I use generally use RealPhones, mostly because there's an option to using it outside the DAW when I want to listen to a movie with my headphones on.

The cheapest option I've seen is HoRNet VHS, which will give headphone correction, room simulation and handful of speakers (although "flat" is probably the best option).

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
