Finally a headset, with which I can well call and the USB port just works.
The sound is so great that I have asked about it my interlocutors that I have changed.
The headset is super light, so it is hardly noticeable when worn.
Extremely important to me is the good workmanship. After I had been 3 Logitech products with inadequate processing, can fully develop the quality now.
There is the possibility a Reisetacshe, if you want to fold it, which is also doing very well. In my case that is not necessary for happiness. For the journey on the train or plane, I can only recommend headphones that have active noise cancellation.
Gladly Again.
