Description
Kiwi Ears Cadenza II In-Ear Monitors
The Kiwi Ears Cadenza II represents a major leap forward in single dynamic driver IEM design. Engineered with a newly developed 10mm Titanium Dynamic Driver and powered by KARS 2.0 (Kiwi Acoustic Resonance System), the Cadenza II delivers deep, controlled sub-bass, lifelike mids, and clean, extended treble — all while maintaining a natural, fatigue-free tonal balance.
Designed for audiophiles who value precision, texture, and realism, the Cadenza II blends cutting-edge acoustic engineering with premium materials to create a refined, immersive listening experience across music genres.
Next-Gen KARS 2.0 for Pinpoint Sub-Bass Precision
At the heart of the Cadenza II lies KARS 2.0, Kiwi Ears’ advanced acoustic resonance system. This system introduces an 8dB sub-bass boost that cleanly rolls off at 200Hz, delivering a subwoofer-like low end without muddying the midrange.
Through a meticulously engineered labyrinth-style airflow network, KARS 2.0 achieves a level of bass texture, depth, and control rarely found in single-driver IEMs. The result is punchy, tight, and accurate bass that audiophiles crave.
Premium 10mm Titanium-Coated Dynamic Driver
The newly developed titanium-coated diaphragm combines rigidity with flexibility, enabling faster transient response and superior resolution across the frequency spectrum.
By pairing titanium with a PET base diaphragm, the Cadenza II achieves excellent clarity, improved micro-detail retrieval, and enhanced durability — delivering a sound that feels both powerful and refined.
Unmatched Tonal Balance & Natural Timbre
Carefully tuned for realism, the Cadenza II offers a neutral-balanced sound signature with subtle enhancements where it matters most.
-
A gentle midrange lift adds warmth and vocal richness
-
Smooth 3kHz treble tuning ensures clarity without harshness
-
Extended treble provides air and openness
This balanced approach makes the Cadenza II ideal for long listening sessions, whether you’re enjoying acoustic tracks, classical music, or modern productions.
Elegant & Durable Premium Construction
The Cadenza II features a polycarbonate composite shell paired with a CNC-machined aerospace-grade aluminum faceplate, finished with a subtle honeycomb pattern.
The lightweight shell ensures comfort, while the laser-engraved aluminum faceplate adds durability and a premium tactile feel — built to last, both sonically and physically.
Detachable 0.78mm 2-Pin Cable
Equipped with a detachable 0.78mm 2-pin cable, the Cadenza II allows easy upgrades and replacements.
The included single-crystal oxygen-free copper cable ensures clean signal transmission with minimal distortion, preserving the IEM’s natural tonal character.

Various reviews on the net created a lot of desire and interest to possess this iem.
Hitherto iv been buying audio gear from some other website who did not have this iem in stock.
Thought of buying from Audiostore.
I spoke to Mr Pritam and finalised the deal. Personal interactions do add up to the textual.content you gather from the net. Delivery was exactly as promised.
My first impression of the iem is Spectacular sound reproduction!!!
Songs thatIheardliterallyfelt like being played in front of me.
Bass sufficiently good enough for every listener except bassheads. Of course bassheads would lose considerable amount of ther sonic capabilities.
Soundstage wide and imaging is excellent. Inspite of good bass every instrument is distinctly clear and precise.
Only request for Audiostore is to include other leading brands like Fatfreq, Fiio, Ibasso etc.
My honest review these are best and luxury looking IEMS and I love them and they fit in my ear perfectly for me and I love them
This IEM sound really good for everyday listening. The Bass has a nice punch,Vocals come through clear and the overall sound feels balanced and enjoyable.They’re comfortable to wear for long periods and block out a decent amount of outside noise.Easy to carry around as it’s comes with a pouch and Great for Music,Videos.Definitely worth it for the price, and specifically thanks for audiostore team.❤️❤️.
The bass in these stays present and hits quickly. An easy term to describe the feel is cinematic bass. And it get loud very fast recommend use Low gain with high volume or High gain with Low volume. Prefer your your choice.
After 10 days of use, I feel I made a great upgrade from the 7Hz Elua Ultra. The main differences are that the Elua has laid-back vocals and sub-bass rumbling, while the STA Hi-End surpasses those limitations with good imaging, zero distortion at high volumes, and cinematic punch in the sub-bass.
Here is the detail review with help of claude to differentiate the same batch of IEM just at "ONE POINT"

looks good , Sound is balanced, you can listen music,watch movies and also good for gaming.Bass is good not that much punchy but does not muddy details . No distortion at Max volume .
At first use I have loved the sound and the fit of the iem so far the best budget iem I have ever used go for it guys value for money product.
The DAC has no hissing sound and the other shell is build of metal. great wire quality no heating issues as well. also the red light is menacing as hell. also case is included which is fine/cheap quality. also type a to c converter is also given in box.
This is a very comfortable IEM, I can wear them for hours without experiencing discomfort or ear fatigue. The shell are relatively small, very light and fits perfectly in my small ear. The eartips are also good and doesn't cause irritation in ear canal.
It is my first iem that i have purchased and it turned out to be the best decision ! I researched a lot before buying it as i am a bass lover. Finally bought KZ Duonic with switches c type. Every note is so clean and for every type of song it adjusts the sound. Delivery was before time and even the packaging was great! Thank you The Audio Store ❤️
After trying multiple ear tips, finally I’ve settled with Divinus Velvet ear tips along with Spinfit-W1. This is perfectly sealed for me and gives that great sounding with any of the IEMs I own. Recommended. Thanks audiostore
Its perfect no doubts there but the silver plated itself is high quality but wire built and the eartips are of low quality mic is clear and perfect.🔥👍
One of best Dac in upper mid range category, it has most powerful Sgm8262 amp along with Cs43131 successor dac. The Aura seamlessly connects with my iPhone 15 and my window Laptop. Sound quality omg what a mind boggling Sound I am getting through this with MoondropNice earphone. That's exceptional. Somehow it has connections issues with My oneplus nord 4 due to oxygenOS 15. May be it will sort out after oxygen OS updates.
ThanksAudiocular team .
I loved it , surprised totally. What a sound separation.
I was a bit sceptical about ordering it from The Audio Store as I order from Headphone Zone.
But great shopping experience with The Audio Store.
This is first time experienced IEM in ever I love this❤
Perfect fit with perfectly balanced soundscape for my personal liking and genres! Thanks a lot for audiostore!
