Number 2 is what everyone else needs to do. It's so annoying being on a call and not being able to hear people because they have a cheap microphone, or use the one in their laptop. Having drop-outs because they are on a bad connection, or more often WiFi doesn't help either. It all adds to the cognitive load.
Of course we all need to do the same for everyone else's benefit too :-)
