A week of use.
I have read the previous articles and opinions are highly variable and spend "very good" to "a stew unnamed" ...

If you need a headphone "HiFi" to listen to your MP3 or listen to your mix console, sound may actually seem bad because it is a "neutral" headphone ...
That is, it restores all frequencies linearly.
Traditional headphones will conversely boost certain frequencies to flatter the ear (bass and treble)
The sound "boardy" is linked to this answer mode.

I tested other headphones more vocation "DJ" but less monitoring. (See above!)

I use it for a week and the frequencies are actually well balanced.
We hear very distinctly different instruments in the mix (computer music).
The bass is precise and not drool.
The headset is comfortable to wear and the neutral restitution does not tire the ears.

Very good quality / price ratio.
A remake yes ...
