Jabra Elite 75t earbuds have a noise-reduction mic that works great and the earbuds are more comfortable than any others I've tried. As far as their background noise, I think I'd just ask them to speak up and hopefully they'll clue in that the background noise is too much of a distraction. Another option might be messaging each other through an app like Slack if it's too hard to hear one another. I think most people are struggling to work from home right now. My husband's co-worker complained about a barking dog during a conference call, but it was the neighbor's dog that's three houses away and out of our control. I turned on a fan and my husband spoke louder and it seemed to be enough to at least discuss the next step in their project.
