Knowledge Zenith (KZ) PR1 HiFi

Knowledge Zenith (KZ) PR1 HiFi​

The PR1 comes in three flavors at the moment, the regular PR1 which has a resin shell and aluminum faceplate, the PR1 HIFI, which comes as a resin/electroplated build and aluminum faceplate, and the KZ PR1 Pro. All have 13.2 Planar Drivers. The Pro version comes with a resin build along with an aluminum faceplate.

With that out of the way I’m going to be doing fast and simple comparisons between two other recent KZ creations and comparisons between two other Planar IEMs. Note the Zeitan Wu not pictured here.

Listed in order of best to worse
A) KZ ZS10 PRO X
B) KZ AS16 PRO
C) Kinera Celest Gumiho
D) KZ PR1 HIFI

Note:
The Zetian Wu was not really in test group due to price constraints, though it's only an important comparison as another planar, to make sure I wasn't just judging the KZ PR1 HIFI's incompetence solely on planar attributes.

My rating for the PR1 HIFI is the lowest in this test group, and I will explain my. While not a bad IEM in any form or fashion…….the competition is stiff. Meaning nothing is wrong per say about the PR1 HIFI, except it lacks separation of elements in the stage. Everything else is great, and you may still be interested in the PR1 HIFI due to the great build, wonderful fit…….and of course value. As truly with the Kinera Celest Gumiho not being a true planar, with different style of Planar construction and a BA added, it’s different.

1) https://www.head-fi.org/showcase/the-new-kz-zs10-pro-x-universal-iem.26128/reviews#review-29430

The KZ ZS10 PRO X is the overall winner here. Reason being it shows a nice instrument separation, in contrast to the clogged togetherness of the PR1. Also for many other reasons it even beats out second place in our contest. This list of reasons is gone over in the review. Though a short take is that it has a slightly more (natural) laidback treble, and a more natural bass, being DD as oppose to BA bass. 5 stars!

2) https://www.head-fi.org/showcase/knowledge-zenith-kz-as16-pro.25953/reviews#review-28967

Here is KZ AS16 PRO climbs to second place despite it’s slightly controversial nature, being it's impedance dependence for tone. I personally found it charming and filled with incredible abilities. With 8 BA drivers per side, offering a slightly buzzy yet airy and thrilling take on my music library. 5 stars!

3) https://www.head-fi.org/showcase/celest-gumiho.26076/reviews#review-29411

The Kinera Celest Gumiho makes third place simply by reason of pure bang-for-the-buck………..big sound for the buck…..and really doing nothing wrong. While not perfect, its one issue is the slight BA sheen put-out by the addition of the BA to the 10mm planar driver. Still the little Gumiho has pizzaz and soul. Rocking its way into third place simply because it’s just so darn fun to listen to. In fact, I haven’t heard the KZ PRI Pro yet, but if KZ wanted to stay competitive, they would need to make the KZ PR1 Pro have the little Gumiho’s separation and clarity to still be competitive.The Gumiho got a wonderful 4.5 star review.

So that’s our four IEMs listed in the photograph.

One more……….
I got to thinking…..you know planar IEMs have a sound, a character all their own, thus popular right now………but what if I am simply judging these IEMs only with comparison on separation. With just me liking (and focusing on) separation? What I’m referring to is 1st place is a Hybrid, second place is 8 BAs, third place is also a Hybrid of a 10mm planar and a BA. So what if these judgments are purely subjective and I’m in my own little world here, not offering and value of opinion to anyone. Judging simply due to personal (read subjective) preference? So regardless of price, I threw the Tangzu ZETIAN WU into the mix.

That’s right, our KZ PR1 HIFI is totally half the price of the ZETIAN WU! So why am I comparing them here? Because of planar separation. That’s right, it’s not just a character of planar technology to have the soundstage elements seemingly near one another.

Is there a huge difference between the separation going on with the Zetian Wu and the KZ PR1 HIFI?


Does a bear schiit in the woods?

In fact........again the separation issues with sound elements become really the main reason for the KZ PR1 HIFI being at the very bottom of our list today……………still it’s an enjoyable IEM.

Knollage Zenith has been on a roll lately and proving their Knollage is real……being the fit and form-factor of the PR1 rocks! It offers great sound occlusion, feels lightweight and has a great nozzle lip. The nozzle itself combined with the overall shape is totally correct. Look at the photographs of the KZ PR1 HIFI! Just look at the work of art you get. In fact due to its shape a wide range of tips can be chosen. This is often what happens with a great shape, we are able to keep getting perfect fit with a whole range of ear-tip options. I ended with the shallow profile/wide-bore as the ultimate methodology to get soundstage. So my soundstage was about average, to slightly better than average. Still there is actually a very close relationship between the three KZs talked about in this review. Offering a subtle V fun response with all the bases covered. While it could almost be said that the sound character difference was arrived at by the use of different sound making technologies? Each way to make music has its own driver idiosyncrasies.

That’s right KZ did the multi-BA, they did the Hybrid, then they made 3…..count-em 3 planars. So? Did this third KZ planar come-out (fast) due to KZ attempting to make their mistakes “fixed” or are they simply playing us? You know PRO, PRO X, HIFI PRO, HIFI PRO X............and so on? I haven’t heard the Pro model yet……..and with so many products launched/produced it simply adds to the confusion.

13.2mm Dual-Cavity Planar Magnetic Driver Earphones

• Ultra-thin Silver-plated Diaphragm
• N55 Double-sided Magnetic Circuit
• Exquisite Finish With Aluminum Alloy Face Covers
• Professional Tuning Adjustments For Impressive Sound
• High-Quality OFC Silver-Plated Cable

Joining the pack, KZ is attempting to cash-in of the absolute flood of planar popularity. And just look how they tried to one-up-man-ship the whole design. Those exhaust vents……..IEMs become more like cars in design every year. Seriously how many IEMs do you know which have vents on both the front and the sides?


Build:
The PR1 comes in a solid three piece electroplated shell. The bottom (ear-facing) semi-custom build offers a single small vent, in contrast to the 9 slots sporting the top-plate, and 5 vents off to the side, as shown in photographs. I don’t think build is solid aluminum? The faceplate is 100% aluminum, but note the back is referenced as electroplated, and strangely it almost feels like metal due to the metal top finish. Cruising in at only 6 grams a piece, they can’t possibly be all metal………right? It’s a strange future world where KZ now offers electroplated plastic!

The nozzle goes all out to hold ear-tips on with style. Already touched-on, these nozzles are not only angled the correct way, and have the right length, they offer beautiful beveled lips and inset screens to-boot. An extruded two-pin acts as the only clear plastic seen in construction, seemingly emitted through a small (doorway) port on the aluminum faceplate! This qdc style of .078 2 pin goes to offer increased strength due to having the outside plug receptor actually add another layer of material (plastic) in daily use. Such apparatus also guarantees an absolute angle of attachment (causing you the cable fitter) to approach the pin-set-up at only an exact angle, before reception will occur. Once joined the beginning of the cable ear-hook is started by the plastic 2 pin holder. An OFC silver-plated surface wire adds to the frequency balance at hand before being quickly changed out for possibly better cables you may have on hand. Not that there is much wrong with the provided cable………it actually works fine……….it’s just a 4.4 balanced add becomes effective…………..especially when you get down-and-dirty and release how darn hard the PR1 is to drive.

This 13.2 Planar driver is difficult to drive. I mean all planar IEMs like juice, but you will be reminded fast, especially if you’re doing as many side-by-sides as I was during this review. Oh…….that’s right…….when your doing comparisons the all BA is incredibly efficient, the Hybrid KZ in the middle (as far as power requirements) and the planar IEMs the most difficult to drive.

IEM shape:
Yep…….I made a section just to reiterate on the shape! If all IEMs could only emulate this exact form……the world would be a better place. Seemingly just right……..is what Goldilocks found, you see she found balance, and balance is what is taking place here………as far as form and weight, nozzle length and angle. The other guys can simply 3D scan this IEM and replicate much of what’s going on…………….the special trait is feel too. As the electroplated plastic has both the feeling of metal and plastic, it doesn’t get cold and seems to carry the perfect middle weight. And……with all the vents you would think natural sound occlusion would be awful…..but no, it’s blocked-off by the internal driver by being a double cavity inside. Your fingers touch the very edge of the aluminum faceplate during the first adjustments and they fit so beautifully……..you then can leave them alone…….paradise!

Packaging:
Laughably the charm is again they didn’t waist paper on QC documentation, and placed a rubber stamp marking on the bottom of the box……….proof the QC person was present to inspect this IEM upon leaving the factory floor! YZ did the inspection duty on 10/15/22 using a hand stamp. While the packaging in not anything other than a box, you have to realize that I have witnessed lower quality IEMs with GUCCI packaging…….that made you question where there priorities were. Where here the effort goes into the sound and build of the product……..with generating 1/2 million examples of certain models……….you come to realize KZ is at the point now of going from strength to even greater strength! Truly I like the package……..I mean put your money where it’s important…….at this level of IEM……we care about sound and consistency of build; give us those two things and we will be happy-campers.

Sound:
Bass:
Probably the bass is what changed the most upon burn-in. What was a thick syrupy sludge of bass OTB, became a reserved and critically controlled spectacle. This is surprising and found as an opposite in bass response in contrast with other planar IEMs. That’s right, most planar IEMs (and this is my 7th) have started-out a bass shy experience, only for the burned-in mature bass to finally show-up at 60 to 100 hours. While here was are witnessing 7 days of full burn-in…………..the bass was definitely “fixed”. In fact it went to the total other-end of the spectrum. While still showcasing the celebrated current KZ sound……….we are now in view of a controlled, reserved and relatively fast bass response. Somehow smoothness was also the 2nd best change. Where smoothness and cohesiveness was obtained, it’s the bass that became noticeably different, more agile, better paced and in the end obtained imaging to die for. Though to be critical, the stage still shows average styles of separated imaging resulting in average clarity. And even with this new reserved stance in bass placement……..stuff is slightly jumbled-up and centered, instead of gloriously taking a fully entertaining disjointed spender in staging. I know I may sound like a broken record, going over the same issues as when this review started, but it is what it is. I mean it’s OK, nothing totally bad or anything……..it’s just not a class leading experience and not of a true value do to these issues.

Treble:
While yes, there is this planar sound, it’s developed to introduce great transients and they are clean and fast. There is a slight upper timbre issue which goes to make instruments sound ever-so-slighly higher in pitch than they truly are. It’s this ever-so-slight plasticky tone that while not so bad, is not so good either? Everything falls under this blanket of reproduced tone. Yet attacks are clean, and decays offer a great pace and clarity. The basic agility is maybe going to be the singular draw in the market-place……..that and the look and feel of these simply in your ears. This takes place with every amp I’ve tried and every cable. Doesn’t matter which ear-tip change I do either, this tone is just part of the PR1 experience though and though. What your getting for your dollar is quick and clear transients and nice pace and fast decays…………really sounding more on the digital side of sound personality, than the analogue. Still all this is fun and in a way cutting edge for the price-bracket. Especially if you have a fast rock song, where every instrument get some attention………..and the more and more you listen you kinda become under the PR1’s spell, seemingly starting to forget about the issues………almost. So it does have that?

Midrange:
It’s the midrange, the mids are what you buy the PR1 for. And crazy as it sounds these didn’t come-off sounding this way out of the box. We went from the subtle V giving way less emphasis to the midrange, almost buried in the mix……….to a celebration of midrange as the KZ PR1’s final destination. While still stuffy in character, vocals start to work their way out, and while not offering the most inner detail or even showcasing…….there comes about a utilitarian character. Just getting there, while being separated from the whole mix, still not fully human sounding. It’s this lack of relief in the mix that will have you try plain vocal music……..and again even when there is nothing around to complete with, vocals are still shown for great articulation but lacking texture………almost simply going through the motions. It’s this texture we are looking for, for involvement to take place. Guitars are exactly like vocals…….in every way both styles of sounds follow the same character issues here. Where yes, pace and bounce in there, yet this is a sterile environment missing that all important factor called simply…………life!





Conclusion:
While relatively fun and comfortable, some life essence seems to be left out. In a way I feel that it’s gone, yet at times I can’t exactly put my finger as to why it’s gone. Is it the detail texture? Is it the slightly skewed-tone? Because to pace is great, better than great, the pace is simply amazing……these just need some adjustments. Maybe that’s what the KZ PR1 Pro brings to the table, I don’t know? And……for me this is sad to find, as the KZ ZS10 PRO X is one of my favorites of the year. Really I’m 100% on board as to what the ZS10 PRO is doing, 100% of the time! You may have called me a Knollage Zenith fan back in 2016 when the first wave of popularity hit and my review was spotted on the front page of Head-Fi. And years went by, and I paid very little attention to what KZ did. I hadn’t forgotten about them, but I had no idea how far they had come with sound design and making budget IEMs capable of providing amazing sound. Meaning I actually found it pretty much unbelievable how good the 8BA a side KZ AS16 PRO is. Then they top-themselves again making the Hybrid 5 driver KZ ZS10 PRO X! So you can totally see I was excited to see how they would try and incorporate planar technology into their offerings. And in my testing here I had to rotate in a second planar IEM into the test group side-by-sides…….to use it as an extra example of planar technology…….to see if I wasn’t just making all this up. So in conclusion, and after thorough testing the KZ PR1 HIFI finds its place in the lineup, not really a bad IEM, but not really the best style either. Though this testing example I have tried to be complete and fair, I have given the KZ PR1 HIFI enough burn-in as well as ample chances to prove its worth, I have used multiple music genres and multiple amplifiers, I have tried multiple cables and multiple ear-tips too. And while the build and fitment of the PR1 HIFI is great, and singularly one of the best ever…….there is more to an IEM…..and that more takes supreme importance in sound quality. We all have our favorites of the IEM stable which don’t always fit fantastic, but sound wonderful, you know which ones I’m talking about. KZ is close on this one……I hope to see the company join the success stories of other planar manufactures, embracing this now popular form of driver technology, as it seems they got halfway there with the PR1 HIFI……..just not all the way.

The KZ PR1 have been sent to me by Linsoul for me to try and share my opinions. As always with Linsoul, they have not made any specific requests and my review will aim to be as unbiased and sincere as possible, although you should always consider the fact that these IEMs have been sent free of charge.

Keeping up with my usual aim to not publish purchasing links on forums where I am only a guest, even if all my links are non-affiliate, you can find the PR1 via Linsoul by visiting the version of this review published on my blog (link at the end of this review).



Intro…

Until recently there were very few planar IEMs on the market, we had Audeze, Tin and not much more. Now there are no shortage of planar IEMs available, covering all kinds of price brackets. The PR1 is Kz’s entry into the planar battle, coming in at just over 65€ and using a newly developed 13.2mm driver that is different to the drivers used in many other sets.

So the question is, other than the price, does the PR1 provide anything that sets it apart from all the other planar models that are readily available?



Presentation…

The PR1 presentation is just another typical KZ package. A small white box covered with a transparent cover that reveals the IEMs inside.

The contents include the IEMs, the typical KZ cable, the typical KZ tips and the typical KZ user guide.

So, as far as presentation goes, there is nothing here that hasn’t been seen many many times before from the brand.

I have always said that the presentation is the last thing on my list of worries and that I would much prefer the money to be spent on the IEMs themselves than a bunch of accessories that I may or may not (probably the latter) use.

Saying that, many other brands have got us used to decent packaging and contents, making the KZ presentations lack in comparison, giving us a cheap vibe when opening the package. Again, this is not an issue, as long as the IEMs provide an experience that matches the price point.



Build and aestetics…

I have to say that I like the industrial looks of the PR1. They use a combination of a clear resin interior shell with a gunmetal grey aluminum faceplate. There are grills on the front of the faceplate, with more ventilation areas along the top. Now, these IEMs are well vented but by no means are they as open as the faceplates would lead to believe. However, it does add a great aesthetic to them, in my opinion of course.

The comfort is the same as the majority of KZ models, which I find to be quite comfortable with no issues over longer periods of having them in my ears.

As far as the cable, well, not much I can say that hasn’t been said many times before. It’s not a fancy cable but it does its job and is much better than the cables that KZ used to include in yesteryears.



Sound…

As I have quite a few IEMs that are pending review, I have been measuring them in batches, meaning that for some models I have seen the measurements before listening to them. THe PR1 are one of these cases.

I am mentioning this because when I saw the graph, my first thoughts were “oh no!”. However, when I got around to listening to them (quite some time after graphing them), I was expecting something much worse than what I actually found (not to say that what I found was amazing).

Here is the graph in comparison to my personal preference target:



Those of you who follow my reviews and know my tastes will be able to spot exactly what I am referring to by looking at the graph. That 10dB over my preference is the subbass zone is one thing but the 6 to 8dB over my preferences in the midbass range was what worried me more.

So I was expecting overly present and bloated bass, stealing the spotlight from the rest of the frequencies, yet it is not quite as bad as I expected.

I have said before that I have no issues with excessive subbass (which is certainly the case here) as long as it is clean and doesn’t lose definition, and the KZ are actually not too bad in this realm.

Moving through the usual frequency categories and starting off with the subbass, yes there is a lot. In fact, listening to heavy subbass tracks, such as my usual subbass test track “Chameleon”, there is a heck of a lot of rumble. It is in fact too much rumble for my tastes. However, in tracks that have less subbass presence, the PR1 doesn’t force it on you and it keeps more or less out of the way of the other frequencies.

If you are someone looking for a planar experience with plenty of subbass rumble, then I think that the PR1 has you covered.

The midbass is a little more invasive but is still not as bad as I expected it to be when looking at the graph. I will say that the midbass is not out of control though, at least with the majority of music. It does bleed over a little into the lower mids, or at least it gives that impression due to the dip in the center of the mids, but is rather composed and is not terrible.

Listening to things like “No Sanctuary Here” from my test list, the focus is certainly on the lower end, pushing the midbass above the level I would like to find on this are but it is tolerable. I do find it tiring but it is not headache inducing like it is on other bass heavy models (to me of course).

The mids do suffer from a scoop between the 500Hz and 1kHz mark, meaning that V shaped recordings will be even more exaggerated, especially towards the lower notes. This is something that many people find enjoyable but it is not something that I favour personally.

The upper end of the mids does climb rather smoothly to the ear, however, the presence between 2.5kHz and 3kHz is not quite enough to balance out that low end. It is not terrible, again, I expected much worse judging by the graph, but it is still lacking some clarity and definition, with vocals taking a back seat on many tracks. Sting's voice in “Walking On The Moon'' seems quite distant (maybe on the moon? ), as does the guitar, with the bass becoming the lead instrument (which some bassists would be happy about).

Moving into the upper frequencies, the extension is decent, with a sensation of air that is maybe not as apparent due to that low end being overly present. Using the typical “Code Cool” sibilance test, the results aren’t bad although they are not perfect either.

As far as details go, again they aren’t bad but they are not overly impressive for a planar driver either. To be fair, even the S12 that I really enjoy is not exactly a detail monster and none of them come close to what I have come to expect from bigger planar drivers, but the PR1 is certainly acceptable detail wise for it’s price point. Again, the excessive bass works against the sensation of detail, which does improve slightly by EQ’ing the low end down.

Soundstage is not a strong point in my opinion either. I did expect more width from a set of IEMs that looks to be fairly open but I’m afraid it is around average or even slightly lower. Image placement is ok inside the space it has to work with but becomes difficult to appreciate when the track is bassy. For example, “Bubbles” has a constant low rumble that takes away from the clarity and definition, and “Bubbles” is not exactly a bassy track.



Regarding isolation, well to be honest it isn’t terrible. It is actually better than average in the lower ranges whilst falling slightly below average as we get to the higher frequencies. It would probably have been better if it was the opposite (so the bass could be tamed naturally in noisy environments) but I am not complaining.



Conclusion...

If it wasn’t for the excessive bass ranges, then I would have actually been pleasantly surprised by the PR1, coming in as one of the cheapest planar IEMs on the market. In fact, with some EQ, these can be made to sound rather good for the price. However, as it is, I do find that the low end is far too much the “center of attention”.

If you are a bass head and are looking for a budget set of planar IEMs, then I think the PR1 should definitely be something you try out. The performance is also not terrible, it maintains its composure fairly well with fast moving dance tracks and I can see a lot of people being able to have a party in their head with their favourite dance tracks.

However, if you are looking for something that is more of a balanced sound, then I feel that there are quite a few alternatives out there that are much better suited, both in the budget range and in the planar range, if t
hat is what you are aiming for.

I can’t say that the PR1 is bad, in fact, if it had been released a year or so ago, before the planar boom, then it would have probably received a lot of praise. As it stands, there is a lot of competition going on in the planar IEM world and while the PR1 does have something that the others don’t (that 10dB of bass), in my personal tastes it is not high on my list of preferences.

General Info (Packaging/Build/Comfort)
KZ or rather Knowledge Zenith is a brand which everyone is familiar with and needs no further introduction. I got into this hobby with their budget model KZ ZST and back then, for the price they’re asking for, they sounded good and I'm not ashamed to admit it.

Fast forward to today, they too wish to take a slice of cake from the planar’s market and decided to release the PR1. In terms of packaging, they remain pretty barebone, a standard box consist of the IEM, cable and several pairs of eartips and that's it, more or less the same even for their entry level IEM, i personally think that they should at least include a storage pouch or some variety of eartips to correlate to the asking price, but that’s just me.

Build quality is good, the faceplate’s design is very refreshing, it looks like an open back but it is not, you can actually see the planar driver on the IEM itself, fairly big. The shell is not too big nor small, average to my ears and I can achieve a good fit with the stock M sized eartips. I wore them for several hours straight and I didn't feel any discomfort throughout my listening session.

Sound
The PR1 is a mild V shaped sounding IEM, boosted bass and high and slightly recessed mids. They are slightly warm and easy to listen to, with a tiny bit of planar timbre, it is not really that noticeable to me (subjective). PR1 is generally easy to listen to and non offensive

Bass

• Bass is emphasised with good texture and maintains good control (if properly powered)
• Bass extension is quite good, sub bass quantity is good and has a good rumble when the track calls for it, i have tried watching some video with it and it’s pretty good
• Mid bass has got good thump to it, it certainly need a little power here in order to have good control, else it will sound a little muddy during complex track
• Overall speed is fairly good considering the price

Mids

• Vocal sounded a little recessed but not too bad, i noticed that as you feed it with more power, the vocal goes a little more forward and not that recessed
• Male vocal has got good texture and also doesn’t sound thin, same goes to female’s vocal as well
• Instruments in the mid range has good note weight to it, Imperial March for example, the cello, violin, all sounded realistic and carries sufficient note weight to it

Treble

• Treble is a little boosted as this is mild v shape sounding IEM, but it is nowhere near sibilant or harsh, well done KZ, gotta give credit where it's due
• Extension is average but they made it up with good amount of air for good separation and imaging capability
• Nothing to shout out overall in the treble region, good amount of fun in an inoffensive way
• Detail retrieval is good but not decent, microdetails can be picked up but not expect totl kind of detail retrieval capability and you’re good to go

Soundstage/Imaging

• Soundstage is really good on the PR1, good width and height, a little lacking in terms of depth but quite good overall. It does gives off the sense of wide sounding, very enjoyable
• Imaging is surprisingly quite good, instruments can be pinpointed easily even in complex track

Driveability

• PR1 is not hard to drive, you can get decent volume even from Apple’s Lightning Dongle, but it does scale with more power, eg: vocal is a little bit more forward, better control on the bass and bigger soundstage

Final Thoughts
KZ PR1 is KZ’s first attempt in planar IEM, entering the planar market with aggressive pricing, and the tuning that they’re well versed with, V shaped with a little bit of tweak here and there and they then have a pretty good tuning that’s pleasant and inoffensive to listen to. We gotta give credit where it’s due.

Will I recommend PR1? Yes, why not? If you’re in the lookout for a pure planar IEM with limited budget, PR1 is the way to go, if you feed it with more power and better source, it will reward you with better sound. Peace out and enjoy music everyone! Till next time.

KZ PR1 HiFi - GOLD NUGGET


DISCLAIMER:


This unit was sent my KZ. Thank you Tyvan for sending this over. I really appreciate it.
So yes, they didn’t influence my impressions. There was no money involved, TRUST ME hahaha.


My descriptions might be too flowery and too good to be true, but these are merely the reflections of my emotions at the time of writing. I consider write-ups like my personal diary wherein I lay out my experience with the said set. Rest assured I will try my best to be objective as possible.
Talking about objectivity, I finally made a scoring system and ranking tier list to help me assess sound much better.

Also, I made my first impression video here:




SOUND PROFILE

Classic V shaped leaning to the brighter end. Hence the Hi-Fi, maybe? During my first impressions video, I was thinking of them being U shaped, but then decided to put them on V shaped category since they really do exhibit thay signature the longer I listened to them.


Bass is elevated with good control and with planar speed. It is north from my preferred target, but they do not sound muddy to my ears. Planar speed is just amazing, it is like a jab every hit. It slams, and they are gone before you know it. Even with this elevated bass, I did not hear them smearing the mids that much, apart from the change in tonal color of instruments and vocals. Bass texture is fine, not as realistic as Dynamic drivers, but the resolution makes up for it. You hear a lot of bass air on these. There are so many details in the lower region, but aren’t that full sounding compared to DD slam. Although I felt like the subbass is masking some of midbass and lower mids.


Mids are recessed, so is it bad? Not always, especially on nicely implemented tuning and driver capabilities. I find fundamentals aren’t too forward for my liking, and vocals aren’t in the same plane with the bass and treble. Because of the boost in bass and treble, plus the speed of planar, instrument and vocal timbre sound dry. I am pretty sure it is because of the added air in upper treble. However, as a planar, PR1 exhibits very good resolution. It is as clear as day. You will hear a lot of micro nuances. Heck you can hear dust haha. This is what planars do, and no doubt PR1 is no slouch if compared to more expensive sets.


Treble is extended. Too extended for me actually haha. They are not sibilant or harsh for me tho. I just find that cymbal resonance are too forward that I find it distracting in cymbal heavy tracks, which is like 70% of my library. The PR1 is very unforgiving in this area...You hear the completeness of harmonics..It will show the weaknesses of a track. You might even hate your favorite tracks and love the crap ones haha.


Now onto technicalities. This is amazing for the price really. It has got to be the most technical set under $90. It is so planar in technicalities. The speed, the resolution. The imaging. The layering. Everything is nicely done. Soundstage is very airy akin to a live session outdoors. I like it, but there isn’t much depth just like other planars. Imaging is accurate and ultra-focused; you hear the panning clearer than other sets. Pr1 is also able to layer instruments evenly. There is good proportion between the vocalist and instruments. The technicalities of PR1 is really a no brainer in this price range.


PROS


very good for vocals and music without much cymbals


Olivia sounds good on them. In the track "Drivers license", her vocals are very clear.. really clear that the air they produce almost sounds realistic. In Bruno mars' Versace, his voice sounded very good as well with good details.


the track "Rude" sounded new to me haha. There are so many details that are more forward than my other sets..


I thought that the bass in "hey steven" by Taylor was well resolved.. good texture without affecting much the vocals. The guitars sounded nice with good harmonics and a lot of air. Just really clear even if they are a bit recessed


The cymbals in "stay with me" by Sam Smith was surpisngly pleasing. Very good details and air. Aggressive cymbal genres definitely doesnt work with this set, but with mild ones, PR1 works wonders..


In M.J. "thriller", the opening of the door at the intro had very realistic rumble.


"I need to be in love" by carpenters had very good sounding instruments , vocals, air, and stage. it feels like a concert. Also in "yesterday once more" , those drums and tums had some very realistic texture man.. really good.


"dive" by Ed Sheeran had very airy stage stage and very clear vocals..


In "annamolly" by Incubus, the intro cymbals and guitars have very good resolution.. and that closing of hihats is so detailed.


"OD" by Polyphia sounded so atmospheric and airy demmm.


"sis anger" by Babymetal, the drum roll with other instruments at 1:24 - 1:32 were very well separated.


billie's "i love you", vocals are so damn immersive and has some very realistic layering.. even the voices talking in background had very real and clear space..


CONS


very unforgiving on the treble, its almost unlistenable to heavy cymbal tracks with bad mastering.. its not really harsh, but it becomes very distracting..


female vocals sounded a bit recessed in Millet's "ashes"


male vocals sound dry and not lush. Like any male vocal I have listened doesnt sound engaging. Kinda emotionless


late ear gain, so maybe that is the reason for dry sounding vocals


a lot of masking from subbass in the track "starlight" by baby metal. I also got the same finding in Creed's "Higher"


could have better packaging and accesories.


some sibilance. But they are surpisingly mild. I mean, it doesnt pierce as much as DDs do. I noticed this in IU's "Pallete"


P.P SCORE


TUNING - 2
BASS - 2.5
MIDS - 2
TREBLE - 2.5
TECHS - 3


= 12 ( A- rank, generally better than other sets. Very good for the price but the tonality might not match your preferences)

COMPARISONS:



I'll be honest, the PR1 does resemble the sound of most planars in the market. The only difference would probably be the tuning. Although, I have to admit that S12 and Talos have superior resolution and techs.


-P1 MAX has a warm neutral tuning. P1Max together with Talos, have the least planar sheen in all the sets I have tried. P1 MAX has better tonality. PR1 has better micro nuances


-RAPTGO HOOK X is better ofcourse. It has better bass texture and details. Better mids and vocals. More refined treble.


-MUSE POWER has an odd tuning. They were a bit shouty on vocals. So maybe PR1 is better in tonality here. techs are on par and PR1 is airier.


-ZETIAN WU is one of the best well tuned planars I have heard. The balance is just good for warm sound lovers. PR1 has better stage in terms of width and air. Other than that, I have to credit WU for the rest.


-DUNU TALOS is just superior in every aspect, and I cant get PR1 to sound like Talos even after EQ. It's probably because of the diaphragm KZ is using. I think they are using their in house ultra thin diaphragm they used on some models. I dunno. Maybe Im wrong..


-S12 is better overall as well. Even if the treble on S12 is also forward, I feel like it has better note definition and clarity. They may share the same tuning, but I have to give it to S12. But PR1 is cheaper here, so? You be the judge..


EQ

Planars are very responsive to EQ. The FR of PR1 is a perfect ground for EQing. It has a nice bass glide. Proper ear gain. And a linear extended treble. You can basically mold PR1 into anything.

My final video review here:




And for my EQ, basically it is more of a deductive one. My main concerns of stock PR1 Hifi is the amount of bass, amount of treble, and less vocal presence. So this PEQ addresses these concerns.


1. I reduced the 50-150hz region because I thought bass was not helping a lot with mid forwardness and fundamentals.


2. I increased 700hz for more accurate placement of vocals and a bit of warmth and presence. This is the only one I increased


3. I reduced 1500hz to remove unecessary shoutiness and thinness in vocals..


4. I decreased 6000 region for a less fatiguing listen. It also makes fundamentals pop up a bit. I also noticed that it lessenes a bit of planar sheen.


5. I decreased brilliance because I find it over extended and unnatural in cymbal heavy tracks.


All in all, this EQ makes PR1 HiFi sound very balanced. Very good lows with enough details. Engaging mids and forward vocals.. A less fatiguing treble with very good stage proportion. Better separation, layering and stage depth. Kinda trippy how instruments are placed really.. And I would say that this sound can easily compete with 150-200usd sets or planars, and PR1 is just around 60 bucks? Haha


I eqed this by ear. Meaning, i eqed it to my prefered sound and timbre. This might not work for you but you can adjust to your liking..


MY PEQ: Trippy


Filter 1: ON PK Fc 50 Hz Gain -1.5 dB Q 0.500


Filter 2: ON PK Fc 150 Hz Gain -1.5 dB Q 0.500


Filter 3: ON PK Fc 700 Hz Gain 1.5 dB Q 1.000


Filter 4: ON PK Fc 1500 Hz Gain -0.5 dB Q 0.500


Filter 5: ON PK Fc 6000 Hz Gain -2.0 dB Q 2.000


Filter 6: ON PK Fc 15000 Hz Gain -5.0 dB Q 1.000

FINAL THOUGHTS


I tried EQing the PR1 and they are very responsive. Toned down the brilliance a bit, and lowered down the bass as well. They sound fuller with better dynamics and realism.


PR1 shoud be the most practical buy if you want to experience how planars sound. I mean, I hear people EQing their S12 to get the most out of it. Only that, S12 is twice as expensive. So my thoughts are, if you are gonna EQ anyway, or know how to, PR1 is a no brainer.


However in stock form, I am kinda in two minds recommending this. I like to recommend this for its planar techs at a reasonable price, but at the same time, the tuning is a bit risky and I am pretty sure there are people who are sensitive to treble. The treble did sound milder with use, probably mind burn-in or maybe the tara-labs track I always use. Nonetheless, even after more than a week of use, I still find the treble to be too forward. You can experiment with eartips too.

PR1 really needs refinement. These are easily a GOLD for the price, but a NUGGET at that.


I am thinking of giving ot a 5 star after EQ.. or 4 stars for stock.. but I am really compelled that the sound of PR1 with EQ is the best you can get under 100usd.. like I said, it sounds like a 200usd iem.. Anyhow, I will give it 5 stars because for $60, what more can you ask?




WHAT’S IN THE BOX?

-usual KZ box.
-3 sets of eartips
-one cable
-done
-haha


BUILD and COMFORT


-build is good! I like the futuristic design in silver. KZ's build quality has been consistently good by the way. They really handle aggressive use..


-Comfort is good too! Not as bulky as ESX. Maybe like how ZS10 PRO fits, or ZES. The nozzles arent too small nor big, so they dont strain my canals that much.

Greetings!



This is a review of the KZ PR1 Standard and Hifi Ver., which both KZ themselves and Linsoul Audio have provided me to review.

DISCLAIMER: I WAS PROVIDED THE UNIT IN EXCHANGE FOR A NO-FRILLS, UNBIASED REVIEW. I AM NEITHER PAID NOR COMMISSIONED TO PROVIDE A SKEWED REVIEW.

The KZ PR1 is KZ’s first planar IEM (technically the CCA did it first, but they are sister companies, and this is KZ’s first planar on their own brand), dipping their toes in the wave of planar tech IEMs coming in the audio world like a huge tsunami of auditory nirvana. KZ, as the leading Chi-Fi brand in our market space, truly shows their prowess and experience in the industry while injecting their well-known tuning style into the mix. With a promise to be one of the cheapest options in the so-called “planar wars”, the PR1 is indeed an excellent choice if one wants to dive into the world of planar drivers and the unique experience they offer for your journey as an audiophile.

Presentation
I almost don’t have anything to say in the presentation side of things when it comes to KZ releases. They are like clones of each other: introducing themselves to you in a bleak and lifeless fashion. Almost every other KZ release has looked the same regardless of price range. In the world where Kinera, KBEar, BQEYZ, and other brands out there that can bring out a good packaging experience, KZ needs to step up their game in terms of how they present their product to their customers. It adds to the money-to-value perception of the product; an underrated yet essential part of buying a product.




Product
Upon opening the rather boring package, we are greeted by a *slightly* different product layout inside the box. The IEMs are displayed at the top-most part of the window, instead of it being in the middle. They are cradled by a plastic mold that prevents them from rocking during shipping. But everything aside from that, it’s all in the same fashion. The only unique experience is the IEM themselves, which features a nice and clean aesthetic to them. I appreciate KZ’s honesty in stating that the mesh inside the grills featured in the faceplate are just for decorative purposes only, and do not serve any real significance in the sound output. I both have the Standard and Hi-Fi Ver., and the only difference they bring aesthetic-wise is their colors (black for standard, silver for Hi-Fi). Both have the words “KZAcoustics” and “Planar IEM” emblazoned along the designed edges of the faceplate. Both look slick and non-distracting from the total silhouette of the PR1.



Particulars
Cable, tips, and manual. That’s all that there is. No further comments.



𝘽𝙪𝙞𝙡𝙙 𝙌𝙪𝙖𝙡𝙞𝙩𝙮 & 𝘾𝙤𝙢𝙛𝙤𝙧𝙩 (out of 5)

✳ Build Quality
Despite my woes in the way the KZ PR1 was packaged, KZ still pulls out all the stops in its build quality. Although not that heavy, one can still feel the quality of the alloy metal used in the PR1. It is rigid in all the right places, especially in the nozzle and the main body that will be touching your ears. The paint used throughout the entirety of the IEM seems to be of good quality too, as it has not exhibited any kind of wear, scratches, or chipping in the few days that I’ve used it extensively. Overall, the PR1 feels incredibly sturdy and reliable to use in the harshest wearing conditions. It slightly lacks my criteria of a slightly heavier and more substantial feel, but I feel it’s more of a personal subjective issue rather than an objective one. The cable and ear tips are where it comes off a downward slope. It’s still the very same cable and tips included in all their budget offerings, and yes, that includes the ultra-budget ones. My statements regarding KZ cheapening out in the packaging and presentation of their items apply here.





✳ Comfort
I feel that all has been said about how KZ IEMs fit in the ear of their listener. I have always appreciated how KZ shows their experience in shaping and molding their IEMs to a universal fit; this aspect truly shows in the PR1. KZ has spent years experimenting on different mold shapes for the bodies of their IEM lineup, and I think they truly reached an endgame peak here. Once you get the right size ear tips on, the IEMs fit as snuggly as possible on the ears. I have almost no woes on how they fit and feel in my ear, as they achieve that balance between a good, snug fit and a comfortable, light feel.

Signature
Both of the KZ PR1 versions offer the same innate planar goodness that the technology offers for its listeners. The nice planar sheen, endless amounts of treble extension, and godlike imaging capabilities are there to stay. However, these two releases from KZ operate like fraternal twins: they came from the same roots and share multiple similarities, but there is a noticeable difference between the two that oddly rhymes with each other and warrants attention from the audiophile who has the capability to have them both. The standard version offers a more natural timbre that results in a more engaging experience without sacrificing the technicalities that we all expect from planar drivers. The Hi-Fi version offers the planar experience, but in steroids: it sacrifices some of the engagement for a flatter, more critical auditory feel that is catered for the more purist listeners. Combined, they form a mighty union in an audiophile’s collection that can be interchanged between each other depending on their moods and wants for the moment being.
✳ The bass essentially operates the same way between the two IEMs. Accurate, fast, and stings like a bee. Both also have a nice extension to the extreme lower frequency ranges that provides some rumble when a song calls for it. However, the Standard Ver. amps up the mid-bass response of the PR1, resulting in a meatier and a punchier experience than its Hi-Fi counterpart. I subjectively prefer this version as every bass hit feels like a Mike Tyson punch: fast, deadly, and full of authoritative power to justify its existence. This is honestly one of the best KZ bass responses that I have ever heard in their lineup, and it is truly appreciated they went for this one as their Standard. The Hi-Fi Ver. is nothing to skip out upon too, as it also provides a good bass experience that is more akin to a Pacquiao punch: stealthy, lightning fast, and hits on all the right places. It may not be as authoritative as the Standard Ver., but it still holds out on its own. The bass frequencies are where most of the differences are noticeable, so decide upon what you prefer between the two in terms of their bass performance.
✳ The midrange between the two versions, despite some slight differences in timbre and thickness, are intrinsically the same. In my own humble opinion, this is the closest that KZ has approached the “Moondrop VDSF” sound. I can hear so much similarities on how it is executed, most especially on the lean and crystal clean nature of how the everything is rendered in the midrange. This is particularly evident in the Hi-Fi Ver., as it forgoes the engaging nature of the Standard Ver. to prefer a more critical and “balanced” nature. The Standard Ver., as mentioned previously, slightly skews away from the lean nature of its counterpart through a slight elevation in the lower midrange region, which is a direct effect of the mid-bass rise that it has. Due to that, it has a slightly (in every meaning of the word) thicker and “warmer” timbre than the Hi-Fi ver. This is evident in lower male vocals, as the Standard Ver. has a more forward and meatier presentation of it than the Hi-Fi Ver. Despite the differences I have said, do not take them as VERY apparent night and day differences. These are just minute yet perceptible distinctions that warrant the change-up between the IEMs ever so often.
✳ The treble response for both of the versions are excellent, probably even the best KZ has sounded over their lineup. It perfectly follows what is expected for a planar driver to sound like, notably its sheen. If you are not oriented what a “planar sheen” is, here is the best I can describe it to you: it is like a hybrid/marriage between shimmer and airiness, if we’re alluding to terms usually thrown around in the audiophile hobby. I think the PR1 is a better introduction on what to expect when it comes to planar drivers, as I think it is the cheapest way to hear that. Yes, I’m excluding the Celest Gumiho for that case. I shall delve deeper as to why that is the case in my upcoming full review of the Celest Gumiho, but generally, I think it is a different beast of its own compared to the PR1. This IEM brings out the best out of the “planar sheen”: it shines very well in the upper treble frequencies with proper body to back it up. It also extends almost infinitely into the upper echelons of the audible frequency spectrum to ensure a nice amount of air is being produced. The only notable difference between the two versions is that the Hi-Fi Ver. seems to have more elevation in the upper treble frequency, which results in a tad bit more shine and shimmer than its Standard counterpart.

Soundstage/Imaging
The planar tech again shows its prowess here by giving us excellent performance in terms of soundstage and imaging department. Again, this is maybe the widest that I have heard in KZ’s lineup in terms of soundstage. The wideness is greatly complimented by an above average height in its presentation; there are IEMs that have far more height than this one, but the compliment between the wideness and height that the PR1 offers greatly lifts it up against its wider staged peers. Because of this nice cohesion in the soundstage department, the imaging is nicely affected by offering us a nice, clear picture of the auditory painting that each song is presenting to us. One can easily pick up the different instruments used in any song. Good stuff.

Foreword

1. At the point of this article, my PR1 has undergone over 100 hours of burn in and approximately 50 hours of actual listening
2. I don't do measurements, I just describe what I hear, from my own POV
3. I don't use EQ
4. The entirety of my impressions was done with my own Foam Tips
5. Ultimately, my reviews are purely subjective and biased to my personal preference in sound

Not to be left out, Knowledge Zenith released their first Magnetic Planar to an already crowded Planar IEMs market under their core branding of KZ.

The Build


Nothing much to say here really with build and packaging. As per usual with KZ marketing strategy, to keep their offering very budget friendly, they minimize a lot of things and thus the overall pricing would be affordable.

The IEM itself, built on new 13.8mm flat Magnetic Planar drivers. The shells, I frankly have no idea if it is metal or some sort of pseudo metal composite material. But the design is simple and not too extravagant. I actually like it this way, not attempting to look lavish especially when the intended design to is to provide something functional and wearable.

Aside from the most spartan looking silicone stock tips and the cable, it really is simple. For this review I have opted not to use both of them. Primarily because my unit comes with MIC type cable (which I have no use for) and silicone tips are the least favored for my own personal usage.

Despite seemingly metallic in construction, PR1 has average weight which is light enough to not induce any unsavory weight. Wearing my PR1 also proved to be hassle free - it is fairly comfortable with no tendency to induce wear fatigue even after 1 hour.

Sound Impressions
This is a KZ earphone we are talking about, so it is no surprise that the overall tuning for the sound being V curved. Definitely KZ house sound. There's pronounced elevation and boosting of lower frequencies with suppressed Mids and heightened tilt for the upper region. The good thing is, I would say the V tune of this PR1 is mature and sensible.

PR1 dynamic range is fairly well extended on both end especially on the lower frequencies. Dynamic presentation and transients being tidy and smooth. It has very sensible vibrancy to the manner to the energy and pace, never too euphonic - it is fun as it is amply polished. Perhaps from certain angle it would also appear crisp with mild hint of granular texture.

Timbral balance is something that I need some adjustment getting used to. Yes it is definitely Magnetic Planar sort of timbre, but due to the strong V curve tuning, I need to reorient my senses to grasp the flow of the harmonics - this primarily because I am so used to flatter sound frequency of Diffused Field Neutral that the sound coloration masked my perception to the nature of PR1 timbre. Once aligned, I would say that PR1 is amply organic and smooth, natural enough to not sound metallic or dry. Is it warm then? not exactly - PR1 seemingly offer good balance of brightness/warmth

As expected with most V tuned IEMs, the Midrange of PR1 appeared stepped back with the staging and placement. This is clearly exhibited when using PR1 with songs that are already mixed/mastered with V sound curve, something like Rock/Metal which typically suppress the Mids - the results being sometimes the Mids would appear slightly distant. However with other recordings of Jazz, Ballad, Folk or any of those that were mastered with more balanced waveform, PR1 Mids would then sounded less recessed. The good thing is, PR1 Mids actually sounded neutral and natural tonal wise - I am hearing believable instrument tones that offer tidy texture with clean edges. Attack and decays are aligned with would be typically heard from magnetic planars, well controlled energy and speed - not exactly as fast as Balanced Armature or true Electrostatic units. The only magnetic planar IEMs that I would consider as deftly speedy in this regard would be 7Hz Timeless and DUNU Talos. Otherwise the attack and decays for PR1 Mids are practically on par to the likes of TIN HiFi P1, Tangzu Zetian Wu, Letshuoer Z12, Moondrop Stellaris etc.

Vocals on PR1 sounded smooth and naturally textured. Works well equally for both male and female. The undertones can perhaps be regarded as slightly crispy lush with edge smoothing. What's important to me, PR1 handles high pitched Soprano-Alto type of singing really well - which means the likes of Alison Krauss and Mariah Carey will sound great with PR1, despite the seemingly stepped back presentation. Switching to vocals with lower octave, PR1 would present them with a bit more perceived warmth and lushness - such is the case with Diana Krall, Sinne Eeg and Morrissey. Overall the resolution and imaging of vocals is fairly good for a V tuned unit.

As for higher frequency performances, PR1 must be commended for keeping it very well controlled and smooth. I am hearing solid presentation with good sense of air and sparkle - transient interchange flow from upper Mids all the way to to decay stage being fluid and admirably extended. Good Macro and Micro details too, not overly pronounced, Treble is well resolved with no hint of offensive spikes or wobbly presentation. Despite not being clinically crisp like some Balanced Armature output, I can hear brushed Snare drums cleanly - this is an important element especially for listening to Jazz, where Treble elements usually are recorded at subtle density. Cymbals and Hi-Hats sounding realistic - no indication of being unnaturally metallic or grainy.

Now, as would be expected with any KZ IEMs, Bass is in abundance. Let's start with the amount and density. Bass body mass is expansive with good depth and resolution. Yet despite all this, PR1 exhibited great maturity and control with the vibrancy of the presentation - it has sensible amount of seismic sensation almost as strong as would be expected from dynamic drivers. Midbass offer tidy and smooth impact and slam, no indication of bleeding unnecessarily into lower Mids or Sub Bass. The decays observed with Sub Bass is very Harman-ish actually, the dispersal giving indication that the extension goes deep and graceful. Despite me not liking Bass heavy IEMs, I cannot find fault on how PR1 presented it - especially not at this price point.



Technicalities
In all fairness, KZ1 offers solid technicalities. Soundstage being wide and spacious - imparting big open sound that I find pleasing. PR1 has the ability to resolve with clean imaging despite not being as clinically crisp as how I normally would prefer it - but then this is also an element that contribute to PR1 being smoother in the overall scheme of sound - less edgy. Spatial positioning appear amply holographic, perhaps just lacking a bit of sharpness with imaging and separation - but it is clean enough that it is still possible to track individual notes.

Speed and resolution - no issues here in general. I did not observe any worrying deficiencies with PR1 even when subjected to handling of complex and fast contents. No instances of PR1 being muddy or sluggish, truly admirable.

Scalability
Rated at 16 Ohm and 96 dB of sensitivity, PR1 does need a bit of power to shine. Yes of course still usable with weak powered sources like my phone output, but I really need to crank the volume above 75% to get proper listening levels. Pairing PR1 with 2 Vrms of power is where the real deal is, even better as the power output goes higher - not uncommon for most magnetic planars. When properly powered, PR1 will then present graceful dynamic presentation which is rich and wholesome, where technical element of PR1 becomes evident.

Final Words
KZ PR1 is quite likeable especially if the listener already accustomed with V tuned earphones. I like the way that how well balanced PR1 is as a whole package and despite the budget classification, it does not sound like a budget IEM at all - that's how I am hearing it. Despite being a zealot of more neutral sound, I find myself enjoying my music nonetheless with this vibrant and fun sounding unit. To a certain extend, I can imagine PR1 will even qualify for on stage monitoring due to the richness of Bass output which is needed to offset the thick ambience of stage presentation, that's how good I personally think KZ PR1 is.

All in all, it is definitely a very positive step for KZ going ahead. I hope that KZ will continue to innovate for even better units while keeping it highly affordable. PR1 is a no brainer recommendation for highly affordable yet properly tuned IEM.

• KZ for this KZ PR1 HiFi Edition Planar Earphone

Package Content & Design
KZ PR1 comes well-protected in a simple white package. Mine is HiFi edition as you can see. Besides KZ-PR1 with medium size ear tips, there are user guide, additional 2 pairs of silicon ear tips (S & L) and 120cm silver-plated cable.



Have a closer look at the durable silver-plated cable. It is loaded with high-purity oxygen-free copper wire core that provides efficient transmission efficiency. The silver-plated layer on the surface of the wire core can reduce signal attenuation. By the way, you can also opt for cable with high-sensitivity microphone. Great for phone call no doubt.



Outstanding build quality! All thanks to hollowed-out aluminum alloy cover and electroplating bottom shell. In addition, it is stylish and looks great with metallic texture. Rock-solid that surely will protect the 13.2mm dual-cavity planar unit inside. Besides, it comes with 0.75mm standard gold-plated plug, widely applicable to 2 Pin cable. You can change the cable easily when needed.



Fit, Comfort & Isolation
KZ PR1 is designed to be worn over the ear. Yes, it is comfortable to wear for long hours. And it fits very well too. Just pick the correct ear tips size that matches you will do. Besides providing comfort, the ergonomic design helps to keep the earphones securely on my ears too. In addition, it has excellent passive isolation. It can block some of the environment noises while music is being playback. And seldom notice microphonic from cable too. That’s good.



Sound Quality
KZ PR1 HiFi Edition is easy to drive with 16Ω impedance. Most smartphone should have enough power to drive it. Of course, it is even better on external DAC like Zorloo Ztella. And you don't need to be an audiophile to discover the greatness of PR1. Your existing smartphone and tablet’s audio quality no matter iPhone, iPad or Android device will level up automatically. And don’t limit PR1 to high res music only. It shines on the usual stuff like MP3, YouTube MV, games and movies too.



Overall, KZ PR1 HiFi Edition has balanced toward slightly bright sound signature. Detailed and dynamic. Excellent soundstage and imaging. All width, height and depth are wide indeed. Yes, instruments placement separation is clear even in the complex scene. Arcason by Candido Camero and Oh by Dave Matthews surely perform very well here.



Highs are airy and detailed. Sharp and clear with no harshness. This is the place where PR1 shines. Mids perform well too. Vocals no matter male or female sound natural. Great clarity and resolution. Vocals and instruments' separation is great too. Yes, I do enjoy the clarity of the guitar and sweet female vocal. For lows, PR1 continues to perform. It is deep and punchy yet not overpowered.

Advantages

• Crisp, clear sound with amazing bass
• Detail and dynamic
• Wide soundstage
• Outstanding build quality
• Comfortable for long hours

KZ Pr1 Hifi Review​

One after the other Planar iems are trickling into the iem’verse. Every brand comes out with their own iteration of what a Planar driver iem should look like and sound like. Each Company taking their turn. Of course, KZ would join in on the fun.


A special thank you goes out to Tyvan Lam and KZ for providing the KZ Pr1 Hifi for a fair and honest evaluation. I say it all the time, in no way does this affect how I conduct a review and thankfully anyone who sends me anything knows that. It’s a bonus for the company and the reviewer. I get to do what I love and highlight and talk about audio gear and the Company gets some opinions and exposure of thier audio gear. However, the company is the side which takes all the risk and for that I say… “kudos”. Put your money where your mouth is and let the reviews fly. Good or bad or indifferent. This is how we get better after all.

KZ is a behemoth of a chifi audio brand known for making products which seem to defy the price tag. I have had quite a few from the brand in my time and rarely am I dissatisfied. This new line of planar driver iems actually has two brand new additions, like I said the KZ Pr1 Hifi and the other unit is the KZ Pr1 Balanced. Again, today I am reviewing the KZ Pr1 Hifi Planar iem… let’s check It out.



Gear Used
–Samsung Galaxy Z Fold 4
–Fiio Ka3
–Ifi Go Blu
–Fiio BTR7
–Ibasso DX240 w/ Amp8 Mk2

Packaging​

Really not much to report. The Pr1 comes in another small KZ box. Accessories are bare bones and so I don’t anticipate much reporting on this subject. You get your ear tips, in this case the White Starlines from KZ (I’ll always like Starline tips BTW). Also, you will receive the normal white KZ cable which you get with even their ultra-budget iems. That’s about it. For $80…its sparse. I certainly do wish that we would see more for the $80 price tag. I suppose KZ put all their efforts and pricing into the earphones themselves as well as the tuning among other things which aren’t the accessories. It is what it is folks.

Build / Design / Fit​

Build Quality​

The Build is rugged enough. Maybe rugged is the wrong word. The build is solid enough. The Faceplates are made out of aluminum which feels nice in the hand. Glued to the face is a solid alloy shell. Everything is smooth and free of rough spots or irritating edges. Lines are clean and free of any unsightly marks, burrs, or fabrication defects. The nozzle has a lip to keep hold of the Starline ear tips (or whatever tip you choose). Ya the build is fantastic, I have no reason to believe anything different.

What’s Inside? ​

Inside those sturdy shells that I just described is a 13.2mm Planar Magnetic Driver within a dual cavity design. KZ refers to this as a “Nanoscale Diaphragm”. This is newly developed Planar sports an ultra-thin silver-plated diaphragm with an N55 double-sided magnetic circuit array system. I can attest that I have not seen this driver out in the wild so… right on KZ! I guess we can officially confirm the Pr1 as the cheapest ‘actual’ planar driver on the market.

​

Design​

I love the style chosen for KZ’s first foray into the planar space. The design is fantastic to me, looking flat out dope in my opinion. KZ added that faux (open back) grill on the back and I love the pattern they chose. Small writing on the Faceplate says, “KZ acoustics” in one spot and another says “Planar iem”. I just like the style of this set. The Pr1 looks like a planar to me, and I can’t really begin to reflect why that is. I like holding two metal shells in my hand as I can feel the scraping and tapping of the metal clinking and clanking against each other. It’s simply a more premium feel which adds to the aesthetic overall. Very cool design KZ, not bad at all.

​

Cable​

Ugh, KZ! The cable fellas?! What is up with the budget cable? I don’t like it. Flat out and hands down the cable needed an upgrade from me. I don’t think this is a sonic requirement as the old KZ cable does do the job however, this is just my subjective experience. Right away I swapped cables to the Tripowin Zonie Balanced ($19).

There are a couple reasons for the change. First, in my humble opinion this set likes a bit more power. It’s easy enough to drive but most certainly gets better with more juice. More on that later. Second, the white cable doesn’t do this set justice, it doesn’t go with it aesthetically and I had to switch to something to match that silver look. Another reason which is a personal gripe; whenever I go to roll up the cable it simply blows up the second, I set it down. It makes it difficult to photograph but more importantly it doesn’t fold over easily and lay nicely like a decent upgrade cable. You have cable spitting out everywhere and it is simply an annoyance. Let me say it again though, this is simply my personal experience and there really is nothing sonically wrong with the included cable.

Drivability ​

I consider the Pr1 easy enough to drive to good volume, but I have found that more power equates to better sound ultimately. The Pr1 has a 16-ohm impedance which is nice but a sensitivity of only 96 dbs. Trust me, give it some more power if you have it on hand. If not, you’ll be okay with this set. More power does slightly calm down some issues that I’ll describe later.


The Ibasso Dx240 on high gain seemed to help the Pr1 shine the best for me. Though I did like the Fiio Btr7 and IFi Go Blu just fine as well. Both gave enough power and synergy to make a nice listening session or two. I suppose a pretty powerful dongle dac will do just fine. I didn’t like the Fiio KA3 paired with this set to me and instead went with the Go Blu and the DX240 for the majority of my listening. The KA3 seemed to egg-on that metallic planar type of timbre more than my other sources.

​

Quick Sound Impressions ​

The Pr1 is a slight V-shape I would say. I hear a warm of neutral sound in the lower half and a slightly brighter upper half. The low end actually has some bump to it. I hear a well enough extended lowest of lows while the mid-bass is slightly less pronounced. The bass does have some decent texture for a planar iem.

The Midrange is recessed and maybe not exactly as forward as I’d like but they are clear and very clean to my ears. I would like a hair more energy, but I’ll explain my thoughts on that later.

Treble is also clean and detailed, spritely and energetic. Extension is nice in this region as cymbals come through well on the Pr1. Timbre is a bit off here with some slight tiz, some would call that the left-over debris of “Planar Timbre”. Technically speaking this set is great though. Details shine through very well; the stage is nice, and the imaging is good.

Not a bad first attempt…​

Honestly, I would say that the Pr1 is a good first attempt by KZ to bring along a budget Planar Driver iem. It has issues but those issues don’t condemn this set. Honestly every iem has some sort of an issue and this especially rings true for the budget sector. You will likely read many of those issues in this review but make no mistake, the Pr1 is a good set.


Anyone who wants to hear a Planar iem for the first time and they don’t have a ton of money to go to the higher pedigree planars… I’d check out the Pr1. The issues present are petty for what you get and truthfully this set may surprise you with how well it can perform once your brain adapts to it. Before the meat of the sound part of this review even thoroughly begins, I want to preface everything with; I really do think this is a good set for the price point.

​

Bass​

Planar bass has come a very long way folks. There was a time when the low end of planar driver iems (at least those which I’ve heard) was so analytical and thin and even dry. Speed was a problem as pace and timing just didn’t reflect real life sounds. The presence of real deep growl and authority seemed to lack. The Pr1 corrects that to a slight degree as the low end here has depth and has some slam with actual texture. You can feel as well as hear the bass on the Pr1. Still, these don’t replicate a good Ole’ dynamic driver. This is most certainly planar bass but there is still an atmospheric presence which is something to applaud for the price KZ is asking.

Sub-bass​

The lowest area of the mix is extended nicely. I almost hear that dynamic driver type sub-bass. Almost. The sub-bass kind of steals the show in the bass region. I will say with complete confidence that the Pr1 surprised me with a low reaching reverberant tactile judder. Texture is evident and the Pr1 does so with a speedier attack and decay and decently rounded edge at sustain. Speaking of sustain, it is there but mostly the speed of a planar is evident, it is tighter and offers a nice ending to bass hits. Still, there is the missing organic and tactile sound of a dynamic in my opinion, however good for a planar which has other strengths.

Mid-bass​

The mid-bass has some oomph and slam but not to the level of the sub-bass. The mid-bass could be lifted a bit and that would do well for the replay as a whole. It isn’t the type of bass which encroaches over midrange frequencies. This can be good and there can be drawbacks. The Pr1 does pretty good for a planar to give genres such as hip-hop just enough weight and presence to play well with them. This is not a bass-head iem at all, but it also doesn’t lack bass. I’d say that the Pr1 is just missing an adequate amount of force and concrete palpable slam in the mid-bass. Not quite there but satisfying, nonetheless.


One thing is for sure, I don’t hear that plastic, lifeless and anemic type low end on the KZ Pr1. I would like a bump or two with a bit more color to the mid bass, but that’s just me. Let’s put it this way, on “Survivor’s Guilt” by Saba I hear a deep enough haptic buzz during the bassline and Saba’s voice is very clean and clear. So, there are rewarding points to the tuning. We could go a lot deeper into how it effects all areas of the spectrum but… I go way too long as it is in my reviews.

​

Midrange ​

Low-mids (Male Vocals) ​

Male vocals are important to me, and I always look for a certain warmth and heaviness along with s certain edginess to note delivery. I do hear that planar timbre to a degree. Male vocals on the Pr1 don’t quite get me to euphoria. This may be due in part to the mid-bass not pushing into the Mids as much, couple that with the recession in this area. Males, both baritone and tenor have a slight lack in vocal heft. They sound a bit dry and underwhelming and a bit non-resounding. There is also a lack of that visceral energy that a man’s voice naturally conveys.


I wouldn’t say this set replays this area bad but there is that thinness which a planar can exhibit. The Pr1 does have the speed of a planar, with the timbre of a planar, but no real warmth and fullness from the low end. The lack of weight is pretty evident without that low end push. Yet there are nice benefits. The Pr1 actually has nice clarity and technically is pretty darn good. The lower-mids could be just a bit more forward and I could use some warmth from the bass region a little bit. However, I am being very picky, in truth I am positive that many will enjoy this area of the KZ Pr1.



Larry Fleet has a song “Where I Find God“. Larry has this low but edgy and weighty inflection to his country voice. His voice cuts through the melody surrounding him and there should be an edgy crispness and fullness to his voice. Listening on the KZ Pr1, instead of full and weighty with a course edge, it comes across rather thin and edgy and withdrawn. Still nicely displayed but not quite there for me. The lower mids carry nice details and with nice resolution though and in totality they really aren’t that bad. I simply love my vocals. Still for a cheap planar you are getting that true planar speed and you are getting it for a low cost.

Upper-Mids (Female Vocals) ​

Females have good eloquence and good emotion for the most part. I hear pretty good energy in this area on the KZ Pr1. That said, there is a lack of shimmer and shine to female voices. I could use a bit more of a controlled sheen. However, the softness to a woman’s voice is not lost. There is still ample vitality for ballads as well. In the same breath, there is almost a faint dullness to the sound. Ella Henderson with her song “Everything I Didn’t Say” should be emotionally wrapped and full in sound while remaining softly contoured and subtle at the same time. Instead, there is almost a prevailing feeling of this area being held-back. To counter that, once again resolution is great, separation and placement are good. This set is almost there, but all in all, females still have good enough energy to carry most tracks.


Instruments have a nice cadence, perhaps not the most timbre perfect but they are clean. All the technical aspects of different Instruments are spot on as well. I suppose this is where the KZ Pr1 begins to stand out against the competition. This set takes whatever I throw at them, and they speed right along not skipping a beat. Strings, percussion etc. all benefit from the separation afforded by the planar driver within. More on that later.

​

Treble​

The highest region of the frequency is certainly boosted yet doesn’t come across too bright to me. I hear that planar timbre the most in this region where it seems to be elevated. Instruments sound like they have some decent body to them. There’s nice extension to instruments like cymbals, flutes and the sax etc., all of which sound just fine besides the planar inflection. Cymbals for instance carry a nice chisk and aren’t drowned out or attenuated. For the money KZ is asking there is much worse that you could buy. The biggest drawback is that the boost in this region kind of accentuates the metallic tiz and without the warmth from the mid-bass to counter this elevation it comes across very shizzy and planaresque.

Planar Timbre at times​

That Planar timbre that I’m referring to is a very slight metallic “TIZ” sound which follows notes. It is actually hard to explain but those who know…know. There is an emphasis at what seems to be the decay/sustain level of a note delivery which interjects an almost energized tiz to the overall timbre. It can go unnoticed after a while as it has with myself. After brain burn that is. There is most certainly that Planar timbre, but I don’t think this is a real issue as it should be expected to a small degree. Also, I think with more power it does help to dial that back. I did try burn-in to see if that would squelch it, but it did not. Truthfully it doesn’t bother me, and I still get lost in the music.

The Trebles saving grace​

The benefit is the technical ability in the treble area, as well as the fact that there is nothing sibilant, peaky or sharp to the sound and also there is good extension of the highest region. I never heard anything grating and trust me I tried to find it. Perhaps the Pr1 takes me pretty close in a brighter track, but I have yet to throw these out of my ears or rush to turn the volume down.


Honestly besides that slight shizzy & tizzy metallic sound, the treble is not bad at all. Extension is adequate to good. Yes, it isn’t the most natural sounding treble but that kinda goes with the territory. The truth is, I can sit and enjoy the sound emanating from this set and not think at all about any issues when just casually listening to my favorite music. In the big picture this is a great entry into the planar world.

Soundstage/Separation/Imaging/Details​

Soundstage​

The soundstage is actually bigger than average. Width, height, depth all is spread out to me. Obviously, there isn’t some cavernous breadth of space (it is an iem after all), but the stage is large enough to notice. This gives ample room for other technicalities to play around.

Separation​

Separation of instruments and voices is stellar. I hear almost no blending of sounds. All elements of a stage are nicely partitioned off and etched out. The swiftness of this driver is such that it almost creates space in the psycho-acoustic imagery within my music.

Imaging​

Placement of instruments and voices is also done very well. Not only is everything separated but everything is also in its own spot within the stage. I hear centered vocals (per the recording) which play in front of me. Instruments playing around me sound partitioned off and I can zero in and hear most pieces within the stage nicely. I found no issues with imaging at all in fact. The KZ Pr1 seems to really create a controlled environment which is good for the price point. I don’t think the Pr1 punches above its price here, but it definitely equals some of the better iems within the price group of $50-$100. I think this is another area where the Pr1 excels.

Details​

I’ve mentioned this already and I will say it again, details are pretty easy to discern with the Pr1. I don’t find the tuning too much of a detriment to technicalities as the speed of the drivers and the ability of those drivers to illuminate small details is pretty darn good. I don’t think that this set is leagues above its price point with details either, but it easily takes on the better detail oriented iems under $100.

Conclusion​

This set is for anyone who is curious about the planar world, and I think this is a very nice entry into that space. For all of the small nitpicks that I’ve done throughout this short review I have to say that I am overall pleased with the KZ Pr1. I like the sub-bass depth and rumble and the technical aspect of this set.


The KZ Pr1 does compete well against the competition under $100 in a number of different factors and all things considered the tuning is not bad to my ears. I certainly would never condemn a set which is reasonably tuned with planar tech, at the price it’s at in a market which hasn’t seen a planar iem so affordable. I think KZ did a great job truthfully. Let’s put it this way, nobody else is doing it at a lower cost. Of course, for $20 more you could spring for the 7hz Dioko at $99. However, if $80 is pushing your max limit in spending and a planar is what you are after… I suppose KZ has the market cornered at the moment for this price.

Yes, we could always find little issues, but in truth the Pr1 handles many genres, and I don’t mind keeping them in my ears for long periods of time. Technically the Pr1 seems to excel among other areas where they actually compete very favorably against the competition. I think that if KZ matures in their tuning of this driver tech and shifts a few areas of the mix there is no telling how great their future planars will be. This seems to be the trend with KZ as a company as they build on past attempts to create products which actually defy price tags and cause much hype. I walk away from this review thinking this is a win for KZ no matter what the end result is for the KZ Pr1.


Thank you to anyone who read all the way through this review. I love to write my thoughts about a hobby which a truly enjoy and love. That said, please don’t stop at me. Take in other reviews and read or watch other perspectives from reviewers across the community. We simply aren’t all the same, we have different likes and dislikes, we have different gear and even different hearing abilities among a slew of other factors which could sway the thoughts of any reviewer. Also, everyone is always right in this hobby because audio is a completely subjective experience. Don’t hang only on my word is all I’m saying.


Well, that is it. I had a great time reviewing this budget planar set. I’d say that KZ did a great job, and this is a worthy iem for anyone who is curious about the technology. Please take care and stay safe everyone.

IEM/Earbud/Setup configuration: Stock medium eartips, stock cable, any form of EQ or MSEB off, 40-60% volume, both high and low gain, with and without extra amplification.

Sound signature:

• Much like the KZ EDA Balanced, the KZ PR1 HI-FI version aims to sound “neutral” while keeping the company’s promise to be an all-rounder IEM for the masses. If we’re being specific, it sounds neutral-u shaped to my ears most of the time, with very good technical performance as most planars should be.

• Planar sheen - Its definition is quite difficult for me to describe with words, but it’s a certain characteristic where the transients seem to exhibit shimmer, sparkle, and air quickly. A bit better and less prone to peaks versus what piezo do. It is better to hear and observe IEMs and headphones with planar drivers to fully grasp what I am experiencing. Credits to Goji-Fi and sir Eiji for giving me the idea for this definition.

Lows:

• The lows of the PR1 HIFI is slightly elevated, midbass-focused, but never skimped with subbass presence as it is present at a very good amount whenever the track calls for it. Its decay and attack are snappy and still managed to sound really good and alive on bass heavy and EDM tracks. In a nutshell, its bass is punchy and clean while giving the fun factor the song needs.

Mids:

• The mids are slightly recessed and may even sound “too relaxed and thin” when underpowered, or plugged in directly in a non-hifi smartphone like LG G/V series. But when powered, it is “naturally” bodied with a very good amount of texture and detail. Male vocals and instruments exhibit good thickness and texture in this IEM. It might come across as “lifeless” on some tracks but I think it is more of a driver characteristic than intended tuning (since it aims to sound neutral at most) , but I might be wrong so there’s that. Female vocals are slightly elevated, clear, detailed, and airy. However, this is the part where the PR1 HIFI will sound unforgiving and quite revealing for me. Poorly remastered tracks will sound compressed and unrefined here in this IEM. This doesn’t bother me at all but I do see people that might find this as a con, so I have to acknowledge it. Despite it being unforgiving, there aren’t any abnormal peaks, pierce or any sibilance present - much like what the KZ EDA Balanced exhibited for me.

Treble:

• Moving on to the treble, it is well extended, airy, and detailed. Cymbal crashes have that extra shimmer depending on the track, maybe because of the planar sheen. Detail retrieval is above average because it manages to pick up microdetails easily.

Technicalities:

• In terms of technical performance, KZ and the Planar driver did the PR1 HIFI really well here. Soundstage is wide with above average expansion. It is more or less as wide as the KZ ESX. Soundstage and layering here is also excellent for its price and manages busy tracks easily without being congested. Imaging falls on the precise side in my book, but if I have to nitpick it could be better since it sports a planar driver. Nevertheless, it still manages to render vocal and instrument positioning clearly with good spacing between the elements.

Pros:

• Well-tuned, first (technically) planar IEM from KZ.
• One of the “neutral” sounding planar currently under 200 USD.
• Excellent technical performance for its price (as it should, it’s a planar).
• Snappy attacks, decays, and transients.
• Fatigue-free sound.
• Controlled, non-lacking lows.
• Open, musical mids.
• Well-extended, non-fatiguing treble.
• Very good layering and separation.
• Excellent fit and isolation
• Sturdy build quality.
• Actually decent stock eartips! Managed to sound the same to KBEAR 07’s sound effect.
• Industrial design cues will fit most modern aesthetic/motif (subjective)

Cons:

• The sound follows the KZ EDA Balanced sound philosophy, which means it may sound “relaxed or laid back” due to it targeting neutrality. (subjective)
• Like most current Planar IEMs, this has the “Planar Sheen” driver characteristic to it. Still, it isn’t sibilant, harsh, or anything in between by any means.
• This IEM may be unforgiving and revealing on poorly mastered/recorded tracks.
• Barebone accessories should not exist for its asking price.
• As most planars do, this needs an extra power from a dongle to sound to its best. (not really a con since that’s how planar works).

The KZ PR1 HIFI is now my top planar IEM recommendation under 100USD! If it only managed to exist as I wrote my 2022 IEM ranking list, it would’ve been in the S Tier as it balances both tonal and technical performance really good. However, I will only recommend it if you have a dongle or a beefier source for it to sound to its full potential. As a KZ IEM, the PR1 HIFI is almost perfect overall, it just needs that ZES cable, AS16 Pro packaging, a hard case, and a cable winder for it to be the “complete KZ package” for its price. Highly recommended KZ IEM, but as always, try it yourself first and judge to see where it takes you!

Pairing recommendation/s:

• Source: The KZ PR1 HIFI needs at least 2vrms of power to sound to its full potential. I recommend using warm or neutral sounding dac/dongles to pair best.
• Eartips: The eartips included are more than fine for most use-case scenarios. However, any preferred eartip of yours won’t hurt. I recommend KBEAR 07 eartips or stock Tanchjim Zero eartips for best comfort and sound improvement.
• Cable: Cable is fine and usable for the most part, but you may always change the cable to your liking.

Sound?

The PR1 is a mild V-shaped IEM with a good amount of Bass both Mid and Sub are slightly boosted. the Bass has good weight and texture as well as good control. Moving to the Mids they have that typical recessions V-shaped have but the Mids themselves are pretty decent they sounded rich and full, vocals are a little forward.
Treble is well extended and has good details and sparkle, the PR1 is balanced with Bright tendencies.

The soundstage is open and wide it has very good details and above average separation and accuracy.

Conclusion. The PR1 hifi is an entry level planar IEM that is fun sounding, it has both brightness and good details while still being a V-shaped in ear. I found it pleasant and not harsh on most recordings.
