TinHiFi P1 - Reviews
TIN P1: silky pleasure
Pros: Spectacularly calibrated neutral tuning.
Superfast transients.
Relaxing, silky tonality.
Very comfortable (might be subjective)
Cons: Very crisp highs might not be in everyone’s taste.
Some might want more incisive bass.
Lack of emotion on some genres.
Significant amping required.
Unobvious tip rolling may be required to avoid sibilance (subjective).
As many following my notes know already, I don’t believe in “all rounders” and P1 is definitely not going to change my mind.

It excels – and phenomenally so – in delivering a supremely refined and relaxed acoustic experience. Every segment of the spectrum is rendered in an expertly micro-calibrated way: nothing is lush, nothing is too thin, rythm sections are rendered almost “gently”, although each single beat – bass and highs alike – is there and at the right time and evidence for me to feel it.

Solo or small group classical music – especially strings and pianos -, classic jazz, songwriters, folk & similia are at their top on P1. On a higher level, P1 is the right companion when I am in a self-centered, balanced mood, I am not looking for extra energy to input or expel through music, and I want to have music flow all around and through me effortlessly.

Once I managed to solve subjective sibilance issues by adopting SpiralDot tips, the sole small personal brush stroke I sometimes want to give P1 is a slight raise in low-bass (low-midbass + sub-bass) presence. Here’re the values I apply: Preamp : -4dB / Lowshelf: +2dB 80Hz Q:0,64 / Lowshelf: +4dB 150Hz Q:1,1
Wether I want to apply this or not essentially depends on the track or the genre really calling for it, then I do it liberally as such amount adds some welcome warmer body to the overall presentation while keeping P1’s low-bass inherent nature intact: superfast, unbloated, unbleeding.

Enough forewording, here's the analysis:

Test setup

Hiby R5 – Balance Ended port – JVC Spiraldot tips – **** 8*63core 6N Single Crystal Copper cable – Lossless 16/44.1 – 24/96 – 24/192 FLAC tracks.

Signature analysis

Neutral as for tuning, and superlatively smooth as for presentation. Planar drivers output impact is obvious: transients are lightning fast, everything is clear and polished. Every note is lean as can be – in the good sense, that is polished, unbloated yet bodied, not “thin”. TIN job has been to keep everything as musical as technically possible.

Sub-Bass Slightly rolled-off, and not even mainly that. Sub-bass notes are fast and textured, but they hit with kindness so to say.
Even raising presence by means of some EQ shelfing – which is very well received if applied – P1 won’t become the right choice for EDM or other strong-bass-rythmical genres.

Mid Bass More present than sub-bass yet of the same general quality. Notes are mildly bodied, very fast, but most of all they hit in a sort of gentle way. On P1 bass punches fast and precise but doesn’t leave bruises. It’s jabbing, not hooking.

Mids Mids are detailed at a very fine grain. Every single breath in voices is rendered with precision and clarity. String instruments are at their best here, this aspect is just phenomenal. On the other hand, transients are so fast that depending on the situation some emotion may be lacking.

Male Vocals Quite elevated and rather warm, they lean-back in terms of overall presence on stage due to the fast transients. Very detailed, simply put very nice.

Female Vocals Less forward than Males, and leaner too. Most of the positive things stated about mids do apply, barrred some occasions where Females come accross a bit too thin. It’s important to mention that I did have to sweat a lot to get rid of sibilance which – luckily – I identified being 100% connected with in-ear resonance, so I could get rid of it with appropriate tip pairing. After rolling many models, the ones doing the right cleansing trick in my own ear canal are JVC Spiraldots (only!). YMMV, and a lot so – many are so lucky as to not possibly experiment any sibilance with P1 no matter the tips

Highs Airy, clair, extended, sparkly and fast. P1 trebles have it all, and then some. Crispy textures offer a high level of detail sensation more as the consequence of clarity than of purely technical (and sometimes dual-bladed) detail retrieval.


A sensation of space, mostly in depth terms, is definitely there. My impression is not that of a huge room though, rather a non-crowded one.

Imaging It’s more layering than imaging what is superb here. Other IEMs make instruments feel more physically distanced one from another on the stage, while P1 “keep the group more closer”.

Details Again, it’s more clarity the word here, rather than detail. Hearing so fast, unsmeared sound gives a very refreshing sensation of cleanness.

Instrument separation All sounds are prefectly separated, and the separation is not even cut with a knife but rather smoothed with a thin grain file. As mentioned above P1 “keep the group rather close”, but no sound congestion is ever determined by instruments proximity.

Driveability Tough. Forget a phone, forget any entry level DAP. The absolute minimum requirement to let P1 shine is 200mW@32Ohm.


Very solid full metal housing, offering a very convincing durability sensation

Fit The triangular shaped housing, its modest size and the very long nozzles make it very easy to score a good and solid seal almost effortlessly, no matter which kind of eartips are applied – with the sole exception of stock “short + wide bore” silicon ones which are hilariously too short, so much so that the housing nozzle can easily protrude out of their front opening totally screwing the sound.

Comfort Extremely comfortable even for protracted sessions

Isolation Average at best. The housing is not large enough to fill the concha compeletely which is good for comfort but obviously suboptimal for isolation, which is also not helped by the presence of a front and a back vent.

Cable Per se, it’s a nice quality 5N OFC and copper alloy cable, if only not a masterpiece in terms of braiding. Too bad that it’s offered only in 3.5 single ended termination version, which is an obvious myopic choice considering P1’s significant power requirements. I instantly swapped it with a good balanced-ended one, while dedicating it to my T4 pair.

Pros: Impressive clarity , separation and details ,phenomenal vocals and stellar build quality at this price or beyond.
Cons: The beautiful case may be a little too big for some people but I find it very elegant. Some may have liked a cable similar to the T3 included.
A presentation on this item is top-notch opening the box when finds a fancy Display showing off the Tin P1 in it's shiny Glory and a beautiful hard case to carry them around in accessories also include various tips of different sizes including foam tips, a beautiful pure copper cable and then the P1 themselves.

Build quality is excellent although I thought that the T3's cable was just a little better. Still very pretty and durable.

Comfort is excellent as usual from Tin HiFi the angular shape I imagine would fit most years especially being on the smaller side of most earphones.

Soundstage is very interesting whilst not overly wide the sound seems to come from everywhere inside your head and almost 3d effect.

The highs are probably one of the best features of this unit having excellent clarity and separation without being overly harsh.

The mids are phenomenal and like the treble have a great quality of detail and clarity with great separation and a mild warmth to them. Giving that's probably the best vocal presentation of any IEM so far.
Bass is not overtly enhanced but rather neutral and its presentation until called upon the lower-end has outstanding details and a rapidness very tight with noticeable layering.

Over all these are a extremely transparent and neutral sounding earphone that highlights every frequency with great detail and separation befitting of a much more expensive pair of headphones. Yet are very pleasant and unique and the presentation of signature.

Although these are able to be driven by most sources given the 20 ohms impedance but because of the 96 decibels of sensitivity they tend to scale better with a amplifier/ DAC-amp or good Dap to get the best sound possible out of these the more power pumped into these the more magic you will get out of them.

Pros: Clear, fast and comfortable
Cons: Anemic low and sub bass. Really should be amped and best appreciated at higher volume.
I've had these for a little over a month. I expected more from the hype these are being given. With additional power from an amp, a change of cable (optional) and digging into your collection of tips, these are very capable and a very good listening experience. If you want lower bass extension shop elsewhere. Clear, fast and comfortable. Good build. I keep coming back to them and I am not disappointed.

TINHIFI (formerly name TINAUDIO) do not need presentation as they make their name from mouth to ears between audiophile due to the phenomenal popularity of their best seller earphones call the TINAUDIO T2. This constant praising about T2 still occur in fact, but they never sit on their laurels and continue to take risk by creating different technologies in earphones like hybrid dynamic+knowles BA drivers with the T3 and now….nothing less than a 10mm PLANAR DIAPHRAGM DRIVERS for their new flagship in-ear P1 model!!

The TinHifi P1 use super thin nano-diaphragm of only 1 micron thickness for their planar driver, wich promise wide dynamic response and super fast transient response.

Compared to other Planar earphones, they were able to fit this 10mm driver into a very small housing, making the P1 the smallest planer iem on market, as well as surely the sturdiest due to thick metal housing.

Now, it will be the first pair of planar iem I try, but i own a pair of Magnepan MG-2A planar speakers, so I have a little idea of the particular sound flavor of planar technology, it do not move as much air as dynamic driver but have more bass than a balanced armature and is able to deliver high frequencies range effortlessy. It tend to sound more flat, transparent and neutral than dynamic drivers too.

Let’s see in this review if TinHifi have been able to tune properly this drivers, wich is a very complex and difficult task.

The TinHifi P1 is priced 170$ but can be buy for 150$ on DROP (ps : plus a 5$ checkout discount AND 20$ signup Discount=125$!)

DISCLAIMER : I’m a big fan of Tinhifi since I buy the T2. I finally got the chance to review the T3 in the past and now I was curious to review the P1 so I contact them to know if they would be interested I do one. After a long wait, the P1 arrive a month ago. I wanna thanks Tinhifi for this free review sample as well as not puting pressure to influence the content of this review.

UNBOXING experience is surely the more luxurious one I ever had, and this include way pricier earphones packaged with less attention to presentation. The big black box is thick and classy, it look like a james bond gun suitcase (hum…) and when you open it you have a sober minimalist presentation that is a joy to look at. What you see is the beatifull metal earphones (and yeah, you are destabilize by how small they are) and a very elegant leather protective case (i smell it, its real leathers pals!). When you open this sexy protective case, you enjoy a rather nice 4cores OFC plated copper cable and generous amount of 8 pairs of eartips, including 2 pairs of memory foams one. At this price, I feel spoil by the number and quality of accessories.

CONSTRUCTION is very impressive and consist of 2 thick piece of metal stick togheter with a gold plated female mmcx connector that will never broke on you. Housing is extremely small and quite heavy for its size, wich proove the metal used is not alluminium but something way more sturdy. Cable is above average in term of quality and very similar to the one included with Ibasso T01. As i’m not a big fan of ear hook, I do not really use it.


DESIGN is near perfect, the housing is small, have a triangular shape that fit perfectly the ears and a quite long and thick nozzle. Only issue I have with design is that the metal border to stop the eartips is too near nozzle end, wich make eartips fitting a little unstable. To solve this I use long silicone eartips, but I would love to use wide bore eartips too wich is difficult as said.

ISOLATION is above average but it do not block as much noise as universal custom. Sound leakage is near inexistant due to little venting hole being in front of housing.


DRIVEABILITY is extremely capricious with the P1, you need quite powerfull amping to make them shine. With this earphones, i need a portable amp even with my powerfull Ibasso DX90, and they will sound better with my Xduoo XD-05+ or TA-10 that both have 1000mW of output. Don’t buy this if you plan to use them with your phone or even most of the DAP available on the market. More you put power in the P1, more the dynamic range expend as well as bass, imaging and soundstage. Simply put, they are the most difficult iem to drive I own, and this include the Final Audio E5000.

PAIRING (amped) give the best result with ultra clean and near analytical sounding audio source, not a one that is too agressive in treble, just very revealing like the Ibasso DX90 or Xdoo X20 (amped!). I do not suggest using warm audio source with the P1.



SUBJECTIVE SOUND APPRECIATION was mitiged at first due to how capricious about source power can be planar audio gear. Sure, i know they need some good power, but at 20ohm impedance I was thinking my IbassoDX90 will do well and I was wrong. So, the pairing quest begin and I find the answer with my Xduoo XD-05+ dac-amp that have 1000mW of power output. No more stockin your head soundstage, alive was not the dynamic, hourray! What suddenly it me is the transparence of timbre, wich isn’t thin neither grainy, just smooth and full and airy. Now, I recognize the planar flavor, treble is effortless and not peaky in upper region, everything is super resolved yet sweet tothe ears. Bass as expected was a little underwhelming in lower region, it do not move air, in fact, planar breathe soundwave instead of hitting your eardrum with it, but nonetheless the mid bass have good impact and weight wich make it. What really blow my audiophile mind is the overall imaging as well as extremely immersive mid range, violin and piano sound so sweet and gently polished.

SOUNDSTAGE is just enough wide to step out of your head, tallnest is above average as well, but most of all deepnest have no limit and give alot of extra (much needed) spacial freedom.

IMAGING is uniquely presented with the P1, its effortless in the way it can add transparent sound layer and even if its show in a rather intimate way, the level of accuracy of instrument placement is extremely refined and lively but not very realist or spacious. Its moreabout adding sound layer that properly place them at you right and left. Everything feel very centered with the P1.

CLARITY is natural, never forced, slightly organic and more revealing in tonality color and definition than texture and micro details. Mid range have extremly transparent presentation while the upper high are sharper in definition. This type of clarity is more for active listener than passive one waiting for a clinical presentation of their music details.

TIMBRE is gently wooly and velvety in a rich appealing way, not in a negative way, as if the texture was polished to avoid grainyness but keeping its contrast. Its thick as clouds, keeping lot of natural air in its soundwave. This type of timbre is unique so i can’t compare it to any other earphones I own. But it tend to give a sens of breathiness to female vocal.

PRaT (Pace, rythm and timing) is on the soft gentle side, but have extra energy and attack in mid bass and upper treble wich make percussion quite lively and accurate tough mid range instrument like piano cannot follow the pace as fast and tighly.

LOWER END is a little rolled off around 40hz and do not move lot of air, its more about a flat dryish but well define kind of sub bass. It have body, but not particularly textured, more about round presence that can be overshadow by more hefty mid bass.

MID BASS is well rendered, have good weight and punch, its round and transparent but not particularly fast or tigh, it do warm lower treble a little but in a layered way that avoid serious veiling or messy mixing. Even if punchy, its quite soft and not the more energic or foward mid bass, kick have a natural sens of weight and we do not struggle to hear it, this work better for jazz than fast rock. The P1 are neither suggested for basshead or bass lover, listening to any type of electronic even IDM isn’t very exciting. Acoustic bass sound better than digital bass, tough slap bass lack grip and attack too. Cello, piano and acoustic bass sound enough good due to good sens of body and thick transparent presence, but the texture isn’t very revealing.

MID RANGE is my favorite part of the P1, again, with a very distinctive planar flavor to it. I consider the P1 as mid centric with extra upper highs sparkle, wich make the mid range laid back in attack but fowards in presence. Its revealing yet smooth and warm in tonality. When I listen to folk, i like the mix of guitar sharpness and vocal sweetness, but when I listen to jazz or classical, it depend of mix of instrument to achieve an appealing musicality. Piano do sound marvellous -weighty, thick and transparent-, sometime violin too even if it lack bit of texture and proper energic attack. For vocal, it depend, male will have more warthm and fuller body while femal signer will be a little thinner and more recessed. What is fascinating with the mid range is how effortlessly the different instrument play togheter keeping great tonal balance and clarity with an intimate laid back aerial musicality.

TREBLE is particularly crisp and sparkly on top, wich instrument like harpsichord show greatly. For example, when it play in mid range or lower treble register, the clarity and attack is rather ratained and lack natural brilliance, but when its in upper register harpsichord or acoustic guitar are greatly defini with great snapiness and natural decay. This upper treble push tend to put fowards percussions line wich mix perfectly with kick drum but tend to overshadow mid range instrument. Snare is a hit or miss, in the sens it will sound more high pitched than it should and lack roundness. I consider treble balance to be a little too peaky sometime, but when the music fit for it, the result can be phenomenal.

SUB BASS : 7/10

TREBLE : 8/10

Vassilis Tsabropoulos & Anja Lechner ¨Melos¨,¨Song of Prosperity 1¨

Okay, there two songs in this video (its now complicate to find music on youtube so this is what I find). Anyway, both is a duo between a great pianist and excellent cellist. Listening to them with the P1 is ethereal, transparent and aerial. Unlike some other iem that tend to shadow piano because of too thick or textured cello, the P1 offer a lighter and more contemplative approach. Cello is full sounding but mellow and transparent as well, its not very textured but we hear the smooth attack of the bow, some breathing too, but nothing that will tend to distract from overall tonal naturalness. Piano note float in they air and mix gently with cello layers, keeping its soft clarity intact. Mid range of piano is less snappy than upper range wich have more decay and brilliance. This type of listen is perfect the eye close so you let yourself drown in the liquid, sweet musicality with velvety transparence.

Geir Sundstøl - Kamelsnurr

The P1 love acoustic guitar as well as steel pedal guitar layers, and this track show it beautifully. Sure, their more decay and natural resonance in upper range, wich the first minute of the song show perfectly with the crips, extremely clear and brilliant note plucking, but when slide guitar is playing togheter its addictively transparent as well. Now, when the big heavy tom play, its suppose to sound weightier with longer decay, wich do not happen here and affect overall musicality. In other hand, with too bassy iem this would have dangerously veiled the other instrument. Everything sound addictively transparent and well detailed except the bass tom, but i rarely heard as much sound layer in such a innoffensive way than with P1.


VS BQEYZ Spring1 (140$) :

SOUNDSTAGE of Spring1 is notably larger, taller and more out of your head, while it lack the deepnest of more intimate P1. IMAGING being more spacious, the Spring1 have a more accurate instrument placement with a more holographic feel to it, instrument have space between them while the P1 is an addition of transparent layers, overall result is more lifelike and clearer with the Spring1.
BASS have more weight and texture, better attack making the Spring1 feel quite muscular compared to more relaxed P1 that lack sub bass extension. With Spring1 you do not struggle to hear bass line, they aren’t as transparent as P1 but resolution is better and thicker.
MID RANGE is slightly brighter and seriously more detailed in both texture and dynamic with Spring1 than more laid back and darkish P1, attack is more energic-agressive and timbre more textured too wich give a more immersive and lively sound for the Spring1.
TREBLE is more emphased in upper highs with the P1, wich give extra brilliance and sparkle but stole details in lower and mid treble that Spring1 deliver with plentiness, this tend to make the P1 sound a little more airy but unbalanced too.
All in all, these 2 iems are opposite both in tonality and timbre, P1 being warmer, more transparent with a tamed in attack V soundsignature while the Spring1 have a very energic W with tamed upper treble and extremely rich timbre.

VS FINAL AUDIO E4000 (150$) :


SOUNDSTAGE is just slightly larger with E4000 but still feel more intimate than P1 due to extra deepnest it have. IMAGING is quite similar but E4000 have more horizontale space between them wich make instrument placement more accurate and spacious than P1 compressed layerings.
BASS have more slam with the E4000 and a more U shape sound that tend to warm lower treble a little more than P1, attack is weightier tough mid bass kick is softer.
MID RANGE is slightly more recessed with the E4000 (when bass occur) but have brighter tonality, lusher timbre and better attack, wich make instrument like piano or violin grain in pushed presence, P1 is more airy, transparent and laid back.
TREBLE is more laid back with the E4000, but sound more balanced and detailed in lower highs. P1 have more micro details on top and serious emphasis in upper highs that give extra brilliance and sparkle the E4000 crualy lack even if the overall result is more musical and natural.
All in all, these two have some similarities, we can say E4000 is a more bassy, energic and balanced version of P1 with less transparent timbre and rolled off treble.



From what I read about other planar iem like the pricier Audeze isine20 or RHA CL2, the sound rendering of such drivers is near always polarizing, should it be about overall sound balanced, bass extension or treble emphasis, it will really depend about both pairing and music you listen to to get the best musicality.

The TinHifi P1 isn’t completely an exception to this Planar niche soundsignature but have the advantage of being very affordable as well as offering a rather easy to listen soundsignature.

Sure, it need quite a lot of power to get the best of it, but once you do, audio nirvana can sure happen time to time, with the right music, like well recorded jazz that will have very appealing mix of energic percusion, transparent bass and piano line and smooth transient response only a good planar driver can offer.

Tough I will never suggest this iem to bass lover, I sure think the unique sound experience it offer will please a good amount of audiophile, if not the mass. For those that search for an appealing mix of well layered transparent mid range and super crisp upper treble, I think its time you try the TinHifi P1 to taste the most affordable (and perhaps the greatest) planar iem on market today.

Sound wise, are these better than bqeyz kb100
I prefer OFC cable instead of included OCC. Mids become lighter and highest treble elevation smoothened.
Pros: Very linear signature with great tonality, very comfortable for long wear, doesn't elevate sub-bass or vocals
Cons: vocals not pushed forward, requires a powerful source
disclaimer: I was provided the Tinhifi P1 by Linsoul Audio in exchange for reviewing it. I have no financial interest in Tinhifi or Linsoul and have received no incentives or direction from either in the production of this review.

These can be purchased directly from Linsoul or from their Amazon Store here.

Unboxing / Packaging:

The P1 comes in a lift-top style presentation case in understated black and silver. Inside the box, the earpieces rest in the foam tray with the case in a recess below. The cable and tips are hidden inside the case or under the tray which gives the kit a nice clean look. The Case is leather wrapped on the exterior and suede on the interior with a magnetic closure and fits the P1 well but leaves little room for additional tips or other items. A wide variety of tips are included in the box as well with two sizes of foams, 3 sizes of single flange narrow bore silicones, and 3 sizes of wide bore silicone tips. This has become the norm of late and gives the user the option of enhancing bass with the tips (wide bore) or going for a more reference sound (narrow).

The shells are stainless steel 2 part design with the nozzle being integral to the inner half of the shell. The seam is visible at the mid-line of the shell, but fit is good with no gaps or glue visible and very little space around the mmcx connector where it mates to the shell. The Exterior is almost oval shaped with a wider rear than front. the triangle shaped decoration misleads the eye as the shape from the underside is obviously rounded with no corners to be found. Nozzles exit near the center of the earpiece with a steep forward rake and a fairly short nozzle that limits insertion depth and by extension isolation. Grills are recessed in the nozzles by about 1 mm and a ring around the outside provides for tip retention.

The P1 uses a 10mm planar-magnetic driver. Planar technology can be thought of as a dynamic driver that combines the voice-coil and diaphragm of a dynamic driver into a single unit which allows the diaphragm to move as a single unit, so air moves more evenly and transients are faster than a dynamic driver. The downside to planar drivers is typically they require more power compared to their dynamic counterparts as the magnets are now the size of the diaphragm rather than being a smaller unit behind it. The P1 has a nominal impedance of 20Ω and a sensitivity of 96 dB/mW but does require considerable power to drive. I found the P1 to be a limited pairing for phones and tablets as most required that volume be turned up considerably above the norm to adequately drive the P1. If you are planning on pairing the P1 to a tablet or phone directly, I highly recommend you audition them before purchase to make certain the device has adequate power to handle them well. I found the xDSD, XD-05, and Walnut V2 all were able to drive the T1 markedly better than attempting to use a phone alone. I think the P1 sits right on that border of needs an amp, so if in doubt, audition first or plan on using an amp.


The cable provided with the P1 is a 4 wire braid made of 5N oxygen-free copper from the straight 3.5mm jack up to the splitter and then exits as two pairs of twisted wires. The north end terminates in loose earhooks and mmcx connectors. Housings are chrome plated with the jack having an extra carbon fiber inlay. A clear bead slider rounds out the furniture. Other than my obvious preference for 90º jacks for durability reasons, I really like the cable as it is extremely flexible and very quiet without any issues with tangles. A velcro tie helps with that, but some others I have still require that you either baby them or untangle them every time out of the case. Overall, well done.

Tinhfii P1 FR.jpg


The P1 has a stereotypical (pun intended) planar sound. Bass is fast, clean, deep, impactful, and exacting. Sub-bass isn't elevated, but is very present even at lower volume levels and can be an almost visceral punch with volume at the upper end of safe listening range. Mid-bass follows linearly from the sub-bass and shares the same proportionality and tight control of the lowest notes. Lows just seem to flow from the P1 effortlessly. Speed contributes greatly to the bass as attack is instantaneous and decay nearly as quick. No bleed or bloom, and no obvious transition points from one thing into the next. Almost in spite of itself, the P1 manages to deliver enough warmth to keep it from seeing overly dry although it does certainly lean that direction.


Lower mids transition flawlessly from the mid-bass with no bloom, bleed, or even anything worth noting. It can be hard to identify the transition point as it really is quite seamless. Again the planar speed keeps everything tight with great control and above average detail in the mids. The one caveat is for those used to an upper-mid bump to bring the vocals forward into the mix, the P1 may well seem odd at first. It has no such lift and thus it takes a bit more effort to pick out certain details in the music. That isn't saying those details are not present, just that they are not forced forward into the mix where they are easily seen. The upside of this linearity is that everything fits well together and I feel no need to speak to female vocals being ahead or male vocals being thinner. Guitar growl is quite good, but here again doesn't linger long. Strings are rendered extremely well and the P1 may be best in class for those listening to a lot of string quartet or violin concerto.


Alright all this perfection has to stop right? A $169 in-ear cannot be perfect, can it? Well, no, and the treble is where the planar driver usually struggles and so does the P1, a little. The transition point from upper mids to lower treble is slightly more visible than the lower transitions but still fairly clean by comparison to others in its class. Treble stays fairly linear with the rest of the signature up through about 5kHz where it falls fairly sharply. A bump at roughly 10kHz adds back some top end sparkle and air. The P1 comes off as slightly dark due to the fact that we have grown accustomed to lower treble being pushed forward. The P1 is actually fairly close to neutral with the exception of the dip between 5kHz and 10kHz.

Soundstage / Imaging:

Soundstage on the P1 is a mix of its component parts. Planars are known for having good stage size and control, while closed back nearly sealed designs are generally regarded as the worst possible design for sound stage reproduction. There is one small vent behind the nozzle that keeps the P1 from being completely sealed, but it still acts very much as a closed model. To my ear, stage is fairly well shaped without being lopsided in any given direction but is fairly small in all dimensions. Think of it as similar to a good sized listening room rather than a concert hall and you have a pretty good understanding of what you'll get. Imaging is spot on with movements and spatial cues being superbly done. Layering follows suit as the speed of the driver keeps things from getting thick even when complexity increases. The other thing I noticed while listening for stage is that the P1 has a larger than average stereo separation and that spread can be mistaken for stage at times.

Thoughts / Conclusion:

The P1 is probably the best reference in ear below $200. It is as linear as any I have heard in the class and might give the Empire ESR a run for its money at times (although I think the detail level of the ESR is considerably better than the P1). Having said that, it isn't the boring reference we sometimes hear. The P1 manages to walk the line between neutral and lifeless quite well and never strays away from neutral or into lifeless territory. Will you like it? Hard to say. At times the reference signature lets every nuance and detail be heard and makes for a very interesting listen, at other times, that lack of anything splashy or any spill over from mid-bass into mids will make the P1 seem a bit thin even if it is technically correct. I think for those who like a darker, thinner signature with less treble lift than average, the P1 will fit very well. If you have a portable amp you love but hisses, the P1 also might be a good bet. I found that my Burson Fun tends to hiss with very sensitive IEMs (not what it was designed for, I know) but was nearly dead silent with the P1 so its lower sensitivity might help tame that for you too. As always, with so many good choices, audition as many as you can before purchase, but be sure the P1 is on your list.
Pros: Natural Trebel, effortlessly showcases micro details in all frequency ranges.
Cons: Very bass light. Needs a lot of power. Not portable really.

Tin HiFi really made a name for themselves with the release of the T2. I bought into the hype train and picked up the T2, and to be honest, at first I absolutely hated the IEM. At the time, my daily drivers were a set of old Ultimate Ears Triple.Fi 10’s reshelled into a CIEM, and a set of (also old) Westone UM3X. Both units seal well and provide great isolation. The T2 on the other hand, made almost no seal, fell out of my ear constantly, had very little isolation, and overall, sounded just...ok. Back in the draw it went, only to come out a while later with all the P1 hype. After some more tip rolling, I found that large comply foams got the T2s to stay in my ears, and the sound was much improved. They moved into my daily driver spot at work, and I have grown very fond of them. I skipped the T2 Pro and T3 given all the reviews mentioned that those IEMs were just different and not really upgrades. With 40+ IEMs, I don't need (or want) similar but different anymore. But now, the P1 comes along, and things get a lot different, and I was intrigued.

The Tin HiFi P1 shifts from a dual dynamic (T2 / T2 Pro), or a dynamic driver and balanced armature hybrid (T2), to a 10mm planar magnetic driver. Several companies have tried this driver (this exact one, or one very similar) but failed to get the tuning right (Tin HiFi sorta falls into this camp too, but more on that later). Tin HiFi with their new P1 seems to have come the closest to nailing the tuning compared to the competition, assuming the musings of other reviewers are to be believed. Having spent over a week exclusively using the P1, I can say I am in love with this IEM, but that love is only half of a love / hate relationship.


The P1 comes well equipped with the standard S/M/L silicone tips, in both large bore and small bore, as well as a large set and a small set of memory foam tips (Comply clones). Note, the foam tips are not like the non-memory foam tips that Tin HiFi includes with the T2. The P1 also ships with a leather (real leather?) magnetic closing flip top case. Personally, I would prefer a zippered clamshell style case, as I have found the case open and the IEMs loose in my bag more than once now. And finally, the cable, oh that cable. The P1’s use MMCX connectors (I really wish these were two pin), and Tin has included a cable that is a major step back from the T2 and T3 versions. The cable on the P1 has pre-formed ear hooks, a standard Y split, a useless clear bead for a chin slider, and an annoyingly loose braid on the lower portion of the cable. Also, I wish the cable were a bit longer, because (spoiler) these IEMs are NOT great for portable use, and given that you really need to be at a desk with an amp to use them, the cable does not have reach to facilitate that use case. Luckily it is detachable, so you can replace it easily enough.

Build and Comfort:

The P1 is built like a tank, making nice use of full metal housings. These feel like they will last a lifetime. The only grip I have about the build is minor, and it’s that the P1 shells smudge up with fingerprints very easily.

The shape of the IEM, and medium length stem allow for a nice fit and all day comfort. For the past few days, I have put these in my ears at the start of my work day, and left them in until lunch, about 5 hours, without issue. The same story repeats after lunch. I personally found the foam tips the most comfortable, but given that I do have to remove them from time to time to converse with co-workers, I have switched to the narrow bore silicone tips for ease of insertion.

Sound Signature:

Now on to the meat of this review, the sound! But first let's get some logistics out of the way. For starters, these IEMs need power. For the sake of this review, I will provide my interpretation of the sound when using the P1 with an external amp (FiiO E12A) and DAC (Venture Electronics Odyssey and Google Pixel USB C dongles). I tried a few other devices such as the FiiO E17K, my 2018 MacBook Pro, LG G6, and an older FiiO E7/E9 DAC Amp combo. Turns out, the P1 is picky with amps, and in my experience, sounded meh on all but the E12A.


This is where the P1 excels. Tin HiFi got the upper registers of this IEM tuned right. It delivers air and sparkle without fatigue or harshness. I have not experienced any sibilance. And the detail retrieval is simply addictive. The P1 brings out micro details in music effortlessly, and with speed and clarity that make the music very engaging. When listening to my favorite tracks while working (read: not critically listening) I found that I kept noticing details that stood out in the music that I would otherwise have to “listen” for using other IEMs.

I have played in several bands, had a drummer for a roommate, and seen a lot of live shows. I know what cymbals sound like. The P1 delivers cymbals with amazing accuracy, and it’s very satisfying to listen to. In short, the P1 crushes the treble game.


The P1 is a very vocal forward earphone, and both male and female vocals are delivered front and center, but without forcing other parts of the music into the background. I’ve not really heard anything quite like how the P1 treats vocals, and I have to say, I really love it.

I found the tonaily of the midrange to be very natural, never overly warm, never impacted by bass bleed, but sometimes it did come off a bit dry and clinical. The P1, without EQ (read: foreshadowing) is very neutral, and some (including me) would say it’s bass light, causing that added warmth many of us prefer to feel absent, and leaving a bit of a hollow sound in more complicated musical tracks.


Here is where the P1 takes a nosedive. The bass on the P1 is neutral, but just barely. Personally, I prefer a bit of a bump to the sub bass, with a more neutral midbass. The P1 delivers the neutral midbass, but lacks slam, and has poor sub bass extension. The IEM never feels dynamic in stock form. What bass is present is very well textured and detailed however, as the P1 gives the bass the same treatment as the treble when it comes to detail retrieval. This is a great thing, because with a bit of EQ this IEM turns into a whole different beast.

Imaging / Instrument Separation:

The P1 and that mini planar dynamic driver, as you may have expected, delivers sonics with amazing speed and clarity. This leads to fantastic imaging. You really get a sense for each instrument that is present in a mix. For instance, listening to fuzz rock such as Truckfighters, the bass line was very present, where as most other IEMs conceal it lower in the mix and force you to really try and pick it out. Orchestral records are a real treat as well with the P1, as you can definitively tell what is happening with each instrument section.


While the P1 delivers micro details and instrument separation very well, it falls short on producing a wide soundstage. The P1 never really delivers music with any of that fun “out of your head” feeling. This isn't uncommon for IEMs given that they’re shoved in your ear canal though, and I really didn’t expect much in this category.

That said, the P1 does manage to provide a deep stage, that lends to its ability of conveying quality instrument separation.


So where does that leave us with Tin HiFi’s newest, the P1? Well, it’s a great IEM with a lot of potential. Stock, It’s not worth the hype it initially received. But, and this a large but, with a little help it turns into one of the best IEMs I have heard, and my personal favorite for daily use with.

First, power. Give it good, clean power, and try several amps if possible. Second, EQ and / or bass boost. The FiiO E12A, on high gain, with it’s tastefully implemented 4db bass boost activated, does something magical to the P1. It takes them from neutral, dry, and analytical, to warm ,lush, dynamic, and oh so very engaging, all without any negative impact on the pros that the P1 possesses. Therein lies the problem with the P1. Stock, it’s ok at best. It’s terrible at being a portable IEM, and it really should be thought of more as a headphone alternative for desk / home use. But,when used in that situation, given a bit of EQ / bass boost, and some quality power, the P1 moves into a class well above its $169 asking price. This is not an IEM for someone looking for an all rounder, or that first high end piece. This is not an IEM for someone that wants to use it on a commute or outside the house. This is an IEM for the collector that wants something new and different, and knows how to put the work in to tweak audio gear to their liking. That is why the Tin HiFi P1 is the best set of earphones that I won’t recommend, but will love and use daily for a good long while.
@Khronos it should be fine if u run the P1 on R3 Balanced. P1 had a weird power requirement, it can get loud with low power, but it sounds really bad, the bass dips into the abyss, mid was dry as desert, staging & layering is a mess. When u give it more power, instead of getting loud, it's as if the sound was opened up, the layering & staging is really different. I've tried several dap & amp, u can utilize p1 full potential using device that had about 120mW.
I've got about 500 hours on my P1s now and they are the lovliest IEMS ive ever heard or owned. They definitely improve with time "Burn-In" the bass has really developed nicely and with the right tip (for me comply T400) they are simply irresistible. These $169 P1s have beaten the tar out of my SE 846, Xelento, Shcockwave and a few others. I love them. Give them time and a bit of EQ and you will too. Any my shanling UP2 or BTR3 drive them easily for portable use.
Wow, their live-like sound are impressive. I can say P1 planar beats all my DD or BA in this area. For some music genres I have to EQ them .... for example for rock music I like more bass and more upper mids.

Pros: Best out-of-the-box tuning for a planar iem at any price point that I've tried
detail and resolution is quite good at this price
clean design
very nice case
Cons: upper treble is bright
sibilance risk
fit can be challenging
small soundstage can cause congestion in busy tracks

Planar Magnetic headphones have been around for decades at this point. My first taste of planar magnetic headphones was the Fostex RP series, which is popular in the modding community and as a budget headphone with very low distortion. More recently, a small handful of companies have attempted to micronized the planar driver into a smaller form-factor for in-ears including top names like Audeze and RHA with varying success.

In my personal experience, I have owned and tried out a few of these – namely the Audeze iSine 10, the RHA CL2, and a universal and custom version of the Unique Melody ME1. These three IEMs have unique sound signatures from one another, but all have some tuning flaws that really require equalization to perform well. The Audeze series even includes a hardware-based DSP in the Cipher cables for iOS devices, as well as the Reveal plugin for computers.

So when Tin Hifi, makers of the popular T2 and T3 in-ear monitors, announced they were releasing a 10mm planar driver at budget prices, I was not only surprised, but also excited to hear how it stacks up. The CL2 is the closest to the Tin P1, as they are both closed backs. Now, I just want to mention that there have been a recent wave of Chinese planar IEMs that have come out including the Toneking BL1, **** MT100 hybrid, Nicehck F3 hybrid, Sendy Aiya, a planar from AAW, and a new one in the works by Danico Labs. I have yet to try any of these new wave of IEMs, but the reviews for each one of them (sans the unreleased Danico Labs one) have been less than appealing, each with their own unique flaws – much like what the first wave of planar IEMs experienced.

First off, I like to thank Lillian from Linsoul for providing me not only this production pre-release unit for review, but also an earlier build which was re-tuned based on initial feedback from reviewers. It seems like they’ve taken this to heart, as the new tuning is a significant improvement upon the original. I will post some links at the end of this review for presale purchasing.

Build Quality, Accessories, and Fit

The Tin P1 comes in a very cute mirrored metal shell that is very small and thin, but has a long wide nozzle. Inside houses the 10mm planar driver, and the housing also uses mmcx connections. The build is very well made, and looks from afar like the head of a golf club.

Accessories are very standard here. It comes with 2 sizes of foam tips, and a selection of silicone tips in varying sizes and shapes. The package also comes with a faux-leather pop-up case that’s pretty nice to use, and reminiscent of a narrow watch box.

I found the shell design to be less than ideal for fit in my ears. The long nozzle does not make up for the shallow and small size of the design, and getting good tip seal was a challenge. I struggled trying to find the right tips that remained in my ear and provided ample seal. Not getting good seal with these really deteriorated the sound quality and it’s very, very noticeable when you get that right tip in place. I ended up using Final Audio E tips, something I commonly have been using with other IEMs.

Power & Sourcing

This is important. The P1 has 20 ohm impedance, but it’s sensitivity is 96dB/SPL and that means that it is a little less efficient and more power hungry than many other IEMs. They still are nowhere near as power sensitive as an over-ear planar, but the P1 does require a bit of juice to make it shine. I did a bunch of testing on various sources and can safely say that more amping power provides a much better experience in terms of dynamics and bass response.

First off, the Google Pixel USB-C audio adapter is very inadequate for the P1. At max volume on my Essential PH-1 phone running stock android, I was only able to get it to lower than average listening volume. Luckily, the Apple lightning adapter proved much better results using my iPad Mini 4 as a source.

I used the RME ADI-2 DAC and I felt it was a little weak and underpowered using it’s IEM output, but at the time, I wasn’t completely settled on tips yet, so that could have played a large role in what I was hearing. I did have very good luck using a desktop Pete Millett Starving Student Tube Hybrid amp, which was a DIY creation. This one provided plenty of power and really made the P1 show it’s true potential.

I finally received the Massdrop THX-789 amplifier, and my first trial was with the RME ADI-2 DAC paired with it using balanced connectors, and with the Tin P1 plugged into the balanced XLR jack (using a 2.5mm cable and adapter). I found that I was about 10-11 o'clock on the dial using Medium Gain (Setting II) on the amp, with the RME at -10dB volume.

On the DAPs front, I own the Astell & Kern SR15 and Pioneer XDP-300R. Both were pushing higher volume requirements than most of my other IEMs, and even more than the Etymotics ER2XR that I purchased recently. The ME1, in comparison, is much less power hungry, in terms of pure volume loudness.

For bluetooth audio, I use the Radsone ES100, which features both single-ended 3.5mm and balanced 2.5mm outputs. Here's my findings:

ES100 with P1 - Source at 100% volume

  • 3.5mm : I'm at a good low listening volume at -15dB (-60dB to +6dB scale) but can definitely get louder if i wanted to.
  • 2.5mm : I'm good at about -15dB volume as well
  • in both cases -10dB would be my "fun" listening volume.
Sound Check

The P1 has neutral-leaning warm and laid-back tuning that will remind folks of a Diffuse Field/Planar bass and mid response up to 1K and then a more tone down upper mids and treble presentation that is reminiscent of the Campfire Andromeda tonality with less bass emphasis. The treble is definitely boosted above 10KHz and this is quite audible in my listening.

The bass response is slightly rolled off, and if you do not have a good source, I felt that it was a little weak and missing something. When amped correctly, the bass is much more present, and has decent sub-bass rumble and pop. This tuning is more punchy that I expected, but still is rather lean compared to most other IEMs in this price range, and should be rather familiar if you like the Tin Audio T2/T3 bass response.

In most songs, I found the bass presence to be apparent and available. It supplies clean bass notes and good decay speed, albeit a tad fast. This does help it stay taut and controlled. It doesn't have a lot of subbass boost, but it's present enough to provide a little rumble.

Closing the front driver vent, near the nozzle, helps flatten the sub-bass and improves it’s weight and performance. I do not know if this affects anything with ear pressure or any other long lasting effects.

The mids are generally coherent and good. They are forward, but sound slightly recessed in the background, if that makes any sense, especially when compared to Etymotics or the Moondrop Kanas Pro, partially due to not having as elevated upper mid-range and lower treble response, but they do not sound bad at all. I found some female vocals to sound nice and pleasant with no sibilance issues, with the P1 going through my normal gambit of Stevie Nicks in Fleetwood Mac, Norah Jones, Molly Rankin in Alvvways, Lauren Mayberry in Chvrches, and various country singers like Catherine McGrath and Allison Krauss. They are pushing the boundaries and you can tell, but it's controlled enough with that selection of music to not cause any major problems.

However, later on, I started listening to some recommendations from reviewer Crinacle, and found excessive sibilance artifacts when listening to Rhianna tracks and some other songs I found in the pop genres. This sibilance was something I had already noticed in other songs, but really became apparent on some of these EDM and electronic-mashed pop tracks.

Male vocals sounded a little bit off to me though, like they are slightly veiled and almost having the same effect I was experiencing with female vocals on the IO but not nearly as bad. For example, I found Chris Stapleton to lose a lot of bite and grit. That said, this isn't a deal killer, as it's not as noticeable unless I A-B with other IEMs, and perhaps I prefer a little bit more warmer lower mid-range.

Sibilance and treble shrills could be related to the treble boost in the upper region, which I thought I may be immune to with age and concert-going life in the past. When I first heard the original test model of the P1, I didn’t notice it at first, but I let another audio-nerd, with ears half my age, listen and he quickly mentioned how shrill and bright the treble effected the music he was listening to. Since the tuning of the P1 was so “wrong”, I didn’t quite pick up on it then as there were many other issues with the P1 at the time. Now that the biggest issues with the P1 have been resolved, the treble edginess stands out, and can quickly make this IEM fatiguing and sound a little grainy and strained.

I find it occurring in songs like “Get Out” by Chrvches, and “Juice” by Chromeo, amongst many others. It may lend itself to the electronic-pop and EDM type tunes more so than rock songs, but it’s still noticeable even on rock tracks. I found some Smashing Pumpkin tracks to be more bright than normal with Billy Corgan’s voice just a tad more “weird” than normal. The piano, guitars and falsetto-ish voice of Andrew Wood from Mother Love Bone on “Chloe Dancer” all have a lingering high pitch shrill to it that I can find a little annoying.

Hi-Hats and Cymbal crashes have that tizzing sound from this treble spike that can add to the aforementioned fatiguing issues.

If you can get past that, the resolution is actually quite good, if not excellent, as I’d expect from the low distortion planar driver. (I did not measure distortion, but just going by generic planar experience)

The soundstage is slightly less than ear to ear (or about 0.85 MCM unit), which makes some busy tracks sound congested if there's a lot of instruments playing at once. This is partially due to really good detail retrieval and clarity at this price point, if not much higher price points. With all the little nuances of instruments present, and all of it coming at you at once, the width does make it a little over-bearing sometimes, like in "Contact" by Daft Punk. That could be a good thing or a bad thing depending on what you like. But again, the resolution is really fantastic at under $170 and I have nothing to complain about.

It’s been too long since I’ve owned the iSine 10 to really compare the two, but I feel like I am more impressed with the resolution of this one than I was with the iSine. There have been several moments in songs that I heard new things in more clarity that I have not heard before on most of my IEMs, and would only hear in my most resolute over-ears, so that is impressive. I don't remember feeling that impressed with the iSine 10 and it's definitely more resolving than the ME1 that I own. The CL2, with it's sharp 4-5K spike does resolve quite well as well, and these may be on that level of resolution, but without that harsh peak and the amount of treble veil.


So with the stock tuning out of the way, and now that I’ve mentioned the flaws with it, I will have to say that the P1 is the best planar stock tuning I’ve heard to date. It’s only a sample size of 4 IEMs from larger companies, but it’s something to point out. Tin is the closest one so far to hitting it right. It’s not perfect though, as mentioned already. And just like the other IEMs I’ve tried out, the use of equalizer can really help make these sound much better than the stock tuning.

Throwing a low-shelf filter at +3-4dB at 125Hz, and then boosting the 2-8KHz region a couple dB and reducing the 10KHz and above by (a lot) of dB can really make this IEM sound quite pleasant, at least to my ears. I also threw a slight dip between 500 and 1KHz to give it a very shallow U-shape curve, and it’s getting pretty close to my ideal target curve, and I find the P1 to be quite good, if not outstanding for $150-170, taking on the Audeze giants.

General Overall Impressions

That was a lot of stuff, so quickly recapping my impressions thus far:

I found the build quality to be very good. The design made fitting and getting ample seal very challenging for me, but I was eventually able to find a good tip combination. They are comfortable, but not exceptionally good. I still like the comfort over T2/T3 though.

The P1 is very power hungry for an IEM, so some phones and especially the Google Pixel adapter may not cut it. I thought the lightning adapter for iOS was good though, and quite clean. A clean DAP source would be ideal, and it scaled even better with desktop amps.

Finally, the tuning has shortcomings that can be overcome with Equalization. Even without it, the P1 is the best out-of-the-box Planar IEM tuning I’ve heard yet, in my limited experience with planars (check introduction for the list). The subbass is rolled off, but can be patched with vent hole mod or eq. The mids are mostly good except male vocals sound recessed and tingy. The treble is consistent but then peaks up very bright in the upper registers which seems to affect how splashy some instruments sound, which can be very fatiguing.

Resolution, width, depth, and general technicalities is excellent for this price range, and is only improved with equalization.

So, there’s my short impressions of the Tin P1. I hope I gave you, the reader, a good overview of the pros and cons of it. There are definitely trade-offs here, and you’ll have to weigh your decisions accordingly.

For me, I have some mixed feelings about it. I would prefer to not have to EQ but I have the ability to. The stock tuning, even without it’s treble flaws, is still not my ideal sound, but it does follow the popular Andromeda mid-range and lower/mid-treble tuning with less bass weight, and that should make a lot of people happy. That’s not my ideal or preferred tuning though, as I mentioned in a previous Andromeda review posted last week. I like a little more presence region boost (2-5KHz) and the P1 doesn’t do that without EQ.

So, at the end of the day, I still give this IEM a cautious and mild recommendation. I would stay clear if you do like a little more bass emphasis or tend to listen to genres like EDM, modern pop, and hip hop and rap music. The leaner subbass and upper treble elevation may make those genres less enjoyable and in some cases sharp. I have been enjoying listening to it, despite its flaws. It's a very intriguing IEM at this budget price point and is really a sign of how things have changed in the headphone/IEM market in the past couple years. It's an exciting time right now and the P1 is an IEM that can rock the boat a bit, even with its flaws.

A budget in-ear monitor (IEM) from China is nothing new. But how about a budget Chinese IEM with a planar magnetic driver inside? It’s the real thing with no gimmicks, and Tin HiFi proudly shows you the way to cost-effective aural bliss.

My college professor once said, a small error is a mistake, whereas a big one is a blunder. The name of my home state, Perak, was born out of a massive blunder. When it was first colonized, there was much activity in the mines, as they were rich with silver deposits. Hence, the area was named Perak, which means silver in the Malay language. It was only later that the precious metal was discovered to be tin, and everyone in the state gave a collective facepalm.

So it seems I am destined to review something from Tin HiFi to appease the tin gods, who are angry to this day. Let’s have it then. Formerly TIN Audio, Tin HiFi was established in 2010 in Zhongshan, China, to provide OEM solutions for audio. In 2017 they took a big leap and manufactured products of their own under the Tin HiFi brand, with the aim of providing high-quality audio at great prices.

They succeeded, to put it mildly. Their IEMs garnered quite some attention among the HeadFi community. Newbie threads like “BEST IEM UNDER $50 PLZ” will invariably have Tin HiFi products mentioned. Even here in Headphonesty, Tin HiFi stuff has been covered a few times. What cannot be ignored is how quickly Tin HiFi shot up to the stratosphere in such a short time, with T2 already attaining legend status.

Today we look at the new bullet in Tin HiFi’s chamber, the P1. Don’t let its unassuming name fool you, for what’s under the hood is extra special. The P1 encases a 10mm planar magnetic driver with a thickness of just 1 micron. Magnets on either side of this ultra-thin diaphragm produce strong magnetic fields to move the driver, theoretically with speedy-as-heck transient response times.

So what’s the big deal? Simply put, planar magnetic drivers are normally found in much more expensive, flagship-grade over-ear headphones, like the Audeze LCD series and HiFiMan, and they are notoriously hard to drive. There have been a few stabs at planar magnetic driver IEMs too, but at predictably higher asking prices, like the $599 Audeze iSine 20 or the $999 Unique Melody ME1. They are scarce, like the only guy in the block with a swimming pool, and are treated like novelty items.

Tin HiFi is one of the first companies to produce an easy-to-drive planar magnetic IEM for the budget-conscious, hoping to bring cutting-edge technology to the masses. The P1 retails for $169, but has a special introductory price of $149 at launch (20th June 2019). They are currently available via Linsoul and Drop (formerly Massdrop). Many thanks to Lillian of Linsoul for her swift communication and action in providing this review sample.

Packaging and Accessories

You’ve been wearing tees and jeans all your life and suddenly your crush asks you to go to a formal event with her. It’s time to dress up! Tin HiFi, so comfortable and securely nestled in the budget, $50-ish price range, knows he needs to dress for success this time around, to impress a whole new audience.

So dressed in a tux you go. The P1 comes in a handsome black cardboard sleeve with minimalist white lettering. The matte black box is quite large, with an inner lining made of felt which adds a touch of class. The P1 earpieces greet you in all its dazzling, lustrous glory. It’s an IEM you can’t wait to put your hands on, but hang on, there are other things in the box.

Also included in the accessory set is a beautiful (but small) faux leather case, a matching copper cable and an impressive set of ear tips. You get eight pairs of ear tips in total, which includes three pairs of wide-bore silicone in small, medium and large sizes; three pairs of narrow-bore silicone, and two pairs of foam tips in medium and large. It’s quite a complete set for on-the-go, although the case should really be bigger.

The website mentioned in the box doesn’t work lol.

Design and Build Quality

The P1 earpieces are made of food-grade 304 stainless steel, meaning they’re actually safe enough to be cutlery, for whatever reason you might want to go down that path. It doesn’t mean you can eat them. The earpieces are hand-polished and take on a mirror finish. They look professional and no-nonsense, like they came to kick ass and leave. Personally I’d prefer more colours, but I can’t fault the cool steel design.

304 is the most common type of stainless steel, and contains a bit of chromium (between 15-20%) and nickel (between 2-10.5%) as its constituents. 304 stainless steel is widely used in household and industrial applications such as food handling and processing equipment, screws and machinery parts. This is because it has excellent resistance to a wide range of atmospheric environments and corrosive media, and can easily be formed into various shapes.

As far as build quality goes, this isn’t your expensive, carved-from-a-single-block-of-metal type of construction. The P1 earpieces clearly have a front and back plate attached together to house the precious driver inside. But the food-grade stainless steel does denote good, reliable, lasting quality, no? How often do you have to replace your cutlery? So yeah, I’d say the build quality should be good.

All dressed up for the big McDonald’s date.


Rather than using the most generic of cables, Tin HiFi invested in a quality copper cable as stock. It’s a 4-wire hybrid cable made with strands of 5N oxygen-free copper (OFC) and an undisclosed copper alloy. The single-ended 3.5mm jack, Y-split and MMCX connectors look well-built, and there’s an audible, satisfying click when connecting to the P1.

Aesthetically though, I didn’t like it. The cable has a loose, uneven and slipshod braiding, giving me the impression that someone has been slacking. I thought FiiO’s LC-4.4C had loose braids, but this one takes the cake. Heck, it takes the whole bakery! The cable seems very likely to snag onto something and come undone, like how a thread gets caught in a tree branch and eventually the whole skirt is… well you get the picture.

Look, but don’t look. The uneven braiding is a sight for sore eyes.

Fit, Isolation and Comfort

As I write this the P1 is just released, so you only have larger-than-life press photos to look at. Don’t be fooled by them, the P1 is no larger than a marble, and conveys an excellent fit for my regular-sized ears. The nozzle length is quite long too, so you can choose a shallower fit or like me, push them in as far as they go because nothing calms me down better than a fully-sealed ear canal.

The stainless steel is lightweight, and when paired with foam tips, the comfort is supreme. They are just as comfortable with silicone tips too. No one has invented fabric-lined IEMs yet, so we’re nowhere near Slanket level when it comes to divine comfort. But for an all-metal build, this is as good as it gets.

With vents at the front and back of the earpieces, P1’s isolation is predictably below average. The planar magnetic driver needs air to move air, if that makes any sense. Engine hums, wind noise, the TV in the background, you’ll hear all that. If it’s any consolation to you, the iSine series and LCDi4 by Audeze are open designs with zero isolation. Best case scenario for the P1 is, with foam tips and deep insertion, I managed to isolate about 60% of outside noise.

If you squint you’ll see the vents. If you didn’t squint I haven’t done my job.

Sound Quality

Speed. Like the Keanu Reeves movie or the pep talk Lightning McQueen gives himself before the start of each race, speed is the essence here. The fast transient response of planar magnetic drivers, in general, are well-known, and practically advertise themselves. We’ve heard it on high-end headphones and high-end IEMs, but how about in a budget-priced IEM that looks dressed to kill?

Overall Sound Signature

The thing about planars is, even before you even assess the signature, your attention has been shifted to the overt transient speed of the P1. P1 sounds fast and snappy, allowing you to appreciate its detail and resolution levels too. You’ll also notice how roomy the P1 sounds. Not because the soundstage is huge, but rather how tidy it keeps the stage, aided by a stable, black background. Notes flit in and out briskly, leaving no mess behind. It’s great for neat freaks like me.

The P1 has a neutral signature, but one that won’t scare you off. It doesn’t go off the rails to extract every minute detail, but aims to preserve musicality as well. It’s a wholesome, enjoyable sound with slightly elevated midbass to provide some flesh and meat to the airy and euphoric treble. Maintaining a tight balance is the name of the game.

One thing you have to be wary of, the P1 won’t appeal to listeners looking for a warm, rich and lush experience. Emotion is a currency here. Notes are lean and sprightly, hitting in measured amounts and providing only what’s necessary. It’s like the scientific art of baking, where you need to follow every word of the recipe, or witness your cake collapse and die.

Ghetto blasting, slum slamming.

Listening Conditions

Critical listening was done after 50 hours of burn-in to loosen up the planar driver, but who knows? I do it more out of habit. The main rig was Sony’s NW-WM1A Walkman modded by Project K with the stock cable. The ear tips of choice were the medium-sized foam tips, inserted deep, which gave me the most balanced sound and best isolation. The silicone tips gave a sound signature that was too airy, coupled with an anaemic bass, but the experience might be different for you.

One thing I noticed was the P1 loves power. When driven by my cellphone, the detail levels were there but the bass lacked punch and authority. Even with the WM1A I drove the P1 on high gain, with volume levels between 60-80 out of a maximum 120 clicks. You might need a powerful audio player or an external amplifier for the P1 to sound its best.


Let’s go face-first and bass first. The P1 bass is like an expensive kiddie pool. It doesn’t go deep, but does great with what they have. I find the sub-bass reach lacking. It has a decent extension but doesn’t provide the visceral quality like good bass drivers can. So when I play my pimp-daddy tracks from The Weeknd and Bruno Mars, the urge to get down and dirty on the dancefloor doesn’t happen. It’s more like a lazy afternoon reading a book in the shade.

It gets better moving up to the midbass. The body and fullness of the midbass provides just enough warmth to satisfy when the bass drops. Note hits are round, with adequate punch and slam in attack, before fluttering away Taylor Swiftly and leaving a trail of wind.

It’s the flutter, or speed of the decay, that gets to me. The speed of the transients mean notes fade away like the wings of a hummingbird, with dollops of detail and easily-palpable texture. The bass has good warmth and resonance, yes, but is kept so tight, tidy and clean, it’s immaculate. You’ll have to raise your hygiene standards to keep up with the bass here, maybe with some aftershave and cologne.

What it lacks in colours it makes up for in vibrant personality.


Remember when buying a television wasn’t a crazy spec race, and all you needed to know was how large it was and whether it had colour? Those days are long gone thanks to high-definition TV. Today we have Full HD, 4K, and 8K televisions, which, when I’m watching WWE, enables me to focus onto the wrestlers’ sweat beads and body hair. Nice.

When it comes to high-definition in audio though, I’m all in, and P1 is as good as gold. Articulation is at its best here. From lower to upper mids, every ounce of detail from note attack to decay is captured, with emphasis on clarity, transparency and speed, glorious speed. The texture is so fine it’s like sand in your fingers.

It does come with caveats though. Vocals sound admittedly throaty, lacking the relaxing soulfulness of the human voice, and replaced with a sense of snappy urgency. Instrument timbre is skewed towards brightness, and notes tend to sound a bit thin. You’ll miss the warmth. But for all the misgivings in tone, the P1 mids are still technically proficient.

Sending monotone waves of marauding musical madness.


So the bass might be a bit light for some, while the mids might sound off-timbre, but when it comes to the treble, payday has arrived, baby. All the attributes inherent to planar drivers make their most brilliant impact in this region. With air as its friend and speed its second nature, P1’s treble is designed to thrill and enthrall.

This is the sonic equivalent of drinking a refreshing lime soda, atop a hill, with the cool breeze blowing at your hair. The extension is very good, with a lower treble peak to aid in clarity. Notes are crisp, well-layered, and attack as quick as lightning, leaving behind a waft of airy spaciousness after the decay.

What it accomplishes best is how much detail and texture is retrieved without sounding sibilant or grainy. While the notes begin with a crunch, a sense of immediacy, they end in a smooth, delicate way, like the aftertaste of a delightful cognac. This is the treble you’ve been waiting for, not just at $169, but at any price.

Sounds so good, you’ll eat ‘em. I know it doesn’t make any sense.

Soundstage and Imaging

You’ve been listening to Toto, and are suddenly overcome by the majestic imagery in your head of blessing the rains down in Africa. You get the impression that the plains of Africa must be a spectacular and vast place, although most of us will never make the actual visit, not even Totowhen they wrote the song lol.

P1 affords and divulges the thought as well, that the world is a big, curious place waiting to be explored. Being a vented IEM, the soundstage is generously wide and deep. Listening to Amber Rubarth’s Tundra, I swore I heard sounds a few feet from either ear. That’s Africa-wide, my friend. Also, Adele crept up behind me for a serenade, showcasing an impressive range in the Z-axis.

The height is not imposing though, coming up a bit short (pun intended), in a low-flying birds pecking at low-hanging fruit kind of way. Separation and imaging redeem the P1 somewhat, being adept at macro-imaging. The stage diffuses naturally with well-positioned cues from left to right and front to back. It’s deficient in the micro-imaging front though, you can’t pinpoint objects to its exact location.

Do they look like cunning, even evil eyes to you?


FiiO FH5

Notice the price jump. Now try to unthink it. I’m not pitting the P1 against higher-priced adversaries by intention, just that I don’t have anything in the $200 range right now. The FH5 is sort of my gatekeeper to good mid-fi, and the tyrant loves a good fight.

Right away the air and space of the P1 captures you. Music is rendered freely and more open, with a wider and deeper soundstage than the FH5. FH5 though, covers the technicalities well, and surpasses the P1 in imaging precision and stage height, giving a more fish-bowl like stage presentation than P1’s flat plains.

FH5 has a warmer and richer sound, with better body in the notes, especially in the bass. P1’s lighter bass feel like a child’s tiny jabs at an annoyed adult, but renders more speed and texture. The mids sound similar, both are airy and stonkingly detailed, but FH5 has the edge in realism and timbre.

Once we move to the treble though, P1 has a hearty laugh. It’s expertly-tuned upper end surpasses the FH5 in extension and excitement, and dares FH5 to go into the deeper end of the pool. FH5 plays it safe, sometimes too safe, preferring to give a smooth but robustly-detailed treble instead.

The P1 went against an adversary twice its price and lived to tell the tale. While no match for FH5’s imaging precision, bass quality and mids timbre, P1 holds its own very well in all the other departments, and turns heads fully aware that he’s the new hotness.

Fearless and transparent in all its undertakings. Naked too.

Fearless Audio S6Rui

I’m opening a present before Christmas, because I wanted to take my time with the S6Rui before unveiling it in a future review. However, given that S6Rui is also one of the darlings of Chi-Fi now, it’s good to be current. Again, this is futile, but try to ignore the S6Rui’s $389 asking price.

The S6Rui has a U-shaped tuning, with glittery treble and an incredible mud-stomping bass. Its presentation is full-bodied and forward, in contrast to the lighter and airier P1. Right off the bat the overt warmth and aggression of the S6Rui threatens to take proceedings over. The bass is thumpy and bloomy, but lord is it enjoyable to the last drop. P1 can only look on in awe.

The mids take a step back, providing some breathing space for the full-on sonic assault of the S6Rui. Here the P1 sounds clearer, more articulate and airier, but S6Rui delivers a smoother, more realistic mids timbre. Things come to a head in treble, with both nearly equal in extension and resolution. They manage thrill and excite, yet keep away from harshness. Both are stellar.

The S6Rui’s tuning is unquestionably better, but its main weakness is a tiny soundstage and congestion. Here the P1 has the edge over the S6Rui, proving superior in stage size and imaging capability. Overall S6Rui is the stronger IEM, but P1 takes proceedings down to the wire, proving to be the better value buy.

Barking up the right planar tree.

Final Words

It’s easy to dismiss the new kid doing new things. When I first heard of the P1 from Tin HiFi I reflexively thought “oh gosh, yet another gimmick”. Planar magnetic IEMs have so far been a hit-and-miss endeavour, so you’ll have to pardon my lack of enthusiasm at writing this.

But what Tin HiFi has accomplished with the P1 deserves some notice. They took a traditionally large, expensive and hard-to-drive planar magnetic driver, and shrunk it to fit inside a tiny IEM form factor. Not only that, they made it relatively easier to drive and slapped a very accessible price tag to it. Now everyone can planar. This understandably, has people rather excited.

The P1 has unassuming looks, like an old reliable, old-timey Oldsmobile. But as we’ve learnt all our lives, it’s what’s inside that counts. And P1, powered by its planar magnetic driver, provides a detailed, neutral signature that fits most genres. The sound won’t please everyone, but since planar magnetic IEMs are still at its infancy, we could be at the verge of something big. So do set aside your prejudices, and let the P1 take you to parts unknown.
The P1 looks identical to the Zodic Audio ET2202 from 2017
Great review. As an ety lover these look interesting tonally but that cable is a bit of a put off.
Very nicely written :)
Pros: Refined, balanced tune with a proper midrange - Build and comfort - Price for performance
Cons: Sub-bass could use a bit more emphasis - Foam insert fails to hold earpieces in during shipment - Cable could be better - Amping absolutely required

Today we’re checking out TinHiFi’s newest release, the P1.

Back in October of 2017, TinHiFi (previously known as TinAudio) quietly took over the budget scene with the T2. It was a dual-dynamic earphone and it’s combination of low price, outstanding build quality, and one of the closest things to neutral without being deathly boring won over a crowd infatuated with hybrids and flashy specs. Since then TinHiFi has released a number of products in the T1, T2 Pro, and T3, all of which were well received, some more than others. Their strong lineup of sub 100 USD earphones has kept them relevant, and to some, a leader in a very competitive segment.

The P1 is not only their first earphone over 100 USD, but also their first to move away from traditional dynamic and balanced armature driver tech. The P1 features a single 10mm planar magnetic driver per side. While that’s pretty cool, TinHiFi is not the first to bring planar tech to the earphone market, though I do suspect they’ll have been the most successful to date. Other brands have done it with varied levels of success, such as RHA with the CL2 and Toneking with the BL1. There are a handful of other examples out there if you take the time to hunt them down, all of which seem to have some critical flaw you either need to live with, or work around via EQ or some other method.

Let’s take a closer look at the P1 and why I think this is a standout product in the sub-200 USD market.



Thank you to Lillian with Linsoul Audio for arranging a sample of the P1 for the purposes of review. The thoughts here are my own subjective opinions based on time listening to the P1. They do not represent TinHiFi, Linsoul Audio, or any other entity. The P1 will be releasing on June 20th at an introductory price of 149.00 USD. MSRP will be 169.00 USD.



Edit 11/17/2019 - Reduced score to 4 stars. After using the P1 constantly over the last 5 months, the low end performance and reliance on amping compromises the user experience during portable use too much to warrant the previous score.

Personal Preference:

I listen primarily to various EDM sub-genres (liquid drum and bass, breakbeat, drumstep, etc.), hip hop, and classic rock. My preferences for earphone tuning are quite relaxed and as such their is no one signature I look for. The HiFiMAN RE800, Brainwavz B400, and Massdrop x MeeAudio Planamic are examples of earphones with wildly varied signatures that are enjoyable for different reasons. I generally listen at very low volumes, so keep this in mind when perusing my thoughts on how an earphone sounds.


Mobile: Shanling M0 or Zishan DSD paired with the Periodic Audio Nickel amp
@home: ZiShan DSD or Asus FX53V laptop plugged into a TEAC HA-501 desktop amp

While it’s sensitivity hints at it being a bit more power hungry than some earphones, it doesn’t tell the whole story. The P1 is a very hungry little earphone and requires a ton of power to get up to volume. Amping is absolutely necessary in my experience, unless you’ve got a stupidly powerful DAP available.

  • Driver: 10mm planar magnetic driver
  • Impedance: 20 ohms
  • Sensitivity: 96 +/- 3dB
  • Rated Power: 5mW
  • Max Power: 10mW
  • Frequency Response: 10Hz to 40kHz
  • Cable: 1.2m mixed braided (5N OFC and copper alloy) with MMCX

Packaging and Accessories:

TinHiFi did a great job with the P1’s packaging, providing an experience reminiscent of something you get from much more premium brands. The P1 arrives in a large matte black box with a matte black sheath covering it. The overall design is quite subtle with minimal branding and information printed on both the sheath and main packaging. Sliding the sheath off and opening the lid reminded me of the HiFiMAN RE2000 unboxing. While Tin’s packaging is plain cardboard vs. the faux leather of the RE2000’s box, it’s no less impressive. The lid is restricted in the amount it can open thanks to a black ribbon. The entirety of the interior of the package is lined with a smooth fabric, imprinted with the TinHiFi logo and website. The P1’s ear pieces and leatherette carrying case are set within a foam insert lined with the same smooth fabric lining the rest of the interior. Lifting out the insert you find a simple manual. In all you get:
  • P1 earphones
  • 1.2m mixed braided (5N OFC and copper alloy) with MMCX cable
  • Leatherette carrying case
  • Single flange, wide bore tips (s/m/l)
  • Single flange, medium bore tips (s/m/l)
  • Foam tips (s/m)
  • Velcro cable tie
Overall a decent kit. The tips are nothing special in terms of design or materials. I have plenty others like them and find they do a fine job. They’re durable and provide a reliable seal. The carrying case is quite nice and reminds me of the one Astrotec recently included with the Lyra Nature. It looks good, is spacious, and magnetically seals, though it’s not the most pocketable.

Lastly, I do have one issue and that is levied at the foam insert holding the ear pieces. Both on this P1 and a previous version received, the earphones were loose and rattling around inside the box when I first opened it. They sit too loosely in the foam insert and fall out with little movement. I can see this resulting in damaged or scratched products being delivered to customers and as such is something that should be rectified ASAP.

IMG_4369.JPG IMG_4370.JPG IMG_4376.JPG

Build, Comfort, and Isolation:

The P1 uses food-grade, hand-polished 305 stainless steel for the earpieces. Fit and finish is outstanding with the two sandwiched components that make up each side fitting together tightly and with minimal seams. Even the MMCX port out the top is integrated with minor seams. On the face of each earpiece is a unpolished triangular indent giving the design some contrast. It looks nice, but gives off the impression it was modelled after the face of a golf club. Perched in the pointiest end of the triangular depression is a pinhole vent. One more vent can be found near the laser etched L and R markers on the inner face of each earpiece, right near the bass of the nozzle. The nozzle itself protrudes at around a 45 degree angle and is slightly wider than what I consider average at around 5.5mm. A small lip is present just below the end of the nozzle and does a good job of holding tips in place. Lastly, the nozzle is protected by a stainless steel grill so you don’t have to worry about earwax or grime finding it’s way inside.

The mixed 5N OFC and copper alloy braided cable is a nice inclusion. The clear sheath puts the copper coloured wiring within on full display and is very flexible and memory resistant, though the exceptionally loose braid below the y-split speaks of cost cutting. It takes a fair bit less material to make a 1.2m cable with a loose braid than it does with a tight one. This is one of the reasons I prefer the T3’s cable, though in the P1’s favour each strand is a hint thicker. At least the rest of the hardware is quality stuff. The 3.5mm straight jack is nearly the same as that used on the T3’s cable with the silver carbon fibre look swapped out for black. The y-split is a simple metal cylinder filled with plastic within which the cable splits off into two twisted strands per side. Strain relief is unfortunately absent, though the bead-like chin cinch makes a return. It’s a bit smaller and less obvious this time around which I like. The MMCX plugs are again nearly identical to those used on the T3, though the knurling is a hint deeper, and the taper at the top a bit longer. Colour coding is present with red and clear plastic bands at the base of each plug denoting the right and left channels respectively. Lastly, preformed ear guides are present. I quite like the angle and how tightly they cling to the cable. I find loosely applied preformed guides occasionally make crinkling sounds when the cable bends, as experienced on the T3’s cable and some third party cables from HiFiHear.

When it comes to comfort, the P1 is outstanding. Sure, the steel housings have some heft to them but they are surprisingly small and free of sharp edges or unusual shapes that could cause hotspots or discomfort. The straight MMCX plugs also fit in well with the design pushing the cable up and around the ear at a natural angle keeping the cable from positioning itself in a way that rubs uncomfortably against your helix. While they will be a little cold on first touch if using them in chilly weather, I suspect that is about the only discomfort you’ll experience with the P1.

The P1 has very good isolation. Without music playing and a video playing in the background at my standard listening volume, not much beyond some muffled vocals gets through. The same can be said for use outside in the real world, like a noisy coffee shop. The P1 does an oddly good job of muffling high and low sounds, with cloudy vocals being about the only thing that cuts through.

IMG_4382.JPG IMG_4386.JPG IMG_4388.JPG


Tips: The P1 seems to be pretty tip sensitive. Wide bore tips (ex. Stock set, JVC, etc.) were not my favourite option as they reduced the already reasonably reserved sub-bass presence. Small bore tips, like Sony Hybrids, softened the treble a touch and brought up the mid-bass making the experience slightly warmer. Medium bore tips (ex. Stock set, RHA Dual Density, etc) were my preferred option. They provided a balanced sound with just enough sub-bass presence to satisfy while doing little to alter mid-bass or treble. Foam tips also sounded great with a presentation similar to small bore tips, but with added sub-bass.

TinHiFi does a great job of bringing neutral leaning signatures to the budget segment. Bass is well controlled but generally reserved. Mids are forward and clear. Treble is slightly (and in one case significantly) boosted to add excitement and energy. Sound stage is well spaced and airy. The P1 tweaks the TinHiFi formula resulting in their most balanced and accomplished earphone to date.

It wasn’t always like that though. A few short weeks ago a P1 arrived. While I was excited to put them through their paces, it didn’t take long to realize there was something off. Kinda how I felt about another planar earphone I reviewed back in November of last year. What was off? Upper midrange and lower treble. Everything was completely veiled resulting in a product that had the worst clarity in Tin’s existing lineup. Not good considering this was to be their new flagship.

Feedback was passed along to TinHiFi from a number of us lucky early reviewers, of which mine included the EQ settings I used to fix the midrange, and shortly thereafter news was passed back that the P1 was held off in favour of a quick retune. I suspected that wouldn’t be something TinHiFi could apply overnight, but only a week later a new P1 arrived. I cracked open the packaging expecting more of the same. Apparently TinHiFi can completely rework the sound of an earphone overnight because version two of this product is phenomenal.

I suspect this is a story TinHiFi wouldn’t want shared, but in my opinion it is one that needs to be told. Unlike some companies, they did not go ahead and release a flawed product then issue a silent revision later on down the road, or worse, leave it be. No, they listened to the feedback provided, made the necessary changes, and as a result all of their customers are getting a better product the first time around. So, major kudos to TinHiFi. Seriously. Okie dokie, onto how this thing actually sounds.

Treble is well extended without any significant roll off. For the most part brilliance and presence regions are fairly well balanced with the presence region seeing a mild hump. This results in an earphone that is quite detailed and clear, but not harsh and tiring. Some of the laser-like effects present in Tobacco’s “Berries That Burn” are quite sharp. Even at the relatively low volumes at which I typically listen (60-65dB, 80dB if I feel like “letting loose”), this song can be tiring. The P1’s treble is tuned just right to take off the edge without sacrificing clarity and detail. Decay is also quick. Not quite typical BA quick, but faster than all but the snappiest dual magnet dynamic based earphones I’ve used. This earphone has no issues with upper range congestion on tracks rich with treble.

The P1’s midrange went from it’s worst aspect to it’s best as a result of TinHiFi’s tuning adjustment. What was once horribly veiled and extremely disappointing is now crystal clear and completely coherent. Both male and female vocalists are well represented with female and softer male vocalists getting a little more love, as evidenced listening to Muse and Big Grams’ “Born to Shine” and “Run For Your Life”. Sarah’s vocals are a bit warmer and sweeter with a touch more body than what you hear from her male counterparts. Other instruments fare well, such as the heavy guitar riffs and high pitched guitar solo on Havok’s “Covering Fire”. That said, guitars could benefit from some additional attack and anger. Piano’s fare even better with a more natural weight and tone. This makes the opening of Muse’s “Exogenesis Symphony Part 2: Cross Pollination” an absolute joy.

Bass on the P1 is good but not amazing. While extension is there the sub-bass lacks emphasis. While there is some physicality to it, it’s less than I like. This leaves the somewhat punchy mid-bass region to carry the torch and while it does an admirable job, texture is also smoother than is preferred. As such, the grungy basslines oft used by Tobacco and The Prodigy lose some of the intended rawness. Speed is quick with the P1 handling the rapid bass present in a lot of metal songs, but it can’t quite match the rapidity of most armatures. It’s speed is alike that of the dual magnet drivers used by TFZ, but without the bass quantity or depth. Note that you can improve the sub-bass presence by blocking the inner vent, though the difference is fairly minimal.

When it comes to sound stage, the P1 doesn’t disappoint either. It doesn’t provide the cavernous experience of the old Havi B3 Pro I, but it’s far from intimate. Width and depth felt equally present to my ears and whether I was watching John Wick or wrecking fools (more like getting wrecked…) in World of Tanks, the P1 did a killer job of immersing me in the experience. A big part of this was it’s impressive channel to channel imaging which is precise and accurate, as well as it’s ability to provide very definitive layers to music and other audio tracks. Everything comes across quite organic and natural in the way depth is perceived. Separation is very good too, though I prefer how it is handled by some of the better multi-driver earphones I’ve used.

Select Comparisons (volume matched using Dayton iMM-6):

TinHiFi T3 (69.99 USD): The T3 has a brighter, more aggressive presentation with more heavily emphasized upper and lower treble. The T3’s armature pumps out a little more detail at the expense of control with cymbal strikes coming across less well defined. The T3’s mid-range is similarly emphasized but lacks weight and body in the vocals that are present in the P1. This gives the T3’s mids more air and space, but it sounds less natural with vocals. I prefer the T3’s leaner presentation with guitars though. They have a more aggressive edge which is lacking on the P1 making it less suitable for metal and rock genres when compared to the T3. The P1’s tonality and timbre are more accurate otherwise. Bass on the P1 has a heavier feel and greater emphasis. Mid-bass is more prominent aiding in the overall warmer tone it has when compared to the T3. Texture and speed comes across as superior on the T3. While sub-bass extension is similar the T3 provides a slightly more visceral experience. Sound stage on both is quite good though the P1 is clearly superior. The P1’s default listening position sets the listener slightly further from the performance. The P1 can toss effects further away, and with a greater and more accurate sense of depth and movement. This also helps with it’s layering which is outstanding. Separation is also above average, though I’m giving the T3 the nod thanks to it’s leaner presentation which keep notes even more defined.

The T3 and P1 are both exceptionally well built. I’ll give the edge to the T3 though. The design is more complicated and interesting, with fit and finish that is no less impressive. TinHiFi knows how to put together a quality product. The bleeds over to the cable too. As noted earlier, I prefer the T3’s cable. The tighter braid and extra material combined with similar hardware makes it feel a bit more premium in my opinion. That said, the P1 cable’s copper colouring looks better than the white and gold of the T3’s cable.

Overall I’m torn on which I prefer. Pitting the T3 against the P1 just shows off how good it is, but it also comes across more analytic and worse off as an all-rounder. The P1 is nicer to listen to for longer periods, feels more versatile, and while it isn’t better in every way which might disappoint some, the final package gives off a greater sense of completeness and tuning maturity.

BGVP DMS (159.00 USD): The DMS has a similar level of treble emphasis as the P1, though without the same expert balance. While fairly even, it eschews some upper treble emphasis for added lower. This gives it a drier tonality that drops some of the pleasing sparkle present in the P1. The DMS’ midrange also takes on a less organic tone, and with a touch less weight to vocals and instruments, though timbre is near equally good. Clarity and detail are also quite similar with the P1 having a very slight edge. Not sure which presentation I prefer. Bass is where the two really separate. The DMS is notably bassier with additional mid-bass and sub-bass. Mid-bass is punchier and sub-bass extends deeper and with a much more visceral feel. Texture is similarly satisfying on both. Could be better, could be much worse. Speed seems about similar with the DMS’s dynamic driver having a longer decay time. Sound stage on both is excellent with the DMS coming across slightly more confined thanks to it’s more intimate default position of the listener. Imaging is tighter and more accurate on the P1 though the the DMS rivals it pretty easily in layering and betters the P1 in separation.

Like the P1, the DMS has a metal shell. Unlike the P1, the DMS’ shell is aluminum. It has tight seams too, but you can see lines from the machining whereas all that is smoothed over on the P1. The P1’s build feels more polished (no pun intended), whereas the DMS’ is unquestionably more interesting thanks to all the curves and prominent vents. I have a soft spot for the DMS’ cable given the old school flavour, but I can’t deny the P1’s more premium materials and design.

Due to the differences in the low end, these two satisfy different crowds. When I want the technical competence with some extra low end grunt, the P1 cannot satisfy the same way the DMS does, even with the vent mod. But, if I want that lighter bass response and overall tuning balance, the DMS cannot do what the P1 can without busting out the EQ. After directly comparing the two, I lean towards the DMS due to my preferences for electronic music. However, I know could go either way depending on my mood. They’re both head of the class imo.

Shozy & Neo CP (165.00 USD): Despite their vastly different driver tech, the CP and P1 are tuned quite similarly. Treble on both is similarly emphasized and balanced but I find the CP smoother and better controlled. The CP’s midrange is a touch thicker, warmer, and not quite as forward. Clarity is slightly worse out of the CP’s armatures while matching the P1 in terms of timbre and tonality. Neither has game changing bass but I find the P1’s more satisfying. The CP has a mid-bass focus and rolls off in the sub-bass earlier. While notes have a bit more punch through the CP, deep notes are mostly lost and lack the visceral rumble of the P1, however tame it still is through that earphone. Sound stage is larger on the P1 which has a wider, deeper presentation. Imaging is equally impressive on both. While the P1 is a hint more layered, the CP takes the freshly baked separation cake home with it.

The CP and P1 couldn’t be more different in build and materials; steel vs. acrylic. Both are great examples in their respective fields, but the CP does what it does better. There are few earphones that can match the perfection of the CP’s construction, both inside and out. It’s cable is nicer too. While the MMCX plugs look to have been provided by the same source, and maybe the straight jack too, the y-split is thicker and more ornate. The wiring itself is about the same gauge but is more tightly wound (but still loose) and more flexible.

Once again, choosing between these earphones is a harrowing experience. They’re both wicked good. The CP is a little smoother and more intimate with technical capabilities that are just as good. The P1 is larger and more open sounding with a more satisfying low end, but isn’t quite as refined sounding. I think the P1’s more spacious presentation and low end extension would win me over in the long run though.

Final Thoughts:

The P1 provides a very premium experience for not a lot of money. From the gorgeous packaging with it’s classy presentation and soft touch interior, to the top of the line build, to the balanced sound signature that does everything at the very least well, the P1 shows itself to be a fantastic all-round package free of any significant flaws. As a result of the consistency in positive experiences, the P1 is a top tier pick in it’s price range.

Are there improvements I would make? Sure, though none to the sound (well, sub-bass presence could be bumped up a bit) since the final product ended up remarkably similar to what the original sounded like with EQing in place to address the issues. I would like to see TinHiFI revise the packaging to better hold the ear pieces in place. Nothing is worse than getting a damaged product, even if it is something as simple as a small scratch or mark. I would also like to see a cable with a tighter braid. The existing cable is fine and better than most, but the cheaper T3 has an arguably nicer cable in my opinion. If they could make it more sensitive without hindering performance, that might be a worthwhile change too. The P1 is currently a very challenging to drive earphone. Cell phone users and those with basic DAPS won’t get much out of the P1 without an amp.

Thanks for reading!

I've had them for 2 days now, and the more I listen to them the more I like them. I would describe them as full, balanced, rich detailed and nuanced. I just fired up Derek Trucks Band - Song lines Album and I'm hearing things I've never heard from my Shures and the Bass has come alive. WOW. Give them time and listen to multiple genres and you'll be rewarded.
I have P1 for a while. Not sure where to place them. I enjoy them more and more. All is controlled and punchy..
I run P1 perfectly well with LG V20 in high impedance mode (triggering it with the 75 ohm jack and L male to female 3.5mm adapter) plus I use a bit of bass boost and virtualization (with the app). It sounds absolutely amazing - also way more natural and analogue like than any IEM I have (KZ ZSX, ZS10, ZS10pro, AS10, ZS3, ZSR, TIN T2, TIN T4, Shuoer Tape. I also run P1's with fiio k3 balanced and at home with additional amp (Bravo audio) and there isn't much difference.
