First problem I had to unfortunately find at touchdown. Although two different ear gel ear plugs are, no one wanted to really go well with my ears. Sure the headset is sitting still behind the ear, but comfortable is somehow different. In addition, the microphone is fairly close to the cheek, they touched in some cases. Even after several Umpositionierungsversuchen unfortunately I could not find a satisfactory alignment.
The function test was therefore unfortunately rather sobering. The usage may be super easy, but I was very disappointed with the speech transmission. While I could understand quite well the Gegsprächspartner, I came over much too quiet. The improved significantly, when I pressed the headset to another position, just held this forced alignment of course not for long. As these problems occurred already in a quiet room, I have not even tested noisier environments.
Finally, I can only conclude that this headset is not suitable for all head and ear shapes by far. The alignment is relatively critical for micro and if that does not fit, then the headset is simply not used meaningfully. I have therefore returned and am find anything in the competition for some extra cash.
Conclusion: Ordinary headset if it fits the head shape.
