---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- [Impedance (headphones)]: 110Ω±20% [Maximum input]: 20mW [Format (microphone part)]: Condenser type [Directivity]: Unidirectional [Frequency band (microphone part)]: 100~8000Hz [Impedance (microphone part)]: 2.2KΩ [Input Sensitivity]: -40dB±3dB(0dB=1V/Pa, 1KHz), -60dB±4dB(0dB=1V/ubar) Please check the Sanwa Supply website for product support and details.
