These really are very good headphones. The sound quality is brilliant and I've used Sony before and these are better than any I have used previously. They are extremely comfortable and the different sizes fit brilliantly, without falling out. They really do keep noise out and all you can hear is the music. The cord is slightly too short and with the extension is a bit long, but there is a handy gadget to stop this little problem, as you can adjust it to your perfect length, which is the reason these are almost perfect.
Overall, a great pair of headphones that can be used by anyone!
