Sound: The sound is very good. However, one should note the wearer that the ear pads do not seal the bow of spectacles and thus the sound is negatively affected.
Odour: Because it has already been mentioned by some. The headphones smell after unpacking actually, in my case, neither strong nor annoying, but if you're there, it could disturb sensitive. The actual Geruchsverusacher was with me but the plastic shell of the packaging.
Comfort: hear music for hours is no problem with that, the pressure is quite low which one notices especially when lying down, since the headphones then slide down fairly easily.
Design and processing: Design I really like (but is a matter of taste), the workmanship is very good, but it would have been better a detachable cable with two different lengths to deliver (therefore, there are only 4 out of 5 stars).
