The explosion-proof Bluetooth noise reduction headset has two modes: noise reduction and monitoring. When the surrounding environment is noisy, the noise reduction mode can be turned on, and the headset will filter the surrounding noise, so that users can hear the sound in the headset more clearly. In the monitoring mode, the earphone will still filter the surrounding noise, but in this mode, the voice in the earphone will not be heard, but the voice of the surrounding people can be heard clearly. You can choose these two modes freely according to the actual situation.
