Listening to open-backed headphones and speakers simultaneously?

Anyone try it? How's it sound?
I guess I have too much time on my hands.

It will still muffle the loudspeakers.
I have inadvertently left my subwoofers, but not my speakers on.  I don't recommend it.  
No no no.

if you want headphones just sit 3 feet in between them atc’s and point them directly at you.  Your wife will realize you’ve finally lost it and ease up on you.
