Contrary to some opinions here I find the device absolutely top. The operation is relatively simple, after ~ 10 minutes one has so far everything under control. There is also a separate app for smartphone (at least Apple iOS => JabraConnect). This I also succeeded, as you all functions that you would otherwise have to adjust the headset easily can use it to perform over the phone. Charging time is 2 hours. That's my opinion perfectly fine. Pairing functioned without problems. The first-time right Adjust Headset regarding fit and touched down with one hand is a little expensive, but if you can once and has the hang of it (after 10-20 tests) it is quite easy and very pleasant sitting. At first it was to be a little unusual, because it is more flexible than the typical headsets. Meanwhile, I think it's very convenient because it thereby allows pleasant adapt to the ear.
