---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Model: Sealed dynamic type Driver unit: approx. 13.5mm Mass: Approx. 34g Power source: Lithium-ion rechargeable battery (built-in) Charging time: about 2.5 hours Model: Electret condenser type Directional characteristics: omnidirectional Accessories: Hybrid earpieces S, M, L (2 each), micro USB cable
