What kind of headphones should I choose?

I wouldn't give any credence to the linked article, which contains too many generalizations. 

 

Many people, I would even say most, prefer a headphone with boosted midbass (e.g. Sennheiser HD 650), but it really annoys me. Some people are very sensitive to treble, whereas I prefer a headphone with lots of airiness and detail, showing as a bit of a treble spike on a FR graph (e.g. Beyerdynamic DT 1990 Pro). Some headphones are thought comfortable by some, but tortured me (e.g. Grado RS, Hifiman HE). I have a friend with an expensive Audeze planar that he loves, but to me lacks PRaT, something I consider above all else.

 

Obviously you need to do some research, as you are, but the best way to compare headphones is on your head. Sonic preferences are very individual, possibly more so with headphones than anything else in audio. Physical comfort is extremely important for extended listening, and everyone's head, ears and tolerance levels are different. Can you get to a store for some trials?
