These headphones are highly recommended. It is light and very comfortable to wear. I got it for several hours at a stretch on and there had suppressed nothing. The earcup surrounds the entire ear. The sound quality is absolutely top (depending on the output device is a slight background noise perceptible). The plastic parts are processed dibasic. The open design phone and doorbell are still good to hear. This makes him, of course, unsuitable for use in noisy environments (is after all no ear muffs). The cable is about 3 m long and an adapter to 3.5 mm jack is included. I like him very much, and use it almost every day, therefore, full marks.
