ELECOM Wired USB Dual Microphone Noise Left and Right Microphones Can Be Mute and Volume Adjustment Black Headset, Connection, Reduction, Used,

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. This USB wired headset is equipped with a dual microphone noise reduction system that suppresses surrounding noise and allows clear audio transmission. Even in situations where surrounding noise is a concern, such as when participating in a web conference from the office or home, you can have a conversation without worrying about the other party. Equipped with two microphones: one that picks up surrounding noise (environmental sound) and one that picks up the voice from the mouth (call sound), and a dual-mic noise reduction system that processes the sound with DSP, cuts out unnecessary noise and clearly transmits only the voice emitted from the mouth to the other party. With a maximum noise reduction performance of -35dB, even when you are talking in a noisy environment such as inside a subway car (80dB), the other party can hear it as if you were talking in a quiet place such as a library (45dB). Adopts a high-performance microphone unit with high sound quality and low noise, delivering clear audio that is easy to hear.
