KARS 2.0
The Cadenza II unveils the next generation of Kiwi Acoustic Resonance System: KARS 2.0. Since its debut, significant optimizations have been made to make KARS 2.0 more efficient, better integrated into the acoustic structure, and more precisely tune the low-end. With KARS 2.0, the Cadenza II features pin-point sub-bass tuning, showcasing a powerful 8dB bass that precisely cuts off at 200Hz for a clean, true subwoofer-like lows. New to KARS 2.0, the low-midrange has also been delicately tuned, allowing a 300~400Hz bump that adheres to modern tuning preferences and providing lush uncolored warmth in the mids.

Kiwi Acoustic Resonance System (KARS)
KARS is not a gimmick - it’s a physical lowpass crossover system that manipulates airflow to the driver, regulating low frequency output. This patented innovation features an elaborate labyrinth tubing network built into the shell. With scientific and computational calculations, the exact length, diameter, and angles have been modelled to perfectly calculate the crossover point for each dynamic driver. KARS makes possible a tight sub-bass shelf that has been previously impossible in a single-driver IEM. The bass quality, quantity, and texture is incomparable to any other crossover strategy used in a similar driver format.

New Titanium-Coated Diaphragm Driver
To maximize technicalities and sound quality, a new dynamic driver has been developed. A new titanium-coated polyethylene terephthalate diaphragm, which combines the strength of titanium with the fluidity of polyethylene terephthalate was developed. Combined with a new powerful magnetic array structure, this dynamic driver provides the highest technicalities and resolution among Kiwi Ears’ dynamic drivers so far.

Unparalleled Tonal Superiority
The goal for the Cadenza II was to present the ultimate tonal balance and technicality for all audiences. The Cadenza II was painstakingly tuned, first redesigning KARS 2.0 to match the new dynamic driver, with adjustments at the micrometer scale to perfectly tune the subbass. The midrange required a slight hump to bring out vocal warmth and lushness, which perfectly balances neutrality without being sterile. The treble peaks perfectly at 3kHz - a feat requiring us to go back and redesign the acoustic structure of the driver itself. The treble decay is smooth and extended. All of these features are achievements that have previously been never seen before in a single dynamic driver IEM. We are proud to make a premium audio experience available to all.

Premium Construction
To showcase its premium sound, the Cadenza II had to look and feel as elegant. The shell material has been upgraded to a durable polycarbonate composite, which is stronger than typical resin or plastic, while offering a lush velvet-like texture to the touch. The faceplate is CNC machined from aerospace-grade aluminum and laser engraved to achieve a subtle, yet distinct honeycomb design.

Detachable Cable System
The Cadenza II comes equipped with a 2-pin 0.78mm detachable cable system. Composed of single-crystal oxygen-free copper wires, the cable allows noise-free crystal clear signal transmission. You can mix and match different cables with the Cadenza II to fit your preferences, as well as extend the longevity of the IEM.
