I'm a self confessed audio nut and have been researching high end headphones over the last few days.
I came across this link at a headphone forum.

It's from somebody who is a long time high-end headphone user, and owns all the headphones listed, these are the all time best 57 [the ones I bought listed at #21 ]

As I was reading through the list I got to the Ultrasone Edition 10 headphone [which is 5.5X the price of mine], where the author of the list posted this link that another Headphone reviewer, with who he agrees with, posted a video review on YouTube.

I found it hilarious, I think you might as well.
