------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ This is an earphone-type wired headset with a USB-A connection that uses a dual microphone noise reduction system to suppress surrounding noise and transmit clear audio. Even when you are concerned about surrounding noise, such as when participating in a web conference from the office, you can always participate with the microphone turned on without having to mute it. Equipped with both a microphone that picks up surrounding noise (environmental sound) and a microphone that picks up your own voice (call sound), it cuts out unnecessary noise and clearly transmits only the voice emitted from your mouth to the other party. It can cut up to -35dB of noise, so even if you're talking on the subway (80dB), the other person will hear it as if you were talking in a quiet library. Adopts a high-performance microphone unit with high sound quality and low noise, delivering clear audio that is easy to hear.
