manufacturing quality is impeccable! it's tough. As I said in another post, this headset fits comfortably on the head. It is comfortable, provided you do not forget it's there. I have a Sennheiser in my living room that has happened to me to forget after a 1 / 4h it will not be the case for this Philips. On the other hand he holds hot ears. In sound, there are still quite low. However they do not crush the rest of the spectrum. A small equalizer and the result is excellent.
In short: a very good helmet at the level of the sound of construction
