 Just an update on this project. All the electronics have been finished. Definitely, the hardest part of this project has been cutting up and resoldering the audio cable for the headphone.  There is simply no short audio wires, and that completely defeats the purpose of a wireless headset, so I had to figure out another way. One thing to note, some cables do not color-code each individual wire, so it becomes almost impossible to rematch them to solder once you cut the cable. Anyway, I did some research, bought this cable , and reworked it. The next update will be the finished, 3D printed enclosure, and a sweet wireless adapter. Youtube link

I just picked up a 2.5mm to 3.5mm adapter, and everything works great. As long as you're fine with a little Chinese voice telling you that it has powered up, I think that this would work very well. The case is made out of a injection molded plastic, so it might seem a bit cheap, but that is find for my purpose. I'm planning to do a few mods to tailor this piece to my Bose, will post with updates.
