Personally I bought the Z700 MDR some time ago, the sound is the same as the V700 (that is excellent!) And there are many registration jack on the Sony and the headband. So is Sony made an update of his headphone by adding badges or there are many counterfeit headphones.

How long have you use it?

About a year and is well despite the rumors.

- What is so special that you like most and least?

Most:
Excellent sound-
-Comfortable enough
-Excellent design

The -:
-A little too heavy, shakes his head a little too
Graves, a little too forward.

- Have you tried many other models before buying it?

The MDR V700 has the same sound.

- How would you rate the quality / price?

Excellent

- With experience, you do again this choice?

I do not know. I would have more points of comparison to see if there are better or not.
