The "for joy" referred to having wider stereo imaging. Which is something I don't inherently need, but enjoy. My current headphones don't sound as spaced out as let's say HD650.
Uhm.. no. He also mixed Metallica, Red Hot Chilli Peppers, Black Sabbath, Lady Gaga, Bon Jovi, Beyonce, Lana Del Rey, Linkin Park, Justin Timberlake, Limp Bizkit, Johnny Cash, Sum 41 and many more. You'll have a hard time finding many other human beings on this planet with such an impressive portfolio.
But like I said, you're free not to believe in it. Headphone mixes work very well for me too, and they sound just as I envisioned them on any other system, including studio monitors.
Then you're arguing against yourself here:
Also, regarding this
there are many more, but I don't have to list them if you deny my personal experience and of someone like Scheps, there's no point in adding more to the list. Also, it doesn't matter what "the rule" is. What matters is whether it's perfectly possible or not, and it is. Even if 90 out of 100 mixing engineers prefer to mix on studio monitors. That doesn't change the fact that headphones work as well and that some prefer it.
So back to topic:
All I was asking for was a pair of headphones with good measurements, that has a good bass extension (more than 650) out of the box and good stereo imaging.
