So we're in a situation where we have to share a room with the baby for several months. We'd like to be able to watch TV after she goes to bed without waking her.

preferences:
Two pairs of wireless headphones with a single base station.
RF or infrared is fine, but I'd rather stay away from 2.4 Ghz.
I'd like to keep it under $200 if possible.

If you don't know anything about this, but you could point me toward some good review sites, I can do my own research...I just don't know where to start.
