Ergonomic Titanium Chassis

Shape of the chassis is created based on experience and multiple iterations. The design is based on up to thousands sets of ear shapes so to make it ergonomically sound.

The party trick of titanium alloy is that it is low in density and high in strength at the same time, and thus the chassis is quite lightweight. This characteristic of the material significantly lowers the chassis resonance, providing a much cleaner sound.

The surface is meticulously buffed. It's smooth to the touch while having an absolutely fantastic look.

Flagship Driver Combination

Acoustic engineers spent countless hours in experimenting with driver combinations before coming up with the final solution.

The main design goal is to let the drivers work perfectly in their respective frequency band.

Six-way Electronic Crossover Five Acoustic Bores

Six-way electronic crossover is put in place for precise performance. Each driver is chosen to mitigate the pitfall of timbre difference between drivers.

Each set of drivers has a separate acoustic bore and hand-cut to length. This safeguard removes any possible time alignment and phase issue that may arise.

Balanced Performance Fit For a Halo Earphone

Complex driver matching, crossover and acoustic bore tuning gave Cadenza 12 its voicing: a powerful overall sound across the spectrum. The flagship level of performance also allows the personality of upstream gears including cable and source to shine through in the final output.
