Pros: Literally everything about it.
Cons: For a comfortable use you have to get used to it but then it is wonderful.
Don't forget that also when you purchase them from German MAESTRO online shop, you can get a 'free' cable or jack modification done by German MAESTRO itself.
Best money ever spent in my whole life. For the ones who wants neutral sound and closed acoustic, you can not get better than these HPs. Also I assure you, these headphones would survive judgment day. Buy it and your grandson will use it years and years later. Now they become signature of me, wherever I go, they are with me.
Ps: I will improve this review but nowadays I am incredibly busy with my master exams. In February I will try to give a more detailed review with the photos I will take.
