The KZ Ling Long is engineered for audiophiles seeking a balance of advanced acoustic technology and refined design. It utilizes an open-back chamber design and an optimized XUN-6 external magnetic dynamic unit, which features a 0.15mm magnetic gap and a 4-layer thickened voice coil. This combination significantly increases air flux and flow rate, resulting in a hearing experience that is both transparent and natural. Its acoustic performance is built upon a high-order magnetic circuit system, providing a foundation for excellent sound quality. The micro-dynamic unit inherently excels in high-frequency performance, making it easier to vividly reproduce UHF details. Furthermore, the precise cavity structure enhances the dynamic performance of low frequencies, while the overall design ensures the voice remains sweet and warm, retaining instrument details in a clean and balanced manner. Beyond its sound engineering, the KZ Ling Long boasts a sophisticated build quality. The earphone chamber is crafted from pure aluminum alloy, giving it a minimalist aesthetic. Despite its robust construction, its net weight is only 18g, making it comfortable for extended wear. The inclusion of a CNC carved nozzle and a metal tuning mesh adds to its premium feel. For optimal sound transmission, the KZ Ling Long is equipped with a high-purity oxygen-free copper flat cable, ensuring high signal transmission efficiency. The unit is designed for versatility, featuring both a version without a microphone and one with a microphone. Its technical specifications include an impedance of 25±3Ω, a sensitivity of 103±3dB, and a frequency response spanning 20-40000Hz. The combination of an open-back design, advanced magnetic circuitry, and lightweight pure aluminum alloy construction makes the KZ Ling Long a compelling choice for those who prioritize detailed, natural sound without sacrificing comfort or style.
