But you're blocking your ears off while using an outside source, it makes no sense. You get no benefit from the better quality of the speakers when you're just covering them up with your headphones.
I don't think you've ever set it up like this. It works out really good. It works out way better than having everything straight through my headset. I don't want the music or video I'm listening to be the same volume as the voice.
On top of this my headphones aren't designed to listen to music, they're made for voice. My speakers still sound better than my headset. I have a real setup with a subwoofer and all of that.
It gives out much better sound than the headphones. My headphones don't cancel out all noise or anything, I can still hear everything pretty well. The mic also doesn't pick up anything outside of my voice unless it's really loud.
