Dual chambered beryllium coated DD - Cadenza4 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. Physical and electronic filtering - Cadenza4 adopts three acoustic tubes that are combined with an electronic four-way crossover. The 50μm 3D printed acoustic tubes ensures accurate, smooth, and consistent sound. The four-way electronic crossover allows for precise control of frequency distribution and significantly reduces phase errors. Lightweight earpieces - Cadenza4 once again collaborates with Heygear Technology to refine the earphone chassis. Ensuring comfortable long-term wear and enhanced durability. The panel is crafted from CNC aluminum alloy material with a matte finish which provides a delicate and textured feel. High quality stock cable - Cadenza4 comes standard with a 392-strands high-purity silver-plated monocrystalline copper cable, enhancing the fidelity of the sound. With three types of 90° interchangeable plugs,which significantly improves device compatibility. Cadenza4 melodies of enchantment The Cadenza4's goal was to achieve a warm, wide, and natural sound, faithfully reproducing every detail in the music. The engineering team went through multiple iterations during the development phase, ultimately achieving the flawless and authentic sound quality of Cadenza4.
