@JamminJerry @shefoof There's a thing in control center that allows you to change the microphone mode from one of three options. Standard (default, kind of noise reductiony), voice isolate (tries to get rid of all things that are not voice), and wide spectrum (basically lets everything through). It's an icon in either the status bar or control center while you're on a call. Don't remember, haven't done it in a while.
