Pros: Superior sound and fantastic noise cancelling feature.
Cons: Pricey.

I've had these headphones for a few years, I use them for work and pleasure. The noise cancelling feature is fantastic for flying or any noisy environment, until you try them, it is hard to imagine just how much background noise they reduce.

The quality of sound is superior when listening to music. I found it amazing just how good they were when I compared them to a rather expensive knock-off brand that I have and loved....until I got the Bose that is! I also use them for the transcription work that I do, the quality of sound is so superior that I have a much easier time listening to speak, even hard to understand dialects, then using any other headphone. I am simply lost without them at this point!

Even with extensive use, I have never had a problem with them. They do use only a bose stereo cord, no others I've found will work. But even when I've had to replace this cord, I received it within 2 days, and the customer service staff at Bose is wonderful to work with.

If you have the opportunity to get these headphones, you won't be sorry.
