Einfacher als Zusammenstecken geht der Aufbau auch ohne Anleitung. The ear sections (headphones?) are not noise cancelling, but I do notice that the furnace is muffled when I have the headphones on. I bouth everything from them, cables, chargers, headphones, power strips and everything worked amazinglyHowever this PowerPort failed me big time. sound quality is decent and plenty loud. Both of these methods are relatively quick, but are very expensive. But handles poorly. As a Sennheiser fanboy, I really wanted to love these but unfortunately I couldnt wear them for more than 20 minutes without the plastic headband digging into the top of my head. The microphone is very sensitive and although I am a rather soft-spoken person, I sometimes have to move the microphone/boom far away from my mouth to match my listeners comfort needs. We did add a few of our own bungee cords to keep things secure, but they really may not be needed. I highly recommend this product if you want something that is comfortable and compact.
