For me the sound and the voice quality is super important music at work and in telcos and go well understood. All this, unfortunately, does not meet this set.
1. The plugs are huge, you do not have big ears (as it sounds :)) push the roughened rounded ear, which is inconvenient and not a good wearing comfort.
2. The Micro is contrary to many other not above but on the side of the front panel. This has the consequence that you never purely speaks directly, but rather ambient noise and are captured mainly wind. Therefore useless phone while walking. In discussions it was always not hear everything around which but you. Now I do not want to hold the whole time with his hand the microphone to his mouth also, because I might as well call so.
Too bad, because 1 star for the super price and beat another for the hammer equipped with accessories that you need for now. However, help you at all, because before you scores with equipment should be the basic homework and that happens unfortunately in my opinion not.
