Wireless headphones that have a 3.55mm jack?

I need a set of wireless headphones that can be worn for six or so hours at a time. I plan on using them for the TV, the MP4 player, and maybe the computer, because out of all three of them, they all have a standard 3.55mm headphone jack on them. The only problem? I am having trouble finding any wireless headphones that will accept a traditional headset jack.

So if anyone knows of any like this please let me know, and if you know of any that can be worn for four or six hours at a time, that would be even better.

Sennheiser MX W1 but they're expensive, battery life is about 4 hours.

Yeah right...I'm not made of money. I'm looking more of something that costs round $100 or so. Like I said these will be used for at least three or four hours at a time, but their use will be random, so no use investing more than $100 or so on them.

Iogear, Miccus, and Sony make bluetooth transmitters with a standard audio plug. Not sure how well they work with TV though due to the latency issues (delayed audio).
