Been remote for ~6 years now. I've used my camera maybe a dozen times, tops, during that time.
+1 for investing in a good headset. Get something that completely covers the ears, and/or has some noise cancelling. I bought a Logitech gaming headset with a good mic and it's made a BIG difference, esp. on days where I'm on 4+ hours for calls.
Ironically, what matters most for your own audio quality is that other people use headsets — because feedback cancellation is an extremely difficult algorithm which often malfunctions, and if someone wears a headset that algorithm doesn't have to run.
But I'm shouting into the void about that. Most people won't adapt their behavior when it doesn't impact them personally.
