I just buy the, I like many robust flexibility (physical) at the headphones, and softness al use (d + after 1 hour of nothing to say .... taff)
the ratio Q / SME seems very good .... was confirmed with time

J before use of headphones (non-pro), and I petes one after the other .... this one seems perfect to me is the level.

Level listening, c is dynamic, clear, very clean and deep.
It does not seem to color the sound.
The sounds are distinct and homogeneous.

To conclude:

The PRO800 is a good (or even very good) purchase
The audio rendering is really correct
The use of very cozy, I put them back on the ears with pleasure after having a puff h
Strength seems more than adequate (my pet peeve with headphones)
Q / P, very right
I put the score of 9 because I haven t enough perspective on pro headphones
Voila.
