Nano Titanium-Ion Composite Diaphragm The EI-01 is fitted with a 10mm nano titanium-ion composite diaphragm, high-temperature compression molded from a compound of natural fiber pulp and nano-scale titanium material. 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. Two Configurations, Two Choices The EI-01 is available with a 3.5mm or USB-C connector to suit different devices and scenarios. The 3.5mm version uses a four-strand 32×0.05mm OFC cable for pure analog transmission, well suited to music playback, live streaming and monitoring. The USB-C version features a 12×0.08mm OFC cable with a built-in KT02H20 decoding chip, supporting digital lossless audio at up to 384kHz/32-bit with UAC2.0 compatibility for plug-and-play operation. The USB-C cable also integrates an HD microphone for calls, voice recording and gaming communication. Skin-Friendly Resin Shell, Ergonomic Comfort The EI-01 shell is made from skin-friendly resin, chosen for its lightweight properties, high rigidity, and resistance to heat and moisture. The ergonomic in-ear shape conforms naturally to the ear canal, providing a secure and comfortable fit during extended wear. Its compact, ultra-light construction makes it equally suitable for home listening, commuting and long gaming or streaming sessions.
