Kiwi Ears Quartet Review – Design and Functionality
After unboxing for this Kiwi Ears Quartet Review, we saw how stylish the Quartet is. It features purple swirls that contrast the black base of its shells.
We appreciate its subdued and non-gaudy appearance, although it does appear more vibrant when exposed to sunlight. However, it manages to introduce a delightful touch of colour.
The construction quality is exceptional for an IEM within this price category. Judging solely by its build, it would be challenging to distinguish the Quartet from the pricier models in the market.
Additionally, the fit was exceptionally comfortable, offering robust sound isolation without ever feeling obtrusive.
The Quartet incorporates a dual 10mm dynamic driver configuration. This setup allows the IEM to handle lower frequencies. It also has two balanced armatures dedicated to the high range.
This choice in design directly aligns with its model name. Compared to the distinctive hybrid arrangement of the Quintet featuring five drivers, the Quartet opts for a more straightforward approach.
Key Features of the Kiwi Ears Quartet
Harmoniously Balanced Sound
Although bass-centric, the Quartet aims to provide a natural tonal balance. The goal was to deliver an impactful, textured bass without dulling or muddying the midrange and treble.
These IEMs feature crossed-over dynamic drivers using a passive low-pass network at 350Hz. It enables the Quartet to produce thick, rich bass, while the midrange from 350Hz to 1kHz is flat. As a result, it offers an accurate tonality in the mids, like neutral studio monitors.
While testing the product for this Kiwi Ears Quartet Review, we recognised the warmth in the lower mids. It allows the IEM to deliver booming bass with clean, flat mids to prevent bloating.
Resounding Bass
The Quartet can accommodate the groundbreaking sobaric double dynamic driver subwoofer from Kiwi Ears. This pioneering driver design has the power of two 10mm titanium diaphragm drivers. Each of these has dual magnetic circuits to make them work.
These drivers are ingeniously aligned to ensure phase synchronisation. They help prevent any potential soundwave cancellation.
The innovative subwoofer design delivers extended sub-bass kicks. These are characterised by their tight, rapid, and profound resonance, surpassing the performance of earlier woofer designs.
The Quartet is a solution for individuals seeking a fun and high-quality IEM that meets all their bass requirements.
Custom Balanced Armature Drivers
While writing this Kiwi Ears Quartet Review, we noticed it has custom mid-high frequency balanced armatures. It also features customised ultra-high balanced tweeter armature drivers.
To ensure harmonious synergy with the new dynamic drivers, they underwent a modification that incorporated a finely tuned venting system. The process helps optimise airflow.
Keeping the practice of Kiwi Ears, the balanced armatures were skillfully adjusted. It is necessary to make it align with the in-house target curvature for both mids and treble.
As a result, the mid-treble range delivers a pristine and sharp tonal quality to both vocals and instruments. It steers clear of any hint of dullness or nasal resonance.
The high frequencies exhibit remarkable detail and an abundance of sparkle, making them suitable for professional applications. However, they remain true to a natural character and are devoid of shrillness or listening fatigue.
Recommended for Drummers and Bass Guitarists
You can consider the Quartet as a neutral studio monitor. However, these have bass and sub-bass emphasis starting at 350Hz.
The product offers more texture, body, and richness in its lower mids. Plus, it is ideal for bassists and drummers who need impactful and powerful lows.
While testing the IEM for our Kiwi Ears Quartet Review, we realised how beneficial the Quartet is for music enthusiasts. The reason is that the product offers quality-sounding bass that has natural tonality for excellent tuning balance.

Hands-on with the Kiwi Ears Quartet
This IEM’s stand-out attribute is its unparalleled bass, which is always warm and heavy. However, it exhibits an explosive and aggressive sound quality. The tuning makes the bottom mids a little muddy, but its output still stays clear.
In particular, their sub-bass frequencies sound great! The bass end also remains prominent even within the mid-bass region of the sound mix.
Nevertheless, the bass is really fulfilling; however, at times, its feels a bit bloated that overpowers the higher sounds on some tunes. The characteristics of this cloudy bass profile are also capable to smoky out the details and texture. Nonetheless, one can point out that stringed instruments have naturally-coloured sound, which means a natural timbre.
Quartet’s midrange tone tends to be a little mellow compared to neutral or flattened. Additionally, it feels rich on the palate without hiss or bitterness.
There is a notice of color in lower and upper mid ranges. To ensure that there was no muddiness, Kiwi Ears made some little tweaks on the Quartet.
The low-mid may sometimes get covered by the bass frequencies, yet they preserve the balance as a quartet.
You should expect a good deal of low-mid presence in regard to balance. It gives many bodies to the tracks and particularly if blended up with the warm low end. There is no vocal overload in the mix as well as in the mid-range which sounds good for listening.
Balance of overall balance, especially suitable for modern pop music or spare mixes. The fourth characteristic, unlike others, is unique and separate for lows and highs.
The treble tone in the Quartet is smooth and warm, just right. Consequently, it was not too dark nor loud. Additionally, it provides a slight feeling of spaciousness resulting into a clear representation within this frequency.
Tuning the high frequencies makes Quartet a non-fretting and comfortable iems to listen to.
They are suitable even for delicate people, who get disturbed by too much high-treble brightness.
High frequency is one of the features that we enjoyed while testing the product as stated in this Kiwi Ears quartet review. However, these soften the overall serious soundscape.
This range presents vocals as velvety and wind-like, while strings and wind instruments show they are most crystalline. A sparkling effect is offered by the top registers as opposed to an acute clarity.
Although, it’s not the brightest component, the treble has a snappy and modern flavor to it which gives the old music an innovative sound. Moreover, high treble response was sufficient, and there were no harsh or bright timbre issues that should have been avoided.G
With respect to Kiwi Ears Quartet, there is an acceptable treble, loudness, and amount. This has appropriate resolution for detailed retrieval that could be used in genres such as pop, rock, ambient, and hip-hop.
The kiwis ears quartet illustrates sufficient distance between the instruments and vocals. The soundstage has a good width with average depth and height.
Although the soundstage is not so wide, it offers a great imaging capability with distinct instruments spread in the soundscape. Consequently, it evokes an impression of space authenticity.
There is no great level in the stage which somewhat reduces the scales of a sound space. However, these are gradual variations in depth and height which occupy precise positions in the stereo field.
