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.

Customers praised the IEM's excellent sound quality with "strong sub bass," detailed mids, and "excellent sound stage." Many noted it's a great first IEM. However, some found stock tips uncomfortable and fit challenging. Switching to aftermarket tips like DUNU S&S significantly improved comfort and bass response for some shoppers.
- Sound stage is excellent, music separation and sub bass impact is magic
- Mids are where the iem shines, guitar cords, vocals feel separated
- As a newcomer i was afraid but its soo good man
As a newcomer i was afraid that will that would be harsh? But nuh its soo good man.
Sound stage is excellent, paired with the audiocular beam DAC, it just so good.
Both male and female voice standout, with music seperation and sub bass impact is magic
my first IEM, pretty good experience. delivered in 3 days
The Cadenza II's warm, musical, energetic character was obvious from the first listen but the stock wide-bore tips were genuinely uncomfortable for me, and I didn't realise how much that was holding the sound back until I fixed it.
Switching to DUNU S&S tips made a bigger difference than I expected, on two fronts at once. Fit-wise, the Cadenza II now sits far more securely and comfortably in my ear. Sonically, the improved seal brought back noticeably deeper sub-bass that simply wasn't reaching me before. Tracks that sounded good suddenly sounded complete, with low-end texture I hadn't heard at all with the stock tips.
The S&S tips don't change what makes the Cadenza II special. They just let me actually hear it. If you're finding the stock tips uncomfortable, don't assume that's just how the Cadenza II sounds, the right seal might be hiding half the performance.
I love this purchase of mine. Though me being analytical for it everytime definitely ruins my experience little bit but it from my side.
I really like the sub bass of it. That Rumbling i feel in my ear is pretty decent. Billie's Bad Guy sound so so good on this , because of the strong sub bass this iem have. Mids are where the iem shines , guitar cords , vocals feel separated even after stronger sub bass. Dholak , Tabla and bassy indian instruments sound equally good.
Fps gaming is decent on this , While i am not fps guy my friend tried it and he can sense footsteps even at low volume, it is very important because at higher volume gun sound really sounds prickly to ear. Moreover he was able to locate the opponent decently even at different floor on PUBG mobile.
I do have complaint about the overall fit of this iem. For my ear they are big , bit uncomfortable too. It also because of me pushing them all inside my ear canal for tighter fit.passive noise cancellation is pretty good on this iem.
