Ultimate Wireless Headphones

I live in an urban environment and as such I am often walking, into and out of cars, buildings, etc and so I frequently listen to music on my headphones. I also travel work my work and some of those flights can be very long. As such I want to have noise cancellation to my headphones. I also want to increase the usability of my current headphones. The cord can be annoying but I also can't take calls on them or control music playback. I want all of this without compromising the fidelity of the playback. I want my cake and eat it too... but what does that look like? I did an extensive brainstorm and this is what I came up with. To date nothing like this exists but I think in the next year or two we'll have something close.
