I tried these headphones on in the shop, along with the older version (AE1's), Beats by dre's, and several of the other Boses and these gave such a better sound than all of them in my opinion. The bass is really defined, without being overpowering, you actually hear so much more to the song when listening on these.. Amazing sound.
I have had these about 3 months, i use them most days and would honestly say that they are the best headphones i have ever used... They say they are not noise-cancelling, however, when music is playing, you cant hear people talking in the background atall.. Not worth the extra £100 or so for the noise-cancellers in my honest opinion.
These headphones have a nice, quality feel to them, adjust to the shape/size of your head, and are so comfortable to use, even for a few hours.. And best of all, great sound!
Overall, a great product which i am pleased i purchased. I would recommend to anyone...
