Unmatched Bass Precision with 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.

Titanium-Coated Diaphragm Driver

To maximize technicalities and sound quality, Kiwi Ears developed a new dynamic driver. The addition of a new titanium-coated polyethylene terephthalate diaphragm combines the strength of titanium with the fluidity of polyethylene terephthalate. With a new powerful magnetic array structure, this dynamic driver provides the highest technicalities and resolution among Kiwi Ears’ dynamic drivers so far.

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. Kiwi Ears is proud to make a premium audio experience available to all.

Lasting Durability

To showcase its 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.
