You have to try these out to really understand the immense degree to which these headphones carry. Differing from the older noise cancelling, you can still listen to these headphones even with the noise cancellation turned off. In addition, they fit so snug that you literally forget you have headphones on. Now with the noise cancelling - its major selling point - I can attest to the fact that indeed not even my rotten dogs themselves whom of which are total reprobates .......can bark loud enough to break through to my ears when I have those on. Listening to music is just a gas for me with these or even recording also works extremely well with these headphones. Since they are closed back, I tend to use them during tracking and not so much during mixing. Either way you have to get a pair of these. Bose has established clout and leverage and esteem with their name for many decades. you cannot go wrong with these babies. Get em and you know what? If they get worn out or break Bose will actually just send you brand new ones for like a fraction of the retail price. The warranty is amazing. Anyway, just don't overthink these headphones, get them and you'll understand why I write this.
