Abstract
Embodiments of this application disclose a noise reduction headset. A branch pipe is disposed in the headset to connect a sound cavity inside the headset and an external environment. The branch pipe has a low-pass filter function to filter out high-band noise entering the sound cavity from the external environment, so that impact on sound quality inside the sound cavity that is caused by noise in the external environment is reduced, thereby implementing passive noise reduction.
