I have a studio sitting in front of me on the desk at work - just anecdotically: if people in video conferences move away from THEIR microphone (if they are using e.g. a camera) it might be difficult to understand what they saying - particularly when they speak some accent 🙃 - but in my office the speakers are fine… having written that, I still use almost always headphones with an integrated mic and in the rare occasions I don‘t, yes, in comparision, the sound of the Mac Studio speakers is "awful"… but it works "fine"
