Kiwi Ears KE4

Costruzione eccellente e profilo audio di super qualità. Ideale per musicisti, professionisti del settore ed amanti della musica di alta qualità. Il doppio driver spinge bene i bassi senza sovrastare le altre frequenze. Ho ascoltato ogni genere musicale ed in ogni occasione ho potuto apprezzare i dettagli che con altre cuffie non avevo percepito. Per maggiori approfondimenti vi consiglio di guardare la mia recensione che trovate su YouTube.

Sin dudas es una de las mejores opciones en relación calidad precio! Estoy totalmente sorprendido y conforme con la calidad que brinda este in ear, la calidad es notoria en todo sentido. Felicitaciones por este producto

The overall sound delivery is warm, with a low-frequency bias.
Still, 2 DD make themselves felt, but although the bass plays a dominant role, it does not score in the middle.
The sub-bass shows its power by playing the infra-low 20 kHz.
It has decent pressure and scale.
A variety of tracks with an abundance of low frequencies sound voluminous in these headphones, with a truly subwoofer effect.
The bass dominates, but at the same time leaves room for other frequencies, without violating the integrity of the sound canvas.
The midrange frequencies feel slightly rounded and smoothed - this shows that the headphones have a bias towards musicality.
Instruments in the midrange segment have a softened sound.
Acoustic live instruments have melodiousness and friendliness, they will not cut with sharp attacks and will not pull you out of a pleasant immersion in music.
The upper frequencies are smooth, but they are not devoid of detail and intelligibility of percussion.
They are a little distant in the scene, probably influenced by the damper, which results in a non-stressed, but at the same time very pleasant sound.
The vocals have decent resolution, they are located inside the stage among the musicians, slightly moving forward to the listener.
The stage is ellipsoid, of medium size.

Headphones enchant with their sound in calm genres and awaken an emotional uplift in driving genres.
Kiwi Ears KE4 are suitable for long-term listening to music, and even at high volume they do not cause fatigue.
They play any electronic music very cool, and meaty metal sounds!

Great set, check out my review below

Meta tuning is good.

+ Well separated and cohesive U-shaped tuning
+ Deep and rumbly sub-bass
+ Lower midrange is well represented
+ Inoffensive but still well extended treble
+ Good balance of musical and technical
+ Comfortable fit and solid build quality

- Tuning might be too boring/safe for some
- Bass emphasis won't be to everyone's liking
- Vocals lack a little heart/soul/magic
- Accessories could be better for the price
- Soundstage could be more expansive

For weeks, I’ve tested brand new Kiwi Ears IEMs, KE4. The configuration consists of 2 Balanced Armatures(BA) and 2 dynamic drivers (DD), where the isobaric system was employed for DDs providing the low bass. On the other hand, 2 BAs take the mid and high frequency region.

The sound signature is a warmly tilted so that it’s a bit bassier but not overwhelming too much. Thus, the mid and high signals still own their substantial presence without masking. This characteristics give a delicate warmth.

It’s worth noting that the bass presentation is quite distinctive in comparison with conventional 1DD system. The isobaric woofer seemed to offer more refined coherent low frequency sound.

In design-wise, I love the face plate that shows off the brushed metal and high gloss finish on top. Depending on the lighting condition, its surface shines differently from matt brushed to glittering texture.

Most importantly, KE4 is easy to wear due to the ergonomic-3D-printed receiver shell. Of course, it’s made of medical-grade resin, providing extra comfort along with new ear-tips(called as ‘Kiwi Ears Flex Ear Tips’). In contrast with its black-colored shell, ear-tip stems are crafted with a solid metal.

I think the combination of faceplate, shell design, and stem/ear-tips make KE4 premium look and feel. In conclusion, Kiwi Ears KE4 is one of the highly recommendable IEMs in $200 price range.

Kiwi Ears KE4, in my opinion, for $200 they offer us the most top neutral and balanced tuning, and I think that now this is the best choice for this price if you like this neutral and neat approach to setting up headphones!

The midrange is the most interesting part about the KE4 i think.
The lower midrange has a tinge of warmth to them (you can see the tilt from 300hz to 800hz), with minimal bleed from the midbass. But the special sauce is in the upper midrange, where there’s now an anti-shout dip in the pinna gain region. This makes the vocals overall sounds a bit more distant and laid back. That dip would’ve yielded more bad results than good for the overall sound quality if it weren’t for the not-too-boosted midbass and lower mids, else it would’ve muddied up and veiled a lot of details.
Male vocals sound warm-ish, correct in tone, yet not enough heft to their voice. Deep baritone lacks that classic weighty or lush characteristic to them, evidently in Frank Sinatra’s “Fly Me to The Moon” and Michael Buble’s “Sway”
Female vocals sound...fine, still forward enough with good liveliness to their voice, but can lack a bit of body to them (definitely not dull or dead sounding though). The KE4’s type of tuning is more beneficial for female contralto, but not so much for the mezzo-soprano and soprano type.
Like when listening to “Best friend” – Kana Nishino, her voice still feels sparkly and emotional, but you still wish there’s just some more energy to her voice.
Or for example, the climax of the track “All by Myself” – Celine Dion from 2:30 onwards, that high note of hers doesn’t sound piercing or harsh or “scream in your face” at all, but very sweet and easy on the ears.
So all in all, both male and female vocals have quite balance and similar emphasis to their voices.
A perk of this type of midrange tuning of the KE4 is that you can turn up the volume really loud for the KE4 without feeling like the vocals are too at your face and harsh sounding. You can say this is a “cheat code” to solve that laid back, not enough energy vocal issue.
When listening to “Shivers” - Ed Sheeran, there's only a very minimal amount of sibilant and harshness, so there’s that.
Instruments have a decently natural timbre to them. I said ”decent” because 1/ certain instruments do lack a bit of note weight to them. Just a bit. But more importantly, because 2/ it does have a bit of a BA timbre to them. That is not surprising considering I can literally see the BA nozzle right below these nozzle filters. That being said, the BA timbre is very minimal and easy to dismiss at times.
Piano in “Time to love” – October and “Somewhere” – July sounds quite pleasant, natural in the tone yet lacking a bit of weight in the strike. It’s very gentle as a whole. In “Cold” - Jorge Mendes and “Merry Go Round” - Joe Hisashi, violins sound soft, smooth and velvety, and don't have any abrasiveness or roughness to the stroke. It has just enough warmth and resonance to set itself apart from many other instruments, but the higher register notes do lack a bit of brightness to feel more alive.

Kiwi Ears KE4

An amazing upgrade from Apple AirPods

After 60 days of use, they work perfectly well — the sound quality is very good. The only downside is that the cable needs some color coding to distinguish left from right when connecting them for the first time.

These are my first IEMs from KiwiEars and I am thus far quite impressed.
The build is solid and they are light, even if a little bulky for my smaller ears. The sound is smooth and non aggressive, suitable for long listening sessions. Bass and midbass are strong but not overbearing, the mid frequencies are particularly well tuned, smooth and clear. The trebles are present, perhaps a tad soft, which I like. All in all, I very much like these but am too new to the game to provide a real informed comparison.
I liked that this model has received recognition, as it is sooo difficult to sort through the literally thousands of IEMs available out there.
Only caveat, I have yet to find the perfect tips to fit my specific ear canals. This is the next step as they play such an important role in shaping the final sound, especially in the bass regions.
I also bought the CANTA model to use for more vocal focused music, but have not unboxed them yet. Will report on those further down the road, as well as after some comparison with a couple models from other brands I also splurged on. Recommended!

i think New Meta from here on end because the fidelity and warmth coming from this tuning is more in line with how I like my audio. I think the KE4 is under appreciated atm, and pretty soon people will start to hear about it more.

Produit arrivé dans les temps et non déçu de la qualité sonore + du tuning de ces iem. Vaut largement son prix

Good sound smoth detail

They are the best pair of IEM's Ive used and I can say they are 1000% worth it. Saving my hair from balding to....

I have tried almost all of Kiwi Ears earphones before and nothing sounds like the Kiwi Ears KE4.
In general, I can see why some people might like this a lot. It has a strangely immersive tuning that draws me. However, it is not flawless.
Female vocals don't sound sibilant/fatiguing, which is great. However, they can sound slightly more recessed and lack of "sparkle/air" on certain tracks. Yay and nay.
Snare drums don't sound sibilant but they may lack the "crisp" sound that I find myself craving for.
Bass has good depth and punch but it may not be good enough on certain very busy tracks.
I really like the faceplate design. The earbuds are light and fit comfortably but they may protrude slightly due to the shape of the shells.
The cable is fine, and the ear tips included look like the newest Flex ear tips.
I prefer the Kiwi Ears Earphone Carrying Case to the default carrying case included.

So the KE4 are pretty decent. The build quality, stock cable, and stock Kiwi Ears Flex Eartips are all very good. The sound signature is pretty close to Harman-ish. There is great sub-bass. The mid-bass is sucked out and the low to middle mids are flat/recessed. This creates a sound signature that is all sub-bass and upper mids (V or U shaped). I feel that the lack of mid-bass and subsequent drop in the lower mids makes the KE4 sound more shouty than I prefer (again, this is purely preference based).

Overall, these are a solid IEM. The tuning isn't agreeable to my preferences. Most folks that listen to or buy these will like them a lot (IMO). That being said, there are better hybrid driver options on the market for similar, if not lower prices (Simgot Supermix 4, Tanchjim Kara, AFUL Performer 5, Binary Acoustics Chopin, Tangzu Fudu, Seeaudio Yume II, etc.).
