Very comfortable and good quality headphones. The noise cancelling is amazing! Walked around a shopping centre and the ANC made it seem like i was walking alone in silence, then switching modes it's amazing to hear the difference. Sound quality is typical BOSE, very clear and beautiful sound, though bass doesn't pop too much. However, it depends what sort of person you are regarding expectations of sound.
Call quality is where it is amazing, I use it for my mobile calls in the office and it is amazing.
