Grounded sound on recordings

Hi everyone,

I’m currently encountering a buzzing sound on my vocal recordings, like grounded sound. I encounter it when I playback the recordings. the microphone sounds fine when not recording. But when the recorded voice is being listened, it seems airtight and not clear, sounding too loud and broken even if you try to lower the volume of your voice (it is obvious in the bandwidth that appears in the track, it sees to occupy the whole space). What’s seems to be the problem? Thank you
