The level of absolutely bogus assertions coming from the uninformed or misinformed about technology is staggering.

I'd have filed the information and then verified the bandwidth claims. The claim sounds highly unlikely.

Perhaps they were mistaken.

OK, I've been using the phone for audio, if I switch back to the mike, what is your prediction?

I'll try it out on Monday.

Just because people say it's "taking up their bandwidth" doesn't mean that's what's actually happening.

It might be causing some other kind of issues but a microphone can't really "take up someone's bandwidth"... That's not really how things work.

I have a fancy microphone, but when I’m away from home in a low bandwidth situation I often phone in audio to zoom because it lags less. Lagging video and non-lagging audio seems to bother people less than both lagging.
