Miravia Item identifier: 1370477693112609-2087655468761377 Product Description: KZ-ZVX New flagship in unique dynamic field Pioneering electronic frequency modulation technology Takes the dynamic driver to a new height Acoustics is not metaphysics When the hardware is good enough Then the sound quality should be excellent Product Features ● 10mm dual cavity super-linear dynamic headphones: Brands that can write history will sell this type of dynamic headphones for over one hundred dollars. What we're doing is lowering the price so that people with different income levels around the world can enjoy true Hi-Fi without a financial burden. ● Unlike the same type of unit used in those expensive headphones, we've implemented several groundbreaking innovations based on this dynamic unit. ● Pioneering electronic frequency modulation technology, more precise, with less sound loss, unlike traditional damping structure tuning, lets you experience a new auditory feast brought by this new technology. ● Typically, the density of a damping element not only determines the tuning frequency range but also affects sensitivity, so traditional damping structure tuning cannot accurately control the target frequency. KZ's new electronic frequency modulation technology not only has more precise frequency control and tuning capabilities but also less sensitivity loss when adjusting the target frequency compared to traditional damping structure tuning. This new technology can precisely control and adjust the output across the entire frequency band, and implement any conventional-style FR curve in a single driver. (This adjustment method is completely different from traditional EQ sound effect adjustment because it doesn't adjust the sound through software, resulting in almost no loss of sound quality and eliminating the need for an external power supply.) ● Not only does it offer incredible sound quality, but it also boasts an amazing appearance design. At its price point, the VX features an all-metal casing, adhering to a high-end hardware process. From die-casting and CNC machining to grinding, polishing, electroplating, and laser engraving, every step is rigorously controlled to ensure a flawless overall appearance. All of the above makes ZVX a benchmark design model for similar products.
