Pro:
+ Very spatial and detailed sound
+ High volume levels possible
+ Very light and therefore comfortable to wear
+ The 3m long cable provides great freedom of movement
+ Great design!
+ Extremely good price / performance ratio!
Cons:
- Though typical of over-ear headphones, but very poor shielding to the outside (Present hear people in the room with everything)
- The sculpture seems unfortunately not very attractive; it looks "cheap" from.
For sound:
The headset is tuned very neutral. To my mind there is no adjustment via software / equalizer too little bass. If the low frequencies but raised in software something you get great sound experience with very deep bass for the money. I'm using the headphones at a high-quality PC sound card, so I can not say anything about the volume levels of mobile devices.
