Necopotence

I recently came into the habit of watching DVD on my computers with my roomates. My problem, however, is that I have a hearing impairment that makes it extremly difficult to hear the audio from the speaker if i'm any father away then maybe 2 feet.

I was wondering if anyone could suggest a set of wireless headphones that would allow me listen to the audio while leaving the audio playing through the speakers. I've been looking on-line for reviews, etc. but I can't seem to figure out if all wirless headphones have the correct I/O to allow for the audio to still come through the speakers while I listen with headphones.

Do I need to order a special pair of headphones that have enough I/O or whatever (I'm not audio eqipment savy as you can tell) to meet my needs? There is nothing quite like totally phasing out because you can't hear whats going on while your friends think they are watching the best action film ever.

Here is an example of what I'm looking for, but unsure if it will allow me to listen while others listen through the speakers:
