Pratiquemment found today.
Used by all sound engineers.
A clear, transparent with a hellish dynamic (BP 5 to 30khz and 106 db / mw!).
The entire sound spectrum is superbly set (not the low left)
I had the opportunity to try moult headphones brands in this field but frankly MDRV7 crushes them all.
The foam ear a bit to start éfriter after 14 years of loyal service but the sound is still magic!
If you find in secondhand for it!
PS: The picture shown is absolutely not good
