Over Ear Headphones active noise reduction Wired Over Lightweight for PC

Description:

Front and rear dual microphone array pickups: the front microphone picks up the main sound to generate a sine wave and the cosine wave of the background noise picked up by the rear microphone is offset by the horizontal overlap, and the main noise is calculated and separated by the noise filter chip, to meet the teaching and test pickup requirements of weakening and filtering out background noise.
Front cardioid single-pointing microphone: adopts the heart-shaped angle pickup calculation technology. Only the main sound source is within the cardioid angle can be recorded, and the sound source outside the cardioid angle is weakened and shielded.
Embedded steel protection head beam: The steel sheet is embedded in the head beam to make the head beam stronger. It can be adjusted up and down freely according to different head shapes.
Protein-like three-dimensional earmuffs: It is a new type of composite biological cortex material, which is a kind of material that is closer to the texture of human skin. It is not worn, shaped and not collapsed, so that the ears are placed in the sound field of the horn.
Saliva-proof MIC sponge cover: It can prevent saliva from spraying into the microphone, preventing dust from invading the microphone and affecting the recording effect. At the same time, it can also filter the noise and sound waves to a certain extent, making the sound source of the recording clearer.
