If even a microphone this would ...

... There is the 5th star. Headphone / microphone is nowadays a "normal" combination, whether smartphone or PC. The headset fits well, has a good quality and esteems one day by the computer. For sound, I'm certainly no expert, but that is better than the Apple headphones. The microswitches are certainly troublesome, so the unit has been set "maximum quietly" on delivery to, try only after it worked, it was an arduous hurdle. Despite the color, it is unobtrusive!
Very satisfied, but again I would not buy the headphones, simply because the microphone is missing. It is therefore certainly no "permanent solution". My notebook switches eg. By Skype automatically to "internal" (speaker + mic) = loud, just as the smartphone, for example. FaceTime ... It's annoying, because the headset is supposed to ensure that it disturbs others do not. Therefore one star deduction and further search for a "better solution".
