Is there microphone and noise reduction?

Hello, each OWS is equipped with a dual microphone directional voice system, which uses directional acoustic wave integration technology to improve the call quality. oladance is an open earbud, so there is no ANC noise reduction. However, the external noise will be weakened by the sound inside the headset and there will be noise reduction during the call. Users will not be disturbed by external noise when using headphones.
