【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Nano Titanium Ion Composite Diaphragm: The EI-01 features a 10mm nano titanium ion composite diaphragm manufactured by high-temperature compression molding using a composite of natural fiber pulp and nanoscale titanium material. This composite structure, which combines lightness and high rigidity, achieves excellent transient response and high resolution performance, while effectively reducing harmonic distortion. Furthermore, in combination with a high-performance N52 neodymium magnet, it delivers stable dynamic performance and fine detail reproduction across a wide bandwidth of 20Hz to 20kHz, providing rich and accurate sound expression.
Three-Color Ice Crack Scale Faceplate: The EI-01 faceplate is made from high-quality acrylic blended with natural mica powder and high-refractive index glitter powder, finished using a special composite molding process. The natural transparency of the ice crack pattern harmonizes with the delicate luster of the shell scale texture, resulting in a unique and high-quality design. Each pair has a distinctive and premium appearance, enhancing its visual appeal. Available in three color variations, it combines highly artistic design expression with the durability required of a HiFi accessory for everyday use.
0.78mm 2-Pin Detachable Connector Design: The EI-01 features a 0.78mm 2-pin detachable connector, allowing for cable replacement and upgrades according to your application and preferences. The cable conductor uses high-purity oxygen-free copper (OFC) and a 4-core precision twisted braid structure to effectively suppress signal interference and ensure stable audio signal transmission. Furthermore, its highly durable PVC outer sheath provides excellent abrasion resistance and tensile strength, delivering reliable performance in a wide range of applications, including everyday use, gaming, live streaming, and monitoring.
Two Configurations, Two Options: The EI-01 comes in two versions, a 3.5mm version and a USB-C version, to accommodate various devices and usage scenarios. The 3.5mm version features a 4-core cable configuration with 32 x 0.05mm high-purity oxygen-free copper (OFC) for pure analog signal transmission. It is suitable for music listening, live streaming, and monitoring applications. The USB-C version uses a 12 x 0.08mm high-purity oxygen-free copper (OFC) cable and incorporates a KT02H20 decoding chip. It supports plug-and-play with UAC2.0 compatibility and supports lossless digital audio playback up to 384kHz/32bit. The USB-C cable also features a high-performance HD microphone, supporting calls, voice recording, and voice communication during gaming.
Skin-friendly resin shell, ergonomically designed for comfortable wear: The EI-01's shell is made of a skin-friendly resin material that is lightweight, highly rigid, heat-resistant, and moisture-resistant. The ergonomically designed in-ear shape fits naturally into the ear canal, providing a stable and comfortable fit even during prolonged use. In addition, its compact and ultra-lightweight design makes it comfortable to use in a wide range of situations, from listening to music at home to commuting, playing games for extended periods, and live streaming.
