I don't think it's always said "mic feedback off, mic off" when I press the mute button on my actual headset though. I think that's changed in the last couple of weeks somehow. I know my headset used to only say "mic off" if I muted the mic. It's kind of redundant for it to say both. I can understand the "mic feedback off" prompt if you turn it off in iCUE, but it's obviously going to be off if you turn the mic off.
