I thought a lot about this and this is the conclusion I came up with. I can't think of 5 times that I recorded live play or vocal and did NOT use headphones. It's either Real Band or direct inputs with the room monitors off. My studio is upstairs away from traffic, and my dog doesn't bark so there isn't a lot of outside noise. I built the gobo mainly to make the vocal environment dead and that thick moving blanket did the trick.
