I'm after some wireless headphones, pref RF ones to listen to TV in bed while my wife is asleep :P

I was going to get a pair of Sennheiser RS120's although I then noticed they are open type, which most wireless ones are. The closed type wireless ones are much more expensive.
So was wondering if I did get open type would sound leak out enough to disturb my wife?

WIll she be able to hear them? If she's awake. probably. If asleep, she'll probably sleep through it unless she's a very light sleeper or you're a very loud listener.

The RS140s are sealed, but also twice the price.
