The first impression from the headphones is excellent, really sit perfectly. They are larger than the MM40 and the cable is thicker. Hearing headphones is brighter with great dynamism. Soundproofing from the surrounding environment is not quite perfect, but noticeable. When the amount and signals of income but expires in background.
