Thanks for listening.
It occurred to me that this wasn't a good angle of my performance in that the windscreen of the mic covers my mouth.
Overall, I'm happy with the CM311A.
I know that I'm not the greatest singer in the world, so my opinion doesn't hold a lot of weight. But I think that I have learned to sing better because I have a headset. I used to sing the higher notes much louder than the lower notes, and with the headset, I have learned to sing the higher notes just a little louder than the lower notes.
I like being able to look around the room while I sing or to have the crutch of being able to look at the keyboard or my fingers while I sing.
The vocal harmony setting, btw is Std Duet.
