Dual chambered beryllium coated DD:
Uses a proprietary 10mm dual-chambered beryllium coated dynamic driver, which possesses the characteristics of being light and extremely rigid. It significantly improves response speed and is easier to drive while reducing nonlinear distortion.
Knowles + Sonion BA Drivers:
The combination of Knowles and Sonion balanced armature drivers which makes the Cadenza4 to be packed with resolution, rich in mid-frequency details, and ample treble extension. The array of three high-performance balanced armature drivers leverages the strengths of each unit, precisely capturing the nuances of sound.
Nanometer 3D printed acoustic tubes and 4-way electronic crossover:
Cadenza4 adopts a solution with 3 acoustic tubes and 4-way electronic crossover. With a cutting-edge 3D printed 50μm acoustic tube, the engineers made sure it is calibrated to recreate accurate, smooth, and consistent sound. The four-way electronic crossover allows for precise control of frequency distribution and significantly reduces phase errors.
High quality copper cable: comes standard with a 392-strands high-purity silver-plated monocrystalline copper cable,preserving the earphones’ acoustic energy with minimal loss.
