Sound:
Not too warm designed, more neutral with a slight increase in the bass, but not an exaggerated bass representation
Very clear and treble act not pushy or demanding.
The HD 598 similar but still a tick better. (Specifically, dynamic)
Processing:
++++ Connections processed good
+++ Cable could be even thicker, but is more than just good
++++ Earcups: Soft and comfortable
+++++ Metal casing and volume controls are perfectly
Microphone:
+++++ For a headset, it does not get much better
+ Mute / folding mechanism makes strange something cheap sound when up / down flaps
An absolute recommendation for all gamers and music listeners on a PC with higher demands.
