---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Driver unit: 40mm dynamic type/neodymium magnet Sensitivity: 102dB SPL(1mW) @ 1KHz Frequency range: 10Hz to 20,000Hz Impedance: 68Ω(1KHz) Accessories: 3.5mm to 6.3mm gold-plated conversion plug, 1m and 3m headphone cables, headphone cable clip, carrying pouch
