MANDATORY INTRODUCTION

Dear reader, please keep in mind that whenever there is an opinion in a review, it is my opinion, which may differ significantly from yours. We are all different from each other and have different tastes, and something that does not give me an accelerated heartbeat, you can have great fun, so I always recommend listening before buying if there is such an opportunity. I would also like to point out that in the evaluation of individual parameters, as well as the entire headphones, I try to relate to the price level that has been set for them, which simply means that any opinion I give should be followed by the thought “.... for its price”. I believe this is the only fair form of evaluation and best represents the value of the reviewed item.

INTRODUCTION


Today I would like to introduce you to the in-ear monitors from Kiwi Ears, model: FORTEZA. The headphones were given to me for the purpose of describing my true impressions. At no time was the direction of my review given to me and it is a 100% reflection of my feelings

PRESENTATION


1710264442730-01.jpeg


The packaging of the headphones is quite sizable and looks pretty cool. The headphones can be purchased in three different color versions. The color of the model that was sent to me is “BLUE”, but the dominant color of the packaging is sea green which happens to go very nicely with the color of the package, as it is actually a mix of green and blue. In the package we find, of course, a pair of headphones, some paperwork, a cable, and several sets of tips. The cable is quite thin and rather not sensational, but also not the worst cable I've dealt with - it's kind of average, which, considering the selling price, is rather a bit disappointing, but not a tragedy – at least it doesn’t get tangled. The set also comes with a small, rigid fabric case bearing the manufacturer's logo. As for the appearance of the headphones themselves, it makes a very good impression. The shell of transparent, tinted resin, through which you can see the construction of the headphones themselves (2 DD+1BA), with a two-color front cover that shimmers like glitter and brings the look of it closer to jewelry than headphones, but in a good way.

TUNING AND SOUND:

Well, balance it is not :)

To my mind, it's a warm V tuning, especially with boosted bass, but also exposed treble. I was immediately struck by the observation that their shape allows for quite effective passive isolation, placing the listener in a kind of bubble, and cutting him off from external sounds.

A few words about the sound itself: it is dynamic, lively, and energetic. The bass is dominant and at times even overwhelming. Treble tones can draw excessive attention to themselves, by overemphasizing sibilants, for example. The midrange seems a bit withdrawn, maybe not a lot, but enough so that I, unfortunately, more than once encountered a situation where, in the calmer moment of a song, I would turn up the volume to a level that provided clear and pleasing vocals, only to turn it down a moment later, because suddenly the amount of bass, or the harshness of the treble simply began to bother me.

1714690394185-01.jpeg


Well, let's go through the individual regions

Bass:

The bass is nice at times, so bouncy and fat, but unfortunately for the most part it's just too much and can tire you out. It also happens to rumble …. in a bad way. As a plus, I can report that it has texture and a significant portion of sub-bass, but I don't think it's sophisticated enough to consider FORTZA as a basshead set. I believe that a true basshead is not only a lover of the quantity, but also of the quality of the bass emitted, and with that, it is average.

Mids:

The vocals are not the strongest aspect of this set, because, on the one hand, the male vocals are at times drowned out by excessive bass and can grumble (Iggy Pop - Candy), and the female vocals sound quite unnatural, due to the boosted treble. Well, and it is this presentation of the vocals, characterized by a kind of harshness in the sound, that I consider one of the worst aspects of this set.

Treble:

When it comes to vocals, one has to reckon with local sibilants seeping in at the ends of words, especially when dealing with female singing. As for the sound of percussion cymbals, it resembles more the sound of a meshed snare drum tension than a vibrating cymbal. It often sounds like such a hiss, which occurs frequently and can be annoying - it's not the spark that trebleheads love. Although there is a lot of treble, it's not very disturbing, well, unless we choose songs exposing these registers, or if you’re sensitive to them, then we have a festival of crackle, sibilants, and general brightness from which one's eyes squint, but in 80% of songs, it was tolerable. This increased decibels in the high registers does give the illusion of purity of sound. The sense of clarity is being built by the fact that since we are hearing a lot of detail, the sound must be clean, but in fact it’s based on artificial sounds, and unfortunately, this action distorts the sound of instruments and vocals, making them quite significantly different from the natural sound.

1714690033947-01.jpeg


PAIRING

Due to the rather sharp treble, it is recommended to use tips that will tame them a bit for us. Analyzing the EartipGuide database from the AudioReviews.org website, I was able to pull out a few tip models that will help us with this:

- Ostry OS3000 - the only example that significantly reduces treble, but also enhances bass, so if you want less bass, it's worth choosing something else

- Moondrop Spring Tips - as described, they take off some bass and sub-bass, bringing the midrange closer while being fairly neutral for treble

- SpinFit CP145 - by boosting the midrange, and leaving the bass and treble at the initial level, you can bring the sound slightly closer to balance

I just got on with the SpinFit CP145s quite tolerably, but I think the use of foams can also help.

As for pairing with the source, it's not easy, because, for example, pairing with KiwiEars Allegro (ES9028Q2M), is sometimes characterized by a rather dull and sluggish sound presentation, while with Moondrop Dawn Pro (CS43131) is overly energetic. Pairing went well with the SONY A55 DAP (Mr. Walkaman mod), with which the Forteza created the most natural timbre, but also the most spacious sound. Pairing with the MuseHiFi M1, or the TC35c from DDHiFi (ALC5686) admittedly provided improved holography, but also exposed this set's weaknesses in treble presentation.

Technicalities:

Despite the dark tuning, the presentation of sounds itself on the potential for holography, with a rather rich background, unfortunately often drowned out by over-exposure of low frequencies, or an annoying sound of, for example, a drum cymbal. As for imaging, there is nothing sensational enough going on in this area to mention. The separation of instruments is pretty cool and, for example, in the song Pearl Jam - Even Flow the guitars on overdrive were very clearly separated from each other and from the rest of the instruments. Well, all in all, one other thing that comes to mind is the very pleasant details associated with the dicing sounds on the rhythm guitar strings that the headphones were able to pull out of the tracks, probably by enhancing the treble, but nevertheless, they quite pleasantly enriched the perception of the tracks.

SOUND SUMMARY:

If you're looking for a balanced sound, the Forteza is not for you.

What we have here is V-type tuning, and that with the “corners” of the letter V exposed.

Of course, with this tuning, the Forteza will be suitable mainly for popular music, electronic probably, but also for rock. I think they can also be safely used for watching movies because with their low and substantial bass, they can shake the viewer at the moment of more spectacular scenes, which, by the way, made me think of the sound presentation used by some multiplex cinemas: “lots of basses, let it shake the viewer”. It may even be suitable for jazz, but you have to reckon that, for example, double bass at times may sound too .... majestic :) and thus unnatural. Similarly the sound of the piano, which when covered with so much bass loses its naturalness of sound, especially the keys in the lower registers. About the fact that female vocals sound quite unnatural, I wrote a little earlier.

And what they will work well for: They will work well in dynamic, soaring music, but ..... as long as the amount of bass doesn't tire you out or give you a headache (which, by the way, happened to me a few times), and if the boosted treble doesn't constantly focus your attention on crackling, clanging drum cymbals or sibilant hisses. .

The best solution: EQ

If your music player or phone is Android-based, WAVELET will come to your rescue. A great app for changing the tuning of your headphones by applying various types of corrections, such as those generated on the squiglink website. For those who don't know what it's about, here it is in a nutshell: the squiglink site has several databases of headphone measurements, including FORTEZA and many, many others. After loading a few charts, you can use the EQUALIZER tab and the AUTOEQ function to generate a set of corrections to the base tuning to bring it closer to the target tuning. These corrections can then be exported to a txt file, which can then be imported in WAVELET. WAVELET is not a player, it's an application that captures the audio stream coming out of your device and applies the indicated corrections to it. That's it in a nutshell, as the subject of eq itself is a bit more complex. You can also apply corrections yourself, by adjusting the number of decibels at each frequency. For my part, I can suggest removing the sub-bass (20-60Hz by about 3db and 80-120Hz by about 1.5db), and making the low end from 2kHz - 16kHz also by about 3 db. This should calm the bass a bit and exposing the male vocals but also should make the female vocals more realistic. These are just my suggestions, but I think that if you dedicate some time and commitment, you will be able to adjust the FORTEZA curve to your liking.

1714690201393-01.jpeg


SUMMARY

I think the initial expected price ($59) for these headphones is a bit overpriced compared to what the competition on the market offers. For those looking for a more balanced and natural sound, I recommend looking at the EPZ Q5, QoA Gimlet, or Simgot EW200 - they offer a more balanced and natural sound. Nonetheless, the Kiwi Ears Forteza, while not to my liking, is not unlistenable and also has some pluses, and with the proper application of EQ will easily achieve a rating of 4-4.5 / 5.

Kiwi Ears Forteza is a headphone that doesn't try to sound natural, just entertaining. The implemented tuning, however, even for an entertaining one, carries a number of color changes that may add dynamics, but at the same time they are very far from natural sound and in my opinion, will be suitable only for people for whom this is not an important issue.

Kiwi Ears Forteza Review

The Kiwi Ears Forteza is a hybrid, 1BA and 2DD, in-ear monitor that retails for $59. Yes, you have read it right, one balanced armature and two dynamic drivers and not the opposite. The Forteza uses one high-mid balanced armature, one 10mm mid-range dynamic and 10mm bass dynamic drivers. This unique combination fulfills a full sound from 20Hz to 20kHz. The drivers are carefully implemented with the aid of a three-way passive crossover system that is tuned for a rich and lush sound signature. All three drivers are in-house developed by Kiwi Ears.

Non Audio stuff

The ear-shells are 3D printed using a skin friendly resin compound and have a semi-custom anatomical shape. They are lightweight and compact thus very comfortable to wear. This is a clean and beautiful looking earphone that isolates well and is suitable for all day use without causing any discomfort. The Kiwi Ears Forteza is available in blue, black and purple.

The Forteza uses a 2-pin detachable cable with high quality aluminum plugs. It is a soft and lightweight cable without much friction noise but it is also rather thin, it gets easily tangled and looks fragile. The package also includes three types of silicone ear-tips in three sizes each and a very nice carrying case with a side zipper.

IMG_20240215_133012-wm-46613.69999998808_watermarked.jpg


Audio stuff

The Kiwi Ears Forteza (32Ω - 103 dB/mW) is moderately easy to drive, it doesn't need special amplification but a powerful USB DAC dongle is strongly recommended if you want to move these two dynamic drivers. As an example, the FiiO KA1 is sufficient enough but the iBasso DC03PRO and the Shanling UA1 Plus are better and more effective.

The Kiwi Ears Forteza has a deeply “V” shaped tuning which emphasizes bass and treble, pushing mid-range at the background. The low-end is very extended with plenty of punchy sub-bass and emphasized bass. A fun and warm tuning that is very enjoyable with all kinds of modern electronic music as the Forteza has the means to reproduce the deepest bass notes with a hefty and visceral texture. The bass is dynamic, explosive and impactful but not that tight and well controlled, decay time is longer than the ideal, there is an audible cup reverb and it gets a bit challenging for the driver to keep up with timing and definition at busy passages. The bass is emphasized and prominent but it is not annoyingly dominating while bleeding into the mid-range is not that much as to severely affect clarity and transparency.

Despite the upper mid-range getting the lion's share, the overall tonal balance is rather acceptable and the Forteza doesn't sound too shouty or shrill as long as you don't listen too loud. Clarity and separation are good for the category, resolution is above average but while the timbre is not that artificial it sometimes lacks in tonal accuracy and realism. The use of a dynamic rather than a BA driver for the mids helps with textural coherency, the sound is full and weighty just like in the lower frequencies while the Forteza has an open sounding presentation that is not claustrophobic.

This doesn't happen in the treble though which is less weighty and thinner sounding than the mid and lower frequencies thus compromising overall texture integrity. The treble is emphasized in order to counterbalance with the accentuated bass, adding energy, airiness and sparkle to the sound. The Forteza is a bit bright sounding but not that harsh or piercing. The real issue that makes the treble the weakest link of the Kiwi Ears Forteza is its textural and timbral qualities. The quality of the treble is below average, the sound is too artificial and metallic with a paper-thin texture and bad tonal accuracy, as a result most higher pitched instruments sound fake and out of tune. You can still get plenty of enjoyment with several types of music, like electronic but the Forteza doesn't fare well with acoustic music.

Conclusion

The Kiwi Ears Forteza is a very comfortable and lightweight IEM with a polarizing tuning that can be fun and engaging with some kinds of music and rather uninspiring with others. If you don't care much about tonal accuracy and you like plenty of sub-bass that is combined with mid-range clarity and a sparkling treble then the Kiwi Ears Forteza might be the right choice for you.

“Cause, baby, there ain't no mountain high enough, Ain't no valley low enough, Ain't no river wide enough”


~~line from Ain't No Mountain High Enough, a song by Marvin Gaye and Tammi Terrell.


Kiwi Ears as an audio company was established recently and they have a good relationship and strong connection with LINSOUL, a popular online store that serves as a distributor for Chinese portable audio products for international markets. I actually did a substantial review of products for them and I also published a substantial number of review articles on Kiwi Ears products that I'm quite transparent about.

20240215_164424.jpg


What I have here is their latest IEM with hybrid driver configuration for entry-level offering, The Kiwi Ears Forteza. The Kiwi Ears Forteza as an IEM with hybrid driver set-up, it has two (2) dynamic drivers and one (1) balanced armature driver which is quite an uncommon configuration.

20240215_164631.jpg


The dynamic drivers that were implemented on this set are 10mm and 6mm which are used for lows and midrange frequency respectively. The lone custom-built balanced driver is a tweeter-type one used to support on the midrange up to ultra-high frequencies for more crisp, brighter tone and better clarity. It is said that these drivers are connected with 3-way passive crossover to achieve that lush, dynamic and musical sound quality that makes it more appealing and engaging.

20240215_165252.jpg
20240215_165638.jpg


The drivers were encased in a medical-grade resin shell which are known to have some hypoallergenic properties. Like all Kiwi Ears IEMs, The Forteza also has an UIEM-style shell chassis that surely offers superior fitting and comfort to all ear sizes. It has a blue-ish green colour scheme with Kiwi Ears logo at faceplate. The 0.78mm 2-pin connector was still used on this set as it is the most stable and known to have a consistent interchangeable mechanism among all types of connector.

20240215_164702.jpg


With the UIEM-style shell chassis that the Forteza has, it really snugs well to my ears and I don't encounter any issues in terms of comfortability. The passive noise isolation of this one is excellent as I could barely hear a considerable amount of external noises from the outside surroundings.

20240215_170043.jpg


The stock cable of this set is somewhat average for its price given that I've encountered better stock cable from other sets. It has 4-core silver plated copper that was twisted with a 3.5mm termination plug that was gold-plated, although if I compare it to other sets, this one is on the leaner side. But still, it is quite supple and flexible to hold it.

20240215_165836.jpg


The product packaging of the Forteza is a medium-size one but it is fairly bulky as it accommodates its contents.

20240215_164753.jpg


Here are the following contents inside of its packaging box:

  • Pair of Kiwi Ears Forteza IEM transducers
  • Stock cable
  • a rounded square zippered carrying case
  • Three (3) pairs of white-coloured silicone ear tips in different standard sizes.
  • Three (3) pairs of black-coloured silicone ear tips in different standard sizes.
  • Three (3) pairs of transparent grey-coloured silicone ear tips in different standard sizes.
  • User guide

20240215_165104.jpg
20240215_165050.jpg


Regarding its power scaling, The Kiwi Ears Forteza is quite hard to drive given its impedance of 32 ohms. To my surprise, my LG phones will automatically activate the high impedance mode, so I surmised that its impedance rating is probably much higher as it was stated on its official specification. If it was amplified with decent power amplification in the state of low gain mode, it would not give us dynamics and texture as it sounds a bit underpowered and quite lean. Devices with medium gain or high gain mode are a must to be paired in this one.

20240221_213914.jpg


As for its tonality, the Forteza is clearly a V-shaped sounding one as it has more emphasis on lows and highs and a trough midrange just as the line of song that I put in the introduction.

20240215_165423.jpg

Kiwi_Ears_Forteza.jpg

(The frequency graph was provided by @baskingshark , credits to him)


LOWS/BASS:

This is the most prominent frequency of the Forteza as it has quite a boomy, authoritative and physical bass response. This bass quality and quantity harkens back to the late 2000s up to the mid-2010s where Beats By Dre, Skull Candy, Sol Republic and even V-modas cans rule the audio market aim for more consumer-friendly sound rather than a nicher Hi-Fi sound quality.

Its sub-bass presence is quite perceivable as I definitely feel its deep rumble and reverberations from instruments such as low tone bass guitars, drum machines, synthesisers and octabasses. Mid-bass on this one appears to have a warm, sufficiently textured and it definitely bleeds across the midrange. Bass guitars have weighty and earthy sound on every plucking, slapping and strumming on its strings while bass kick drums have thunderous and fullness on every kick although its a bit sluggish in fast double bass kicks on some rock and metal tracks, and then, the bass-baritones have heavy, voluminous and darker with a very full tone on their voices.


MIDRANGE:

The midrange response of this set is on a steep and recessed on its overall presentation as it sounds a bit distant despite the smearing of mid-bass response. Most vocals and instruments were noticeable behind in the mix. Despite its recessed presentation, it still has some texture on its note weight and somehow energetic sound for female vocals and string instruments.

Male vocals sounds quite textured and has a heft on it as baritones have rich and plush sound on their vocals, tenors have brassy, ringing and dazzling though I noticed that in some tenor types like spinto and dramatic ones seems a bit less emotive and rich sounding in my opinion but quite good on leggero and lyric types as they sound graceful and bright. Countertenors have a tender and smooth sound on their voices enough to project their unusual high pitch falsettos. On female vocals, contraltos have smooth and smoky voice quality but lack of heftiness and depth that its intended timbre should have that rich and dark tone. Mezzo-sopranos have rounder, tender and sensitive vocals as I find them sweet and melodious. Meanwhile, sopranos have that bright, full and metallic sound which quite suits all types of sopranos vocals albeit they might be too piercing and shouty to some listeners.

On instruments, strings like guitars and violins, a crisp and bright sound on guitars and a vibrant and metallic sound on violins. Then on woodwinds, piccolos have bright and penetrating sound, concert flutes have bright sound and also has penetrating sounding one too, clarinets have a shrill and lively sound, and then saxophones have reedy and forceful sound. Brass instruments such as trumpets, trombone and horns, trumpets have a brilliance with some hint of metallic sound while trombones have penetrating and tense sound, and then horns have bright and metallic sound that compliments well with other instruments in brass sections in an orchestral ensemble. On percussion instruments, snare drums have bright and shrill sound on every stroke while field drums have booming and sombre sound, Tom-toms have warm and resonant sound on every hit on its batter head, and kettledrums have booming and rumbly sound. Pianos appears to have a warm and uneven sound on them.


HIGHS/TREBLE:

Since that this set's frequency response has elevated upper-mids up to the brilliance part of the treble region which makes it a brighter and crisper sound but it might sound too intense to treble-sensitive folk out there. That accentuated upper-mids and presence part gives more pronounce and definition on female vocals and sharper attack on instruments. But in most cases, sibilance is quite evident and there are some instances of harshness in some tracks.

On the brilliance part of the treble region, it is quite sparkling with a fair amount of treble air. Cymbals have metallic, harsh and sizzling sound, hi-hats sound a bit exaggerated as it has more splashy instead a shortened buzzing sound, celestas have too much shimmering sound on them and glockenspiels have jingling, strident and piercing sound on them.


SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

The overall perceived sound/speaker stage dimensions on Forteza is on average to above-average as it has median width span, a good height ceiling and depth as it seems more proportional within my headroom.

Its stereo imaging is atypical two-dimensional presentation and locating a certain element like instruments or vocals seems decent as I was to pick it up in a soundscape. Separation of instruments is somehow acceptable while its layering is up to par but not that well-defined one that I want to.

The cohesiveness of its hybrid driver configuration isn't particularly impressive given that the dynamic driver that was implemented for bass response isn't that fast enough as the lows seems to be a bit sluggish. This set is quite resolving in terms of resolution capability as it has a solid macro-dynamics while it has sharp micro-detail retrieval as it is capable of extracting some nuances and details from an extracting albeit on overall tonal aspect, it sounds a bit unnatural and too digital sounding.


PEER COMPARISONS:

TANGZU FU DU VERSE I


● TANGZU's first hybrid driver configuration IEM. It has a single dynamic driver and two balanced armature drivers which is more of a contrasting driver implementation of FORTEZA, and it was encapsulated in a 3D-printed resin shell chassis with aluminium alloy faceplate. FU DU has high quality ear tips but FORTEZA has a better carrying case.

● Tonality-wise, FU DU has a U-shaped, balanced-warmish sound profile that makes it more balanced sounding and even a refiner one in my opinion, while its doesn't have a more authoritative bass response and brighter sound on FORTEZA, FU DU has a cleaner, well-balanced and smoother sounding and definitely not a hint of sibilance. Technicality-wise, they are quite a match in some aspects but separation and layering, the FU DU is better while FORTEZA has a sharper micro-detail definition due to its elevation on high frequencies.


CVJ MEI

● CVJ's hybrid set with Knowles BA driver, it has 1 DD + 2 BA set-up and it was encapsulated in a composite shell chassis. It is noted that it has toggle switches that makes this set more versatile. But in terms of inclusions, it is quite inferior to the FORTEZA from the quality of cables up to the carrying case.

● Due to implementation of toggle switches, MEI offers 4 types of sound profiles but I will compare this set to FORTEZA in 1 DD + 1 Knowles BA. Bass is more punchy and cleaner, midrange is more textured, balanced and cleaner, and then treble is more refined as it sounds smoother and less offensive sounding on MEI. On technical aspects, both sets are quite similar but MEI has better separation and layering a bit while FORTEZA is quite more resolving due to its micro-detailing definition.


ZIIGAAT CINNO

● ZIIGAAT's first hybrid driver model, it has a single 10mm LCP dynamic driver and four (4) balanced armature driver set-up and it was encased in a resin shell chassis, it doesn't doesn't have any storage case and a meagre amount of ear tips.

● CINNO has a mild U-shaped sound signature with a warmish-balanced tuning. Compared to FORTEZA, its bass response is a bit tighter yet cleaner while it has less recess on its midrange presentation and it has sufficient texture and vocals and instruments sound quite more organic sounding, and then smooth and a bit darker treble response. Technicality-wise, both have similar sound/speaker stage proportion, stereo imaging, layering and separation, but cohesiveness of its driver, CINNO is a bit better due to faster transient speed response while FORTEZA has more resolving and well-defined micro-detail definition.


To sum up my review on the Kiwi Ears Forteza it seems that they are trying to be different once again as they are having some throwback moments on delivering this set. The Forteza is truly a coloured sounding one that will give more listening satisfaction towards more consumer-oriented tuning which is simply more musical and doesn't really matter on more technical and tonally correct sound that caters more on critical-type of audio enthusiasts. If this set was released in the late 2000's, I might like its sound quality as it sounds a bit better to some cans that I've tested at that time. Again, if you are looking for a set which sounds fun, engaging and lively just to listen casually, this one is one of them that I will recommend.
