GEEK WOLD GK20
Redcarmoose Labs January 1st, 2024
While I have the latest GEEK WOLD GK10s in route to me, they haven't made it in time for comparisons. Yet I really am curious to hear them, as somehow GEEK WOLD has started to make their lesser priced IEMs sound pretty good? While I have only heard 2 GEEK WOLD examples, both the GK100 and GK20 sound both a little the same and a little different. So to let you understand the history of GEEK WOLD…..
Sold today:
GEEK WOLD GK80 1BA + 2 Piezoelectric + 1 Dynamic Driver $46.90
GEEK WOLD GK10s 1BA + 2 Piezoelectric + 2 Dynamic Driver $49.90
GEEK WOLD GK20 3BA + 2 Piezoelectric + 2 Dynamic Driver $99.00
GEEK WOLD GK100 2BA + 4 Piezoelectric + 3DD $200.00
GEEK WOLD GK200 6BA + 2 Piezoelectric + 2DD $350.00
This takes us to the original GEEK WOLD GK10. Priced at $45.00 USD, the GK10 came out in early July of 2021. There was also a GEEK WOLD GK3 that was released in 2018, yet pretty much overlooked by the Head-Fi community. Yet the original GK10 was a success and really is the single earphone which brought GEEK WOLD to Head-Fi. For the most part (at the time) the GK10 provided a sound that for the money was untouchable……I hear.
The original GK10:
1) 8mm titanium dome dynamic bass
2) 7mm graphene dynamic for midrange
3) A BA for treble
4) And two piezoelectric for treble extension…..just to top things off.
Such an invention would compete with many IEMs in 2021 even up to $200 so I'm told?
GK10s:
I mean sure the GK10 is legendary, and most likely the GK10s will be a subtle improvement, I can guess?
The GEEK WOLD GK20:
But to take this GK20 seriously, I probably like the bass better than the double the money GK100? And even though I have only heard two GEEK WOLD products, I do understand where they are coming from…….GEEK WOLD is attempting to give the budget world a taste of high-end treble. Really that is my generalization of what their goals are……..as such I can only guess their start here at Head-Fi (with the GK10) was based on that same premise? GEEK WOLD is putting a lot of parts under the hood.
GEEK WOLD GK80 4 drivers $46.90
GEEK WOLD GK10s 5 drivers $49.90
GEEK WOLD GK20 7 drivers $99.00
GEEK WOLD GK100 9 drivers $200.00
GEEK WOLD GK200 10 drivers $350.00
Now to level with you, I really think the GK100 is on the larger side of big. I have seen pictures and laughably the (huge) GK200 dwarfs it……..so? Sure you want the GK200 10 drivers and are willing to put-up with that specific size, fine then, also that size difference looks to be mostly the added thickness over what the GK100 example is, as seen side-by-side in photos. Yet as little as I know about GEEK WOLD’s line up, this GK20 is a whole new deal, a whole new way of making an IEM. Notice when you see both the GK100 and GK20 (side-by-side) in my photographs, you can start to realize that GEEK WOLD took a whole new approach to making the GK20. Yep, it is solid 3D printed resin, where the GK100 is a hollow shell. And while the GK20 is 5 grams and the GK100 6 grams, the GK20 is see-through and the GK100 a totally opaque hollow shell. But more than that, the GK20 has way more curves to help it sit inside your ear farther. And finally the GK20 is truly a medium-small size………and for some that is going to be a big deal. So custom universal 3D designed and smaller (for me) better fitting than the GK100 form-factor.
How do the GK100 and GK20 compare sound wise?
First off the GK100 takes slightly more juice to get it going. And bass is actually more substantial with how the GK100 portrays a song. With that said (and if you read my GK100 review) the mids are a tad dry, or not as fully worked-out to portray vocal life in general, even compared to the GK20. What I’m trying to say is the vocals are forward and holding placement, it is just that the actual tone is on the dry side. Now I hope you understand this is not as big of a deal as it seems. Why? Well this giant groovy bass action and size of stage, makes the GK100 incredibly fun anyways. The fact that it is the ultimate Hybrid being built with no less than 9 drivers, using Piezoelectric, BA and DD to function. Where the GK20 goes ahead and adds a pure flavor of moving more upfront imaging and the vocals follow along to become showcased ever so slightly better. Just ever so slightly cleaner and more natural.
Heck, I can see the owner of GEEK WOLD sitting in the boardroom and having a discussion with the sound engineers. He is saying make me a new IEM and make it smaller, make it have more upfront and personal vocals……you don’t have to make these changes too different in the vocal department except maybe 20% or 28% of naturalness will make a world of difference to our consumers. This change is adding slight note-weight to the GK20 vocals and somehow that adds reverberation comprehension? Heck……what am I talking about? The vocals are simply clearer……that’s all. Now keep in mind that if you already owned the GK100 and primarily listened to instrumentals…..stay with your GK100. The GK100 increased separation and itemization is a real thing, over the slightly more together (forward) stage and item placement found in the GK20.
The truth is the GEEK WOLD GK100 has a smoother and more sophisticated instrument generation, especially up-top. Stuff is found into better detail and of more resolution, more lifelike even, falling into a better arranged and more realistic placement. So yes, you can tell it is the more expensive IEM, only the GK20 has better vocals……..more lifelike vocals!
The trebles GK100 v GK20:
I’m not one to concentrate on treble, I’m more into midrange and bass, yet I know trebles are super important to many, and maybe more so if a person is curious about a possible GEEK WOLD product? I’m partially guessing that this brand is trying to bring an expensive and sophisticated treble response to the value market, I mean there is room for such focus out there. And sure enough that is what is going on, all this complete itemization and structuring of separated treble components. The shakers, the hi-hats, the cymbals…..and those sounds that are indistinguishable as to what they truly are, but reside way up there in the treble response regions. To level with you, the GK100 does those better, and not just the sounding clearer, but even the reverberations of the treble items…….the GK100 room response is found to be more complete, clearer and better separated. Yet, if you truly wanted better vocals played, all of that maneuvering may matter less.
Conclusion of GK100 v GK20:
All this talk of one being better at this or that could lead someone into thinking that one IEM is faulty or off. When the truth of the matter is both IEMs lend themselves to very balanced and thoroughly entertaining replay……..as if you were strictly into instrumentals and listen to vocal music secondary…then the GK100 would be the way to go. If you wanted airy and forward vocals which contain an element of a breathy human character…..then the GK20 would be your choice.
The GK20 v the MEAOES Eagle:
I reviewed the MEAOES Eagle almost exactly a year ago on January 5th, 2022. Coming in at $149.90 the MEAOES Eagle fits right in with our side-by-sides. I mean just look at how the shell seems to be made at the same factory as GEEK WOLD………..but more than that the Eagle is also going ahead to offer more treble details and definition same as our IEMs above. Those who have been around maybe remember HIFIBOY, well this is that brand. We are gifted here with 2BAs and 2DDs. One DD is 7.5mm and the other is 8mm.
Here I would call the Eagles personality as the hard-trier. Where there is this ultimate treble definition, yet it isn’t of the best way blended nor of correct timbre. There is this synthetic aura to the top-end yet to someone trying out $150.00 IEMs in a shop this brightness and in a way technicality could come off exciting……….at first. And even a year later I have always been pulling the MEAOES Eagle out to see how different cables may help align the sonic response into a more cohesive and toned down approach. And sure enough a few weeks ago I really hit pay dirt. Which is one of the values of cable rolling, that every once in a while you have this magic cable that can truly change things for the better. Now the other extreme here is the bass! Yep, the bass is actually quite good for what it is. But to truly put things into perspective…….the Eagle makes the GK20 look surprisingly good…….almost perfect in comparison, it’s just a fact of life that the treble with the GK20 is just way better done. Also surprisingly the vocals with the Eagle regardless of the treble were actually quite clear and forward, really very good. Still the fitment and feel of the GK20 is better as well as the outside noise occlusion which gets an increase due to fit. Though to summarize this battle, it’s the midrange and top-end timbre that the GK20 ends up doing so much better…..that and better vocals……for less money, too! It’s just that the GK20 comes off as the more cohesive and mature player…….smaller and better fitting too, sorry to say.
Build:
2 Piezoelectric ultra treble high frequency drivers
2 Treble BA drivers
1 Midrange “BIG” BA
2 Dynamic Drivers
A 3 channel, 4 frequency internal design. There is a titanium DD for the super lows, and a LCP DD on top responsible for the lows. Such 3BA-2DD-2PZT arrives at a 7 driver IEM inside a compact 3D printed shell.
Cable:
Right before I started the below music tests I went and prequalified the included cable. What that means is (the included cable) could be less than optimal to do complete listening tests if it had sound quality issues. And I was suspicious as I had spent an entire evening using the included cable on a (different) IEM. And when I switched cables to a different aftermarket cable I found the stage opened up a little. Now you may wonder as to the reason why I chose the GEEK WOLD included cable for this other new IEM? Reason being is it is 4.4mm……and a great way to access the 4.4mm amplifier in some (now maybe most) DAPs. So in the end I actually prequalified the included once more and while not the very best cable I kind know why they included it with this package. 1st off the cable has a look and feel that is spectacular. The included cable looks like money with the gorgeous trademark named 4.4mm plug. The way the ergonomics work out in daily use. The way the chin cinch works, and finally the color coded 2Pin plugs and ear-hooks. Also who knows why it wasn’t the very best with a random IEM but I came to a definitive understanding as to how the cable performs. It must have a touch of silver over the use of copper because what this cable does is accentuates the forward positioning of imaging. Meaning trying other warmer cables the effect was less contrast and while slightly smoother, did not bring out the wanted vibrancy and even vocals inherent in the character of the GK20. So in my mind I went back to the boardroom ideas of GEEK WOLD and I could hear the GEEK WOLD President saying……I want vocals with this one. Being the last GK100 had meh vocals, do me and the listening community a favor and add vocals, we don’t want the reputation of so-so vocals, especially since this is China the epicenter of vocal music. And sure enough they added a cable which helped push the vibrancy………so much that after understanding what GEEK WOLD is up to with the personality of this cable, and the fact that it came with the IEM, and the fact that it’s beautiful……..well you get the message. Besides the GK20 is so well rounded that it goes with phones and DAPs and desktops. Yet I bet GEEK WOLD included a 4.4mm plug standard as they found out the GK20 craves a good source to become its best? I mean sure you can get the GK20 a regular 3.5mm plug and hook it to your phone and the sound is full and not thin………….except there is a profound difference in regards to stage and imaging, and even a more authoritative nature arriving at your favorite DAP or desktop. So to summarize this rambling……..the cable is fine and actually has many redeeming factors in daily use, you don’t need to change, except there are other places in tone that can be found by using some GUCCI cable you have laying around…..the GK20 has the ability to go there.

This song is one of my all time favorites and it contains vocals so going with the program here. But more than that, I’m more into instrumental music except I do appreciate good vocals from time to time and understand the concept of how they are done by an IEM character. Here are female vocals, yet I tested many other examples of male vocals to learn about the vocal abilities presented here. Probably the message to this song is that the GK20 doesn’t just to vocals…..but performs in such a balance that it does it all………I mean right off….right off the bat this is what I’m hearing! At 00:16 there are forward and punchy bass actions……..where it may be a layering of both synth bass and regular bass? Or maybe it’s all synth bass…..whatever it is there is a quality to where if it cuts through, and I’m content with this demeanor. If we rewind there is a wolf-howl at the start……at only 00:12 we hear the reverberations contained in this sound effect, bringing the realization that this isn’t your parents $99.00 IEM. And while going to the very start of the song there are thunder-clap sounds…………but to generate an idea of truly the resolution here there is a faint sound at 00:12……..it may be some movement in the studio, maybe it’s supposed to represent a lightning strike here? Whatever it is…..this is what an expanded top-end is about……the small stuff…in great detail and heard. I can look over at my collection of IEMs and many don’t have the ability to pull-up this faint sound…….then when you add the GK20 price point here………amazing!
At 00:22 the electric guitar arrives. I’m a guitar player so I always key-in on the timbre and judge it. The thing is all this sonic story telling is a lead-up to the vocals at exactly 00:30. Lucia Cifarelli has done vocals here since 2002 and I find her totally captivating, as maybe I like feisty females? But to fall back to my regularly understood sonic character of the GK20……here we are met with more of the same, as this $99.00 IEM really just goes about it’s day once again portraying the exact same vocal character as it has always done with my weeks of testing. There are no surprises here, and that is a good thing. What this means is not only are we awarded with vocals, but are also introduced with the effects layered about the vocals, yep as at times (especially with a song like this) we become smitten with just how artistic the vocal effects can turn-out. There is a separated off-to-the-right (00:43) as an example of a highlighted vocal delay, and the GK20 shows such subtle fireworks. I mean sure other IEMs go forward and don’t leave this out, except here it is our gift and showcased along with clear and vibrant instrumentation. Is this vocal replay better than the GK100……I think it is? Yet I say this except the GK100 is no slouch, not at all, allowing even more items and details to be found in this song, just the vocals and really everything else for that matter, are not so forward, leaving room for elements to position themselves back to come forward with more resolution into the GK100 stage display.
The cymbal strikes…..that is what GEEK WOLD is about…..to show the world that you too can have such replay. Why? Because it’s a hybrid and because the GEEK WOLD have an ability to promote a sophisticated Piezoelectric top-end. And there is complete naturalness to timbre here…..I mean that’s what is special, as we found out with the Eagle, anyone can throw in a forward and bright cymbal sound, except the art form…..the IEM art form is to make it have correct timbre and make it sit right into the pocket, where you hear it with the best of IEMs.
Excuse my verbose………because I can get side-tracked with this song and write about it endlessly. The point here is that this playback is separated, involved, correct and emotional, in fact this is one single example of total success, success that maybe happens due to GEEK WOLD concentrating on the fundamentals of replay. Meaning it’s all here, all you would want, especially at this particular price point. I mean I randomly chose this song because it is fun to listen to, but also because it is well-recorded and puts-up a set of challenges. Challenges that I know and understand…..because that is what test songs are about. Here my satisfaction results from completeness, size, thoroughness and technicalities as well as tone being just right.

Here is another of my favorites, and not because it is the most thrilling song I have ever heard, but because this song is a tool to understand timbre, and a few other clues which I will get into. Even at the start 00:08 this drum metronome starts up. This is in fact the rhythm the whole song is based around. As this song is part of a gaming soundtrack to which the generated pace here seems to enhance gaming activity. There is a mood which takes place with humans when they partake of a driving game……and we want an element of relaxation, along with the thrills of taking part in a racing adventure. Maybe this metronome is connected to almost our heartbeat, maybe it’s only an added pace that simply lets us know we are in fact getting somewhere as far as progress in the game? Whatever its mission this drum beat can be found played back wrong. In fact there are subtle different intensities to it, yet with-in those intensities the actual tone needs to be represented as a drum, not a slap of a drum. The drum must hold note-weight and be fully formed into a believable representation of a drum…..and gloriously we have that. That may sound like a given, except here we are dealing with an IEM mechanism which (due to tuning) is always in danger of highlighting BA timbre issues. Where here is the use of a single BA given the midrange duties, but wait that is only one driver? With two BA responsible for the high frequencies and two Piezoelectric drivers for the extended highs. Then two DDs for the lows. But this single BA for the midrange has extra importance, at least that is how I hear the GK20? Also for whatever reason this particular BA is called by GEEK WOLD “large-size” lol. I mean it actually sounds like the midrange is what they were focusing on when they designed the GK20, because really the vocals and any other instrumentation are fully represented here. And the character of this middle toned drum is executed super well. The next timbre test comes from the piano in this song……as maybe the song originated as a piano piece and as such these keys are also from the start to the finish. Even at 00:09 we are greeted with the piano introduction, and as such it slowly makes its way front and center. It’s important to realize that while often a repeating sound can be put into the backseat while listening, due to the piano timbre being crucial, it still becomes a center of questions, and yes this is piano super well done. It’s the metallic sheen of the BA which will offer this double edged sword here, being both bright but offering a realness that often we are prejudiced to only accept from Knowles or Sonion. Yet I have to say times are a changing……as don’t you think GEEK WOLD went to a ton of effort to get the correct BA into place? And they really did as far as this piano timbre is concerned. It’s naked and out-front, not hiding in the background here. But to take this song to the next level…….there is introduction of new dynamics right at yep……at 00:43 seconds the creators added a multitude of instruments, a bass beat drum to show they mean business and a wash of midrange synthesizers. Seemingly arriving in a new place into the stage is a thrill as we didn’t expect it. And even though I have heard this song numerous times……the break here is still an honest and rewarding thrill for IEMs to be simply a part of. You see it is all coming together and the sound results are big and emotional. In fact, right at 00:43 seconds the two bass DDs kick-in, the midrange washes take place and even the introduction of way outside stage rhythm additions start their jobs. It’s this satisfying start of the song even before one minute! Yet this can be also a sink or swim moment, as not every IEM has the Hybrid abilities to separate and add warm luster to each and every aspect of this winning display……..except the GK20 does, it does very, very well here and better than the price-point would have you guess.

Here is an addition of more real (recorded) instruments. Meaning the last song was a game soundtrack, yet now we are moving to the big leagues….a full-on blockbuster movie OST. So now more dollars are spent trying to add emotional response to a film experience. And sure enough there is a pay-off………..right from the start. At just 00:11 seconds in the bass cellos are creating a Head-Fi trigger here at Redcarmoose Labs……the rest is history as this tune is creating quite a stir. In fact at the start of this review I said that the low end was maybe better than the GK100? Now to tell you the truth the GK100 has an ounce or two of more bass, it is $200.00 dollars and a lot of instrumental action, sure this OST is slightly bigger and offers maybe slightly more GK100 fireworks. We already learned that the GK100 is going ahead and providing an extra dose of tip-top realism and pizzaz. Yet the GK20 is no slouch and even though the vocal in choir form will show-up in this song later..........right at this point I’m simply getting off on the quality bass action. Its action into the bass response is both deep and yet still careful. I say careful as right at the 00:12 - 00:13 mark, right after the big bass drop there is another accent………………..it is a subtle extra bass additive that just goes to show how complete the GK20 is. Though to be critical here there are violin string accents that will often show-up more vivid with a number of other IEM replays……..and as always I’m listening for them, trying to hear them appear? Sure this audio glitch in the matrix is real, yet as I sit back and chomping banana cookies, I’m simply reporting on it. Sure they are there, just not as heard and not as clear being they're actual string friction bow accents which can often come off more vivid and clear? Yet as my first review of 2024, it doesn’t bother me as much, and especially not as much as reading about it would have you guess. LOL Plus I need to find something missing right? Something that is out of place……And I’m as always trying to figure out why this is……are the strings overshadowed by other more vivid instrumentation? Sure I can hear them, they are just not as separate from the background as regularly heard other times? So I go through and play this beginning over and over…….about nine times so far…..and it doesn’t get any better. In fact it is these violins are the very first things you hear to clue you in on the fact the stereo is on and functioning as correct, making music. I mean there is a dramatic boost of low-end energy which creates the cello and stand-up bass you fully hear……it is just a slight over emphasis which occludes the violins…..not that much of a big deal. Actually things like this are welcomed as there is no such thing as a perfect IEM, and as such issues like this keep it real.

Really cool that I’m ending with this song. And while other IEMs may do those violins better in the last song, they don’t always get this syncopated bass as forward or as vibrant as it is heard here. Right out of the gate at 00:00 you get such a pace maker……..and it is pushed way forward to what could only be described and vibrant and exquisite. Now this song is a toughie and part of my testing regime. I’m actually trying to cause trouble here. The guitar at 00:08 is a defining feature of Symphonic Metal. No where else would they even try to place this buzz-saw of a tone. This is actually a very careful test of BA timbre, and it is an overly busy song with 100 things going off at once. So what we are looking for is first a listenable and true to life guitar tone, then we are exploring just how well the GK20 is able to take the song apart and provide a credible reproduction. There is another reason I chose this guitar tone, because many may be sitting back in their easy chair and laughing with a GEEK WOLD product due to the treble accents ...that it would be better to leave this song for other IEMs to do better with. And there is some truth to that statement, yet there is not a yes, no type of answer here. As with tone there are maybe 10 different levels of perception, meaning most of the time few IEMs get it right anyway. Yet here there is no denying that nothing is left out, nothing is missing, maybe due to the middle “giant” BA, but what makes this whole thing really work out is Charlotte Wessels vibrant vocal imaging. Yep, who cares about those guitars as we now realize there is a method to this madness. That in fact Charlotte Wessels vocals get placed farther out front and make use of contrasts to somehow make it all sound correct and balanced. There are also faint extra accents to the ssssss sound she makes that sounds like an overdub, yet smooth and natural here with GK20 playback. Now I won't gussy up anything, sure I’ve heard this played back less trebly and less bright, which makes me realize that while correct here, it is on the brighter edge of correct. With that said, that doesn’t mean any bass was left out, it is just there is a tilt to the GK20 that maybe will be loved by some with this number, and while maybe showing the song actually for what it is, some would choose a different route.
Music conclusions:
First off, that Chemical Redemption song is an odd-ball and has very little weight in showing what the GK20 is about. Luckily I have switched back to more regular programming to finish this conclusion. Yet I can’t help but notice this slight slant of brighter than regular replay. There are 5 midrange and treble providers doing all this brightness. Yet the two DDs also add the service of grounding everything. The GK20 is balanced but is also offering a window into a more detailed and clear idea of under $100.00 replay. Is some of this treble energy synthetic or over used……..I’m not sure…..but at this price point the GK20 is totally listenable and unique. You have to remember I’m using the most treble centric wide-bore ear-tips to increase the stage size. In fact............a switch over to regular bore can reduce much of this treble energy and bring about a possibly more balanced tone? Still note the picture below……….yep, take note of the maximum treble and maximum soundstage wide-bore silicone ear-tips the GEEK WOLD have included in your package! They want you to experience this ultimate stage playback.

Conclusion:
Depending who you are, the GEEK WOLD may have your name on it. The brand somehow has kept-up with the times to provide an always improving sound per dollar ratio. And while the GK100 came out in May of 2022, and is $200.00, you can tell that GEEK WOLD didn’t let up. In their imagination they thought they may introduce an IEM which was $101.00 dollars less expensive, yet did these airy forward and real sounding vocals……they of course had to also remove 2 drivers and an insanely nice 3 in 1 Hukugei cable to do so. We don’t have that incredible cable like the GK100 has, yet still we have 7 complete drivers for under 100.00. And it sounds like 7 drivers……it really does. Oh, and as far as instrumental music goes, the GK100 does that way better all day long, yet that doesn’t mean the GK20 does it bad, just not as good. Yet those reverberations into how the vocals are presented may make the GK20 the ultimate choice anyway…....that and build and fitment……..I mean common just look at the GK20…......it’s the cat’s meow! You're probably going to expect me to talk about which one would be better for certain genres….....and I’m not. Why? Besides vocals being best with the GK20, both IEMs are super balanced and super efficient at everything, they really are. There is just enough bass with the GK20 to pull-off EDM, just enough shimmer to do violins in Classical, and enough midrange and lower midrange to make that groove happen in Rock. So you see if you add vocals to the GK20 line of features it really does it all…..and that is saying a lot for an IEM priced at $99.00!
And while it’s not everything, phone playback is fine and will suffice during those times when out and about, but I would seriously recommend a dongle or audiophile DAP to feed the GK20 the style of food it’s accustomed to. When roaming out in the city the GK20 seems to be made for this style of elements, offering a deep custom fit and really good noise occlusion, being it is fully solid. Yet on the medium smaller side, and being only 5 grams per IEM, there are reasons for this style of fitment. And to think they squeezed in all 7 drivers? Yep, each driver does something to bring the sound frequencies to life. Separation, tone sculpturing, vocal and instrument realism....all into a sumptuous stage display…….....…need I say more?

Yet I really am curious to hear them, as somehow GEEK WOLD has started to make their lesser priced IEMs sound pretty good? While I have only heard 2 GEEK WOLD examples, both the GK100 and GK20 sound both a little the same and a little different. So to let you understand the history of GEEK WOLD…..

There was also a GEEK WOLD GK3 that was released in 2018, yet pretty much overlooked by the Head-Fi community. Yet the original GK10 was a success and really is the single earphone which brought GEEK WOLD to Head-Fi. For the most part (at the time) the GK10 provided a sound that for the money was untouchable……I hear.
The original GK10:
1) 8mm titanium dome dynamic bass
2) 7mm graphene dynamic for midrange
3) A BA for treble
4) And two piezoelectric for treble extension…..just to top things off.
Such an invention would compete with many IEMs in 2021 even up to $200 so I'm told?
GK10s:
I mean sure the GK10 is legendary, and most likely the GK10s will be a subtle improvement, I can guess?
The GEEK WOLD GK20:
But to take this GK20 seriously, I probably like the bass better than the double the money GK100? And even though I have only heard two GEEK WOLD products, I do understand where they are coming from…….GEEK WOLD is attempting to give the budget world a taste of high-end treble. Really that is my generalization of what their goals are……..as such I can only guess their start here at Head-Fi (with the GK10) was based on that same premise? GEEK WOLD is putting a lot of parts under the hood.
GEEK WOLD GK80 4 drivers $46.90
GEEK WOLD GK10s 5 drivers $49.90
GEEK WOLD GK20 7 drivers $99.00
GEEK WOLD GK100 9 drivers $200.00
GEEK WOLD GK200 10 drivers $350.00
Now to level with you, I really think the GK100 is on the larger side of big. I have seen pictures and laughably the (huge) GK200 dwarfs it……..so? Sure you want the GK200 10 drivers and are willing to put-up with that specific size, fine then, also that size difference looks to be mostly the added thickness over what the GK100 example is, as seen side-by-side in photos. Yet as little as I know about GEEK WOLD’s line up, this GK20 is a whole new deal, a whole new way of making an IEM. Notice when you see both the GK100 and GK20 (side-by-side) in my photographs, you can start to realize that GEEK WOLD took a whole new approach to making the GK20. Yep, it is solid 3D printed resin, where the GK100 is a hollow shell. And while the GK20 is 5 grams and the GK100 6 grams, the GK20 is see-through and the GK100 a totally opaque hollow shell. But more than that, the GK20 has way more curves to help it sit inside your ear farther. And finally the GK20 is truly a medium-small size………and for some that is going to be a big deal. So custom universal 3D designed and smaller (for me) better fitting than the GK100 form-factor.
How do the GK100 and GK20 compare sound wise?
First off the GK100 takes slightly more juice to get it going. And bass is actually more substantial with how the GK100 portrays a song. With that said (and if you read my GK100 review) the mids are a tad dry, or not as fully worked-out to portray vocal life in general, even compared to the GK20. What I’m trying to say is the vocals are forward and holding placement, it is just that the actual tone is on the dry side. Now I hope you understand this is not as big of a deal as it seems. Why? Well this giant groovy bass action and size of stage, makes the GK100 incredibly fun anyways. The fact that it is the ultimate Hybrid being built with no less than 9 drivers, using Piezoelectric, BA and DD to function. Where the GK20 goes ahead and adds a pure flavor of moving more upfront imaging and the vocals follow along to become showcased ever so slightly better. Just ever so slightly cleaner and more natural.
Heck, I can see the owner of GEEK WOLD sitting in the boardroom and having a discussion with the sound engineers. He is saying make me a new IEM and make it smaller, make it have more upfront and personal vocals……you don’t have to make these changes too different in the vocal department except maybe 20% or 28% of naturalness will make a world of difference to our consumers. This change is adding slight note-weight to the GK20 vocals and somehow that adds reverberation comprehension? Heck……what am I talking about? The vocals are simply clearer……that’s all. Now keep in mind that if you already owned the GK100 and primarily listened to instrumentals…..stay with your GK100. The GK100 increased separation and itemization is a real thing, over the slightly more together (forward) stage and item placement found in the GK20.
The truth is the GEEK WOLD GK100 has a smoother and more sophisticated instrument generation, especially up-top. Stuff is found into better detail and of more resolution, more lifelike even, falling into a better arranged and more realistic placement. So yes, you can tell it is the more expensive IEM, only the GK20 has better vocals……..more lifelike vocals!
The trebles GK100 v GK20:
I’m not one to concentrate on treble, I’m more into midrange and bass, yet I know trebles are super important to many, and maybe more so if a person is curious about a possible GEEK WOLD product? I’m partially guessing that this brand is trying to bring an expensive and sophisticated treble response to the value market, I mean there is room for such focus out there. And sure enough that is what is going on, all this complete itemization and structuring of separated treble components. The shakers, the hi-hats, the cymbals…..and those sounds that are indistinguishable as to what they truly are, but reside way up there in the treble response regions. To level with you, the GK100 does those better, and not just the sounding clearer, but even the reverberations of the treble items…….the GK100 room response is found to be more complete, clearer and better separated. Yet, if you truly wanted better vocals played, all of that maneuvering may matter less.
Conclusion of GK100 v GK20:
All this talk of one being better at this or that could lead someone into thinking that one IEM is faulty or off. When the truth of the matter is both IEMs lend themselves to very balanced and thoroughly entertaining replay……..as if you were strictly into instrumentals and listen to vocal music secondary…then the GK100 would be the way to go. If you wanted airy and forward vocals which contain an element of a breathy human character…..then the GK20 would be your choice.
The GK20 v the MEAOES Eagle:
I reviewed the MEAOES Eagle almost exactly a year ago on January 5th, 2022. Coming in at $149.90 the MEAOES Eagle fits right in with our side-by-sides. I mean just look at how the shell seems to be made at the same factory as GEEK WOLD………..but more than that the Eagle is also going ahead to offer more treble details and definition same as our IEMs above. Those who have been around maybe remember HIFIBOY, well this is that brand. We are gifted here with 2BAs and 2DDs. One DD is 7.5mm and the other is 8mm.
Here I would call the Eagles personality as the hard-trier. Where there is this ultimate treble definition, yet it isn’t of the best way blended nor of correct timbre. There is this synthetic aura to the top-end yet to someone trying out $150.00 IEMs in a shop this brightness and in a way technicality could come off exciting……….at first. And even a year later I have always been pulling the MEAOES Eagle out to see how different cables may help align the sonic response into a more cohesive and toned down approach. And sure enough a few weeks ago I really hit pay dirt. Which is one of the values of cable rolling, that every once in a while you have this magic cable that can truly change things for the better. Now the other extreme here is the bass! Yep, the bass is actually quite good for what it is. But to truly put things into perspective…….the Eagle makes the GK20 look surprisingly good…….almost perfect in comparison, it’s just a fact of life that the treble with the GK20 is just way better done. Also surprisingly the vocals with the Eagle regardless of the treble were actually quite clear and forward, really very good. Still the fitment and feel of the GK20 is better as well as the outside noise occlusion which gets an increase due to fit. Though to summarize this battle, it’s the midrange and top-end timbre that the GK20 ends up doing so much better…..that and better vocals……for less money, too! It’s just that the GK20 comes off as the more cohesive and mature player…….smaller and better fitting too, sorry to say.
Build:
2 Piezoelectric ultra treble high frequency drivers
2 Treble BA drivers
1 Midrange “BIG” BA
2 Dynamic Drivers
A 3 channel, 4 frequency internal design. There is a titanium DD for the super lows, and a LCP DD on top responsible for the lows. Such 3BA-2DD-2PZT arrives at a 7 driver IEM inside a compact 3D printed shell.
Cable:
Right before I started the below music tests I went and prequalified the included cable. What that means is (the included cable) could be less than optimal to do complete listening tests if it had sound quality issues. And I was suspicious as I had spent an entire evening using the included cable on a (different) IEM. And when I switched cables to a different aftermarket cable I found the stage opened up a little. Now you may wonder as to the reason why I chose the GEEK WOLD included cable for this other new IEM? Reason being is it is 4.4mm……and a great way to access the 4.4mm amplifier in some (now maybe most) DAPs. So in the end I actually prequalified the included once more and while not the very best cable I kind know why they included it with this package. 1st off the cable has a look and feel that is spectacular. The included cable looks like money with the gorgeous trademark named 4.4mm plug. The way the ergonomics work out in daily use. The way the chin cinch works, and finally the color coded 2Pin plugs and ear-hooks. Also who knows why it wasn’t the very best with a random IEM but I came to a definitive understanding as to how the cable performs. It must have a touch of silver over the use of copper because what this cable does is accentuates the forward positioning of imaging. Meaning trying other warmer cables the effect was less contrast and while slightly smoother, did not bring out the wanted vibrancy and even vocals inherent in the character of the GK20. So in my mind I went back to the boardroom ideas of GEEK WOLD and I could hear the GEEK WOLD President saying……I want vocals with this one. Being the last GK100 had meh vocals, do me and the listening community a favor and add vocals, we don’t want the reputation of so-so vocals, especially since this is China the epicenter of vocal music. And sure enough they added a cable which helped push the vibrancy………so much that after understanding what GEEK WOLD is up to with the personality of this cable, and the fact that it came with the IEM, and the fact that it’s beautiful……..well you get the message. Besides the GK20 is so well rounded that it goes with phones and DAPs and desktops. Yet I bet GEEK WOLD included a 4.4mm plug standard as they found out the GK20 craves a good source to become its best? I mean sure you can get the GK20 a regular 3.5mm plug and hook it to your phone and the sound is full and not thin………….except there is a profound difference in regards to stage and imaging, and even a more authoritative nature arriving at your favorite DAP or desktop. So to summarize this rambling……..the cable is fine and actually has many redeeming factors in daily use, you don’t need to change, except there are other places in tone that can be found by using some GUCCI cable you have laying around…..the GK20 has the ability to go there.

This song is one of my all time favorites and it contains vocals so going with the program here. But more than that, I’m more into instrumental music except I do appreciate good vocals from time to time and understand the concept of how they are done by an IEM character. Here are female vocals, yet I tested many other examples of male vocals to learn about the vocal abilities presented here. Probably the message to this song is that the GK20 doesn’t just to vocals…..but performs in such a balance that it does it all………I mean right off….right off the bat this is what I’m hearing! At 00:16 there are forward and punchy bass actions……..where it may be a layering of both synth bass and regular bass? Or maybe it’s all synth bass…..whatever it is there is a quality to where if it cuts through, and I’m content with this demeanor. If we rewind there is a wolf-howl at the start……at only 00:12 we hear the reverberations contained in this sound effect, bringing the realization that this isn’t your parents $99.00 IEM. And while going to the very start of the song there are thunder-clap sounds…………but to generate an idea of truly the resolution here there is a faint sound at 00:12……..it may be some movement in the studio, maybe it’s supposed to represent a lightning strike here? Whatever it is…..this is what an expanded top-end is about……the small stuff…in great detail and heard. I can look over at my collection of IEMs and many don’t have the ability to pull-up this faint sound…….then when you add the GK20 price point here………amazing!
At 00:22 the electric guitar arrives. I’m a guitar player so I always key-in on the timbre and judge it. The thing is all this sonic story telling is a lead-up to the vocals at exactly 00:30. Lucia Cifarelli has done vocals here since 2002 and I find her totally captivating, as maybe I like feisty females? But to fall back to my regularly understood sonic character of the GK20……here we are met with more of the same, as this $99.00 IEM really just goes about it’s day once again portraying the exact same vocal character as it has always done with my weeks of testing. There are no surprises here, and that is a good thing. What this means is not only are we awarded with vocals, but are also introduced with the effects layered about the vocals, yep as at times (especially with a song like this) we become smitten with just how artistic the vocal effects can turn-out. There is a separated off-to-the-right (00:43) as an example of a highlighted vocal delay, and the GK20 shows such subtle fireworks. I mean sure other IEMs go forward and don’t leave this out, except here it is our gift and showcased along with clear and vibrant instrumentation. Is this vocal replay better than the GK100……I think it is? Yet I say this except the GK100 is no slouch, not at all, allowing even more items and details to be found in this song, just the vocals and really everything else for that matter, are not so forward, leaving room for elements to position themselves back to come forward with more resolution into the GK100 stage display.
The cymbal strikes…..that is what GEEK WOLD is about…..to show the world that you too can have such replay. Why? Because it’s a hybrid and because the GEEK WOLD have an ability to promote a sophisticated Piezoelectric top-end. And there is complete naturalness to timbre here…..I mean that’s what is special, as we found out with the Eagle, anyone can throw in a forward and bright cymbal sound, except the art form…..the IEM art form is to make it have correct timbre and make it sit right into the pocket, where you hear it with the best of IEMs.
Excuse my verbose………because I can get side-tracked with this song and write about it endlessly. The point here is that this playback is separated, involved, correct and emotional, in fact this is one single example of total success, success that maybe happens due to GEEK WOLD concentrating on the fundamentals of replay. Meaning it’s all here, all you would want, especially at this particular price point. I mean I randomly chose this song because it is fun to listen to, but also because it is well-recorded and puts-up a set of challenges. Challenges that I know and understand…..because that is what test songs are about. Here my satisfaction results from completeness, size, thoroughness and technicalities as well as tone being just right.

Here is another of my favorites, and not because it is the most thrilling song I have ever heard, but because this song is a tool to understand timbre, and a few other clues which I will get into. Even at the start 00:08 this drum metronome starts up. This is in fact the rhythm the whole song is based around. As this song is part of a gaming soundtrack to which the generated pace here seems to enhance gaming activity. There is a mood which takes place with humans when they partake of a driving game……and we want an element of relaxation, along with the thrills of taking part in a racing adventure. Maybe this metronome is connected to almost our heartbeat, maybe it’s only an added pace that simply lets us know we are in fact getting somewhere as far as progress in the game? Whatever its mission this drum beat can be found played back wrong. In fact there are subtle different intensities to it, yet with-in those intensities the actual tone needs to be represented as a drum, not a slap of a drum. The drum must hold note-weight and be fully formed into a believable representation of a drum…..and gloriously we have that. That may sound like a given, except here we are dealing with an IEM mechanism which (due to tuning) is always in danger of highlighting BA timbre issues. Where here is the use of a single BA given the midrange duties, but wait that is only one driver? With two BA responsible for the high frequencies and two Piezoelectric drivers for the extended highs. Then two DDs for the lows. But this single BA for the midrange has extra importance, at least that is how I hear the GK20? Also for whatever reason this particular BA is called by GEEK WOLD “large-size” lol. I mean it actually sounds like the midrange is what they were focusing on when they designed the GK20, because really the vocals and any other instrumentation are fully represented here. And the character of this middle toned drum is executed super well. The next timbre test comes from the piano in this song……as maybe the song originated as a piano piece and as such these keys are also from the start to the finish. Even at 00:09 we are greeted with the piano introduction, and as such it slowly makes its way front and center. It’s important to realize that while often a repeating sound can be put into the backseat while listening, due to the piano timbre being crucial, it still becomes a center of questions, and yes this is piano super well done. It’s the metallic sheen of the BA which will offer this double edged sword here, being both bright but offering a realness that often we are prejudiced to only accept from Knowles or Sonion. Yet I have to say times are a changing……as don’t you think GEEK WOLD went to a ton of effort to get the correct BA into place? And they really did as far as this piano timbre is concerned. It’s naked and out-front, not hiding in the background here. But to take this song to the next level…….there is introduction of new dynamics right at yep……at 00:43 seconds the creators added a multitude of instruments, a bass beat drum to show they mean business and a wash of midrange synthesizers. Seemingly arriving in a new place into the stage is a thrill as we didn’t expect it. And even though I have heard this song numerous times……the break here is still an honest and rewarding thrill for IEMs to be simply a part of. You see it is all coming together and the sound results are big and emotional. In fact, right at 00:43 seconds the two bass DDs kick-in, the midrange washes take place and even the introduction of way outside stage rhythm additions start their jobs. It’s this satisfying start of the song even before one minute! Yet this can be also a sink or swim moment, as not every IEM has the Hybrid abilities to separate and add warm luster to each and every aspect of this winning display……..except the GK20 does, it does very, very well here and better than the price-point would have you guess.

Here is an addition of more real (recorded) instruments. Meaning the last song was a game soundtrack, yet now we are moving to the big leagues….a full-on blockbuster movie OST. So now more dollars are spent trying to add emotional response to a film experience. And sure enough there is a pay-off………..right from the start. At just 00:11 seconds in the bass cellos are creating a Head-Fi trigger here at Redcarmoose Labs……the rest is history as this tune is creating quite a stir. In fact at the start of this review I said that the low end was maybe better than the GK100? Now to tell you the truth the GK100 has an ounce or two of more bass, it is $200.00 dollars and a lot of instrumental action, sure this OST is slightly bigger and offers maybe slightly more GK100 fireworks. We already learned that the GK100 is going ahead and providing an extra dose of tip-top realism and pizzaz. Yet the GK20 is no slouch and even though the vocal in choir form will show-up in this song later..........right at this point I’m simply getting off on the quality bass action. Its action into the bass response is both deep and yet still careful. I say careful as right at the 00:12 - 00:13 mark, right after the big bass drop there is another accent………………..it is a subtle extra bass additive that just goes to show how complete the GK20 is. Though to be critical here there are violin string accents that will often show-up more vivid with a number of other IEM replays……..and as always I’m listening for them, trying to hear them appear? Sure this audio glitch in the matrix is real, yet as I sit back and chomping banana cookies, I’m simply reporting on it. Sure they are there, just not as heard and not as clear being they're actual string friction bow accents which can often come off more vivid and clear? Yet as my first review of 2024, it doesn’t bother me as much, and especially not as much as reading about it would have you guess. LOL Plus I need to find something missing right? Something that is out of place……And I’m as always trying to figure out why this is……are the strings overshadowed by other more vivid instrumentation? Sure I can hear them, they are just not as separate from the background as regularly heard other times? So I go through and play this beginning over and over…….about nine times so far…..and it doesn’t get any better. In fact it is these violins are the very first things you hear to clue you in on the fact the stereo is on and functioning as correct, making music. I mean there is a dramatic boost of low-end energy which creates the cello and stand-up bass you fully hear……it is just a slight over emphasis which occludes the violins…..not that much of a big deal. Actually things like this are welcomed as there is no such thing as a perfect IEM, and as such issues like this keep it real.

Really cool that I’m ending with this song. And while other IEMs may do those violins better in the last song, they don’t always get this syncopated bass as forward or as vibrant as it is heard here. Right out of the gate at 00:00 you get such a pace maker……..and it is pushed way forward to what could only be described and vibrant and exquisite. Now this song is a toughie and part of my testing regime. I’m actually trying to cause trouble here. The guitar at 00:08 is a defining feature of Symphonic Metal. No where else would they even try to place this buzz-saw of a tone. This is actually a very careful test of BA timbre, and it is an overly busy song with 100 things going off at once. So what we are looking for is first a listenable and true to life guitar tone, then we are exploring just how well the GK20 is able to take the song apart and provide a credible reproduction. There is another reason I chose this guitar tone, because many may be sitting back in their easy chair and laughing with a GEEK WOLD product due to the treble accents ...that it would be better to leave this song for other IEMs to do better with. And there is some truth to that statement, yet there is not a yes, no type of answer here. As with tone there are maybe 10 different levels of perception, meaning most of the time few IEMs get it right anyway. Yet here there is no denying that nothing is left out, nothing is missing, maybe due to the middle “giant” BA, but what makes this whole thing really work out is Charlotte Wessels vibrant vocal imaging. Yep, who cares about those guitars as we now realize there is a method to this madness. That in fact Charlotte Wessels vocals get placed farther out front and make use of contrasts to somehow make it all sound correct and balanced. There are also faint extra accents to the ssssss sound she makes that sounds like an overdub, yet smooth and natural here with GK20 playback. Now I won't gussy up anything, sure I’ve heard this played back less trebly and less bright, which makes me realize that while correct here, it is on the brighter edge of correct. With that said, that doesn’t mean any bass was left out, it is just there is a tilt to the GK20 that maybe will be loved by some with this number, and while maybe showing the song actually for what it is, some would choose a different route.
Music conclusions:
First off, that Chemical Redemption song is an odd-ball and has very little weight in showing what the GK20 is about. Luckily I have switched back to more regular programming to finish this conclusion. Yet I can’t help but notice this slight slant of brighter than regular replay. There are 5 midrange and treble providers doing all this brightness. Yet the two DDs also add the service of grounding everything. The GK20 is balanced but is also offering a window into a more detailed and clear idea of under $100.00 replay. Is some of this treble energy synthetic or over used……..I’m not sure…..but at this price point the GK20 is totally listenable and unique. You have to remember I’m using the most treble centric wide-bore ear-tips to increase the stage size. In fact............a switch over to regular bore can reduce much of this treble energy and bring about a possibly more balanced tone? Still note the picture below……….yep, take note of the maximum treble and maximum soundstage wide-bore silicone ear-tips the GEEK WOLD have included in your package! They want you to experience this ultimate stage playback.

Conclusion:
Depending who you are, the GEEK WOLD may have your name on it. The brand somehow has kept-up with the times to provide an always improving sound per dollar ratio. And while the GK100 came out in May of 2022, and is $200.00, you can tell that GEEK WOLD didn’t let up. In their imagination they thought they may introduce an IEM which was $101.00 dollars less expensive, yet did these airy forward and real sounding vocals……they of course had to also remove 2 drivers and an insanely nice 3 in 1 Hukugei cable to do so. We don’t have that incredible cable like the GK100 has, yet still we have 7 complete drivers for under 100.00. And it sounds like 7 drivers……it really does. Oh, and as far as instrumental music goes, the GK100 does that way better all day long, yet that doesn’t mean the GK20 does it bad, just not as good. Yet those reverberations into how the vocals are presented may make the GK20 the ultimate choice anyway…....that and build and fitment……..I mean common just look at the GK20…......it’s the cat’s meow! You're probably going to expect me to talk about which one would be better for certain genres….....and I’m not. Why? Besides vocals being best with the GK20, both IEMs are super balanced and super efficient at everything, they really are. There is just enough bass with the GK20 to pull-off EDM, just enough shimmer to do violins in Classical, and enough midrange and lower midrange to make that groove happen in Rock. So you see if you add vocals to the GK20 line of features it really does it all…..and that is saying a lot for an IEM priced at $99.00!
And while it’s not everything, phone playback is fine and will suffice during those times when out and about, but I would seriously recommend a dongle or audiophile DAP to feed the GK20 the style of food it’s accustomed to. When roaming out in the city the GK20 seems to be made for this style of elements, offering a deep custom fit and really good noise occlusion, being it is fully solid. Yet on the medium smaller side, and being only 5 grams per IEM, there are reasons for this style of fitment. And to think they squeezed in all 7 drivers? Yep, each driver does something to bring the sound frequencies to life. Separation, tone sculpturing, vocal and instrument realism....all into a sumptuous stage display…….....…need I say more?
