Kiwi Ears Étude is one other fascinating IEM from Kiwi Ears, which has been releasing great-sounding and revolutionary IEMs just lately.
My expertise with Kiwi Ears IEMs started a 12 months in the past, once they launched the Kiwi Ears KE4, which departed from the usual tuning fashion of the time, often known as Harman tuning, and launched Meta tuning as a substitute.
It addressed the complaints of many individuals in regards to the Harman tune, which incorporates an elevated higher midrange, an absence of midbass and decrease midrange, and generally a perceived lack of higher treble because of the elevated higher midrange.
What’s particular in regards to the Kiwi Ears Étude is the inclusion of a vibration unit they name the Kiwi Vibration Transducer, or KVT. It produces shell vibration at the side of the music, which might be felt within the ear, including an additional dimension to the music listening expertise.
Competitively priced at $119, I’m wondering the way it compares to different equally priced, in addition to costlier and cheaper IEMs, such because the Kinera Celest Plutus Beast, LETSHUOER Cadenza4, and CVJ Shadow Blade, respectively. Let’s discover out in my full overview beneath.
Options
Kiwi Ears Étude is a tri-brid IEM that makes use of three sorts of transducer expertise.
It includes a 10mm Beryllium-Plated Diaphragm Subwoofer that operates beneath 250Hz, a balanced armature driver for the midrange, two balanced armature drivers for the treble, and a vibration driver often known as the Kiwi Vibration Transducer.
The 3D-printed shells have tuned acoustics that sing at the side of the vibration transducer, making the usage of the vibration transducer more practical.
I can hear the acoustic sound of the shells after I bump them collectively; they make a humorous sound.
One of the crucial essential options I’d like to say, however typically ignored in different critiques, is the inclusion of a correctly working strain launch system for the ear canal.
I hate it when my listening enjoyment is ruined by strain buildup and fixed modifications in air strain in my ear canal, which trigger nausea throughout strolling workouts on an in any other case great-sounding IEM. The Kiwi Ears Étude doesn’t have that challenge.
Design
The Étude has a barely above-average dimension and a snug shell however is below-average in weight.
It weighs 5 grams, which is 1.5 grams beneath what I contemplate the typical weight, 6.5 grams. The light-weight is because of the hollowed-out, acoustically tuned shell.
A gorgeous-looking faceplate covers the again of the shells, that includes a silver metallic edging, an artsy stripe sample harking back to the floor of planet Jupiter, and the metallic Kiwi Ears brand at its heart.
I like how Kiwi Ears spent sources in making the IEM look good, contemplating its entry-level value and revolutionary use of varied driver applied sciences. As a substitute of constructing a lot effort to make the packaging and equipment look costly.
Which brings us to the inventory cable. The included non-modular 4-core cable has good construct high quality, that includes steel elements, however makes use of skinny wires that may tangle simply and don’t match the aesthetic of the IEM faceplate as effectively.
Fortunately, cables are straightforward to interchange, and there are many IEM cables priced below $15 that function thicker wires and a greater look.
Consolation & Isolation
The Kiwi Ears Étude includes a barely above-average however nonetheless snug nozzle width of 6.3mm, and when mixed with the included ear ideas, it supplies a safe grip on the ears.
I attempted a vigorous strolling train, and I by no means felt it need to fall off; I don’t have to re-adjust it typically. It’s also straightforward to seal. I simply put it in my ears, and I’ve by no means had a tough time sealing it; it’s correctly sealed with none effort.
The Étude options an ergonomically formed shell that by no means applies concentrated strain to any a part of my ears, which might trigger discomfort over time. It feels very snug throughout lengthy listening classes.
Exterior sound isolation is common, akin to that of different IEMs I’ve tried just lately. The identical isolation I noticed with different IEMs after I go to a espresso store to loosen up. Nothing outstanding and nothing to complain about.
Packaging & Equipment
It’s good to see producers save on packaging and make investments extra in making the IEM sound and look good. The packaging of the Kiwi Ears Etude is environment friendly and easy, consisting of a black inflexible field with a graphics-laden sleeve.
The bundle features a person’s handbook, a guaranty card, three units of ear ideas, a cable, a carrying case, and a pair of IEMs.
Sound Impressions
I used a mixture of completely different sources with drastic variations in functionality and sound signature to see how the supply pairing would behave with the Etude’s very low impedance of 5Ω, as a substitute of the 32Ω customary for almost all of headphones and IEMs obtainable.
Other than the standard sources that I take advantage of for IEM critiques, together with the LETSHUOER DT03, iBasso DC-Elite Dongle DACs, and Shanling M3 Plus DAP, I added a small tail dongle DAC and my outdated Samsung USB-C to three.5mm adapter, which I bought as a freebie with a telephone buy a few years in the past.
Goal Impressions
Kiwi Ears Etude’s measured graph exhibits a wonderful channel steadiness, regardless of its five-driver-per-channel setup, indicating a excessive manufacturing customary.
The bass enhance is barely targeted on sub-bass frequencies beneath 60 Hz, with minimal impression on mid-bass frequencies, leading to a quick, clear, and deep bass response.
These peaks, centered at 200 Hz, correspond to the resonance frequency of the Kiwi Ears Vibration Transducer, or KVT.
They don’t sound as unhealthy as they appear; they aren’t apparent and solely manifest as felt vibration within the ears relatively than an audible bass increase in that space.
Kiwi Ears Etude has a really easy midrange and treble response; the pinna acquire peak, which is important for making IEMs sound pure, is simply a gentle 7 dB.
The treble is easy with a gradual hump centered at 8 kHz. And delicate bumps above 13 kHz, which ought to solely add air and never brightness.
Subjective Impressions
I accomplished my customary 24-hour burn-in for IEMs by leaving it enjoying with a spare DAP, and I saved busy with different issues, checking in periodically. I seen that the sound didn’t change a lot after the burn-in, and I can safely say a two-hour burn-in would suffice.
Of the three sorts of included ear ideas, I used the black ideas as I discover them the smoothest sounding.
I used each PowerAmp and UAPP music participant Apps because the supply music participant. I didn’t use any sound equalization, filters, sound area, or different sound enhancement options. Music was performed with none non-essential processing.
I might have used the included cable, however sadly, it has a 3.5mm plug. I have to use a 4.4mm balanced connection to have equality with the opposite IEMs within the overview, which the Etude can be in comparison with.
I used a third-party cable, particularly the Enterprise Electronics VE Dic Vita Cable, which is a 4.4mm cable.
The very first thing that got here to thoughts relating to the sound of the Kiwi Ears Etude was the readability of midrange, treble, and vocals, with out rendering the tonal steadiness skinny.
It has a really balanced sound power, starting from sub-bass to higher treble, leading to a wonderful total tonal steadiness that may be a delight to hearken to.
Étude has a barely V-shaped impartial sound signature, characterised by deep bass, a clear and clear midrange, and an brisk but non-fatiguing treble that’s brimming with power and element.
Bass
My first and final impressions of the bass are that it’s virtually impartial with solely a modest quantity of sub-bass enhance. Sub-bass is extra elevated than mid-bass. It doesn’t overwhelm the musical expertise; as a substitute, it’s well-balanced with the midrange and treble.
Étude’s bass has wonderful articulation, velocity, extension, and particulars, which I attribute to the near-neutral tuning. Nevertheless, the average enhance within the sub-bass ensures that the bass by no means sounds skinny or missing weight and impression; it sounds highly effective when the music calls for it.
It has an excellent quantity of power, stopping the musical expertise from being boring. The bass is effervescent with managed enthusiasm, creating an interesting sound expertise with out sounding muddy. It responds shortly to dynamic modifications within the music.
Kiwi Vibration Transducer (KVT)
KVT provides a perceivable and nice vibration to the music, particularly at louder volumes. It provides one other layer of bass to the musical expertise that can’t be achieved with out it. However sufficiently subtle to not spoil the excellently tuned tonal steadiness and sound signature of the Étude.
I seen an added presence within the mid-bass, particularly on electrical drums on some ’80s music, making them extra palpable.
It has good velocity, so it doesn’t decelerate the dynamic driver; the impact is extra felt than heard. It’s effectively calibrated that I didn’t want to flip it off, in contrast to the opposite IEM on this overview with a vibration unit, which I generally want I may flip off.
Midrange
By limiting the response of the dynamic driver as much as 250Hz solely, it leaves the balanced armature to breed the midrange, which it does an exemplary job, making the midrange sound so clear.
Because of the inherent velocity of balanced armature drivers, the decrease midrange doesn’t sound overly thick or muddy; it sounds clear and luxurious. Nevertheless, its average pinna-gain or higher midrange elevation prevents it from sounding skinny.
Kiwi Ears did a terrific job in tuning and balancing the midrange response; there’s by no means an excessive amount of or too little of something, permitting the music to move via with superb transparency. If I had been to design my very own IEM, that is how I might tune the midrange.
Treble
Detailed, dynamic, easy, and ethereal. It’s barely elevated in response, however by no means tilts the nice tonal steadiness. It’s clear, uncongested, and by no means fatiguing, with good macro and micro particulars.
The balanced armature drivers used are of superb high quality; regardless of their elevated response, they by no means sound metallic or low-cost, they usually exhibit superb cohesion with the remainder of the audio frequency vary. There isn’t any inter-driver coherency challenge.
Étude’s treble has superb velocity, it retains its readability even at loud quantity ranges, and there’s no congestion even with very complicated music; devices are effectively resolved by the Étude’s treble.
I have to say that the treble tuning of the Étude is superb and tastefully accomplished.
Soundstage
Étude’s soundstage is vast open and deep with good peak. It has a pure and atmospheric really feel that doesn’t remind you that you’re listening to an IEM. It sounds much like open-back headphones with nice sound staging.
The soundstage dimension is definitely above common and spherical, with roughly equal peak, width, and depth. Permitting good holography of the pictures. Nevertheless, the imaging efficiency is just not as outlined as the perfect I’ve heard.
There are sound directional cues indicating the place the pictures are coming from, however they aren’t as exact as the perfect, nor are they diffuse. The pictures are simply locatable, however the edges should not probably the most outlined.
Étude sacrificed a bit imaging efficiency for larger sound staging and tonality, which, for my part, is a wonderful trade-off.
Instrument layering and separation are wonderful even when enjoying loud. There may be barely noticeable degradation on this regard when evaluating low and loud volumes; the sound stays constant, indicating low driver distortion, an excellent dynamic vary, sufficient energy dealing with, and adequate headroom.
