Actually I spoke with Axel at Sennheiser myself. He confided that the upcoming (spring 2014) HD850 will include a trepanning kit. The new 18mm drivers will be implanted through the cranium, behind each ear. Finally, a single, 43mm sub-harmonic enhancing driver will be implanted in the rear or top of the skull. This wireless system will run on the 2.8khz Kleer system, and link to Sennheiser`s new 24/192 streaming system. The antenna will be a few hair plugs, positioned where ever the user wishes.

I helped Sennheiser design the new flagship, and you have
completely misinterpreted these documents. (Frankly, I'm concerned that you were able to get hold of these at all, I suspect the R&D database may have been hacked!)
We wanted to dramatically expand the soundstage for the new phones, and merely changing from SE to balanced connectors just wasn't going to do it. So we have designed a new connector which plugs
directly into the artists' brains! "From the mind of the musician and right to you!" (TM). The attached documents show some of our artists being fitted for the connection, all for your listening pleasure.
Plus, we extended the bottom end.
