It seems like the worst measurement for the Ed8s is the THD measurement for the sub-bass. It should be a good idea to remember that closed cans have a harder time controlling the bass, inherent by their design. Sure, the LCD2 and HD800 trounce the Ed8 here, but it's like comparing apples to oranges, despite the prices.
On the other hand, Beyer's T5p puts off a good fight against the ED8s.
T5p
More treble, but apparently not the T1 way
Deeper bass
Less distorted bass
Bettet isolation than Ed8s (wasn't expecting this)
Ed8
More neutral sound sig
Smoother/Rounded off bass
Better Impulse response
Less ringing
It's decided that Currawong doesn't like it, while some other people do, like MacedonianHero. For people who absolutely need premier closed cans for isolation it's mainly the T5p vs the Ed8s: so pick your poison.
It's a shame the Cost/Performance ratio is so terrible for both cans.
