In terms of design that is both sober and super class with its glossy look. The helmet is super comfortable with shape memory leatherette ear cushions soft and lighter it is. This only been a month that I have but I do not find it particularly fragile, eventually we'll see. Although I would have preferred to fold and put away in a box, the system of "folding" flat ultimately proves to be something practical.
Most importantly, sound. The headset delivers a fairly balanced, and even to rediscover the pieces Koss pulled too much towards the bass. Mediums are sublimated and pieces of Radiohead or Patrick Wolf eg reveal their soul. Conversely, overcrowded metal songs sound pretty rough, hence the star less. Overall I think its a very good, although different from Koss, and I highly recommend listening to rock in the broad sense, without going into the nag =)
