I own this headset for over a year with almost daily use, it has to face the winter, and all this works fine: C solid!

I'm from the generation''walkman "and I listen to music from my youth and once the headphones on I can tell you that it was' sound bose, so typical of music lovers appreciated, good dynamic , super sound spatialization and enhancement of mixing and every detail of the music.
C hair!

I would do without this choice problem, of course that is expensive but everything is relative and quality, listening comfort are!
