------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ The newly developed diaphragm installed in the driver is 80% thinner than the HE400 series headphones. In addition, we were able to achieve a wider frequency band and improve the ability to express details more quickly. In order to reduce weight and provide a comfortable fit, we have developed a new headband that uses a hybrid structure of aluminum and leather. With an ultra-thin diaphragm, innovative headband design, and thin yet strong aluminum, it has evolved in all directions. The detachable cable uses a 3.5mm terminal with an emphasis on reliability.
