I would add to the reasons for "Use wired headphones or speakers" is that many (all? not sure) combination "bluetooth headphones with mic" hardware will bottleneck at the bluetooth link. You end up sounding like you're on an old landline (and incoming audio is equally low-fi).

I ended up using my bluetooth headphones just for incoming audio; and a dedicated mic on my desk for my speech. It improved both my voice and everyone elses' dramatically.
