The build quality of this headphone is very impressive, most is of the shares are in metal with leather. HOWEVER the quality of 2 Supplied cables are not so good, the buttons are made of cheap plastic and the cables are very rigid order the plugs are very good. In terms of comfort, I bought this Because I have a small head (I can never find a cap That made my head, I am a male 1.70m) and over the ear headphones are just too big for my head. This pair is on the ear and on the Smallest setting it just sit on my head Would not it intended stay very still if I move too much of my head though, I can wear it walking in the street. Sound is the best of the headphone, very large sound Such a small training for drivers. Base is not as hard as the BEAT qui I prefer. The mic est very clear for use with mobile phone. Noise canceling is ok, I have used it on long haul flight and it keeps MOST of the noise out. There is still improvement in this headphone. Purpose Otherwise They Are Nearly as good as the AKG Q460.
