Hey dude no offense but I believe it is a common sense that when you do a video specially what ifs than you should see the voice if people can listen to this voice clearly or not if they difficulty listening to this voice some people may adjust to it but some may not so that's why you should add a voice that all the subscribers could listen and satisfied with that voice so that like me they didnot voice this kind of complain hope you understand when you add voice than check the voice if it is understandable or not
