For the short time I had these headphones, I fell in love with them, and Skullcandy as a brand. Sound Quality The sound quality was pretty good, regarding the mid-range and treble, but if you turned up the bass too loud, the bass quality went to crap, and so did everything else. Great sounding quality for bass music, and heavy metal. Also great for gaming, because you can hear every tiny detail of a sound. Great at cancelling noise. Comfort Mainly a matter of personal preference, I found these headphones to be very comfortable, mainly because the articulating earcups adjusted to my large head. Design I really do like the design. I think the folding design was genius, but really ahead of its time, because it very much compromised the durability of the headphones. Durability Really, this was the only thing I was disappointed about at the time. The articulating earcups are usually associated with DJing, as it makes it easy and comfortable to monitor and cue/drop in new songs. I could see these headphones being marketed to young DJs like myself, but the flimsy plastic headband was an incredible turn-off to me, as well as the small, flimsy, cords, that happened to not be able to be replaced. On my first set of these headphones, one of the cords got ripped out of the driver completely. The headphones were practically unusable, as only one driver worked. On my second set, the wire became loose, so all you could hear out of the left side of the headphones was the bass. Believe me, it did not sound good.
