Pros: These are a very comfortable and light weight set of headphones. They sound great and are easy to adjust on the fly.
Cons: A couple of weeks of use ( burn-in ) is required before optimum sound performance is attained as the bass is lacking out of the box. Those unfamiliar with audio equipment burn-in should suspend their disbelief and consult the numerous professional discussions on the topic. If nothing else, don't judge them out of the box as they do sound noticeably better and more open after several weeks.
Overall Review: Highly recommended.
