Amazing headphones from every aspect. Terrific noise cancellation. The detachable microphone is very useful. Sturdy construction and very good sound quality. The only downside, which of course is not related to the device, is the issue with its software, which is no longer officially available from the company and you will have to email their support and tell them that you have this specific issue, and in a few hours or days you will receive an email with the software for the headphones. So you should keep this as a precious item because the link they will send you to download it expires in a week if I remember correctly, so after that, you will have to go through the same process again.
