Here's a standard-structure, VC-funded, exit-oriented startup to consider: make video calls reliable. As in, you provide a guarantee and pay the customer if the call didn't work.
Wired headphones could be one part of the solution. They're just far more reliable (if they don't break, which they will). But if the reliability of video calls can be improved so that it's literally as reliable as talking to someone next to you in a quiet room, I bet lots of people would pay for it. There is so much latent frustration about unreliable calls, even with the best setup, even in NASA, in DoD, corporations, zoom and other platforms fail to perform reliably in so many cases.
Funny you mention it; I actually have been thinking of this as a startup/solution for ages (especially since covid). I realized that it's likely a fair bit more difficult (you'd need significant control of both software as well as hardware stacks.)
If you or anyone's seriously interested in pursuing it, feel free to reach out to the email address in my profile page.

Microsoft would be ruined, haha. Over the past week, I had about a 30% chance of the call not working and a a 80% chance of the screenshare not working
