Making Wireless Headphones for the Deus

I just spent the better part of an hour searching this forum for a post and video of someone making a set of headphones from a set using the WS4 adaptor. I also recently saw a video of someone modifying Sennheiser headphones using the WS4 adaptor. Since I just bought the Sennheiser that's what I prefer. Does anyone have the link to either or both of these. I think I can figure it our without them but I sure could like the help.

Thanks
