Finally on the highway usable ...

... Because the ambient noise is really reduced significantly. With a connection to the HD mobile (should be activated via headset Software) falls some not at all on the car noise and it follows the question whether one is in the office.
After many headsets finally progress. To much better than the original BMW hands-free system.
The call answer by voice control works and is really usable. The cargo box is a perfect match - which was a surprise for me.

++ DSP - Noise reduction (absolute selling point)
++ Voice control for call handling
+ Announcement of the caller name (if in Contacts)
+ Charger & storage
++ Simultaneous connection to mobile & PC / iPad

1 star deduction for a maximum of mediocre play and cumbersome software. Hope there will be in newer models - especially with the playback quality - something for positive change.

- Earphone audio quality (main drawback)
- Cumbersome software solutions (with necessary online registration for the full potential - for me a no-go)
- The Android apps are divided and complicated - there is one tidy

Conclusion: If the phone a lot for work, makes the purchase of this headset is no error because the main functions work.

Tip for software (with the example, the German language edition is installed, the course pronounce the contact's name):
Installation only works as an administrator. While standing somewhere on the homepage, but not when downloading the software itself.
