Audio is one of the most important things in video
When the audio is bad I often stop the video
In all honesty I can watch a video that is not perfect for the image quality, but if the audio is bad I’m out.
For years I’ve been using a Sennheiser wireless lovelier microphone. I always bring this to shows and use it during almost all videos and live streams, and it just sounds awesome and it never failed me. But it’s expensive, and for most starting creators it will be overkill, plus in all honesty you always have to put the wireless transmitter somewhere, and it’s not a super small device, plus over time I’ve had several cables replaced.
