Travel Technology - headphone adapters

I was wondering if there was something out there (and I assume there is), some type of splitter where me and my husband can plug both of our headphones into the tv at his seat (or mine) on the aircraft... like if my TV is broken (it just happened to us). At least I could lean over and watch his... Could you please tell me where I could buy something like this... an attachment for the airline plug... so I can plug 2 sets of earphones into it??

Thank you so much!

Anything you can conceive of, and want, and other people might want, you can find it somewhere. eBay is often a good place to start.

I have a Boostaroo: http://www.boostaroo.com/ which provides 3 headphone jacks and is amplified with a volume control. I got it for the amplifier capability because my Sony VAIO has lower volume than my old Toshiba notebook.

Radio Shack is also great. You can just walk in and describe what you need and they will have it 98% of the time. (No financial affiliation with Radio Shack!)
