Resounding Bass

The Kiwi Ears Quartet was designed around our new sobaric double dynamic driver subwoofer. The innovative driver design utilizes two 10mm titanium diaphragms drivers, each independently driven by dual magnetic circuits. The pair of drivers were passively aligned to be phase synced and prevent soundwave cancellation. This new subwoofer design emits extremely well extended sub-bass kicks that are tighter, faster, and deeper than any other previous woofer designs. The Quartet is Kiwi Ear’s answer for all those who want a fun in-ear monitor that will provide all the quality bass one could need.

Harmonious Balance

Although the Quartet is a bass-centric IEM, we still aimed to provide a natural tonal balance. This goal was centered around the need to provide a textured and powerful bass, but without any muddying or dulling in the mids or treble. The dynamic drivers were crossed over using a passive low-pass network at 350Hz to allow plenty of rich and thick bass, while the mids from 350-1kHz were tuned to be completely flat.

This allows an accurate tonality in the mids like that of neutral studio monitors, while giving a hint of warmth in the lower mids. This means the Quartet will sound thunderous in the bass, but still clean and flat in the mids, preventing unwanted bloating found in most earphones. 

Custom Balanced Armature Drivers

The Quartet features a custom mid-high frequency balanced armature and a custom ultra-high tweeter balanced armature drivers. These drivers were modified to fit the balance of the new dynamic drivers by a tuned venting system to provide more airflow. Following Kiwi Ears’ tradition, the balanced armatures are passively tuned to fit our in-house target curvature for the mids and trebles. This means the mid-treble provides crisp and clean tone to vocals and instruments, without sounding either dull or nasally. The highs are detailed with plenty of sparkle for professional performance usage, but are natural and free of shrillness or fatigue. 

Recommended Usages

The Quartet can be thought of as neutral studio monitors, but with sub-bass and bass emphasis beginning at 350Hz. This provides a little bit more of body, texture, and richness in the lower mids, but neutral mids and upper mids. The Quartet is perfect for performance drummers and bass guitarists who require powerful and impactful lows. Music enthusiasts who want quality bass but a natural tonality will also benefit from the Quartet’s tuning balance.

UNDERRATED

This set is great for many reasons but I was mostly impressed with how it did in first-person shooter video games. The technical capabilities of the Quartet really enhanced the experience of my gaming sessions. Also the shell is gorgeous, highly recommend.

Unos buenos auriculares

decir que estos Kiwi EARS QUARTET me han encantado, pero muchoooo… mucho!!
Puedes usarlo como monitores de estudio, con sub-bajo y énfasis en frecuencias por debajo de 350Hz.
Esto te proporcionará un poco más de cuerpo, textura y riqueza en los medios inferiores, pero con unos medios neutros.

Son perfectos también para baterías y bajistas que requieren bajos potentes e impactantes.

Pero, igualmente los amantes de escuchar una buena música que quieren unos bajos de calidad pero una tonalidad muy natural también se beneficiarán del equilibrio del diseño sonoro de este modelo QUARTET.

Así que si estás en alguno de estos grupos, te los recomienzo al 100%, yo estoy usándolos casi todo el tiempo que puedo llevar auriculares con cable. Y si ya tienes un amplificador o DAC AMP, les vas a sacar todo su jugo como a todos los auriculares con cable.

Decir una vez más que los auriculares con cable siguen siendo muy superiores a los auriculares bluetooth, aunque cada vez esa distancia se va a cortando, de momento unos auriculares IEM como estos sonarán mucho mejor que unos EarBuds bluetooth, por muy buenos que sean.

Y por decir alguna cosa a mejorar, que siempre la hay, quizá su escena sonora, no es muy amplia, les han dado algo de libertad de aire, para que la separación instrumental y la escena crezca, para que el sonido respire, pero quizá todavía esta es la parte que podría mejorar en este modelo QUARTET. Aún asi, estoy siendo muy detallista, porque para mi tienen un sonido increíble y divertido con sus graves potentes, peeero, ahí está ese detalle a pulir un poco todavía.

Kiwi Ears Quartet, fun with Bass-centric sensation

Thank you Linsoul. Kiwi Ears Quartet gives me the experience of listening to music with a fat, muscular and fierce mid-bass sensation. The vocal presentation with the balanced armature driver is pleasant. Instrument sounds in both the midrange and treble are presented well.

Style and power

I'll start by saying the shells are beautifully crafted, and very comfortable. Isolation is excellent once properly fitted. Sound wise these are smooth and rich sounding, The bass is deep and controlled. Midrange is warm lush and pleasant. Treble has a good extension and sounds very natural. Soundstage is accurate.

KIWI EARS QUARTET: FOUR SONIC PROFILES FROM QUAD DRIVERS

This is my second product review for Kiwi Ears as I previously did a review on their first single dynamic driver in the entry-level category, The Cadenza. This is Kiwi Ears Quartet and it is a hybrid driver set-up IEM with toggle switches for different types of tuning. How will the Kiwi Ears Quartet be able to compete with other sets with similar features?

PROS:

△ Beautiful and well-crafted acrylic resin shells.
△ Quite lightweight and probably has one of the best UIEM-style shell form factor when it comes to fitting and comfort as it snugs well into my lugholes.
△ Working toggle switches.
△ Good quality stock cable.
△ A plenty amount of ear tips to choose from
△Good quality IEM carrying case for stowage.
△ Easy to amplify as it scales well to all known sources.
△ A warmish U-shaped sound signature that will be likeable to majority type of casuallisteners.
△ Robust bass response.
△ Warm and textured midrange
△ Smooth and relaxed treble register.
△ Analogue-ish tonality the will gives a more pleasant and engaging listening experience.

CONS:

▽ Occurrences of mid bass smearing across to other frequencies due to its boomy nature that it sounds a bit bloated.
▽ Will not give a lively, vibrant and energetic sound on sopranos and tenors
▽ Too warm sounding in my preference on sound quality.
▽ Overall mediocre technical performance.
