The composite construction achieves a balance of lightness and rigidity that enhances transient response and analytical capability while reducing harmonic distortion. Paired with a high-performance N52 neodymium magnet, the driver system maintains dynamic control and detail retrieval throughout the full 20Hz–20kHz frequency range.                                                                                3-Color Ice Crack Scale Faceplate                The EI-01 faceplate is crafted from premium acrylic blended with natural mica powder and high-refractive glitter powder, formed through a special composite molding process. The finish presents a symbiotic dual texture of naturally translucent ice crack patterns and finely lustrous shell scales, giving each pair a distinctive, premium visual character. Available in three colorways, the faceplate combines artistic expression with the durability expected of a daily-use HiFi accessory.                                                                                0.78mm 2-Pin Detachable Connector Design                The EI-01 adopts a 0.78mm 2-Pin detachable connector, allowing the cable to be swapped or upgraded for different use cases. The cable core uses high-purity oxygen-free copper (OFC) conductors in a four-strand precision twisted and braided structure, effectively suppressing signal interference for stable audio transmission. A durable PVC outer jacket offers strong wear resistance and tensile toughness, ensuring reliable performance during daily use, gaming, live streaming and monitoring.
