  Noise cancelling headset with mic for phone  have become more and more popular nowadays. To achieve good noise-cancelling effects, noise-cancelling headphones are faced with many challenges. Among them, how to correctly select a microphone is important basic work.   The purpose of this article, issued by Addasound, is to help readers choose the correct microphone to achieve better headphone noise-cancelling performance. Surely, it can also help you better understand the principle and implementation of noise-cancelling headphones.   Introduction of corded noise-cancelling headphones   When the ambient noise frequency is (<1 kHz) low frequency, passive noise cancellation technology cannot provide the ideal effect. Active Noise Cancellation (ANC) eliminates the original noise by picking up noise signals and generating "inverted noise" signals to achieve real-time noise cancelling. Current wireless headset with microphone noise cancelling basically uses this te...
