almost perfect
I received my headphones 3 days ago, and I can immediately feel that they are very nice and solid. The sound is excellent, and the volume control is very precise. The comfort is there, I keep it several hours without realizing that I have it on my head. The microphone is removable, so it's not a problem when you're on your own, and there are two types of cable (USB and Jack). The cable is long, perfect.
The only two small negative points: the microphone could have been rotatable or more flexible, but it passes. On the other hand, I'm a bit worried about the leather pads, I've already had helmets with leather and foam, leather gets damaged much faster with perspiration, so keep an eye on it. If the pads had been in foam, I would have given them a 10/10.
