Convert wired headphones to bluetooth

Here is what I want to ultimately do: I want to turn my Bose in-ear headphones into wireless bluetooth headphones. 

I was thinking that I could attach the wires to a small bluetooth receiver and presto. I want something small and lightweight, so the Belkin thing is less than ideal. I want it to be able to hang around the back of my neck much like the Jaybird FJ3MB Freedom headphones. 

Any thoughts? What materials do you suggest?

I have a sufficient amount of technical know how, so soldering and stuff shouldn't be a problem.

Just for clarification, here is exactly what I want to make, but with Bose headphones and pairable to any device:

Uncle Erik, 

Can I get an amplifier/receiver combination that I can integrate into the headphones?

Another thought is that I could buy cheaper bluetooth headphones and remove the bluetooth aspect and transfer it to my Bose. What do you think?

Something else that is potentially problematic is the little plastic oval about an inch or two from the jack on the Bose (btw they are the IE1, not IE2). What is that? Does it enhance the sound quality? So would it be needed on the bluetooth headphones? 

I don't really want to use a small device or something, because I would still have the same amount of wiring.

Thank you!

Mark,

The reason I want to use Bose is because of the great sound quality and comfort. And because I have them. And here I thought this forum would be kind and helpful to newcomers instead of mocking their questions.

also i wasnt mocking your question.  you seem wedded to the brand even thought they dont make what you want so why not ask them?

I didn't think it mattered why I wanted to use Bose so badly, but I guess I will explain further.

There are only a few semi-decent bluetooth in-ear headphones on the market. Even fewer are compatible with all devices. Most of them have questionable sound quality and comfort and are styled in a manner most unpleasing to me. My Bose in-ears are, I KNOW, very comfortable and have great sound quality. So in other words, if I could make bluetooth headphones exactly how I wanted them, they would be exactly what I want, and that would be nice. And the headphones that are exactly what I want are only compatible with Sony products. 

Uncle Erik,

If I could graft another system into mine, it would be worth it if I only had to spend something like 20 bucks more instead of 75 ish in order to get something that is high quality enough for my standards. I haven't tried a lot of other manufacturers, but I have tried Apple's (of course); Skullcandy in ear and around ear; Sony in ear, around ear, and noise canceling around ear; and Bose in ear and around ear. From my experiences, I like the Bose best for it's quality and comfort. The around are were awesome, but the in ear are more practical $$. The Sony MDR XB20EX were pretty nice, but not very comfortable for me and I didn't like the sound quality quite as much as the Bose. Based on this, is there anything you recommend?
