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.

Tin HiFi P1

“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.”

  • Subbass extension
  • Might be bass-light for some
  • Mids timbre and body
  • Average imaging capability

Whirlwind Revolution

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.

The Planar Plan

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.

Tiny Trinkets

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.

Steely Nerves

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.

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.

On A Diet

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.
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.
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.

Sweat it Out

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.
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.

Dirty Pop

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.
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 Toto when 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.

Axes of Fidelity

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?
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.

Intonation Recreation

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 Bravery

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.

Viva la Vida

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.

  1. Not since Stan Cornyn and Lester Bangs have I read such a brilliantly sculpted review!
    The finest music reviewer historically was probably George Bernard Shaw; with immaculate, sleek, artful prose and wit.
    You, Sir, are in that good company!
    Please keep up the excellent high-standards and enjoy your literary life. I know I surely do.

  2. Great review! I am not sure if I will order them or not. I have already so many IEM,s and Over ears. By the way: I Love Malaysia!!! I was in different parts for pretty long Time. In KL, Penang, Langkawi, KK, Bintulu, KB. There are many good places in this World, especially in South East Asia, but I am planning to make Malaysia my second Home in the Future! THX!

      1. Well, that could be. But I am sure therefore you know Ipoh very well lol! Greetings from Vienna! We had yesterday about the same Temperatures like in your Country over 36 Celsius.

        1. Same haha. Crazy warm weather we’re having. Hope you’re doing well over there! Would love to visit Austria.

    1. This review was such an enjoyable read! Your descriptions are rather vivid and has helped me imagine what the good and bad points of the P1 are.

      Suffice to say I’m really looking forward to these headphones. Will be interesting to compare it with my akg over ears and the isine10.

      I’ve ordered the P1 already, but after reading your review I feel like ordering it again 🙂

      1. Could you please compare it to Astel and Kern Billie Jean. I recently bought the Billie, but after reading your such an insightful, blistering review, I’m having second thoughts.

  3. My brother, i missed having breakfast in Ipoh.

    Superbly written review. Heck, I dont even notice how freaking long it was.

      1. It is true that the P1 need more power (and bass). They work well with a FiiO Q5, or even with a Radsone EarStudio ES100 (both in Bluetooth mode). The Fii0 Q5 has a bass boost switch as well as a switch for more gain. And the Radsone can be run with a free Radsone app that allows you to use EQ – also on streams from Spotify, Tidal or whatever. So you can shape the bass to your heart’s content. 🙂

    1. As a possibly better option than the P1 (which I love with boosted bass and more gain), you might want to check out the Shuoer Tape reviewed by Bad Guy Good Audio Reviews. He even compared it with the P1 here: The Tape apparently doesn‘t need boosted bass or a lot of gain to sound great, but does offer a lot of the transparent detail of the P1.

      1. That,s what BGGR says! It can be accurate or not. I am overall really Disappointed with the P1 and find them even Overpriced. 3Stars from me!

        1. Especially the Sondstage and the Imaging are both very poor! Build Quality is also not good! I guess they got some Quality Control Issues because of the Hype!!!

  4. Such a beautifully worded review! Not only highly informative, but also highly enjoyable from a literary point of view. Sweet!
    Now about the P1: Got mine today (at the same time as the killer Audiosense T800 arrived – audiophile heaven on a budget!). As for the P1, it is every bit what you say it is…when driven sufficiently and with a bit of EQ. I‘m running it – as with all my IEMs (among which are the DM6, the Tin Audio T2 pro, the Kanas Moondrop, etc.) – off a FiiO Q5 (not the latest model with the „s“) via high-quality Bluetooth, using a high-grade Linsoul silver-plated copper cable. With that set-up, it works best when the EQ gain switch of the FiiO Q5 is on, and – depending on the music you‘re listening to or your taste – also with the bass boost switch on. However, I have to admit this set-up underwhelms me. Why? The bass boost gives the P1 some balls, but also muddies up (masks) the mids and trebles somewhat. So not cutting it for me. With the Q5, I‘d stick with the Audiosense T800 for sure, and skip the P1.
    Next set-up (brilliant!): The cheap-but-mighty Radsone EarStudio ES100 also running via Bluetooth, AND using the free EarStudio app with EQ (!) adding a bit of bass and even a bit of upper-mid and treble. Folks, this is a high-res music streamer‘s dream set-up…at least if you‘re not up to buying the Audiosense T800 (which is admittedly more than twice the price). The EarStudio app allows you tweak the EQ of the P1 in a beautiful way. OK, so the Radsone isn‘t as hi-fi as the FiiO Q5, but paired with the pristine and impulsive P1 you are bound to have some eargasms. And the Radsone weighs next to nothing, runs long on a charge, clips to your shirt or pants pocket and lets you enjoy, unfettered, blissful Bluetooth streaming (of locally stored Qobuz files in CD or high-res quality, or Spotify files of max. MP3 quality). TIp: The EarStudio app lets you store up to 4 custom EQ settings, one for each of your favorite IEMs. And specifically for the gain-hungry P1, you can push up the overall gain in the EQ stage to get sufficient volume out of the P1. This is a quick-and-dirty combo that really works, and lets you tweak the P1 to taste, making the most out of its sonic supremacy while compensating for its (small) weaknesses. Strange that this solutions works better than pairing the P1 with the far more hi-fi (and expensive) FiiO Q5, but the proof is in the pudding, eh? One gripe remains for me: I am still struggling to get the P1 to seal sufficiently and reliably. I hate foam tips, and the supplied silicone ones aren‘t cutting it for me. I think I‘d benefit from some silicone tips with a bit of a longer „neck“ to them, in a medium to fat width for the outer seal. Any ideas?

    1. Thanks for the informative post! Makes me want to try the Audiosense.

      As for the fit, Spinfit double flanges (or any other double-flanged silicon tips for that matter) might do the trick if you want a longer stem.

  5. I haven’t had a respectable laugh reading a review in a long time…an yet, yes, you are quick and funny. Kudos my friend!

  6. Hi Lau, I loved your vivid review and your impressions of the p1 were quite similar to what I felt. Instead of banging on about how your tech review makes me want to eat a cake, I found a way to make the p1 sound like ear sex.

    I felt compelled to write to you.

    I’ve had this thing called BOOMSTICK by BOOMCLOUD360 for a while now. Its like an amp, but it also pushes instrument separation, while improving treble, mids and bass quality, making everything sound much clearer and positional. There are 3 settings but at its most potent, it feels overpowering, like a fat lady in a tutu about to burst at its seams. But because the P1 has such control, I am able to use it at the highest setting which gives it much needed emotion. Some described the amp as “audio sorcery” and it was widely lauded in the tech circle when it was introduced. Unlike the Creative SFXI with gives 3D positioning at the cost of fidelity (so I’ve heard), the Boomstick just improves music like magic, giving it alot of airiness and presence. Unfortunately I think it has been discontinued but maybe you can find it on ebay. I got mine at usd10 when it was clearing stock.

    The P1 + BOOMSTICK sounds majestic from my macbook pro with Vox and Boom 3D, like I was in a soundproof studio with expensive speakers, but from my Sony phone it was still kinda lacking. So I got myself the EarStudio ES100. The Boomstick has algorithms to improve sound, but it lacks power.

    On the ES100, the P1 sounded loud, but tinny, and instruments were not separated as much as I liked. I thought it was rubbish. It was still lacking emotion, even with balanced cable. The Boomstick alone was a better solution, but it didn’t have as much power as I’d like from a phone setup. The P1 is like a glutton with tapeworm!

    So I added the Boomstick to the ES100, but it was STILL RUBBISH! After ages of tweaking, I realised I had to pull down the bass, letting the mids and high shine a little and suddenly I am seeing tons of audio images in my little private heaven. The P1 finally had technical superiority, AND ALOT OF EMOTION!

    Summary: Boomstick on Max, ES100, and reduce bass response. (the boomstick bass seems more reliable because it doesn’t “stick” to the other frequencies” like the ES100’s bass or the one from my Sony. I have a feeling those equalisers bleed into the mids abit too much)

    Boomstick really gives everything much more emotion. I don’t know why they failed to take on the market. I stick my boomstick to the final loop of any setup I use.

    Btw, I am Malaysian too, but half japanese. I work in documentary and films, and sometimes in a studio with great speakers and sound engineers from juliard. Being a cheapo, I don’t personally have many awesome audio gears, but have a discerning ear and emotion is my day job. Thanks for the review it was an awesome read. MALAYSIA BOLEH and I LOVE IPOH!

    1. Great tips here, thanks for sharing. I’ve got the P1 with a Hidizs AP80 Pro as a source and, when plugged to the 2.5mm balanced output, they sound great to me. I will definitely look for the Boomstick, though – you got me curious there. Regards from Galicia (Spain) – Avelino

      1. Hi Avelino,

        It’s kinda an unrelated reply, but I am now using a Sony NW-ZX507 with Boomstick + Venture Electronic’s Monk Lite earbuds (120ohms) and its more enjoyable than the P1. The sony gives the music a warm, lush tone; the Boomstick makes everything airy and spacious and the VE Monk further rounds up each instrument at the high frequency to give it a strike and energy that makes the sound really dynamic and non-fatiguing. That last part I cannot effectively express. The broomstick and VE monk doesn’t cost much, but it makes every setup sound much better than it should.

  7. Do you guys think they would work well with the lg smartphone lg g7 thinq? Ive heard that its good with audio.

    1. Hi Axel,

      I doubt it. I am using it with a dedicated walkman (NW-ZX507) and the P1 sounds great with it, but it still feels somewhat hampered. I think this is a very power hungry IEM for it to be driven to its fullest potential (my wife has a LG smartphone I think it was the G6)

  8. Brilliant review – both informative and delivered with heaps of prowess and gusto on the writing front. Recently got the P1 and like them very much when paired with my AP80 Pro (balanced output). Didn’t fiddle with EQ yet, but probably will.

  9. Got my pair of Tin HiFi P1 today and what I can say: they indeed need a lot of power for high volumes. Probably compareable to a Fostex T50rp headphone.

    I’m running them on an Earstudio ES100 at the moment. Let me add, that all my files are replaygained, which reduces volume by ~6-10 dB(A) on modern rock/pop albums.
    The ES100 is just enough to drive them to loud volume. It is rated at 1.1 Vrms @ 16 Ohm (unbalanced), which means ~75 mW @ 16 Ohm.
    I probably should try the balanced output of the ES100 with 2.2 Vrms (300 mW) @ 16 Ohm, which means +6 dB compared to the unbalanced one.

    After listening to them I can say: They indeed sound great. BUT the bass is much less for me (and I’m no basshead). I have to use the ES100 equalizer and increase bass level (60 Hz and below) by about 4-6 dB to be happy. That matches the amount of bass, that a good speaker produce in a living room. Or the bass that my Denon D5200 headphones have.

    P.S.: Also got a pair of Mackie MP-240 IEMs today. I’ve read a lot of reviews that praise their linear sound with a bit emphasisis on bass. Well, they are wrong. These ones have to much bass. To get the same bass amount from the P1 you need to add at least 12-15 dB with the EQ.
