much trouble

The unpacked headset was not immediately able to be coupled with a Samsung S5 LTE on the automatic route. Although the enclosed flyer this promises. Only on the basis of a downloaded on the net operating instructions manual coupling could be made via English voice commands. Another annoyance: Despite extensive IT knowledge first could not voice conversion are made through the update function. Under Win7 / 64bit function was not working (apparently an incompatibility with MS .NET Framework). In addition, the system must on no other equipment Plantronics exist (as the advert on termination by the update software). The update software is not a program that could be found in the menu. It's an app in the browser and must be installed again.
Annoying is the support: It does not help as promised within 24 hours In addition, you get the typical answers, with which one can imagine being quite stupid. On the allegation that the automatic link does not work as promised the flyer that I received in response as would have also been that one can download an instruction manual.
For me the headset pushes above. After about 1 hour walking towards pain.
The sound quality was highly praised by my interlocutors during the drive.
I now do not know if I should annoy me that I could be in the car rental that thing on Sunday - and it was of course not be found by the car rental.
