Very user friendly, open case on, close it off. Heck, I might buy a few more just to have as spares! IMHO they are not nearly as good in the clarity, effortless reproduction and neutrality of even the middle tier headphones from AKG or Sennheiser, HifiMan, etc. Very good quality and comfortable fit as expected from a Diesel product. Just got these yesterday for my husband. My only negative comment is that the hinge of the kickstand when in the down position has a small amount of play, very small. I got a Medium. Definitely my go to to just throw on and wear around the house or to go out for a quick walk. First, the overall quality is quiet nice. Ce nest évidemment pas un casque pour mélomane averti.
