Poor audio quality causes what is known as Audio Fatigue
This is when poor audio quality actually causes pain to your listeners and will drive them away from your content. As a content creator you want your audience to be able to enjoy the content that you have taken your precious time to create. It is important to deliver to them with acceptable sound quality. You do not need to be an audiophile to have good sound quality this is a myth. With today's technology there are many affordable options to improve your sound immeasurably.
I demonstrate the difference between recording directly into my telephone into a $10 headset and into a $75 microphone which I'm running into a $200 interface.
