Whether in the open-plan office, bus or plane ... I always have my rest :)

The headphones come with a price have these in my opinion but worth it! The sound is Bose-like (I like it), the processing goes so far also clear only the cable connecting jack and the battery pack could be handsome, looks like a shrink tube, but that does not bother me.
The Noise Cancelation function is really great, in the office while working with the headphones I hear neither my colleagues nor the keystroke my keyboard or clicking the mouse. Standing colleagues right next to me and chat, so that sound, as people would like to chat in the hallway with the doors closed, it takes only a slight noise was, but the conversation can not even follow you. I'm excited!
