Pros: Good tonal balance and timbre, neutralish tuning, great built design, comfy, decent price value
Cons: Poor clarity-definition, average technicalities...
Overdue Tinhifi T2+ mini-review:

VALUE: 8/10

The plus:
balanced, natural tonality-timbre, nice vocal, smooth and inoffensive, safe tuning, rather wide-tall soundstage, mature all arounder, good macro-resolution

The So-SO: Average micro-resolution, average technicalities, lack of air and sparkle, poor imaging, strange bass to mids transition, lack of dynamism and bite in attack, a bit muddy layering, upper treble roll-off, niche tonality that will be hate or love affair in term of musical enjoyment, warm sloppy-ish unrealistic bass, soundstage have no deepness and sound is opaque.

Since the beginning i just can't fully enjoy the sound flavor of T2+, even if i try all ear tips possible, different source and amps as well as doing some mods to improve clarity of imaging and attck heft...if you were a fan of T2 lively textured sound, the Plus is NOT for you, if your a fan of something like Final E3000 or E4000, the T2+ might be an interesting side grade.


Flat, warmish and thick sounding is the T2+, the tonality is cohesive like melted sugar in caramel...everything is closely stuck together and bass tends to mix with rest of the response even if it isnt boosted.

Soundstage is above average in wideness with right ear tips but lacks deepness and tallness.

Imaging is rather hollow in clarity, so no precise instrument spotting possible, it does have a good amount of sound layers info but lacks silence and space to be articulated properly.

The bass lack texture, separation, well-defined attack and extension. It sounds like a bit muffled and you will struggle to guess what exact notes is played by a bassist cause tonality is too warmed. Midbass has good weight and thickness giving pleasant slam, not a fast thigh one but slow and not particulaly well separated from mids.

The Mids are the best part of T2+, very natural in tonality and timbre, tough not very textured and kinda dark in resolution. Both male female vocal sound alright, its not too intimate and have an open wide presentation but separation lack air and layers feel stuck together closely even if mids are on the top of the thick cake. No sibilance to be found. Smooth, pleasant, a hint organic. Transparency is just enough, which permit wide enveloping presentation.

The Treble is a mixed bag here, from low to mids treble it's near-perfect: full, natural, rich and never splashy, sibilant or harsh....but their NO air to be found, neither attack bite or sparkle which will be underwhelming for guitar lover-electric or acoustic. As well, texture and micro details are hard to find. The top is roll off and relaxed, percussions are sometimes far in the back and some details get lost behind prominent mids. Lean until it drop, not very energic, will sue bore to death the treble head hungry for attack snap and details retrieval. Lazy tonality not for lazy ears.


VS Tinhifi T2:
T2 is brighter, punchier, more lively, more W shape and energic. Soundstage is bigger-deeper. Bass have more mid bass boost but it roll of faster so less rumble length, still, separation is better and attack is tighter, we have more texture too and faster weightier attack. Mids are brighter, more detailed, have better separation and definition and more upper mids presence so less smooth-organic. Treble is more detailed and crunchy, it has more bite but not a lot of sparkle even if a bit more than T2+. Everything sounds faster and thighter with the T2, but not as balanced and lean as the Plus, treble has some tricks to add air, which can subdued highs fullness so while percussion are better to extract it isnt as natural and well rounded as T2+. Yep, the tonality of T2+ is more natural but in an ''impressionist'' way, T2 is expressionist in its musicality for the better and the worst. It take risk while the Plus is too shy and polite.


All in all, the Tinhifi T2+ is a refreshing attempt in chifi tuning, mature yet a bit underwhelming in both technicalities and musicality, the tonality is inoffensive and laid back and permissive so I think its a safe all-arounder. Perfect for a long listening session that will not distract you with spectacular music presentation, not suggested neither for bass or treble lover...more for mid-centric and dark-neutral IEM fans.

A sense of déjà vu ensues as Tin HiFi delivers the definitive update to their classic T2. Read on to see if the brand new T2 Plus has the makings of a new classic.

Not since the days of Tintin, Rin Tin Tin or the Tin Man from Wizard of Oz have there been so much hoo-ha and hubbub over, well, tin. Tin HiFi is revered, and deservedly so, for making great inroads to the budget IEM arena, producing winners while maintaining their signature sound. This isn’t my first rodeo with them either, they left me dead chuffed with their planar offering P1.

With me now is the T2 Plus, the latest in the long line of… wait a minute, wasn’t their last IEM in the T-series the much-loved T4? Why the step backwards, the throwback Thursday? Well, Tin HiFi isn’t a company that takes things for granted, and likes to tinker and retool even their classic products until a definitive version is reached. They’re tinker tailor soldier spies.

This wall of text is guaranteed to ward off Gen-Zers, and fast.
This wall of text is guaranteed to ward off Gen-Zers, and fast.

Besides, wasn’t Terminator 2 (another T2) the greatest sequel ever? Look at how many versions of it were released, so it’s fair game for Tin HiFi, lol. The evergreen T2 was facelifted to the T2 Pro, and now the T2 Plus, featuring a new shell, new driver, and a refined tuning with trickle-down technology from the higher-end T4 and P1. In their words, T2 Plus is the “final iteration” of T2, or the Skynet Edition Blu-Ray, if you will.

The T2 Plus is available in matte silver housing, and is marginally costlier than the original, although well within the budget bracket/racket. You can purchase them via Linsoul or Amazon. I’d like to extend my sincere thanks to Linsoul for the review sample.

Packaging and Accessories
The T2 Plus packaging eschews jet black blandness and the anime girl bandwagon, by sticking to the tried-and-tested T-series formula. The ubiquitous rectangular white cardboard box is here, along with brand and model logos as with other T-series IEMs. Inside, a thicker navy and gold cardboard box is seen, with the proud Tin HiFi logo emblazoned at the center.

The varied inventory of Tin
The varied inventory of Tin “the Toolman” Taylor.

This regal eagle color scheme never gets old, frankly, and conveys a playful elegance. Kind of like me. Open up the lid, and say hello to the T2 Plus earpieces sitting comfily in their foam inserts. Beneath them, packed in resealable plastic bags, are the rest of the accessories.
  • 6 pairs of silicone ear tips in various sizes (S/M/L)
  • A pair of medium-sized foam ear tips
  • A cable
  • Manual and warranty information
What’s painfully missing, besides a waifu, is a carrying case for your T2 Plus. Not even a cloth pouch was provided, which leaves you with little choice but to source for a third-party case, or carry the whole box around comically. I approve of the latter by the way.

Much thought was put towards the cable, and it’s not just for show. The cable is made of 4 wires of 22AWG silver-plated copper, reinforced with Kevlar to reduce microphonics and improve durability. Adorning each end of the cable are gold-plated MMCX connectors and a 3.5mm jack. The cable handles superbly with top-notch ergonomics, being soft, supple, and flexible. I was satisfied enough to conduct the entire review with just the stock cable.

Design and Build Quality
Moms around the world preach and teach that it’s what’s inside that counts, and T2 Plus can’t wait to show us its beautiful internals. Scaled down from its previous iterations, the driver is a single 10mm DD made from NanoPure nickel-zinc alloy. It’s better to have a single, high-quality driver rather than stuff a few together to see what sticks. Big brother T4 follows this philosophy too.

Protecting the drivers are brand new, CNC-machined aluminum alloy housings, offering arguably the biggest change from the original T2. The Plus looks absolutely dapper in matte silver, while the rounded finish provides a sleek and handsome profile. The housings look way more luxurious than they have any right to, and it seems the outside matters just as much as the inside in T2 Plus’ case.

Whose line is it anyway?
Whose line is it anyway?

The housings are fantastically built. The outer shells are so smooth and congruent that you barely feel the vents or the crease separating the two halves, almost like liquid metal. But unlike T-1000, the shells are robust and solid and can take a knock or two. I’ve dropped them a few times during the course of review and they escape unscathed. Don’t hate me.

Fit, Comfort and Isolation
When something looks and feels as good as the T2 Plus, I can only follow my primal instincts and shove them straight into my ears, like plunging headfirst into a new, ill-advised romance. Its silky-smooth surface begs to be cuddled and caressed, and putting the T2 Plus in, they sit flush in my ears. The nozzles are just the right length, anchoring the earpieces with moderate insertion depth.

And the comfort, oh the supreme comfort. The T2 Plus adheres superbly to the inner contours of my ears, and despite the aluminum build I barely felt their weight. Another bonus is I could lie on my side while listening, thanks to the petite earpieces and slim profile. I had to think way back to InEarz Audio’s Zen 4 for similar levels of comfort.

Make no mistake, T2 Plus offers God-tier levels of comfort, approaching the realm of custom IEMs. Bear in mind that T2 Plus is double-vented, so they don’t offer much by way of isolation. Quieting of external noise is average at best, so this won’t be your bestie during a commute. Ambient hums and whirrs are audible, and you’ll need a quiet environment to extract the best out of T2 Plus.

You can, however, block off the vents near the nozzles with tape, which improves isolation and elevates the bass. While some users are satisfied with the end result, I much prefer the original sound signature, because this mod congests the soundstage.

I'm not sure if he's your... type.
I’m not sure if he’s your… type.

Sound Quality
The original T2 is a shining beacon of the budget-priced neutral monitor, and attained legend status, fortune and probably free tacos for life by fulfilling a niche. We all know lightning doesn’t strike the same spot twice, so what does T2 Plus have up their sleeves?

Overall Sound Signature
The T2 Plus veers from the original formula in pursuit of a more accessible, all-rounder signature. It’s neutral-warm with an eye on technical nous and an ear for musical euphony. Aiming to be both a neutral monitor and something to kick back with at the end of the day, did Tin HiFi bite off more than it can chew?
Fortunately, T2 Plus does a lot of effective and pleasurable chewing. The signature comes together splendidly in terms of coherence and balance, with slight emphasis in the midbass and upper mids regions. The bass is mildly enhanced but manages to be both quick and tidy, the mids is a familiar neutral playground, while the treble, while unquestionably detailed, has smoothed-off peaks to soften the blows.

For detail nuts, the texture throughout is resolute and palpable. For realism addicts, T2 Plus’ tone is accurate and true, if just a bit on the dry side. By all accounts, this reads like a dream come true, but potentially alienates the original fans who grew to like the unique, neutral-bright T2, a rare sound at the $50 price point. The T2 Plus is an interesting case study of what happens when you try to please everyone.

Listening Conditions
Critical listening was done after 100 hours of burn-in. I’m not sure what NanoPure does to the T2 Plus (if anything, the name belongs in cosmetics), but I’m taking no chances, so the full burn treatment they get. The principal review rig is FiiO’s M15 player, with the supplied cable and stock medium ear tips.

Marriage, as they say, is a two-way street, but many hop into a marriage hoping their partner would change, lol. Longtime followers of Tin HiFi can rejoice because they listened to your feedback, and here’s your healthy, bottom-enhanced T2 Plus. Boasting a more robust and heavier bass section compared to its predecessors, T2 Plus’ bass provides much of the signature’s warmth and fun factor, and it can be intoxicating.

I'm not drunk, you're drunk.
I’m not drunk, you’re drunk.

The sub-bass reaches deep enough to tickle your throat, and although not a physical, take-no-prisoners rumbly sub-bass, plenty is audible. The midbass becomes the focus of the region, rising beautifully and decaying quickly with judicious amounts of punch and slam. Notes are polite and round with generous layering and details galore.

Timbre is natural and precise on the whole, if just a bit dry. The T2 Plus is conflicted between sounding Diffuse-Field neutral professional or punchy and fun, and most times you get a bit of both. And this is why, kids, every successful marriage is the direct outcome of joint compromise. The middle ground is always best, but the amount of control might frustrate bassheads who just want to let loose.

When push comes to shove, the bass manages to convey warmth while maintaining Tin HiFi’s signature cleanness. Impressive.

Like Switzerland, the mids are as neutral as they come. Walking the tightrope between technical ability and musicality, T2 Plus uncovers a lot of detail, but isn’t afraid to let you enjoy yourself. No not that way. The mids are neutrally located and possess a laid-back demeanour. Notes are well-delineated, and possess a soft, delicate texture that is effortless and never offends, though a bit on the lean side.

The mids stay mostly flat, except for a rise in the upper mids for clarity. Tonally, T2 Plus can pat itself on the back, sounding uncolored yet true-to-life while showcasing a smooth musical flow. If anything, the mids might be accused of playing too safe. Vocals sound accurate and clean, but don’t engage emotionally, like singing to pay the bills. Instruments, particularly cellos and acoustic guitars, lack the last bit of richness to tug at the heartstrings.

T2 Plus’ mids chugs away in a workmanlike manner without a worry in the world. Where it lacks in finesse and style, the T2 Plus makes up for in discipline and grit, a doggedness to relay every musical tidbit without fail. It’s highly competent with no real weaknesses, but had it more character, urgency, or a bit more feeling, we’d be dealing with honest-to-goodness world-class mids right now.

I always thought deflowering meant a trip to the florist.
I Always thought deflowering meant a trip to the florist.

Macklemore once said when caught rummaging through other people’s garbage, “one man’s trash is another man’s come-up.” The man got no shame, but his words make sense. The steady humdrum-ness that are unwelcome in the mids are precisely the attributes that take the treble to noble, lofty heights.

Like the foam on top of a hearty stout or the froth of a cappuccino, the treble has a smooth and airy finish, with sharp edges rounded off to produce a beautifully refined sound. There is no lack of clarity either, as each note is well-defined, topped with plenty of shimmer. The upper end is never harsh, and extends above cleanly without artificially increasing brightness.

Cymbals, bells and percussion carry a sweet tone, a tuneful remedy to those averse to treble harshness and sibilance. You can finally listen without fear despite Tin HiFi’s previous penchant for sharp cheddar, I mean treble. And while it could have been more crisp and precise, it might spoil the pleasing tone and balance the T2 Plus treble currently possesses.

Soundstage and Imaging
Like a modest mouse, T2 Plus doesn’t boast massive, stargazing dimensions. In fact it squeaks by with decent stage width and depth, never outright becoming a highlight. The stage size is far too common at this price range to be worth a mention. But far from doing shoddy, thankless work, T2 Plus keeps its stage absolutely pristine and immaculate, like Will Hunting as an over-performing janitor.

Helped by the lean, limber notes and a rapid decay, the stage is kept spotlessly clean with a tar-black background. There’s a realistic sensation of space and air as you scrutinize every morsel of musical information, kept apart with brilliant separation and imaging capabilities. Despite the average head-stage, the layering and neatness is anything but, and deserves special mention.

*Of course* you saw this coming.
*Of course* you saw this coming.



TRN’s VX pitted against the T2 Plus is a contrast of philosophy. The VX is stuffed full of drivers to handle all frequencies of the sound spectrum, while T2 Plus just needs one DD to do the deed. The VX starts off as the aggressor, boasting a big, bad, physical bass and a brighter treble. Sub-bass hits are felt and heard, while treble extension is higher and airier than the Tin HiFi.

Unfortunately, VX comes across as more unhinged too. The messy bass tends to bleed, compared to the neatness of T2 Plus, while the treble is peaky and harsh. The bass bloat and general in-your-faceness of the signature congests the stage as well, sounding claustrophobic next to T2 Plus’ immaculately tidy head-space.

T2 Plus presents music in a laid-back manner, with a smoother, more coherent musical flow that doesn’t wow at first, but rewards with more listens. Most importantly, it strikes where it hurts most, with better timbre and accuracy than the TRN. TRN’s mids suffer greatly in comparison, with grainier notes and shoutier vocals than the more accomplished T2 Plus. Suffice to say, I reckon Tin HiFi’s latest the easy winner of this exchange.

Audiophile bait. Works every time.
Audiophile bait. Works every time.

When “Oppoty” strikes, you listen. The butt of packaging jokes everywhere, BLON’s budget wonder BL-03 is serious business in the sound department, with one reviewer even claiming it outperforms Vision Ears’ VE8. I think it’s hogwash, but like the Dude would say, “that’s just like, your opinion, man.”

Giving credit where it’s due though, BL-03 rules the roost in the mids department. The technical proficiency and neutrality of T2 Plus’ mids are given a soulful, full-bodied push. As a result, the BL-03 sounds more emotional and arresting despite T2 Plus’ best efforts. This is also semi-prevalent throughout the signature, with T2 Plus being the more technical of the two, while BL-03 the more musical.

Where I believe the BL-03 falters is in the flabby, uncontrolled bass. The sub-bass ringing and midbass thickness can sometimes overpower the music and distract the listener. The BL-03’s smaller, messier stage also means it has trouble negotiating complicated musical passages, something right up T2 Plus’ alley.

If you can forgive the T2 Plus being just a bit drier and thinner in the mids, it is the better performer of the two, owing to a more balanced and refined sound signature. The higher resolution and readiness to unearth details help too.

“Hello darkness my old friend…”

Final Words
Great cuisine is a perfect marriage of taste and texture. You might have your own preference, but truly memorable cooking requires both to be outstanding. I once ate a block of tasteless gelatin because the texture was so unbelievably good, and that is why I only review audio. Similarly, a groundbreaking audio product is a combination of tone and technicality, the two tenets of sound quality.

Tin HiFi’s T2 Plus might seem unnecessary to some. Being the third iteration of a classic product sounds like a cash grab, but the final product is truly greater than the sum of its parts. Picking apart the sound, you might find unpleasantries here and there, but taken as a whole, few can rival T2 Plus’ coherency and subtle tuning genius. You won’t stop listening after the first track, and before you know it, you’re hooked on their voodoo.

Even discounting the sound, the T2 Plus represents a product with stupendous value for money. Witness the marvelous design, first-rate build quality, and the devilishly satisfying fit. No other product in this price range that I know of hits solid home runs in every department like this does. The T2 Plus is the total package that should step out of the original T2’s shadow and forge its own storied path.
Great review! I honestly really love reading your writing even if I don't agree with everything, but that's just the way audio reviews work!
Although I have the T2 plus since they came out, I was looking for their review in order to compare it to mine, and found yours on head-fi.
It was a very engaging read even if I don't agree on some points (audio is good because of this as well): your way of describing the sound while inserting some humorism here and there is unique.
Will wait for your next reviews! :)

100+ Head-Fier
Pros: Nicely calibrated warm tonality.
Good high section.
Cons: Slow bass.
Too polite.
Tips may require rolling.
I got this pair of TIN T2 Plus as a review unit from my friends at KEEPHIFI (www.keephifi.com) entrusting me to an unbiased analysis and openhearted subjective evaluation, which is what I’m reporting here below.

You can purchase T2+ either at Friendly Audio Store (Keephifi official store) or at Amazon **** Store.

My descriptive considerations at the bottom, let's start with the tabular analysys.

Test setup

Sources: Hiby R5 (Single Ended and Balance Ended port) – Fiio X3-mkIII – Tempotec V1 + Fiio BTR5 / Anaudiophile ESS DAC dongle / Apogee Groove
Radius Deep Mount tips
NiceHCK 16core High Purity Copper balanced cable
Lossless 16/44.1 – 24/96 – 24/192 FLAC tracks.

Signature analysis

Warm tonality in an accurately balanced signature. The care in the horizontal calibration / compensation of the various parts of the spectrum is probably the single best part of the product. The presentation comes across very coherent, and a pleasure to listen to.

Sub-Bass Modestly rolled off but still nicely present per se. It’s much better than what mid-bass lowend’s allows me to hear most of the times.

Mid Bass Slow transients make low mid-bass “fat” and quite invasive on many tracks. Personally I wouldn’t like this even if it were less evident. Even offsetting my preference, the effect is not nice in general.

Mids Overall a bit behind, they are actually quite nicely rendered with particular regards to the high-mids, both per se, and due to mid-bass relative veiling (see above).

Male Vocals Males clearly benefit from the general warm tonality, although not presenting particularly elaborated texture. They resound better than what they actually deliver, but I wouldn’t call the bad either.

Female Vocals Better than Male, Female voices do clearly benefit from the adjacent treble section quality. They are neither behind nor forward, on the lean side although not thin, quite defined and pleasant for my taste. No shrilling nor squeaking is present.

Highs Together with general balancing, this is in my score the best part of the presentation. Opposite to bass, highs transients are on the fast side, air is quite present and we have good extension and an overall very pleasant rendition, with quite some vividness, yet always free from peaks and offensiveness.


Above average but not more than that. More horizontal than deep anyhow. For the price bracket something more could have been done here.

Imaging Quite precise, unlike soundstage this is above average on this price bracket

Details Sub-average due to low mid-bass invasiveness (see above)

Instrument separation Identical notes as for “Details” apply: T2+ tries to show me some serious competence on rounding out each instrument, but the low mid-bass part of the tuning hides some of that.

Driveability Relatively easy, I can drive them at more than competent volume and open-ness even with a battery-less DAC dongle.


Aluminum alloy housing, with a nice satin finish.

Fit The general tear-drop shape is quite rightly sized and totally smooth-edged, making concha-level fitting easy probably for most people (me included). On the other hand nozzles are not long at all so depending on the general ear shape and/or on personal insertion depth preferences stock tips may be absolutely inadequate. Such was indeed my case, and after quite some rolling I ended up having to adopt Radius DeepMount eartips. Another important thing to notice is the presence of two vents, one of which is at the very base of the nozzle, which may end up occluded (totally or partially) resulting in a much darker sound depending on eartip choice and/or insertion depth.

Comfort Once the right tips are selected, comfort is actually great.

Isolation Once fitted and properly tipped, T2+’s shape provide above average passive isolation

Cable Supplied with a single-ended 3.5mm 4-core SPC cable with a very nice-touch kevlar sheath. Not tragical like other TIN stock cables (T4, anyone??) it does not shine any bright light either. Worth an upgrade for sure.

Opinions and considerations

Overall evaluation (1)
T2+ is not one IEM I fell in love at first sight hear with but this is more due to my personal tastes than to any severe product fault honestly. The two aspects that keep me from having chills are the slow mid-bass, and the “too much inoffensive” general presentation.
T2+ is very mild, accurately balanced, warm and relaxing. Some may heartily love them for this, actually.

Can we do something with that bass ?
Applying an EQ mitigation (even via a simple Graphical EQ) on 63Hz and 125Hz the situation gets significantly better. Bass suddenly gets less egocentric, with instant positive impact on mid-bass instrument presentation, much improved detail retrieval and much sharper instrument separation.
However (!) a correction heavier than -1dB will screw T2+’s well done horizontal balancing making trebles too evident. At -1dB low mid-bass is still too much present for my tastes, but even with that modest change the overall result is indeed much more pleasant to me.

Pairing (1)
The above sound analysis quite accurately relates my experience while pairing T2+ with Hiby R5 (both single ended and balanced ended), Fiio X3-mkIII, Fiio BTR5 (both single ended and differential ended) and Anaudiophile’s ESS DAC dongle – these latter 2 devices USB-docked onto my Tempotec V1 transport.
There are of course some differences from one source to another, but nothing life-changing:
  • ESS-based BTR5 and Anaudiophile DACs give a bit more forwardness to vocals on T2+, compared to Cirrus-based R5
  • BurrBrown-based X3-mkIII adds its warmth to T2+’s making it furtherly colored in that direction. In my books this is not a desirable variation, but that’s ofc my specific preference. YMMV, as always.
  • Balanced-ended amping on BTR5 and R5 grants a perceivably better dynamic to sound and tames bleeding bass a bit, contributing to gift some moderate but much required vividness to T2+’s presentation, which (as noted above) I find in general a tad too “polite
Pairing (2)
The situation changes dramatically when pairing to a higher-tier DAC/AMP like Apogee Groove.
Groove’s superior cleanness, clarity and definition makes as if a robust sheet of tracing paper is lifted off from the entire T2+ presentation.
When driven by Groove, T2+’s low mid-bass transients stay on the slow side, but gain an almost perfect control. As a consequence the EQ correction becomes totally un-necessary, bass autonomously losing virtually all of its bleed tendency. Mids come across a full step forward into the stage, which acquires an evident better clarity. Clarity in its turn converts into macroscopically better instrument separation and even more pleasant imaging.

Overall evaluation (2)
In the hands of higher quality equipment like the Groove, T2+ suddenly start shining of a diamond-like light, and rise to an absolutely outstanding level. They become detailed, controlled, authoritative and very engaging.
In such situation – although only in such situation – they get a solid place in the roster of my best ones below $100
