I have been using these headphones for quite some time now and I cannot fault them at all. They deliver, absolutely crystal clear sound reproduction, are very very comfortable, so comfortable that after a period of time you even forget you are wearing them. They are very lightweight too, so if you are used to having headphones weigh you down, you'll be very suprised by these headphones. The sound really is superb for such a low price headphone. It's unbelieveable that these headphones are under ten pounds. Also, a bigger reassurance is the 2-year warranty.
