times also a crapshoot. Meaning even though there are ample resources available, there is still an element of luck involved.

The reason for the Golden Retriever name is just that, just like the dog..........some IEMs get along with everything and everybody. The best IEMs simply play all musical genres well and offer an easy going nature. They also play well from most sources, be it a phone, a DAP or a desktop! They just get along harmoniously as their role in life, and as result become something of value.

Because this game is a science and an art it's actually unpredictable. If this was simple then everyone would make a good IEM and you could buy it already knowing the quality. Of course there is always that aspect of subjectivity. What takes place is some IEMs appeal to a certain style of listener or someone who specifically listens to a certain style of music. And of course all that is true. Still there is a way to make great IEMs that appeal to a wide range of listeners. Believe it or not when I started in this hobby I didn't even know each IEM/headphone sounded that different. When I needed a headphone, I just went out and purchased one. Only later I found out that there was a range of "personalities" which needed to be taken into account. But the Golden Retriever IEMs/headphones truly exist and allow the choice of buying to be a lot simpler. You would expect the larger manufactures would gravitate towards a generically good IEM. Also let me point out generically good doesn't mean generic sounding. In fact, that's the point of this whole review, that just because this is a low cost IEM doesn't mean it's boring. The success here is the result of the T1S tone reproduction appealing to the masses combined with excitement. Combine that with comfort, well-done construction, and nice accessories.............TINHIFI can't lose!

TINHIFI can't lose....at least with this one!



Artificial Music Reproduction:
It’s an artificial means of music reproduction.........lol it's always artificial! Yet, the build process and ingredients can be quantified and registered. But there are still the intangibles........mystery intangibles.........things that aren't even named.

Basically you have frequency response and technicalities. So the technicalities are every thing other than frequency response. These things are decay, reverb, instrument tone ability, timbre, transient response, etc etc. What does all the FR and technicalities boil down to? Musicality!

Musicality! Simple really. Artificial Music Reproduction.

Disclamer:
I was given a prototype model/package which displays implementation of the new T1S 10mm Beryllium driver/re-developed acoustic silicon sleeve. The shell of the IEM still said "Plus" as well as the packaging had both T1S writing and Plus designations.

The cable: What? Are you serious?
The cable actually made my day! I mean......I have done a lot of IEM/headphone reviews and done countless unboxing of IEMs, but this truly was a heartwarming experience. And I didn't notice what I had at the beginning? It simply looks like a regular black cable......lol. Upon closer inspection the plug cylinder is manufactured out of aluminum. Next they scored an edge into the cylinder to make something for you to grip onto when using the cable. The plug is gold-plated as well as the cylinder is painted with this really amazing black enamel. The next thing I noted was the matching strain-relief, then the fact that the chin-slider made from a nice black bead. The other thing was the coating material and braid of this cable; the cable lays correct and is always manageable. The cable is never fussy or goes out of control. It coils correctly and sounds fantastic. I will probably describe the cable again in this review, deal with it. Truthfully I can't get over it. This is what you get when you invest in a big name brand.





The build/design
A simple two piece clamshell construction, with cable mount. The resin build is robust and shows a glitter face-plate. The qdc style of connectors enable a secure placement of cable mount. I will go into the connectors again later in this review. Probably the biggest thing you take away from the build is how they are incredibly small and comfortable. They also have two air vents on the inside. This is the quintessential beginners set, as they have giant R and L markers on the shell as well as huge R and L markers on the cable tips! There is a metallic sheen to the screen and a nice nozzle lip with goes to hold the tips on fine. This is a two piece shell design with qdc cable risers. Comfort comes from nozzle length as well and the angle it sits at. Brilliant ideas and marvelous execution.........a 10/10 on all perimeters.





The sound:

Treble:
You’ve heard this style of sound before.....maybe, though I’m not sure at this exact price-bracket? While price-range does delineate the level of top-treble involvement.......it’s ignorable due to the nice rolled off. They have done it well.

I’ll be darned, I have all I need. There is no boring lack of detail like first noted upon taking it out-of-the-box. Newly out-of-the-box the sound response was truly missing something? I was dreading this review. So you can only imagine my surprise at what happened after 24 hours of burn-in. Somehow burn-in did the trick?

The treble is supported by the upper midrange, in such a way that they seamlessly blend.

I tried all kinds of music, only to find the treble never boring or inept. In fact I would call it "My cup of tea!"

Trying the ultimate test of fast progressive metal, it started to show the holes in its facade. Where at times (of course) there are tiny intricately spread-out reaches of detail. But at the asking price, that’s totally forgivable....and nothing here is off or wrong. It just doesn’t have that super-top treble complexity that more expensive IEMs offer. Though the reasoning here is FR done right is actually cheap!

Meaning it cost absolutely nothing to offer a correct tune!

And FR is 80% of why someone really likes an IEM. So....they have FR down. You will be surprised at the the speedy-bass surges that occur with songs you know! I will save that for the bass section, but I can’t help be distracted! Totally distracted!

I became distracted by the music playback.

So the question is..........do we start to miss the left-out treble attributes? I have listened for two days and that’s definitely a no. I mean there are passages where the instruments get slightly crowded, and truth to be said...........these do better with slower-music, but still they are great. It’s the soundstage that first hits you. That and they are working with that soundstage and filling it out. Nice tiny embellishments make it out to the edges. At the same time stuff is relatively fast. Not super fast but fast enough to be a solid thrill. And to think about the youngsters who will buy these that have never been exposed to anything better! Lots of smiles to be had!

The Midrange:
First off, I just want to mention that this is where I got my start in Head-fi. In 2006 I started my IEM journey. Before 2006 I was only a full-size aficionado. But slowly I found IEMs that I liked. In 2016 I reviewed a number of $20 IEMs. And to think how far we have come! The fact that $20 buys a lot more musicality. Here the midrange is where it all goes down. While it’s not the the most detailed, it does have a totally correct tone. Meaning they have this FR thing down now to a science. Not too bright, not dull or boring, but the midrange is right where it’s supposed to be. Big too.................spread out the pretty far. It's really the soundstage that has you guess that they would be more expensive IEMs. Truly the soundstage has no business being this big at this price point!


The mids have a lot of responsibility too. Meaning they can be tuned an assortment of ways. Probably the mids are the most crucial to an IEMs tune. Meaning I can deal with a lot or a little bass. I can deal with somewhat of a bright treble, as way up there there is not all that much energy. But if the mids are wrong (and there is all kinds of ways of doing them wrong)..........then trouble takes place. The midrange in the pinna gain area is mankind's most sensitive area. There can be almost dBs of variance where it's either loved or hated. Don't know if you have noted but the interpretation of the midrange ends up being the area where IEMs are either liked or disliked the most. This area either makes an IEM workout or become a failure.

Here though......the transition from lower midrange into the regular mids is where it's thick and meaty. Though the most TINHIFI T1S action really takes place in the lower midrange and midrange.

This is really a lower midrange and midrange soundstage.

Sounds like guitar are nice and full, but obviously the vocals really take all the spotlight. Here the vocals are just right. Still it’s the DD reverberations that make the midrange special. Combine the reverb we naturally get from a DD and combine that with good vocals and that's what we have. They haven’t held anything back.......somehow integrating reverb/decay into the vocal and midrange playback.

Anyone can charge a lot for a high-end IEM that does timbre and instrument tone well. But here, the great part is they are doing it for $20.

Though I will mention that I’m using my more midcentric DAP. The Sony WM1A with MrWalkman software. With the desktop and WM1Z it was a hair too bass heavy. Still the TINHIFI T1S is so forgiving of sources, you will also be fine simply using a phone. Still they do like power and will upscale with your better gear!

Bass:
I don’t know when my affinity for bass started? It wasn’t always this way. But sadly I almost completely judge an IEM on bass performance. That means if there isn’t a well done bass, the IEM has very little value. I am not talking about quantity, I'm speaking about good bass timbre and texture. But also it’s more about a full-sound.

Emersion is what I need.

Without emersion I may as well be listening to a table top radio. This emersion is here. It’s a lot more than the price of admission. It’s simply great. That’s the only word I have............great. That and it’s well rounded. Well rounded because you can play a wide variety of music and get exactly the same response. That said many of you are reading this and still thinking the total sound quality due to the price bracket. It's "OK" as you can be forgiven for thinking in such terms. But if I was to make one statement in this review, it would be that this is not a foggy low end. The fact that the value here is they have sculpted a really well done low end. Such a thing adds to how you are able to perceive the mids. Nothing is fighting for noticeability, though it still is thick and it is emotional.




The Completeness:
Normally common sense says this entry price bracket would have you wanting something. Though you may not realize that most people think $20 IS the correct price to pay for IEMs. That means for the amount they sell for.......the profit is from the number of units sold. Literally this IS the price bracket most people pay for IEMs.

We always forget we are a very small percentage of the consumer market.

So what’s left out? There has to be something, right? Interesting enough there really is not that much more to want. Obviously the soundstage is better the higher you go up the food-chain. But really let’s start with soundstage, because it’s maybe the main thing they really pulled-off. It’s relatively expansive and nice. Really you would have to hear it to fully comprehend what’s up. The Frequency Response is good and really complete. With-in the FR we can hear fully the vocal detail..............the vocals actually don’t sound set back at all. There is a full-level of bass impact that doesn’t go overboard to overlap on the midrange. What’s especially cool is when you can hear multiple instruments all playing at the same time. The fact is the only true things we don’t have is a slight, ever so slight high extension, as well as there is a very small area where you realize that tiny level of bass could be better with TOTL IEMs. Probably that is part of what you sacrifice using a single DD for everything. Though what is missing up-top and at the bottom.........it more than makes up with cohesiveness and soundstage!

They used the latest technology to add special Beryllium alloy 10mm diaphragm to create this style of response. Such a diaphragm is 2.5 times lighter than titanium, 3 times more ridged than titanium..........this simply results in a more responsive playback. And you can hear it, you can fully hear how the sound is more dynamic, faster and more complete than prior ways of building budget IEMs.

The TINHIFI T1S doesn’t look like much, but then when you place it in your ears..................it’s startling! It really is.


It’s built well, and all the extras included are nice, but it simply looks like a $20 IEM. Though sound is a whole different story. I used the included cable for 100% of my testing. The cable has a style of qdc plugs which allow the cable to cover an area of the 2 pin, which extends out from the actual IEM body. Such a design may end up stronger allowing an extra level of protection from side to side plug dismantling forces? Also it only allows so much downward force placed on the two pin connections. As far as 2 pin placement....................it takes a little effort simply to get the plugs in-line with the actual IEM protruding qdc cable risers. But once you find the correct angle, all is well. The cable is silver plated joined with 0.78mm 2 pins.

The entire IEM weighs in at 3.2 grams which makes wearability a breeze. There is also gentle ear-hooks which come into play to both guide the cable over the top of your ears as well as keep the cable in looped shape. The only thing that I didn’t use were the tips as I just happened to have a pair that I like. But I did try the tips and found them more than adequate! The main benefit of a small and lightweight IEM is they pretty much always fit good..............you can also choose the T1S to sleep with if so inclined. This style of design has the transducer laying very close to your ear which also helps block out outside noise.

Conclusion:
TINHIFI truly outdid themselves with the T1S. It comes in at a whole $5.00 to $9.00 less money than the previous "Plus" model and does the music part fantastically. If your looking for a sports IEM, or just need an extra pair for out of the house, the TINHIFI has you covered. They come in four colors, have a great cable and a quality build. They come with a nice, nicer than expected box-opening experience. While not the end-all, end-all in detail, they have the Full Frequency Response that is fulfilling and pleasant. They are gifted with a full-range 10mm Beryllium alloy driver that produces an even, complete and correct rendition of your favorite tunes. The IEMs themselves stay comfortably in place and look fantastic, they are made well and do the job they were designed to do. You may surprise yourself and make them your main IEMs! I was pleasantly surprised in the process of writing this review. What I thought was to be a low cost boring IEM, turned out to be miles better than I ever could have guessed!
