The sound is excellent to work without dnaturer or transform. This is a headphone with a lot of prsence, with a super bright restitution. The price is the height of its quality.
In addition, the possible dvisser big jack mini jack your checks is a bright ide sony (may be other brand so I do not know).
Voil is the headphone almost perfect but be careful because when even after long hours of work slowed down, ears and runs a headphone because it was closed so you think ARER ears often!
