Kinera ThorKing Review 

Intro 

Hello, this review and feature covers the latest flagship level hybrid iem from the renowned audio brand Kinera named the Kinera Thorking ($2,499). The Thorking is actually a 1DD + 6BA + 4EST tribrid iem using the best drivers and materials. Also, the ThorKing is the latest from Kinera’s higher-end series called “Kinera Imperial”. They’ve released a number of very well praised iems from the Kinera Imperial branding which has always garnered much curiosity from the community. I’ve actually had the ThorKing in my possession for right around 10 days now and I have both Kinera and Audio Geeks USA Tour to thank for that. To both parties I say… thank you! 

Kinera

Kinera is one of those brands which I am always intrigued by. The amount of effort, craftsmanship, artistic ability, and know-how that it takes to craft some of their products can only be accomplished by some of the best in the business. The sheer amount of time and resources which goes into every last iem and audio product from Kinera is likely staggering. Especially when we are considering their flagship level iem from their high-end line. The true test of the character of Kinera and their sub-brands (QOA, Celest) is the effort they put into even their budget lineup. The same R&D and effort to maximize price to performance goes into even their less expensive iems as well. However, after spending time with it, the ThorKing is a true testament to their ability. Across the board this is a set meant to impress. I’ve seen the other brands’ best effort and there are some amazing iems and audio devices. No doubt about it. Be that as it may, Kinera sees what those other brands are doing too. This is where I envision them quietly gathering themselves and with a half-smile, they say… “Hold My Beer”. In comes the ThorKing. 

Themes

I’ve praised this brand up and down with their use of themes to both differentiate and describe their products. What do I mean when I say that? Glad you asked. So, Kinera, QOA, & Celest all use themes to craft and create their products too. Every one of them (that I know of). From budget to kilo-buck each product gets assigned a premise, a concept, or a persona, usually a mythical character from Chinese lore. Each persona obviously has its own idiosyncratic traits and qualities, characteristics. Kinera will take those traits and design a theme with which they build, they design, they accessorize, and they tune each respective product too. It is a genius method to draw inspiration from. In the case of the ThorKing Kinera decided to draw that inspiration from one of the most well-known and notable characters from ancient mythology in the god of thunder… Thor.

Thor

Many of you already know that Thor is revered as the god of thunder who wields his mighty hammer. The ThorKing actually draws from Norse Mythology showcasing the epic battle between Thor and Jörmungandr for Asgard. I will cover this later but the entire design as well as the tuning surely does evoke the sort of majestic and stoic attributes which one would expect for such a character as Thor. Once again Kinera puts on a masterclass of concept creation, development, and craftsmanship. The proof is in the end product. Great job Kinera! 

Well friends, I’ve had a blast thus far with the ThorKing and I will have to send this lovely piece of art on its way to the next reviewer. However, not till I’ve spent the full amount of time I am allotted. This is a joy for me, friends. Let’s get into it. So, without further ado, the Kinera ThorKing.

*Quick Note: I need to explain that this is not a full review of the Kinera ThorKing as I do not have the packaging or any of the contents of that packaging other than the earphones themselves, the cable, and the carrying case. This unit was provided by the Audio Geeks USA Tour and so I don’t always get the entire package. So, all I can speak on is what I have in my hands.

Accessories 

*Note: Once again, I do not have all of the accessories, or the original box which comes with the ThorKing. I am sorry for that. I will speak on the accessories that I do have. 

Carrying Case 

With a flagship level iem you should expect flagship level accessories. I can tell you straight up that the carrying case fits the bill. The case provided is actually a round black zipper case which looks stunning. Kinera opted to go with black leather along with some of the coolest texture. To add to that, the zipper is gold in color which contrasts beautifully with the black of the leather. I find the case to be plenty large enough to hold the ThorKing earphones, the cable, as well as some eartips and possibly a small dongle dac. I really don’t ever use carrying cases but if I owned this set, I would certainly use this one. 

Cable 

This brings us to the beautifully dope looking cable that Kinera provides. I love a good cable folks and Kinera absolutely nailed this pairing in my opinion. I personally feel that nobody should have to cable swap with this set. Of course, I know that half of you will anyways. However, the cable provided is primarily covered black fabric yet with some white stripes. It’s a 2-pin, 26 awg, with 7N OCC (Ohno Continuous Cast) cable made in a Litz structure with SoftFlex PVC as the outer layer. The ThorKing only comes with a 4.4 balanced jack. Of course, that’s fine with me as I really only listen with 4.4 balanced. No doubt about it, the cable provided really does sound quite awesome with the ThorKing. I know this because I tried many other cables simply out of curiosity. Kinera did a wonderful job with this one folks. 

Build / Design / Internals / Fit 

Build Quality 

I have to tell you all, I was absolutely blown-away by the build and design structure of this set of earphones. Friends, they are so well made that I’m having a hard time coming up with appropriate descriptors. The acoustic cavities are actually made using cupronickel cavity which is actually very functional towards the tuning of the ThorKing as it suppresses I eternal vibrations. However, to fit this inside of the Shells Kinera had to do some slick engineering. The Shells are actually made entirely out of brass and copper nickel alloy which is also known as “white copper” in many industries. I cannot begin to stress to you how awesome these shells are folks. I haven’t even gotten to the faceplates. The faceplate design is made out of an extremely difficult metal to work with as it is all nickel alloy. Kinera actually had to go to the extent of electrodeposition to form the intricate design of the faceplates. Kinera then had them sandblasted with what I assume is a very fine grit sand to provide such a smooth and beautiful texture. Truly excellent, fit for a true flagship level iem. 

Design

This brings us to the design of the ThorKing. Now, the ThorKing comes in a matte silver colored brass colorway for the Shells while the beautiful nickel faceplates are a high-polished silver color. As you can see from the pictures, the faceplates are actually inlaid into the shells just past flush. The overall aesthetic is through the roof folks. I cannot praise Kinera enough for what they’ve accomplished. The skill level that it takes to form the Intricate faceplate design only comes from a seasoned veteran of the process. I’d say that the crown jewel of the design is obviously the faceplates which are designed to almost look like a coat-of-arms, very regal looking, extremely sophisticated, and totally majestic in appearance. The Interwoven fines twist and turns are so exact and polished to a high shine. If any of you wonders why the ThorKing is priced so high; look no further than the skilled artisans and the painstaking process of crafting this design. Just wow. 

Internals 

As I said earlier the Kinera Imperial ThorKing comes equipped with a total of eleven drivers to create the sound that Kinera was shooting for with this epic iem. To be exact, Kinera used a four-way electronic crossover as well as physical crossover. Furthermore, Kinera crafted advanced acoustic chambers to manage the sound. Now, as far as the drivers, Kinera went with a 10mm high-polymer composite dynamic driver to handle the low-end. The driver actually sits inside of a 3D-printed enclosure to help with both pressure and volume. Truly an awesome driver. Taking care of the midrange frequencies are two Knowles balanced armature drivers. Next, the highs are taken care of by using an array of four Knowles balanced armature drivers. These high frequency drivers use Kinera’s Gemini acoustic duct to improve reverb and clarity. Lastly, the upper treble is handled by four Sonion EST (Electrostatic). We all know that Sonion typically makes the best EST drivers. I should also add that the ThorKing actually has a high-density copper-nickel alloy shell. This mixture of material is great at suppressing unwanted vibrations, resonances, less distortion, and minimized sound reflections of all kinds. Now that you’ve read that, think of the R&D that went into finding the perfect mix of drivers, shell materials, and positioning etc. There’s a reason that the ThorKing is a flagship set. 

Fit / Comfort 

Now, as far as fit and comfort, the ThorKing actually took me a minute to get a seal. I certainly had to go through quite a few eartips to find the tips which worked for me. There was a lot of fidgeting to get the ThorKing to sit right. That said, once they got in there, I was good to go. Honestly, it’s the most minor complaint and I hardly even recognized it during my time with this set. Still, the ThorKing is pretty comfortable with great weight distribution. 

Drivability & Pairings 

Sensitivity 

So, the Kinera ThorKing is rated with a pretty low impedance of about 10 ohms as well as a sensitivity of about 105 db’s. Friends, I’m going to make this brief because it’s a simple concept. Yes, the ThorKing is sensitive and can be brought to volume with weak sources. I used many different super weak devices, and they all played the ThorKing just fine. Now, erase from your memory that I ever said that because this is a set which wants and yearns for power. Folks, nobody purchases a $2.5k IEM if all they have is a smartphone to listen to it with. That’s not going to happen. Nobody decides to drop that much money with a simple 3.5 single ended dongle dac. I wouldn’t think so. Will the ThorKing play to a loud volume with a simple 3.5 single ended connection on a smartphone? The answer is yes. Should you attach this wonderful set to a 3.5 single ended port in a smartphone? Absolutely not. 

Power

Give this set the credit it deserves and the source it deserves. I can tell you that through weaker sources many of the included drivers really don’t wake up. The bass is flabbier, less defined, and the stage is narrow and less massive. Oh, and the treble is splashy on weaker sources. I made the mistake of trying weak sources first (something I always do) and the sound was not impressive as it should be for that cost. I thought, “No way am I reviewing this set if this is what it sounds like”. Of course, I never stop there, I’ll always try every source at my disposal, but the thought certainly crossed my mind. So, imagine how amazed/relieved I was when I attached the ThorKing to a proper dac/amp, dap, or dongle dac. Totally different set folks. 

Source Pairings 

Let’s just get one thing straight, the Kinera Thorking has very much a neutral-balanced tonal coloration and this is one set which thrives off of a warmer source. Anyone who has read any of my reviews knows that I rarely preach tonal contrast between source and iem. Usually, I’m okay with just about every tonal character of most sources unless they are drastically exaggerated cold or warm. However, the ThorKing really does come to its best sonic ability when it’s paired with either a warm source, or a warm/neutral source. It has to be in that range, in my humble opinion. Now, I used the ThorKing with sources which are closer to neutral, and it sounded very good as well. However, you don’t get quite enough warmth or body in the low-mids all the time. So, I don’t want to worry you if what you have is an awesome neutral source. It still sounds great. Nevertheless, warm to warm/neutral is where it’s at with this set. 

Sound Impressions 

*Note: before I dive deep into the sound of the ThorKing, I first want to express a few small things. First off, I couldn’t burn this set in as it has already made its rounds amongst many reviewers prior to making its way to me. So, I don’t know if Burn-in helps. I imagine it may. Next, I do almost all of my critical listening from flac or better files (some MP3’s) which are stored on the SD card of my devices. I used KBear 07 eartips as well. I found the 07’s to be the most comfortable and does well to add some crisp low-end punch. Lastly, the Android music player of my choice is mainly UAPP (USB Audio Player Pro), Hiby Player, and sometimes the Eddict Player. Some of my devices use either the HibyOS or Shanling’s OS as well. 

What’s it sound like? 

I love the way Kinera went about this type of signature. So, to my ears the ThorKing really represents an almost perfect reference-neutral signature with a definite tilt towards treble clarity. Actually, this set almost comes across as dead flat, yet with plenty of controlled and harnessed energy and macro-dynamic expression. In truth, the ThorKing is a top shelf set (my opinion) when it comes to transparency, separation, detail retrieval, and a top shelf stage size. The Thorking comes across with almost what I’d call a dead neutral take on the spectrum and one of the cleaner sounding sets that I’ve heard. This cleanliness opens up the mix and offers a multi-layered soundscape with a very airy and open feel to my music.

Clean & Transparent

One aspect of the ThorKing’s tuning is its ability to sound both brilliant and shimmery, while never truly sounding fatiguing. Much of that luster comes directly from the well composed highs. I actually have a lot to say about the treble, but more on that later. I think one of the real draws of this set is just how clean and crystalline it can sound. In fact, I’d be willing to call it the pinnacle of cleanliness. You’ll hear the words; clean, transparent, balanced, layered, airy, and detailed a lot in this review folks. It’ll be hard to get around that. Just preparing you. What does it take to get a sound that is so well pristine and so abundant in controlled-clean energy? Well, have you looked at the ThorKing’s graph? Friends, there is no masking of any kind, no frequency fighting for dominance, no mudd whatsoever, and veil is a thing that the ThorKing laughs at. Without question, this is a set which had to have taken a very long time to craft with vast amounts of R&D and a lot of expertise to get the result which is in my ears as I write this. That said, the ThorKing may be a hair polarizing… 

 Polarizing? 

The Kinera Thorking is one of those sets which surprised my senses upon first listening. I just got done reviewing some warmer sets and along comes this expertly crisp and completely neutral take on my music. I loved the sound from the jump folks. Granted, it is also a sound that I had to be a bit more selective with which genres I try to enjoy. Basically, the ThorKing is not exactly an all-rounder. Having said that, it is ridiculously wonderful for what it was tuned to be. With that thought in mind, please understand that this set will not be for everyone. I think that’s kind of how it goes past a certain dollar amount sometimes. You start to see sets which are geared more toward a particular style, per particular genres, and sets which favor certain types of consumers. Sets which are more focused towards a certain blend of sound and they specialize in that tuning. Which is great. I mean, you are spending that much money so you might as well purchase something which fits your preferences. Without question the ThorKing will be somewhat polarizing due to its neutral-balanced-flat-transparent signature. Essentially, those seeking a fun signature, a bass driven and bombastic signature, or even warm, rich, and musicality-first signature may want to go a different route. 

Enchanting

What you’ll get with the ThorKing is a set which will resolve every last detail, even in complicated tracks (which is wild). You’ll get fantastic air and openness, leading to very nice note separation, spot-on imaging capabilities, and a sound field which comes across wide, tall and deep. The Thorking features a multi-layered and holographic stage that is definitely immersive and honestly… enchanting to my ears. Without a doubt the ThorKing is an analytical style sound with brighter hues, a dryer atmosphere, and without the robust and warm/weighted energh that some sets will have. However, that is hardly an issue for this set. Because what the ThorKing excels at is done in a masterful way. Crystal clear, transients which stop & go on a dime, textures are everywhere, black background, and all the bite, lean-punch, and crispness that you’d ever want out of an iem. Now, timbre is not exactly the most natural that I’ve ever heard as the note weight is closer to lean in note body along with a brighter top end. You simply don’t have the warmth necessary for a richer and more organic sound. In the same breath I also wouldn’t say that the ThorKing is completely artificial sounding either. Perhaps just a hair too precise & too transient tight to be considered traditionally “natural”. I have zero issues with that. Once again, this set is crystal clear folks and wholly melodic in its own way. Sure, it’s leaner and dryer, but there is very nice note structure, with condensed and more rigid lean notes. Best of all, there isn’t anything which I would consider too harsh or too sharp. Similar to the Letshuoer Cadenza 12 yet slightly less warm. Really a very nice sounding iem for those who can appreciate it.

Genres

I should also note that not every genre is going to fit perfectly with the ThorKing. Sure it does just fine with most genres (generally), but it excels a bit more in a few particular types of music. This is my opinion based off of my playlists so take it with a grain of salt. The first category of music which seems to really do well with the ThorKing is Orchestral or Classical music. It simply provides such a clean, airy sound, and it’s detail-rich with great clarity. Also, the ThorKing handles complicated arrangements like a pro. Also, jazz seems to work out very nicely for the same reasons. Acoustic tracks sound fantastic with the ThorKing as well. Another is classic rock which also benefits from the ThorKing’s clarity, tight transients, and detail retrieval ability. I’d also say some vocal centric tracks if you don’t need that extra warmth. I personally enjoy a hair more warmth and weight but the ThorKing does a nice job at replaying crystal clear vocalists. Of course, on the other end of the coin you have genres which may not be the best with the ThorKing. Basically, anything which relies on a heavier, meatier bass like hip-hop, EDM, R&B, or any bass driven Pop tracks. Anyways, that’s just a quick 3,000 foot overview. Let’s check out each 3rd of the mix…

Bass Region 

I put this set in my ears and for some reason I was thinking I’d hear some heavy and meaty bass. I was thinking “Thor should have some bass, some muscle associated with him”. However, what I was met with was some of the highest quality bass with a below moderate emphasis. This is not a bass region which will fill out every bass guitar or carry those resonant hollow booms of a big kick drum. Instead, this is a bass which is the epitome of quality-over-quantity. In my opinion, I would best describe the ThorKing’s bass region as controlled and refined, a hair cold, but defined, effortlessly agile, and easily able to cleanly outline every note of a complicated track. This is obviously not going to be the type of bass that any bass-boi would enjoy. In fact, even moderate bass lovers will likely not completely love the actual emphasis. However, the ThorKing will absolutely rise to the occasion when a track displays some deeper or heavier bass lines. It just won’t be to basshead levels. Let’s put it this way; the bass will absolutely never cloud the mix. Actually, the ThorKing is not without some dense punch. No, it isn’t the most authoritative or bullish punch, but it is punchy, with the speed akin to a fast twitch muscle reflex and a sublevel response that will show up when needed. 

Blur-free, Mud-free, Veil-free… 

I love good bass. It’s always the very first thing that I test and always the first area of the mix which captures my attention. Now, the bass in the ThorKing didn’t give me some awe-inspiring moment of unhinged gratification, and I wasn’t completely enamored at first. This one took some time folks. No doubt I could easily hear the fast reflex transients and amazing detail retrieval across the rest of the mix right away, but the bass took a moment or two for me to truly appreciate. I think it was the moment that I put on “Muse” by Hysteria which caught my attention along with some other faster and more elaborate and more intricately layered bass tracks that I realized how this measured bass fits into the overall target that Kinera was shooting for. Folks, the tuning is purely awesome and the way the bass acts as a supporting actor is quite nice. Of course, there will be plenty who wouldn’t dare purchase a set with such a flat bass shelf, but you’d be very surprised how the ThorKing’s low-end timbre, along with its fantastic note separation, and layered approach opens up the region and thus opens up the rest of the frequency. This is a blur-free, mud-free, and veil-free bass folks. 

Sub-Bass 

Now, the sub-bass is the area that I feel owns the brunt of the emphasis within the Kinera ThorKing’s bass region. Granted, it takes the ears of an elephant to hear the difference in emphasis between the two brother regions. Still, the sub-bass certainly has what I’d call just enough depth, and ability to create a mildly juddering sublevel response. If I’m being honest, it’s not super easy to hear the impact of the sub-bass when a track doesn’t have representation of this region. However, when I hear a track which does offer that guttural response I am very nicely surprised at how the ThorKing displays those deep notes. Tracks like “Tell Me What’s on Your Mind” by The Decemberists is one such track as the electric bass in this song is the literal foundation of the track which grooves on in a wavy bullish way while the melancholic melody dances around it. Trust me, if the ThorKing can’t step up to this track then we have some serious problems. Thankfully, it does more than just step up folks, it sounds amazing. I am so taken with how well separated the deep bass is with the rest of the mix. The spacing, the layers, the density of notes, it all just sounds great. However, don’t expect the sub-bass to sound anywhere near a more emphasized set. Just around moderate to my ears, but of very high quality. 

Mid-Bass 

The mid-bass follows the same line when it comes to its overall weight and emphasis in this region. I found that the mid-bass truly excels at providing a very texturized and tactile feel to the sound with completely unsullied notes along with some of the best clarity that I’ve heard in this region, on any set. Now, as I’ve already stated, the ThorKing is not what I’d call a fun bass. At roughly 3db’s of bass shelf this has more of a reference and linear sound, with precision, definition, and surface texture as its saving grace. The mid-bass focuses on clarity rather than impact and slam. It is not my favorite by any means as I do enjoy more of an earthy slam and boom from time to time. But I can’t help but be impressed by how well the mid-bass collects every inflection from the bass guitar riff as every pluck and slide of the finger is caught in a lifelike manner whilst keeping perfect cohesion with the mids and treble. Once again, the beauty of this bass is in how seamlessly it fits into the overall scheme. This DD matches the speed, cadence, and clean edge spirit of the other drivers perfectly. Again, it’s ridiculously fast, expertly agile, and one of the most dexterous mid-bass displays that I’ve heard in a while. However, of course this will not be for everyone. You really have to appreciate the sound for what it is and for the genres it was meant to specialize in. 

Downsides to the Bass Region 

I think we all know what the issues are here. The bass is definitely on the thin side. This is not a bass which makes its presence felt in a way that some hobbyists may enjoy. Some may consider the emphasis itself to be an issue. I completely disagree, but to each their own. I suppose I’ve had the luxury of getting the time to learn to appreciate Kinera’s goals for this low-end. That said, let’s face it, the ThorKing’s bass region really doesn’t carry that robust and sonorous mass that can produce a heavy impact. Now, it does have texture for days and is lightning fast, but it won’t be thought of as the most fun bass any of us have ever heard. Still, I think Kinera was able to tune this region per the target that they were going for, and they did so in a very compelling way. 

Midrange

The midrange also fits the overall scheme very well too. Now, I know I called the general note weight as lean. However, this isn’t a “lean” which sounds frail or weak. This is one thing which stuck out to me actually. In fact, there is most definitely a certain dense and rigid structure to notes provided from the clean resolution and dynamics of every note. That said, the midrange is also basically an uncolored and non-boosted affair with very little if any bass support to bolster this region. It’s crystal clear and carries a very clean sound with razors edge transients and perfect note contours, but it’s not warmly rendered. This is not a midrange which I would refer to as rich. Is this a problem for you? Speaking for myself, I love all signatures. I can enjoy them all. As for the ThorKing, I adore how it feels like every note seems almost suspended in its own pocket of air with that neutral clean timbre. Somehow, a tuning which I’d never refer to as musical on paper actually comes across very melodic. Especially for classical, instrumental, even jazz. The midrange plays the biggest part in that statement. The clarity, the speckless note outlines, the tight yet not clipped decay, the resounding nature within the atmosphere and the holographic dimensionality of the sound is wonderful. However, you have to be able to appreciate it, friends. 

Elegance

Another aspect of this midrange that is pretty great is that it actually has some very nice timbre. Sure, it isn’t glossy, warm, rich, and organic, but it is sensational in its accuracy, its lucidity, with its non-offensive, ethereal, and dry-matte style. It has none of the hangups that many balanced armature drivers can have when they aren’t accompanied by ample amounts of warmth. Stuff like “BA Timbre” or “Metallic Timbre”. I find that these drivers do a remarkable job at creating what I’d call a neutral-natural sound. No haze, no blur, no veil, and there’s none of the grain and note fuzz which so many sets have. Everything is crystalline folks. Furthermore, the detail retrieval is simply outstanding. Now, the mids aren’t what I’d call “immersive” per say, but engaging in a very distinct and pure way. There’s an elegance to the sound, oddly enough. Again, you don’t have any of the metallic annoying timbre and I hear zero sibilance. The way these drivers portray this region is more in line with studio precision, yet without lacking the mellifluous cadence of a pleasing sound. Having said that, this is an almost entirely analytical take on the spectrum. I have to admit that I would usually not reach for an analytical-first iem over some others in my collection. Which is what makes this set sort-of like a unicorn for me because it really does sound good and the midrange plays a giant role in that. 

Lower-Midrange 

The lower midrange is the place where most males reside. Typically, it’s male vocalists which take on this region. Also “typically” I have much more of a desire to hear robust, weighted, full, and authoritative male voices. Without question this is the biggest hangup for me concerning the ThorKing. Having said that, males don’t sound bad by any stretch of the imagination. There’s something about clarity which can almost emboss vocals. You see, the ThorKing has a black background paired with a quick decay and zero of those lingering harmonics, resonances, etc. which blend and mash notes together. Ultimately those notes simply sound more dense and more substantial, even in the leaner structure. I do hear a faint recession as well. However, even with the slight recession in this region, vocals still have the psycho-acoustic perception of sounding embossed. Notes have presence with a very outward vibrance. To say it another way, male vocalists come across leaner, less moistened and less robust as they simply don’t have the low-end’s smooth warmth, but they do have some prominence within the sound field created from clarity alone. Having said that, I completely understand anyone who adores a warmer, richer sound not totally in love with the sound in the ThorKing’s low-mids, but man are they clean. 

Upper-Midrange 

The first thing I’d say about the upper-mids is that they are more forward (by a slight degree) than the low-mids. More out in front. The upper-mids come with more shimmer, more sparkle, but they are also pretty smooth in texture. Most certainly you get some brighter hues from this region, but never did I feel that the upper mids caused my ears grief. This is not a shouty set. How Kinera managed that is beyond me as there is no real warmth to counter the upper end emphasis. The truth is, the upper mids simply sound pleasant in respect to the tuning. Also, the upper-mids have zero masking happening which keeps them crystal clear, and just prominent enough. Excellent transparency, top tier articulation, and precise note definition is a mainstay of this region without the abrasiveness and knife-edged crispness which usually accompanies a more illuminated upper midrange. Now, female vocalists actually have a pretty natural sound, albeit leaning bright, and with solid air to their vocals. Vocalists like Olivia Rodrigo in the track “Enough for You” showcases this (along with every other track) as her voice has an uplifted inflection, more vibrant in tone, yet never to a fault. Or Adele in “Hello” in which the ThorKing wraps her voice in openness and provides just enough smooth rendering to cut down on some of her more edgy moments. She really does sound fantastic. Every breath is captured, every lip smack and every subtle harmonic sounds accounted for and discernible. 

Instruments 

As far as instrumentation goes, the ThorKing will either nail it, or sound a hair too lean/dry. Let me just say that for the most part instruments sound lifelike, in general. It isn’t the tone which causes any subtle issues, it’s the weight. In my opinion. Still, for the most part, the ThorKing renders instruments very well within the midrange. Like piano which usually comes across with that nice clean ambience, while its timbre, attack, & decay sound clean along with a very nice sparkle which works nicely. Strings also come across lifelike. Violins for example have great string accentuation, nice floating harmonics (albeit somewhat clipped at times), along with great clarity and unsullied separation within the mix. Acoustic guitar is another which benefits in the same way. The details come through fantastically clear, every finger slide, that light abrasive edge, the euphonious subtle hollow resonance hums without any warmth blending sounds or masking. Percussion has a very nice snap, a nice crunch, and comes through crystal clear (always), but perhaps some drums could use a hair more body. Still very clean. Woodwinds also generally sound engaging and airy. However, these are just some highlights folks. No doubt there are plenty of instruments which require a bit more body and a warm tonal color to sound organic and natural. 

Downsides to the Midrange 

If I would speak on any issues of this region that affects my listening experience the most, I’d probably say that the ThorKing subtly lacks that visceral, weighted body to notes and could use some warm tone-color which would provide some organic fullness. This goes for some richer sounding male vocalists, stuff like cello, electric guitar, electric bass guitar, kick drums, etc. Really, any instrument or voice where body/weight defines some of the character of that instrument or voice… will at times feel lacking and not stand out as well. I could also say that the ThorKing may simply be a bit too bright in the upper mids/lower treble regions for some hobbyists. However, I assume that the people still reading this are more in line with the sound. Those folks didn’t even make it past the “Bass Region” section. Nobody is spending $2.5k on a set that doesn’t align with them. That said, anyone who desires that extra richness created from warmth will not necessarily find that here. Instead of richness, the ThorKing’s midrange has presence. That presence is created from its clarity, note definition, cleanliness, note rigidity, excellent layering abilities, as well as its fine dimensionality and holographic stage. Honestly, I am impressed with the ThorKing folks. Of course, I also know what genres and tracks will reciprocate its tuning style in a way that I enjoy too. 

Treble Region 

This brings us to the treble region of the Kinera ThorKing. An area where I couldn’t help but be impressed. What I enjoy about the treble response is that like every other area of the mix there’s plenty of controlled energy, crispness, and this ever-present smooth cadence which never sounds abrasive. Prior to hearing and after I first peered at the graph, I thought for sure the ThorKing was going to be a peaky and piercing brilliance-fest. What I encountered was totally different. Not that it isn’t brilliant, but it isn’t peaky, isn’t harsh, and is always under control. In my opinion, the treble is akin to a treble head’s dream. I mean… perfect treble contours, natural-ish timbre, wonderfully controlled vibrance, great extension into the highest of highs (upper treble), and all the bite, snap, crunch, and punch that a person could ask for in this region. The smoothness that I mentioned is very nice to the ear yet there’s a very clean and crisp delivery which defines and etches around notes within that smoother cadence. It’s lovely. The treble generally carries a natural attack and a slightly tighter than natural decay. The highs really don’t have any clipped harmonics either, which is also very nice to hear. Again, it comes across more naturally than anything else. Perhaps a touch tighter and crisper than natural. At any rate, without question the most emphasized and prominent area of the mix rests in the treble region. This emphasis adds such a vividness, lucidity, and luminance across the mix but really adds sparkle, a clean edge, and snap to the Midrange. It’s an uplifting and immersive treble and it really does play the role well of the “best frequency” on one of the “best analytical-first iems”. 

Quite nice! 

Remember, the treble region is covered by eight drivers in total. That’s four Knowles BA’s for the lower to mid treble and four Sonion EST drivers which finish out the upper treble extension and air. Folks, the tuning is simply awesome. If you haven’t heard a stellar treble before, friends… look no further. The ThorKing’s highs are easily one of its bright spots. I said that it’s the best frequency on one of the best analytical-first iems and I mostly agree with myself on that. What I 100% agree with myself on is that this is a stellar treble region and one that treble heads could truly adore. I love the crisp bite, that note defining edge detail of every note nicely carved into the sound field. Also, that nice treble punch. That quick-dynamic treble thrust when a track calls for it. Yet this bite, this punch, and this clean-edge sound outlines, renders, & contours treble notes within a wave-like and smooth overall treble demeanor. It’s quite nice. I can hear the EST drivers at work and the Knowles BA’s mix with the midrange in a very nice cohesive way as it all comes together without issue. 

Extension 

Like I said, extension into the upper treble is well done. This upper treble representation certainly provides an airier and more open feel to this set along with plenty of sparkle, some shimmer, and just a touch of radiance to insert some energy, some dynamic flare, some luminance, and some crispness into my music. Of course, this is also the region where upper end overtones add quite a bit of great information from many different instruments. Like, hearing the secondary harmonics of a cymbal strike in such a way that we don’t hear any smearing or splash. It’s a smoother take on cymbals for sure. I hear very elegant subtle overtones from many instruments including high woodwinds like piccolo & flute. Or percussive instruments like the triangle, and even upper register female vocals etc. The list goes on. The point is that most upper treble instruments sound substantial and very clear. Really, I hear a very mature sounding mid treble to air region with a master’s touch of excitement cresting the notes of this region. What this “air” provides is room for instrument / note separation frequency-wide. It provides space for notes to breathe, to sound distinct, and to sound contoured. This airiness also stretches the stage to an extent, or it gives off the psycho-acoustic perception of a wider and more massive stage. Folks, I feel like I can see the space around the stage as the cymbals sparkle, the violin cries and other instruments give reverberant life and spatial reflections to this region. Certainly, a good thing to those who can enjoy this style of tuning. 

Downsides to the Treble Region 

So, yes, the ThorKing has one of the better treble presentations that I’ve heard in a while, but with that type of treble tuning also comes some subjective issues that some folks will have. First off, the treble clarity is great, but that clarity will also expose any bright or harsh peaks within your music. Basically, the ThorKing reveals any sizzle, tsss, or sibilance within a track which is recorded that way. Or any hot electric guitar riff screaming across the treble region. The Thorking can definitely highlight some of that razor-sharp edginess. I realize that this is to be expected and really isn’t something that I consider to be a true “con”, but it’s a “downside” for somebody. Another thing to be mindful of is that not every source can truly bring out the best in this treble. Granted, most any device with adequate clean power will usually do the trick. Nevertheless, weaker sources can sound splashier to my ears. Just something to consider. Lastly, and probably most important, the treble emphasis is not going to be for every hobbyist. It will be too radiant, brilliant, and bright for some folks. I happen to find the treble meshes very well with the rest of the mix and I don’t fine the treble to be too bright. Of course, I can enjoy brighter sets too. However, just as I said earlier in this review; the ThorKing will not be for everyone. Especially those who enjoy a less refulgent, or even darker treble. Again, just some things to consider. 

Technicalities 

Soundstage 

One of the major key benefits of the ThorKing’s tuning is definitely its stage size. However, it isn’t just the size which makes this stage impressive for me. No doubt the width is fantastic with a perceived stage which stretches beyond my ears laterally. This brings on a sense of separation, of space, and of openness. Also, the height fills out my head space with a very nice vertical size. Lastly, depth of field is very evident as the front to back projection of instruments and vocalists really does provide this sound field with a multi-layered and holographic experience. The ThorKing executes strong spatial cues which is only helped by its equally strong note separation and stellar imaging. The Thorking is the furthest thing from cramped & congested, and the combination of its wide and spacious sound, its tall and open height, as well as its relatively deep sound field brings on a true sense of 3D dimensionality. The soundstage is a certain “Pro”. 

Separation / Imaging 

I don’t think you have to wonder what I’m going to say here as this entire review I’ve been boasting about the ThorKing’s ability to create space with very distinct and cleanly contoured notes along with very precise note definition. Add in the fact that the ThorKing has those tight transients, black background, open and airy stage, its lean note body, clarity, and crystalline sound. Add all of that up and you’ll have a surefire highly technical set which can create clean space. So yes, the ThorKing has great instrument separation. As you might have guessed the ThorKing also has top shelf imaging capabilities too. For all the same reasons that the ThorKing can separate and create well-articulated individual notes is the same reason that it does imaging well. Every instrument has its place, never floating around my head (unless the track is recorded that way), and every note carries good dynamism no matter where it is within the sound field. I’ve also said a bunch of times that the ThorKing has what I’d call a “multi-layered” sound. Whether left, right, foreground (anterior), background (posterior), or even from top to bottom; the ThorKing is able to stack these sounds, partition these sounds, and do so even with complicated tracks. They don’t call it the King for nothing. 

Detail Retrieval 

Okay, now I just sound like a broken record at this point of the review. Friends, the ThorKing’s ability to illuminate the subtleties within my music is very strong. It stands to reason to because the tuning is quite literally meant to do just that. It has that perfect recipe for the intricacies, finer elements, and nuanced micro-dynamics to be brought to the surface. I could go down the list of all the quality attributes that the ThorKing was gifted with, as I did in the “Separation/Imaging” section, but I think you get the gist. Folks, the detail retrieval is so nice and well separated, dispersed across the sound field, and distinct that you’ll likely catch yourself listening to minute details in focused places throughout the sound field at times rather than simply listening to your music. I know many people in the community who deeply desire that DETAIL BEAST of a set which can easily draw out details and the ThorKing may just be an endgame for those people. 

Final thoughts on the Kinera Thorking 

You’ve read this entire review and so you’ve likely gathered that I’m pretty darn impressed with what Kinera has created in the ThorKing. Ya know folks, the ThorKing doesn’t even carry my subjective “favorite signature”. I usually reach for a set with more warmth and a more of a musical character. I usually need a bit more low-end muscle, some more weight, some more rhythmicity, and simply a more fun signature. Bass with balance and some sparkle up top. A good mix of fun and maturity is what I enjoy. However, the Kinera ThorKing is anything but traditionally fun.

TOTL Joy!

With that thought in mind, I had loads of fun, loads of joy, and I truly can appreciate the ThorKing for what it is and for what Kinera created it to be. You see, I don’t judge anything strictly off of my preferences. I never have and I never will. I judge this set, and any set, based solely from the target tuning that each respective brand is shooting for. How else should one judge anything if not by the metrics that each set was tuned for. Basically, I’m not going to trash something just because Chris doesn’t perfectly jive with it. This isn’t about me. The Kinera ThorKing is one of those sets whose signature is not one that I’d typically go for, but I cannot tell you how many times I wanted to get home from work so that I could listen to them while I had them. The ThorKing is an extremely talented iem in many regards and my ears were witness to this every day for 14 days straight. My thoughts are this; no matter what your subjective preferences are, I don’t think that anyone could belittle this fine set with an honest pen. Whether you like it or you don’t, I don’t think anyone could honestly tell me that the ThorKing isn’t highly qualified per the tuning that Kinera intended. Truly a fine set and the epitome of luxury in earphone form. Without question, the ThorKing is fitting of a flagship iem. Of course, a flagship iem that many people will most certainly adore… if it fits your preferences. 

The Why

Why will many people adore this set? I’m glad you asked. Folks, I wasn’t able to actually review the entire packaging, but from what I can see from pictures Kinera spared no expense. The unboxing looks very nice, as always from Kinera. Then, the build quality of the Kinera ThorKing is absolutely next level. I cannot get over how beautiful this set is. The artistry, the intricacy of the faceplates, and just the overall design in general is stunning work. Great job Kinera. However, what helps this set make its mark at $2.5k is the sound quality. Folks, for an analytical-first, very clinical, even dry iem I am taken aback at how melodic the ThorKing can be. There is this level of euphoniousness and dimensionality which brings the listening experience to a new place for me. That ultra tight, precise, and fast bass takes on anything I throw at it. It never muddies the water, never veils, and always steps up to the plate with its punchy nature. Pure quality-over-quantity. The midrange is such a well-tuned version of neutral-bright with a semi-forward sound that never fatigues. The mids are airy, open, seriously well detailed, wonderful note separation, with rapid transients, crystalline clarity, and a stage which sounds multi-layered and holographic. Also, the treble is some of the best treble I’ve heard in some time. It’s sparkly, shimmery, brilliant, with great extension and is highly detailed. The treble region has that perfect bite, punch, and crispness to go with an otherwise smooth cadence. Technically, the ThorKing is right up there with some of the better sets on the market. Again, fantastic detail retrieval, spot on imaging capabilities, with a layered sound and a 3D style soundstage. Honestly, I am very impressed friends. Excellent job Kinera!
